Overview
The Jiangsu wastewater treatment plant serves 240,000 people in Zhangjiagang, Jiangsu Province, China. It is located within 50 km of the coast and discharges into the Yangtze River basin.
The Jiangsu wastewater treatment plant is located in Zhangjiagang, a city in Jiangsu Province, China, within the Yangtze River Delta region. It serves a population of 240,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated in an industrial and urban area near the Yangtze River. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary treatment as a baseline, with stricter limits for sensitive water bodies. For a plant of this scale, advanced treatment is often expected to protect downstream water quality. The designed capacity is 1.00 (likely in 10,000 m³/day), indicating a substantial facility. The plant's treated effluent ultimately flows into the Yangtze River, which is the longest river in Asia and a critical water resource for millions. The Yangtze River estuary and the East China Sea are the final receiving waters. The plant plays a key role in reducing nutrient and pollutant loads to this ecologically and economically vital river system.
Environmental context
The plant discharges into the Yangtze River basin, which flows into the East China Sea. The Yangtze River estuary supports diverse aquatic life, including migratory fish species, and is an important ecological corridor. Downstream waters are influenced by tidal flows and industrial activity, making nutrient and pollutant management critical for coastal water quality.
Frequently asked questions
