Jiangsu Wastewater Treatment Plant, Shuyang County, Jiangsu Province

The Jiangsu wastewater treatment plant is located in Shuyang County, Jiangsu Province, China, serving a population equivalent of approximately 68,000. The facility is situated in the urban area of Shuyang, contributing to the region's municipal wastewater management infrastructure. As a medium-sized agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local water bodies that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows into the Yellow Sea, supporting diverse aquatic ecosystems and providing water for agricultural and industrial use downstream. The plant plays a key role in protecting water quality in the densely populated Jiangsu region.

The plant's treated effluent enters local waterways that are part of the Huai River basin, which drains into the Yellow Sea. The Huai River system supports important fisheries and agricultural irrigation in eastern China. The region faces challenges from industrial and agricultural runoff, making effective wastewater treatment critical for maintaining water quality and aquatic habitat in downstream rivers and coastal zones.
