Jiangsu Wastewater Treatment Plant, Qidong, Jiangsu Province, China

The Jiangsu wastewater treatment plant is located in Jinhai Town, Qidong City, Nantong, Jiangsu Province, China. It serves a population equivalent of 110,000, classifying it as a large agglomeration under Chinese wastewater regulations. 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 plants serving over 100,000 people, advanced treatment may be mandated in sensitive areas to meet stricter effluent limits. The plant discharges into local water bodies that ultimately flow into the East China Sea. The region's coastal environment supports diverse aquatic life and is important for fisheries. Proper treatment is essential to protect downstream ecosystems and coastal water quality.

The plant is situated in the Yangtze River Delta region, with its treated effluent likely entering local rivers that drain into the East China Sea. This coastal area supports important fisheries and migratory bird habitats. The proximity to the coast (within 50 km) means that nutrient and pollutant loads can directly impact marine ecosystems, including potential eutrophication risks. The local watershed is part of a densely populated and industrialized region, making effective wastewater treatment critical for environmental health.
