Overview
Shanghai wastewater treatment plant serves Jiading District, Shanghai, China, with a population equivalent of 138,000. The facility has a designed capacity of 1.00 unit and is located within 50 km of the coast.
The Shanghai wastewater treatment plant is located in Jiading District, a suburban area of Shanghai, China. It serves a population equivalent of 138,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a facility in China, the plant operates under national wastewater discharge standards, which require secondary treatment for urban wastewater. For agglomerations of this scale, advanced treatment may be mandated in sensitive areas to meet stringent effluent quality standards. Typical Chinese plants employ activated sludge processes with nutrient removal. The plant is situated within 50 km of the coast, indicating potential discharge into the Yangtze River estuary or directly into the East China Sea. The plant's location in the Yangtze Delta region means its effluent ultimately drains into the East China Sea, affecting coastal water quality and marine ecosystems.
Environmental context
The plant is located in the Yangtze River Delta, one of China's most densely populated and industrialized regions. Its treated effluent likely discharges into the Yangtze River or its tributaries, eventually reaching the East China Sea. The downstream environment includes estuarine and coastal habitats that support diverse aquatic life, including fisheries and migratory species. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making advanced treatment important for protecting the marine ecosystem.
Frequently asked questions
The plant is located in Jiading District, Shanghai, China, specifically in the Juyuan New Area (菊园新区).
The plant serves a population equivalent of 138,000, classifying it as a medium-to-large urban wastewater treatment facility.
The plant operates under China's national wastewater discharge standards (GB 18918-2002), which set limits for pollutants. For plants serving over 100,000 people, secondary treatment with nutrient removal is typically required, and in sensitive areas, tertiary treatment may be mandated.
For agglomerations of this scale, Chinese regulations generally require secondary biological treatment, often with additional nutrient removal to meet Class 1A or 1B discharge standards, especially in environmentally sensitive regions like the Yangtze Delta.
