On the morning of April 4, special garbage transport vehicles transported the municipal solid waste collected in the urban area to the second domestic waste incineration power generation plant of Xuzhou Circular Economy Industrial Park in Dapeng Town, Tongshan District factory. Next to the garbage storage pit, staff use driving grabs to stack the garbage, store it in zones, and ferment it. After that, the garbage that meets the conditions for entering the furnace is put into the furnace for incineration. The steam generated then drives the steam turbine unit to generate electricity. At the same time, after treatment of the flue gas generated by garbage incineration, all types of pollutants meet the national standards and are discharged stably and up to standards. Currently, the first phase of the project processes 2,250 tons of domestic waste per day.
In the Xuzhou Circular Economy Industrial Park, the previous development model of "resources-products-waste" has been broken, and a recycling model of "resources-products-waste-renewable resources" has been formed. In the solid waste treatment area of ??the industrial park, a metabolic production network (waste flow, energy flow, water flow, capital flow and information flow) was constructed according to the three dimensions of inter-project, within the park and park-city system, realizing Small, medium and large cycles of waste treatment. Today, Xuzhou Circular Economy Industrial Park has opened up the "last mile" of coordinating the treatment of various types of municipal solid waste.
As a typical old industrial base and resource-based city, Xuzhou has seen a sharp increase in the production of various urban solid wastes such as domestic waste, construction waste, and municipal sludge with the rapid development of the urban economy. How to "eat up and squeeze out" all kinds of urban garbage? How to create a "waste-free city" through circular economy industry? In recent years, the Xuzhou Municipal Party Committee and Municipal Government, in accordance with the requirements of the central ecological and environmental protection inspection, have made up for the shortcomings and made every effort to build the Xuzhou Circular Economy Industrial Park.
In April 2019, Xuzhou was identified by the Ministry of Ecology and Environment as one of the "11 5" "waste-free city" construction pilots in the country, and it is also the only pilot in Jiangsu Province; in 2020, Xuzhou will be among the national prefecture-level cities. The first "Xuzhou City Industrial Solid Waste Management Regulations" was promulgated, and the "Xuzhou City Domestic Waste Management Regulations" and other laws, regulations and policy documents were promulgated and implemented.
It is understood that the Xuzhou Circular Economy Industrial Park has planned and constructed five functional sectors including solid waste treatment, resource recycling, environmental protection equipment manufacturing, scientific research and education, and new energy. "In the starting area of ??the park, environmental protection projects such as domestic waste incineration power generation, food waste treatment, sewage treatment, hazardous waste disposal, saturated waste activated carbon recycling, construction waste disposal and other environmental projects will be built." The relevant person in charge of the Municipal Urban Management Bureau introduced, "The park construction plan is in accordance with the " "Guiding Opinions of the National Development and Reform Commission on Promoting the Construction of Resource Recycling Bases", based on Xuzhou City's positioning as an important functional area for the safe, concentrated and efficient disposal of urban solid waste, solves the problems of small scale and scattered implementation of environmental protection projects, while achieving industrial aggregation and resource recycling. The goal of utilization. ”
At the beginning of the planning and construction of the Xuzhou Circular Economy Industrial Park, Xuzhou City broke the traditional park model of setting up a “management committee” and explored a trinity of “government economic entities and social intermediary organizations”. (Base) development and construction model, innovatively proposed the "three-coordination" financing model of coordinating construction content, coordinating repayment sources, and coordinating credit enhancement methods, focusing on building an environmental protection design center, an international technology transfer and R&D center, environmental protection new materials and Environmental protection equipment manufacturing industry, etc.
Looking at the "14th Five-Year Plan for the Construction of a "Waste-Free City" in Xuzhou City", the relevant person in charge of the city's national waste-free city headquarters office said that during the "14th Five-Year Plan" period, our city has formulated We have established 49 indicators, 51 tasks and 56 engineering projects, deeply integrated the construction of "waste-free cities" with urban management, unswervingly followed the path of ecological priority and green development, and actively created a pilot demonstration area for the construction of "waste-free cities" , and strive to build a modern city where man and nature live in harmony.
