32 experts talk about 31 persons of domestic rubbish disposal

32 experts talk about 31 persons of domestic rubbish disposal " Mainly burn " Burn in order to mainly bury it in order to complement
It is reported yesterday afternoon, two - day " expert's consultation meeting of domestic rubbish disposal of Guangzhou " Over formally. In the advisory opinion of the expert that forms subsequently, except an expert thinks it is risky that the existing rubbish burns technology, other 31 experts participating in the meeting all think Guangzhou should be adopted " Rely mainly on burning, it is complemented that landfill is " Domestic rubbish disposal mode. These 32 experts participate in this consultation meeting invited by government of Guangzhou.

The expert panel thinks, if the rubbish will be burnt, must guarantee to supervise in place, guarantee to burn the steady normal running of system, the monitoring data are true and reliable. Propose increasing the transparency supervised, let the public not merely participate in the environment assessment of the project, still can participate in operation and management after the rubbish treatment facilities are built up.

Expert opinion

Handling

Suitable for burning it for main landfill in order to complement

After the meeting finishes, expert's consultation meeting notification of domestic rubbish disposal of Guangzhou will be held immediately, sea cloud Xu, chief engineer of research institute, group leader of expert panel and urban construction of China, vice group leader of expert panel, Professor of Tsing-Hua University Department of Envorinmental Science and Engineering Nie can participate in, notify by Yongfeng and the intersection of expert panel and vice group leader, the intersection of Zhongshan University and environmental science and ShiYu Li, dean of project.

Xu HaiYun reads out the advisory opinion of the expert that has just formed at first - --The expert panel thinks, the management of the domestic rubbish implements the source decrement at first in principle, produce little domestic rubbish as much as possible; Secondly recycle resources to the domestic rubbish produced as much as possible, include as much as possible until can organic matter of biodegradation go on carrying out a biological disposal upon; Burnt and deals with and retrieves heat energy the rubbish on this basis; Handle landfill to the remainder finally.

As to the intersection of population density and old, the intersection of urbanization and horizontal excessive growth, can use as the intersection of land resource and scarce Guangzhou of landfill yard, the expert panel thinks the expert panel should accelerate the modernized domestic rubbish and burn the construction of the factory, the modernized rubbish burns the prior choice that technology is domestic rubbish disposal of Guangzhou, should adopt " Rely mainly on burning, it is complemented that landfill is " Domestic rubbish disposal mode.

The expert panel still thinks, according to practising both at home and abroad, the domestic rubbish can reach the discharge standard that the country stipulate while burning the disposal of pollutants of the treatment facilities, it is controllable that the modernized rubbish burns the pollutant of two Great Britain,etc. produced, the environmental security can be ensured.

But have an expert who thinks in 32 experts, the existing rubbish burns technology riskily, the domestic rubbish disposal of Guangzhou should choose to recycle to the greatest extent, adopts the new technology craft, should not choose to burn and deal with blindly.

Burn and supervise

Advise the public to participate in the operation and management

If the rubbish will be burnt, how to guarantee to supervise in place? The expert panel should install the advanced one in line control and monitoring equipment while thinking the domestic rubbish treatment facilities, guarantee the steady normal running of system, the monitoring data are true and reliable. Meanwhile, should make the environmental emergency preplan, implement the environmental risk accident preventing and emergency measure, prevent the occurrence of pollution accident.

In addition, the expert panel also propose increasing the transparency supervised, set up to the public? Revolve Ge pay tired blind , U of , to closely question, make rose of Sharon Does put down Bei and deceive and revolve Rong Hua 's phlegm and raise and teach Lu's beer?

Nie Yongfeng, vice group leader of expert panel, further adds, it is really a relatively weak ring to supervise at present, and the public is to supervising the worry of the existence, there is certain reason. "But I think, technically, disposal of pollutants reaches the national standard, it is possible. "

Nie Yongfeng has also put forward the concrete suggestion of strengthening citizen's participation: "The public just can be participated in at the environment assessment stage of the project in the past, but I thought, the public should also participate in operation and management after building up of the rubbish treatment facilities, for example we imagine that be able to establish and supervise the committee, members include ordinary citizens, in this way, can carry on supervision to the supervision of the corresponding functional department, give play to public authority to supervise and right of being in know. "

Rubbish classification

The harmful rubbish of family should be separated

Say as to the intersection of rubbish classification and sea cloud Xu, expert set up, discuss reality of city whether existing the intersection of waste recovery and rubbish of way of a certain degree classify and combine together the intersection of developed country and experience and Guangzhou that rubbish classify, choose to accord with the real rubbish classification method in Guangzhou; And make and have economic and effective categorised collection relevant policy and concrete method of domestic rubbish.

