Overview
Hunan wastewater treatment plant serves Jiahe County, Chenzhou City, Hunan Province, China, with a population equivalent of 60,000. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Jiahe County, Chenzhou City, in the inland province of Hunan, China. It serves a population of approximately 60,000, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants serving populations around 60,000, secondary 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 is discharged into local waterways that eventually drain into the Xiang River, a major tributary of the Yangtze River. The Xiang River basin supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment at this facility helps protect water quality in the broader Yangtze River ecosystem.
Environmental context
The plant discharges into local streams that flow into the Xiang River, which ultimately joins the Yangtze River before reaching the East China Sea. The Xiang River basin is ecologically significant, supporting freshwater fisheries and providing habitat for migratory fish species. Effective nutrient removal at this plant helps prevent eutrophication in downstream lakes and reservoirs.
