Overview
Hunan wastewater treatment plant serves Hengyang, Hunan, China, with a population of 820,000. It operates under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Hengyang, Hunan Province, China, serving a population of approximately 820,000. The plant is situated in the Xiang River basin, a major tributary of the Yangtze River, and plays a key role in managing municipal wastewater from the urban area of Hengyang. As a large-scale facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. It likely employs conventional activated sludge or similar biological treatment to comply with national standards. The treated effluent is discharged into local waterways that flow into the Xiang River, which eventually reaches Dongting Lake and the Yangtze River. This downstream connection underscores the plant's importance in protecting water quality in one of China's most densely populated and agriculturally productive regions.
Environmental context
The plant discharges into the Xiang River system, a major tributary of the Yangtze River. The Xiang River flows through Hunan into Dongting Lake, a large freshwater lake that supports diverse aquatic life and is an important ecological zone. The region faces challenges from industrial and agricultural runoff, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
