Overview
Hunan wastewater treatment plant serves Shuangfeng County, Loudi City, Hunan Province, China, with a population of 178,300. It operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Yongfeng Subdistrict, Shuangfeng County, Loudi City, Hunan Province, China. It serves a population of approximately 178,300, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local water bodies within the Yangtze River basin. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive receiving waters. Plants of this scale typically employ activated sludge processes with biological nutrient removal to comply with national standards. The plant's discharge ultimately contributes to the Zi River system, a tributary of the Xiang River, which flows into Dongting Lake and then the Yangtze River. This downstream chain supports extensive freshwater ecosystems and provides water for agriculture, industry, and domestic use in Hunan Province. Proper treatment is critical to prevent eutrophication in Dongting Lake and maintain water quality in the Yangtze River basin.
Environmental context
The plant discharges into the Zi River, a tributary of the Xiang River, which flows into Dongting Lake and then the Yangtze River. Dongting Lake is a vital freshwater lake that supports diverse aquatic life and migratory birds. The downstream environment is ecologically sensitive, with wetlands that provide flood regulation and habitat. Effective wastewater treatment is essential to reduce nutrient loads and protect these ecosystems from eutrophication.
