Jiangsu Wastewater Treatment Plant, Wujin District, Changzhou, Jiangsu, China

The Jiangsu wastewater treatment plant is located in Wujin District, Changzhou, within Jiangsu Province, China. It serves a population of approximately 50,000 people, classifying it as a medium-sized municipal facility. The plant is situated in the densely populated Yangtze River Delta region, an area with significant industrial and urban wastewater management needs. As a Chinese wastewater facility, the plant operates under the national standards set by the Ministry of Ecology and Environment, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For a plant serving 50,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B effluent standards, depending on the receiving water body's sensitivity. The designed capacity is reported as 1.00, though the unit is unspecified. The plant's treated effluent is discharged into local waterways that ultimately drain into the Yangtze River and then the East China Sea. The Yangtze River Delta is a critical ecological and economic zone, supporting diverse aquatic life and providing water for agriculture, industry, and drinking. Proper treatment at this facility helps protect downstream water quality and the health of the Yangtze estuary ecosystem.

The plant discharges into the local water network within the Yangtze River basin, which flows eastward into the East China Sea. The Yangtze River Delta is a highly productive estuary supporting fisheries and migratory bird populations. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality in this ecologically sensitive region, which also supplies drinking water to millions downstream.