In promotion of rubbish classification, the expert panel thinks the expert panel should pay the utmost attention to the classification of the harmful rubbish of family, the government sets up categorised collection system, and try hard to reduce the moisture in the rubbish, promote the management of the organic rubbish of biodegradation as much as possible. Though the harmful rubbish of family is not produced every day, if does not carry on categorised collection, and mix with the domestic waste system, impact on domestic rubbish disposal and environmental hazard are all obvious.

Have management of rubbish more organic to biodegradation, the expert panel has proposed three kinds of alternative typical modes: Germany's mode (collect and carry out a biological disposal upon alone) , U.S.A.'s mode (adopt the family pulverizer to drain into the sewer) With Japan's mode (demand to reduce the moisture as much as possible, burns and deals with as the bionass) ,Guangzhou city adopt which kind of mode need, carry on systematic research and propose feasible scheme at first specifically.

Sound

Sea cloud Xu, chief engineer of research institute, urban construction of China:

It is ripe to only burn technology at the present stage

Should support the new technology boldly, but the technology that only burns at the present stage is ripe.

Issue, Yunchang of sea, Xu, chief engineer of research institute, urban construction of China, study solid the intersection of waste disposal and field, been maintaining all the time the rubbish is being burnt, at this consultation meeting, China where he has been happening and opposing all the time the rubbish is being burnt surrounds the institute retired researcher Zhao ZhangYuan of the department to assign in a group. These two people get together, everything will happen, it is believed that everybody will be very curious.

At yesterday's circular meeting, there are reporters that asked: "An expert thinks, the existing rubbish burns technology riskily, should not choose to burn and deal with blindly, is this expert Zhao ZhangYuan? Whether it is 31 experts left, all think it is the first-selection that the rubbish is burnt? " Xu HaiYun has smiled, the definite reply that have given. To why the intersection of chapter and yuan Zhao come, can participate in, notify, host explain arrange group leader, vice group leader of expert panel as representatives only, so there is no Zhao ZhangYuan.

While mentioning to Zhao ZhangYuan's view, HaiYun Xu say oneself and Zhao happen to assign to a group, everybody has fully published one's own view, " view not just agreeing, but we have all expressed one's own attitude on the basis of fact. "

As to the thing that the intersection of chapter and yuan Zhao put forward several the intersection of new technology and craft that adopt, HaiYun Xu think, should support boldly to the new technology, but the technology that only burns at the present stage is ripe, " in my view, these new technologies do not all have a successful case, still at testing stage, not so ripe that used in the project. "

China surrounds the institute retired researcher Zhao ZhangYuan of the department:

The voice which objects to representatives is too faint

Hope such an expert's discussion does not go through the motions, but really offer the beneficial thinking for rubbish issue of Guangzhou.

After the meeting, it is expressed when being interviewed by reporter that China surrounds the institute retired researcher Zhao ZhangYuan of the department, this is that he participates in expert's hearing of garbage disposal organized by official side in Guangzhou for the first time. The government of Guangzhou considers about citizen's responsible view, organizes this expert's hearing, it is worthy to be definite. But he has not expected the experts' view is to maintain the rubbish is burnt with the overwhelming advantage, the voice which objects to representatives is too faint.

He still shows, once participated in the similar expert to know in Beijing by oneself, its result and course and Guangzhou were very much the same.

Zhao ZhangYuan does not think the view of opposing the rubbish burns that he maintains has got enough attention, with mainly burning and sending the expert's view to cross swords, though the personage's respect that his opinion can get a lot of and participate the meeting, but the respect is exchanging privately, it shows that it is not many to support to have a clear-cut stand in the meeting discussion.

"Hope such an expert's discussion does not go through the motions, but really offer the beneficial thinking for rubbish issue of Guangzhou. " Zhao ZhangYuan says.

Focus question

Should burn or bury at the present stage?

"Without anything ' burn and send instead ', I do not object to burning either. " China surrounds the institute retired researcher Zhao ZhangYuan of the department to say at the meeting, do not specialize in rubbish by though oneself, but it was environmental protection that studied, the ecocrisis bears down menacingly at present, as the potential pollution sources, garbage disposal should rise to very important position to consider. Is it what is burnt that the rubbish burn the key? He does not maintain that burn and mix the rubbish, after but should deal with harmful rubbish and plastic classified reclamation such as the rubbish of kitchen cabinet, battery firsting, the remaining rubbish can be burnt. Before not being recycled effectively, can consider adopting domestic rubbish of technical treatment such as hydrolyzing, plasma technology and consuming oxygen to ferment of the high temperature.

