Overview
Hunan wastewater treatment plant serves Dingcheng District, Changde, Hunan, China. It treats wastewater from approximately 128,000 people, operating under China's national discharge standards.
The Hunan wastewater treatment plant is located in Yuxia Street, Dingcheng District, Changde City, Hunan Province, China. It serves a population of approximately 128,000, making it a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local waterways that ultimately feed into 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 Plants (GB 18918-2002), which mandates secondary treatment as a minimum. For larger plants in sensitive watersheds, advanced treatment may be required to reduce nitrogen and phosphorus loads. The plant's operational details, including specific treatment processes and capacity, are not publicly available, but its scale suggests it plays a key role in regional water quality management. The plant's receiving water body is part of the Dongting Lake system, a major tributary of the Yangtze River. Dongting Lake is ecologically significant, supporting diverse aquatic life and serving as a critical flood storage area. The plant's operations help protect downstream water quality in the Yangtze River, which is vital for drinking water, agriculture, and fisheries across central and eastern China.
Environmental context
The plant discharges into local waterways that flow into Dongting Lake, the second-largest freshwater lake in China, which then drains into the Yangtze River. Dongting Lake is an ecologically sensitive area that supports migratory birds and fish species. The Yangtze River downstream is a major source of drinking water and irrigation for millions of people, making effective wastewater treatment crucial for preventing eutrophication and maintaining aquatic biodiversity.
