Overview
Hunan wastewater treatment plant serves Xiangxiang City in Hunan Province, China, with a population equivalent of 200,000. The facility discharges into local waterways under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Xiangxiang City, within the Xiangtan prefecture of Hunan Province, China. It serves a population of approximately 200,000 people, classifying it as a large-scale municipal facility under Chinese environmental regulations. China's wastewater treatment standards, governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary treatment as a baseline for plants of this size. Typical facilities serving this population employ activated sludge processes with nutrient removal to meet Class 1A or 1B effluent standards. The treated effluent is discharged into the local river system, which ultimately flows into the Xiang River, a major tributary of the Yangtze River. The Xiang River supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment at this plant helps protect water quality in the Xiang River basin and the broader Yangtze ecosystem.
Environmental context
The plant discharges into the Xiang River basin, which flows into the Yangtze River and eventually the East China Sea. The Xiang River supports a variety of fish species and is an important water source for communities and agriculture in Hunan Province. Effective treatment reduces nutrient and pollutant loads, helping to prevent eutrophication and maintain ecological balance in downstream waters.
