In May this year, Shanghai Jinshan Environmental Renewable Energy Co., Ltd. made remarkable achievements in the construction of a water-saving society in Shanghai, reaching the standard of "Shanghai Water-saving Enterprise".
In the same month, Shanghai Jinshan Environmental Renewable Energy Co., Ltd. won the honor of excellent case (first batch) again for its outstanding performance in the field of pollution reduction and carbon reduction in the collection and selection of typical cases of synergy in pollution reduction and carbon reduction in Shanghai.
In the previous awarding event of Shanghai Safety Culture Construction Demonstration Enterprise, Shanghai Jinshan Environmental Renewable Energy Co., Ltd. won the title of "Shanghai Safety Culture Construction Demonstration Enterprise" in 2023.
Among them, the case of "zero discharge technology of wastewater from domestic garbage burning power plant" is particularly prominent. In this case, the water balance and production process of Jinshan domestic waste incineration power plant in the actual production process were first investigated, the wastewater drainage point and water use point were summarized, and then the water quality and quantity of the water use point and the drainage point were compared, and the water use point and drainage point were matched, and the medium gradient utilization plan was formulated to carry out gradient utilization of wastewater.
By optimizing the sewage treatment process and developing the process of efficient wastewater treatment + cascade utilization of reclaimed water, the production water consumption of domestic waste incineration power plants is greatly reduced, and the water and sewage costs of domestic waste incineration power plants are reduced, which not only improves the reuse rate of sewage at the production site, but also achieves zero sewage discharge.
According to statistics, Shanghai Jinshan Environmental Renewable Energy Co., Ltd. can reduce the amount of industrial tap water by 300t/d and save about 400t/d of river water intake after optimizing the process through multi-level and multi-field synergistic measures for pollution reduction and carbon reduction, which is expected to bring direct economic benefits of 1.9 million yuan/year, set a green and low-carbon benchmark for sewage treatment, and make positive contributions to the improvement and sustainable development of the ecological environment in Jinshan District and surrounding areas.
It is understood that Shanghai Jinshan Environmental Renewable Energy Co., Ltd. is a wholly-owned subsidiary of Shanghai Environment Group Co., Ltd. and is a government concession project. It undertook the dry waste disposal service in Jinshan District and the combustible general industrial solid waste disposal service in Jinshan District, Qingpu District and Songjiang District. The domestic waste disposal in Jinshan District has been upgraded from the traditional landfill mode to the zero landfill, recycling, reduction, and harmless incineration treatment mode, which has achieved leapfrog development and effectively improved the urban and rural living environment.
At present, the plant has a total of three 500T incineration lines, two 15MW condensing steam turbine generator sets, a daily household waste processing capacity of 1,500T, an annual domestic waste processing capacity of about 500,000 tons, an annual power generation of about 230 million kWh, and an on-grid power generation of about 180 million kWh.
