Shanghai Songjiang Wastewater Treatment Plant is located in the beautiful and fertile Songjiang District, Shanghai, serving a population of 150,000 people, the service area is mainly the residents of Songjiang District, Shanghai, the discharge of sewage and industrial wastewater, the service area of 300,000 square kilometers, according to the person in charge of the plant, the Shanghai municipal tap water source 80% from the Huangpu River, and the intake is located in the city downstream of the Songjiang Songpu 9.3 kilometers away from the bridge, so the good or bad sewage treatment work will be of particular significance to protect the quality of Huangpu River and the drinking water source in Shanghai. Therefore, the Shanghai Songjiang District of sewage treatment work done well or not will protect the Huangpu River water quality and Shanghai's drinking water source has a particularly important significance, and the Shanghai Songjiang sewage treatment plant to protect the Songjiang District and even the whole of Shanghai's drinking water source of good or bad quality plays a crucial role, therefore, the Shanghai Songjiang sewage treatment plant's operational quality and water quality is good or bad and stable or not appears to be extremely important.
Shanghai Songjiang Wastewater Treatment Plant
Shanghai Songjiang Wastewater Treatment Plant mainly consists of a phase and the second phase of the project, in which a project was put into operation in 1985, the daily capacity of 27,000 tons, the treatment process for the conventional activated sludge method; the second phase of the World Bank's Shanghai Environment Project, the project's total investment of 265 million yuan, of which the World Bank loan of 10 million yuan, the project content, including the expansion of 50,000 tons / day sewage treatment equipment, renovation of a project and urban construction of additional pipe networks and pumping stations, after the transformation of the first phase of the project and the second phase of the treatment process are A/O nitrogen removal process, the transformation and expansion of the Songjiang wastewater treatment plant capacity of 68,000 tons per day.
Songjiang wastewater treatment plant using the A/O method of wastewater treatment process, is currently more advanced in the de-nitrogenation, but also the effect of better wastewater treatment process, the plant's COD intake water quality of nearly 1,000mg / L, but its COD effluent quality of 60mg / L, fully meets the national regulations of the effluent water quality standards, and the effect of denitrogenation is relatively good, due to its advanced wastewater treatment process and technology, which provides a solid backing guarantee for improving the local environmental conditions and preventing water pollution of the Huangpu River.
