Overview
Jiangsu wastewater treatment plant serves Yixing City, Jiangsu Province, China, with a designed capacity of 1.00 unit. It treats wastewater from a population of 2,000 and discharges into local water bodies.
The Jiangsu wastewater treatment plant is located in Xinjian Town, Yixing City, Wuxi, Jiangsu Province, China. It serves a population of approximately 2,000 people, classifying it as a small-scale municipal facility. The plant is situated inland, more than 50 km from the coast, and its treated effluent is discharged into local rivers that eventually flow into Lake Taihu, a major freshwater lake in the Yangtze River Delta. As a small agglomeration in China, the plant operates under national wastewater discharge standards (GB 18918-2002) which mandate secondary treatment for urban wastewater. Chinese regulations require such facilities to meet Class 1-A or 1-B discharge limits depending on the sensitivity of the receiving water body. The plant's receiving water body is part of the Taihu Lake basin, a region known for its ecological significance and history of eutrophication. The treated effluent contributes to the water quality of local streams that drain into Taihu Lake, which supports fisheries, agriculture, and drinking water supplies for millions. Protecting this watershed is critical for regional environmental health.
Environmental context
The plant discharges into local waterways that are part of the Taihu Lake basin, a large freshwater lake in the Yangtze River Delta. Taihu Lake is ecologically sensitive due to historical algal blooms and nutrient pollution. The downstream environment includes wetlands and rivers that support diverse aquatic life and provide water for irrigation and municipal use. Effective treatment is essential to prevent further degradation of this important water resource.
