Hunan Wastewater Treatment Plant, Shaoshan City, Hunan Province, China

The Hunan wastewater treatment plant is located in Qingxi Town, Shaoshan City, Xiangtan, Hunan Province, China. It serves a population of approximately 61,000 people, classifying it as a medium-sized agglomeration under typical Chinese municipal wastewater management frameworks. The plant is situated inland, away from coastal areas, and contributes to local water quality management. As a facility in China, the plant operates under the national Water Pollution Prevention and Control Law and relevant discharge standards (e.g., GB 18918-2002). For a population of this scale, secondary treatment with nutrient removal is commonly required to meet effluent standards. Typical Chinese plants of this size employ biological treatment methods such as activated sludge or sequencing batch reactors. The treated effluent is discharged into local water bodies that eventually drain into the Xiang River, a major tributary of the Yangtze River. The Xiang River flows through Hunan Province and supports diverse aquatic life, agricultural irrigation, and downstream communities. Proper treatment at this plant helps protect the Xiang River basin from nutrient pollution and organic contaminants.

The plant discharges into local waterways that flow into the Xiang River, which is part of the larger Yangtze River basin. The Xiang River supports a variety of freshwater species and provides water for agriculture and industry in Hunan Province. Downstream, the Yangtze River estuary is an ecologically important area for migratory fish and birds. Effective wastewater treatment at this plant reduces the risk of eutrophication and protects downstream aquatic habitats.
