Overview
Hunan wastewater treatment plant serves Suxian District, Chenzhou, Hunan, China, with a population equivalent of 350,000. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Suxian District, Chenzhou City, Hunan Province, China. It serves a population equivalent of 350,000, classifying it as a large-scale municipal facility within the region. As a major treatment plant in inland China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus, with stricter requirements for plants discharging into sensitive water bodies. The plant's treated effluent is discharged into local waterways that ultimately flow into the Xiang River system, a major tributary of the Yangtze River. The Xiang River basin supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment is essential to protect water quality in this densely populated and economically active region.
Environmental context
The plant discharges into the Xiang River basin, which flows into Dongting Lake and then the Yangtze River. The Xiang River is a vital water source for central China, supporting agriculture, industry, and domestic use. The downstream environment includes ecologically sensitive wetlands and fish spawning grounds that depend on good water quality.
