Jiangsu Wastewater Treatment Plant, Qingpu District, Shanghai

Jiangsu wastewater treatment plant is located in Baihe Town, Qingpu District, Shanghai, China. It serves a population of approximately 45,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. In China, municipal wastewater treatment plants typically follow the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. Plants serving populations of this scale are generally required to achieve at least secondary treatment, with tertiary treatment increasingly common in sensitive watersheds. The treated effluent is discharged into local water bodies within the Yangtze River Delta region, ultimately flowing into the East China Sea. The plant plays a role in protecting downstream aquatic ecosystems and supporting water quality in a densely populated and industrialized area.

The plant discharges into the local water network within the Yangtze River Delta, a region of significant ecological and economic importance. The treated effluent eventually reaches the East China Sea via the Yangtze River estuary. The area supports diverse aquatic life and is a critical migratory corridor for fish and birds. Nutrient loading from wastewater can impact downstream water quality, making effective treatment essential for maintaining ecological balance.
