Overview
Hunan wastewater treatment plant serves Jishou City, Hunan Province, China, with a population of 132,000. It operates under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Jishou City, within the Xiangxi Tujia and Miao Autonomous Prefecture of Hunan Province, China. Serving a population of 132,000, the plant is a key component of the region's municipal wastewater infrastructure, handling domestic and industrial flows from the urban area. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for larger agglomerations. Typical plants of this scale employ activated sludge processes with biological nutrient removal to comply with national effluent limits. The plant discharges treated effluent into local water bodies within the Yuan River basin, which flows into Dongting Lake and ultimately the Yangtze River. The receiving waters support diverse aquatic life and are important for regional agriculture and fisheries. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant's treated effluent enters local streams within the Yuan River watershed, a tributary of Dongting Lake. Dongting Lake is a large freshwater lake that connects to the Yangtze River, supporting rich biodiversity including migratory birds and fish species. The region's subtropical climate and intensive agriculture make nutrient control essential to avoid algal blooms and maintain water quality for downstream communities.
