Overview
Hunan wastewater treatment plant serves Shuangqing District, Shaoyang, Hunan, China, with a population equivalent of 600,000. It operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Shuangqing District, Shaoyang City, Hunan Province, China. It serves a population of approximately 600,000, classifying it as a large-scale municipal facility within the region. As a major treatment plant in Hunan, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for key pollutants. For plants serving over 500,000 people, advanced treatment with nutrient removal is typically required to meet Class 1-A standards, especially in sensitive watersheds. The plant discharges treated effluent into local waterways that eventually flow into the Zi River system, a tributary of the Yangtze River basin. This downstream connection to the Yangtze places importance on effective nutrient and pollutant removal to protect aquatic ecosystems and water quality in the broader region.
Environmental context
The plant's treated effluent enters the Zi River watershed, which flows into Dongting Lake and ultimately the Yangtze River. This downstream chain supports diverse aquatic life and provides water for agriculture and industry. Effective treatment is crucial to prevent eutrophication in Dongting Lake and maintain the ecological health of the Yangtze River basin.
