Overview
Hunan wastewater treatment plant serves approximately 205,200 people in Yuehu Subdistrict, Changsha, Hunan Province, China. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Yuehu Subdistrict (月湖街道), within the Kaifu District of Changsha, Hunan Province, China. The facility serves an estimated population of 205,200, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. Its precise location in the rapidly developing Malanshan Video Cultural and Creative Industrial Park underscores its role in supporting both residential and commercial wastewater needs. As a Chinese municipal wastewater facility serving over 200,000 people, the plant is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets stringent limits on biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients. For plants of this scale, secondary biological treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into a tributary of the Xiang River, which flows northward through Hunan Province and eventually into Dongting Lake, a major freshwater lake connected to the Yangtze River system. This downstream connection to ecologically significant waters necessitates effective treatment to protect aquatic life and water quality in the Xiang River basin and Dongting Lake.
Environmental context
The plant's receiving water body is part of the Xiang River watershed, which drains into Dongting Lake, a large and ecologically important lake in the Yangtze River basin. Dongting Lake supports diverse aquatic life, including migratory fish species, and serves as a critical flood storage area. The Xiang River itself flows through urban and agricultural areas, making nutrient and pollutant control essential to prevent eutrophication and maintain water quality downstream.