Is the technology feasible at the present stage? "The high temperature actually hydrolyzes a kind of false technology, because its balanced philosophy of violating heat. Not talking about the noise pollution, the vapor produced in the boiler will be turned into a sewage. " Key laboratory (Shenzhen) of the recycle economy in Peking University Director Liu YangSheng speaks with the truth, he has ever measured this kind of project, the sewage composition produced finally is more complicated than the rubbish. Biotechnology of fermenting etc. is unripe too at present to consume oxygen, and high-temperature plasma decomposes technology and is used in the spaceflight originally, still need to cut apart the rubbish and paying and decomposing to several millimetres at the stage of trying to find out at present, do not possess the holding in fact temporarily.

Landfill of hygiene, burning and biochemical compost, it is most three kinds of generally acknowledged main rubbish handling of expert participating in the conference. Returned scholar, environmental dean Liao Li of Central China University of Science and Technology introduce at the meeting to study in France, because national character is comparatively free and bold and unrestrained, France is very little when pursuing the effect for many years of rubbish classification, 30% of the rubbish adopts and burns dealing with at present, about fifty percent adopt landfill to deal with, 1 relying mainly on rubbish of garden adopts the biochemical compost way as rubbish. Landfill or burns and chosen, fill out or burn and depend on the land resource by a mainstream of world developed countrying.

Researcher of Chinese Academy of Social Sciences, Guangzhou institute for economic research Guo YanHua speaks with the figure, calculate according to the models, if all adopt the landfill mode, Guangzhou needed about 198.6, 408.2 hectares of of area and 621.8 hectares respectively in 2015, 2020, 2025, face not having usable awkward situation of ground. Adopt the value compensation standard of economics to calculate, the cost of landfill is about 2,250 million yuan - 4,500 million yuan, burn it for 1,800 million - 2,500 million yuan.

"At the end of the 1990s of last century, having developed many small-scale incinerators at home, but the insufficient problem of all forming a complete set. It has been already more advanced that the domestic rubbish burnt technology now, the pearl trigonometry has such condition development too. " The Professor of Department of Envorinmental Science and Engineering of Tsing-Hua University thinks while celebrating in vain, Guangzhou develops rubbish to burn inevitably, need during planning Conghua, flower, Fanyu, Zengcheng,etc. include in the range of the whole city and consider every possible angle.

Southwestern Communications University's environmental science and institute's professor Zhang WenYang of the project express, observe comparing in Germany and other places, the rubbish that our country introduces at present burns technology according to it, including exhaust gas cleaning technology, it is basically the most advanced in the world, do not eliminate technology, is worth popularizing.

China Meteorological Administration the intersection of Guangzhou and tropical meteorological the intersection of research institute and chief the intersection of researcher and Wu add thinking, the present craft of landfill yard of rubbish has resulted in producing a large amount of methane, the source emerges as another large greenhouse gas in our country soon, set out from reducing greenhouse gas emissions, it is comparatively rational to choose the rubbish to burn.

Landfill and burning the third option

Except landfill and incineration, how to popularize biochemical compost treatment technology, it is focuses that many experts think too as the third important option of garbage disposal.

Professor of Tsing-Hua University Department of Envorinmental Science and Engineering Nie Yongfeng says, present rubbish landfill technology consumes a large number of land resources. The high density PVC membrane service life when is generally adopted is less than 30 years, the rubbish is after detest and ferment in oxygen environment, the heavy metal will delay reflecting to permeate through soil and underground water pollution question. For burning technology, because the pollutant of landfill is not easy to measure, the pollution of the peripheral ecological environment may be greater. Proceed from national conditions, the coastal developed area has a large population and a few land, the socio-economic development of the city has determined our country adopts and relies mainly on burning, rubbish management mode fully recycled to the useful rubbish. It will must notice my rubbish of kitchen mixing the question causing the fertilizer to be polluted with ordinary rubbish to develop biochemical compost to deal with. The compost use is quite limited after the heavy metal is mixed with poisonous organic matter. This kind of fertilizer can only be used in the ordinary nutrition soil that afforested, the mode purchased in unison by the government, except this, it is little that afforest outlet in the land of nutrition in the city at present, the utilization ratio is not high.

