Jiangsu Wastewater Treatment Plant, Pei County, Xuzhou, China

The Jiangsu wastewater treatment plant is located in Pei County, Xuzhou, within Jiangsu Province, China. It serves a population equivalent of 150,000, classifying it as a large agglomeration under Chinese regulatory frameworks. The plant is situated inland, approximately 50 km from the coast, and its treated effluent likely discharges into local rivers that flow toward the Yellow Sea. As a facility of this scale in China, the plant is expected to meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. The plant's size suggests it likely incorporates biological treatment with nitrogen and phosphorus removal to comply with national standards. Given its location in the Huai River basin, treated wastewater likely enters local waterways that drain into the Yellow Sea. This discharge supports downstream aquatic ecosystems and agricultural water reuse, though it also requires careful management to prevent eutrophication in receiving waters.

The plant is located in the Huai River basin, a major watershed in eastern China that drains into the Yellow Sea. The region supports intensive agriculture and dense urban populations, making water quality management critical. Downstream ecosystems include freshwater wetlands and coastal habitats that rely on balanced nutrient levels. The plant's discharge contributes to the overall water quality of the basin, which is subject to seasonal variations and industrial pressures.
