Overview
Hunan wastewater treatment plant serves 430,000 people in Lusong District, Zhuzhou, Hunan Province, China. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Jianning Subdistrict, Lusong District, Zhuzhou City, Hunan Province, China. It serves a population of approximately 430,000, classifying it as a large-scale municipal facility within the region. The plant is situated inland, away from coastal areas, and its operations are integral to the local urban wastewater management infrastructure. As a major treatment facility in Hunan Province, the plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national standard sets effluent limits for key parameters such as COD, BOD, ammonia nitrogen, and total phosphorus, with stricter requirements for plants discharging into sensitive water bodies. For a facility of this scale, advanced treatment processes are typically employed to meet these standards. The treated effluent from the plant is discharged into the local water system, which ultimately drains 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 plant helps protect the ecological health of the Xiang River and the broader Yangtze River ecosystem.
Environmental context
The plant discharges into the Xiang River basin, which flows through Hunan Province and joins the Yangtze River at Dongting Lake. The Xiang River supports a variety of freshwater species and is an important water source for surrounding communities. The downstream Dongting Lake is a large floodplain lake that provides critical habitat for migratory birds and aquatic organisms. Effective wastewater treatment at this plant reduces nutrient and pollutant loads, helping to maintain water quality in this ecologically significant watershed.