The new fertilizer chief of research office, professor Liao ZongWen of environmental institute of agricultural university resource in South China thinks, a reality that can't be ignored is at present, the rubbish is turned into the fertilizer can only be a garbage disposal auxiliary channel in our country, but not main channel. It turns garbage disposal into producers of the fertilizer that much at present, or the fertilizer is not done well, or is in the state of losing management. He finds, also contains the glass particle in the fertilizer when being some rubbish in Beijing is turned into the treatment factory of the fertilizer to gone, but such glass particle does not pitch the foot.

Shanghai environmental group technological director Zhang Yi expresses, our country once stood side by side compost and landfill as two major garbage disposal main ways in the eighties of last century, but thereafter entered " Puzzled one in 10 years " ,More than 100 compost projects get down from horse one after another. Much except impurity, heavy metal exceeds standard, foul smell is seriously polluted, the fertilizer efficiency is unstable is one of the reasons too.

The environmental science of institute of technology of South China and institute's Vice President Wei ChaoHai of the project are inspired from sewage disposal, in treatment of the industrial sewage, the waste water is used and carried out a biological disposal upon first, then use the chemical method, this may be offered for garbage disposal and drawn lessons from the method. The rubbish in Guangzhou can be disposed of a part by way of biodegradation first, then add the auxiliary material, burn again, the residue left carries on landfill.

Expert: It is more possible that my rubbish of kitchen burns Great Britain of production two

Two Great Britain burns and disputes the hot vocabulary in the swirl in the rubbish. At the consultation meetings of two days, the experts produced reason,etc. and discussed to two Great Britain.

"The Dutch scholar Olly1977 annual test in the rubbish burns the exhaust for the first time to two Great Britain. " Zhejiang University the intersection of heat energy and the intersection of project and the intersection of research institute and energy clean and utilize national key laboratory Professor Li XiaoDong to reveal, Olly shows in a memorandum that Zhejiang University does, it shows to burn the experience through the rubbish of more than 30 years of Europe recently, it is the best rubbish handling so far to burn through the rubbish of effective management. However, the rubbish of European Union burns the rubbish calorific value that the factory is used in burning and reaches 11000 joule(J)s / kilogram, the average calorific value of rubbish that and our country is used in burning at present is 4000 joule(J)s / kilogram. My water content of fresh food kitchen of Guangzhou area is high, rubbish calorific value is lower. In order to prevent dust,etc. from discharging things, the rubbish burns the craft and does not add the auxiliary fuel (such as active charcoal) in the course of burning now ,Also unable the rubbish of improvement burns heat by a wide margin. The rubbish of low calorific value burns to lead to the fact two possibility of Great Britain is really greater.

Chinese Academy of Sciences Guangzhou take Deputy Director, the intersection of researcher and Peng think safely, two Great Britain should pay close attention to continuously, but needn't be afraid. On the basis of classifying rationally, control and can control two Great Britain effectively online in burning the temperature in the course. Measure, find in China, two most big source that Great Britain produce the rubbish is burnt, but come from the metal smelt trade.

The environmental protection department country analyzes test center two Great Britain tests the yellow family property of the chief of the office and eats revealing, legislated strictly, the Great Britain emission of incinerator annual mean two of 2214 sets of domestic rubbish in Japan reduced 99% (71 grams) compared with 1997 in 2003 . China checked to find to 300 tons per day of incinerators of the above handling capacity, the rubbish of the standardard management burnt the factory in 2006, two Great Britain emission is lower than 0.1 to receive gram / one cubic meter of toxic equivalent. Extensive because of two Great Britain sources, including? Help drought red 's silent 's magpie's disease Xi fervent f Great Britain of of fonticuli cranii, two Great Britain exists in water, air and soil of the city extensively, store in two Great Britain on even human blood, the organ. Have data support human body expose, absorb, directly can influence health to two Great Britain in daily life at present.

Two Great Britain of the United Nations discharges the source to investigate expert panel members, research room Deputy Director Zheng MingHui of Ecological Environment Research Center of Chinese Academy of Sciences say, 2.3.7.8 - TCDD is the solid material at room temperature, mainly enter the human body through the food chain. But study to reveal about the toxicity of animals such as the hamster, big mouse,etc., the animal that it is high,etc., the smaller to its influence two Great Britain is. In 2003 - 2006, two total amount in Great Britain that China produced was toxic equivalent of 10.2 kilograms, the ones that came from the rubbish and burnt among them were only about 300 grams. Cancelling the rubbish will not obviously reduce to burn two Great Britain of China.
