Overview
Hunan wastewater treatment plant serves Changhong Street, Qiyang, Yongzhou, Hunan, China, with a population equivalent of 254,800. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Changhong Street, Qiyang, Yongzhou, Hunan Province, China. It serves a population of approximately 254,800, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated near the G322 highway and the Wuxi hydropower station, within the Xiang River basin. As a facility of this scale in China, the plant is expected to meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical plants serving this population range from 50,000 to 100,000 m³/day. The treatment process likely includes biological treatment and disinfection to comply with national effluent limits. The plant discharges treated effluent into the Xiang River, a major tributary of the Yangtze River. The Xiang River flows through Hunan and into Dongting Lake, a large freshwater lake that supports diverse aquatic life and is an important ecological area. The plant's operations contribute to protecting downstream water quality and the ecological health of the Yangtze River basin.
Environmental context
The Hunan plant discharges into the Xiang River, which flows into Dongting Lake and ultimately the Yangtze River. Dongting Lake is a critical wetland that supports migratory birds and fish species. The plant's effluent must meet strict standards to prevent eutrophication and protect aquatic biodiversity in this ecologically sensitive region.
