Suzhou Industrial Park, the second sewage treatment plant construction goal for the construction of "municipal gold cup demonstration project", the operation of the target for "the country's top ten sewage treatment plants. The project has adopted a large number of energy-saving and consumption reduction measures, mainly: 1, the introduction and use of the United States Biochemical Technology Corporation advanced sewage treatment control and optimization system - biological process intelligence optimization system, the system can significantly improve and enhance the sewage treatment facilities and sewage treatment facilities and sewage treatment plant operation stability and reliability, reduce aeration energy and operating costs, saving electricity; 2, the introduction and use of the United States Biochemical Technology Corporation advanced sewage treatment control and optimization systems 2, the implementation of 20,000 tons / day water reuse project, water quality indicators to meet the recycled cooling water indicators, for the Dongwu Thermal Power Plant to provide cooling recycling water, while the sludge drying project for the Sino-French environment to provide cooling water, but also for the plant's own use to provide water for flushing, landscaping water, plant bathroom water and dissolved medicine water. 3、Sludge produced by the plant and the first sewage treatment plant are all dried and treated by Sino-French Environment, and the treated sludge is incinerated by Dongwu Thermal Power Plant, thus forming a closed circular economy industry chain with water and sludge as media. 4、Make full use of the idle land in the protection range of high-pressure corridor in the plant, and build an ecological wetland covering an area of 15 acres along the terrain, which is used to further optimize the quality of effluent water while beautifying the environment of the plant. 5、In terms of building energy saving, the roof adopts natural lighting, the outer wall adopts broken bridge hollow glass, and the street light adopts solar energy lighting. 6、Investment of 20 million yuan to synchronize the completion of water, sewage water quality testing center, and plans to pass the national laboratory certification next year, for the park's tap water, sewage, stable standards to provide timely support. Suzhou Industrial Park, the second phase of the sewage treatment plant project was completed and put into trial operation, will be more prominent in the park's environmental advantages, the Suzhou Industrial Park and Suzhou City's national economy to provide a strong guarantee of sustainable development.
