Overview
Hunan wastewater treatment plant serves Jishou City in Hunan Province, China, with a population of 257,600. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Jishou City, within the Xiangxi Tujia and Miao Autonomous Prefecture of Hunan Province, China. It serves a population of approximately 257,600, classifying it as a large-scale municipal facility under Chinese wastewater management frameworks. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate specific treatment levels based on receiving water sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially when discharging into environmentally sensitive waters. The plant's treated effluent likely discharges into a local river within the Dongting Lake basin, which ultimately flows into the Yangtze River and the East China Sea. The region's aquatic ecosystems depend on effective nutrient and pollutant removal to prevent eutrophication and protect downstream biodiversity.
Environmental context
The plant is situated inland, over 50 km from the coast, and its discharge likely enters a tributary of the Yuan River, part of the Dongting Lake system. Dongting Lake is a critical flood storage basin and wetland that supports diverse fish and bird species. Downstream, the Yangtze River carries water to the East China Sea, making pollutant control essential for both local and regional ecological health.
