Overview
Hunan wastewater treatment plant serves 480,000 people in Yuetang District, Xiangtan, Hunan Province, China. It discharges treated effluent into local waterways within the Xiang River basin.
The Hunan wastewater treatment plant is located in Yuetang District, Xiangtan City, Hunan Province, China. It serves a population of approximately 480,000, classifying it as a large agglomeration under Chinese wastewater management standards. The facility is situated in an inland urban area, supporting the municipal infrastructure of Xiangtan. As a large-scale plant, it is expected to meet secondary or advanced treatment standards under China's national wastewater discharge regulations, which align with the Water Pollution Prevention and Control Law. Facilities of this size typically employ biological treatment methods such as activated sludge to reduce organic pollutants and nutrients before discharge. The treated effluent from the plant is released into local water bodies that ultimately flow into the Xiang River, a major tributary of the Yangtze River. The Xiang River basin supports diverse aquatic ecosystems and provides water for agricultural and industrial use downstream. Proper treatment at this plant helps protect water quality in the Xiang River and the broader Yangtze River system.
Environmental context
The plant discharges into the Xiang River basin, which flows into Dongting Lake and then the Yangtze River. The downstream environment includes ecologically sensitive wetlands and floodplains that support migratory birds and aquatic species. Nutrient removal at this plant is critical to prevent eutrophication in Dongting Lake, a key freshwater resource in central China.
Frequently asked questions
The plant is located in Yuetang District, Xiangtan City, Hunan Province, China, specifically in the Shejiancun and Dishuibu subdistricts.
The treated effluent is discharged into local waterways within the Xiang River basin, which flows into Dongting Lake and eventually the Yangtze River.
The plant helps protect the Xiang River and its tributaries, which are part of the larger Yangtze River system, by reducing pollutant loads from municipal wastewater.
The plant operates under China's Water Pollution Prevention and Control Law, which sets discharge standards for pollutants. Large agglomerations like this one are typically required to achieve secondary treatment or higher to meet environmental quality standards.
Plants of this scale in China commonly use biological treatment processes such as activated sludge or oxidation ditches, often with nutrient removal to meet stringent discharge limits for nitrogen and phosphorus.
