Overview
Hunan wastewater treatment plant serves Wugang, Shaoyang, Hunan, China, with a population of 151,100. It operates under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Wugang, a county-level city under Shaoyang in Hunan Province, China. It serves a population of approximately 151,100, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes to meet Class 1A or 1B discharge standards. The treated effluent is discharged into local waterways that eventually flow into the Zi River, a tributary of the Yuan River, which joins the Yangtze River system. This contributes to the ecological health of downstream aquatic habitats, including the Dongting Lake watershed, a critical wetland ecosystem supporting diverse fish and bird species.
Environmental context
The plant's discharge enters the Zi River, part of the Yuan River basin, which flows into Dongting Lake and ultimately the Yangtze River. Dongting Lake is a major floodplain lake that supports migratory birds and freshwater fisheries. Effective treatment is essential to prevent nutrient pollution that could harm this ecologically sensitive downstream environment.
