Overview
Hunan wastewater treatment plant serves Guidong County in Hunan Province, China, with a population of 42,600. The facility operates under China's national wastewater discharge standards.
Hunan wastewater treatment plant is located in Guidong County, Chenzhou City, Hunan Province, China. The facility serves a population of approximately 42,600, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese municipal plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants serving populations of this scale, secondary biological treatment is typically required, with nutrient removal in sensitive watersheds. The plant discharges into local waterways within the Xiang River basin, which ultimately flows into Dongting Lake and then the Yangtze River. This watershed supports diverse aquatic life and provides water for agricultural and municipal use downstream. Proper treatment is essential to protect water quality in this ecologically significant region.
Environmental context
The plant discharges into the Xiang River basin, a tributary of the Yangtze River system via Dongting Lake. This watershed supports diverse aquatic ecosystems and provides drinking water for millions downstream. The region's subtropical climate with seasonal rainfall means treatment must handle variable flows to prevent pollution during wet weather events.
