Overview
Shanghai wastewater treatment plant serves Pudong New Area, Shanghai, China, with a designed capacity of 1.00 unit and a population equivalent of 697,000. It is located within 50 km of the coast, discharging into the East China Sea.
The Shanghai wastewater treatment plant is situated in the Laogang solid waste comprehensive utilization base, Laogang Town, Pudong New Area, Shanghai, China. It serves a population equivalent of approximately 697,000, making it a large-scale municipal facility within one of the world's most populous urban regions. As a major agglomeration in China, the plant operates under national wastewater discharge standards that typically require secondary treatment or higher for such population scales. Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for organic matter, nutrients, and pathogens. The plant's treated effluent ultimately reaches the East China Sea via the Huangpu River and Yangtze River estuary. This coastal discharge zone supports diverse marine ecosystems, including fisheries and migratory bird habitats, making effective nutrient removal critical to prevent eutrophication in the receiving coastal waters.
Environmental context
The plant discharges into the East China Sea via the Yangtze River estuary, a major marine ecosystem supporting rich biodiversity and commercial fisheries. The coastal waters are influenced by tidal flows and seasonal freshwater input, requiring careful management of nutrient loads to avoid algal blooms and hypoxia. The area is ecologically sensitive due to its role as a spawning and nursery ground for many fish species.
