Daily treatment of 5,100 tons of domestic waste, Asia's largest garbage collaborative incineration disposal monomer project was approved

Cover reporter Chai Fengmu

The "Chengdu Construction Parking Park City Demonstration Zone Action Plan (2021-2025)" proposes that Chengdu will promote the use of resource recycling and realize zero landfill in native domestic garbage. On August 17, the cover reporter learned from Chengdu Environmental Group that the third phase of Chengdu Wanxing Environmental Power Plant project in Chengdu Wanxing Environmental Power Plant has been approved by the Municipal Development and Reform Commission.

After the project is completed and put into operation in the future, 5,100 tons of domestic waste can be treated every day, and nearly 4 million -dollar electricity can be used for nearly 1 million households. At that time, with the existing garbage incineration power generation projects in Chengdu, Chengdu's domestic waste incineration rate will reach 100%, which can basically achieve the target of zero landfill in domestic waste.

How to promote urban domestic garbage reduction, harmlessness, and resourceization? Why does garbage incineration power generation become a hot spot for urban solid waste disposal? What are the advantages of Asia's largest garbage collaborative incineration and disposal of monoso projects? What are the positive impacts of this project on the development of urban green and low -carbon? To this end, the reporter walked into Chengdu Environmental Group Xingrong Renewable Energy Co., Ltd. to fully understand the third phase of the Chengdu Wanxing Environmental Power Plant, and unveiled the "mysterious veil" of waste incineration power generation technology.

After completion, deal with 5100 tons of domestic waste

800 tons of sludge and 800 tons of kitchen waste garbage

In the surrounding mountains, all kinds of environmental protection projects in the Chengdu Changan Pulse Industrial Park are operating in full swing. In the future, the third phase of Chengdu Wanxing Environmental Power Plant will also be completed and put into operation in the park.

According to the "Chengdu Construction and Parking Park Urban Demonstration Zone Action Plan (2021-2025)", Chengdu will accelerate the construction of vein industrial parks.

It is understood that through the construction in recent years, the park has gradually formed an venous industrial cluster that serves the central urban area of ​​Chengdu and radiates surrounding areas and counties.

"The third phase of the Chengdu Wanxing Environmental Power Plant is located in the long -distance vein industrial park, which will help the project and other solid waste treatment projects to form a scale effect and synergy effect, and effectively reduce the cost of domestic waste disposal. Avoiding the problem of neighboring effects that may be caused by the site selection of garbage treatment projects, "said the relevant person in charge of Chengdu Environmental Group Renewable Energy Company.

How large is the specific scale of the project? According to the relevant person in charge of the Chengdu Environmental Group Renewal Energy Company, the project includes domestic waste incineration, sludge dryness coordinated treatment, and kitchen waste treatment facilities. Daily can handle 5100 tons of domestic waste, 800 tons of sludge and 800 tons of kitchen waste, and match 3 rated 55MW condensed steam turbine generators.

After being put into operation, the level of garbage disposal of Chengdu will be improved

Promote the reduction of harmless resourceization of domestic waste

As a hotspot technology of solid waste treatment, countries around the world have successively built waste incineration furnaces. The United States, Japan, Canada, Denmark, Sweden, the Netherlands, Germany, France and other countries generally use incineration methods to deal with garbage. The waste incineration power plant has also become an important way for urban domestic garbage treatment in my country.

"Decreased, harmless, and resource -based is an inevitable choice to efficiently handle urban domestic garbage." The relevant person in charge of the Chengdu Environmental Group Renewable Energy Company said that the first and second phases of Wanxing Environmental Power Plant use "selectivity Non -catalytic reduction method (SNCR)+semi -dry method+dry acid dehydrum+activated carbon adsorption+bag dust collector+selective catalytic reduction method "" The final and second phase of the power plant reached the EU 2000/76/EU standard requirements. "

At present, there are about 19,000 tons of domestic garbage produced by Chengdu every day, which can fill the entire Sichuan Provincial Gymnasium in one day. With the acceleration of urban and rural integration and the improvement of the living standards of the people, the production of domestic waste in Chengdu shows a rapid growth trend. "After the third phase of Wanxing Environmental Power Plant project is completed and put into operation, it will further improve the level of garbage disposal in Chengdu, enhance Chengdu's ability to reduce, resource, and harmless domestic garbage treatment capabilities, and help Chengdu basically achieve all domestic waste incineration power generation. The target of zero landfill.

National Key R & D Plan Project Carbon Reduction Escort

Realize the use of fly ash large -scale resources

During the interview, the reporter learned that Wanxing Environmental Power Plant is closely connected with the national key R & D plan project, which is a vivid case for Chengdu Environmental Group to continue to promote green and low -carbon development.

Last year, Chengdu Environmental Group Renewable Energy Company participated in the national key R & D plan "Key Special Special Special Special for Intergovernmental International Science and Technology Innovation Cooperation "-" Flying ash for high -efficiency and stability/solidification and resource -based technology "based on a mirazine chelating agent" Formally approved. According to the plan, the research results will carry out engineering demonstrations in Wanxing Environmental Power Plant in the future, which will promote the development of waste incineration fly ash and resource -based treatment technology in China, and build a new type of business model of waste incineration fly ash stability and resourceization. , Promoting the construction of circular economy, in the future, it has great promotional value. ‘‘

"Our entire team will use a thorazine chelating agent as a 'medicine to attractive', and the major industrial solid waste into the Chinese patent medicine ', accurate compatibility based on the toxic dialectics, and for the waste incineration fly ash' detoxification and disease '. 'At the same time, let the flying green green building materials. This needs to be meticulous and carefully verified in order to develop a set of environment -friendly and low -cost incineration flying ash disposal and resource -based use of new technologies. " Wang Ying, chief expert of the Chengdu Environmental Group Technology Center (General Work Office) of the R & D project, introduced that the research and development project team has carried out the key influencing factors research and solidification effects of flyy ash efficient and stable effects and the alignment of industrial solid waste collaborative flyyrazine chew The research and development project team has published 2 high -level international papers and applied for a national invention patent. "The reporter learned that the implementation of the research and development project can not only effectively reduce the resource of the resource of the high -temperature building materials in the R & D project. The amount of carbon dioxide generated by the process helps to achieve the "double carbon" goal. At the same time, the fly ash can be filled back to the ground through an ultra -low -cost resource -based method to eliminate its impact on the surface environment, realize the large -scale resource of fly ash use. "Research results will promote the large -scale disposal and utilization of incineration fly ash, which will help improve my country's level and level and level of survey innovation cooperation, and help the construction of 'non -waste cities'." Rao Yi, chairman of Chengdu Environmental Group Renewal Energy Company.
