Overview
Jiangsu wastewater treatment plant serves Kunshan, Jiangsu, China, with a designed capacity of 1.00 (units unspecified) and a population equivalent of 420,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Kunshan, a city in Jiangsu Province, China. The facility serves a population equivalent of 420,000, placing it in the large agglomeration category. Its designed capacity is 1. The plant is situated inland, more than 50 km from the coast, and discharges into local water bodies within the Yangtze River Delta region. As a large-scale municipal plant in China, the facility is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for COD, BOD, ammonia nitrogen, total phosphorus, and other parameters. Plants of this size typically employ secondary biological treatment (e. g. , activated sludge) followed by disinfection, with some also incorporating tertiary treatment for nutrient removal. The regulatory framework requires compliance with Class 1A or 1B standards depending on the receiving water's sensitivity. The treated effluent is discharged into local rivers that ultimately drain into the Yangtze River and the East China Sea. The Yangtze River Delta is a densely populated and economically vital region, where wastewater treatment plays a critical role in protecting downstream aquatic ecosystems and maintaining water quality for drinking, agriculture, and industry.
Environmental context
The plant's effluent flows into the local river network within the Yangtze River basin, which discharges into the East China Sea. This region supports diverse aquatic life and is an important migratory corridor for fish species. The Yangtze River Delta faces pressures from urbanization and industrial activity, making effective wastewater treatment essential for preventing eutrophication and safeguarding downstream habitats.
