Overview
Hunan wastewater treatment plant serves Chenzhou, Hunan, China, with a population of 182,000. It operates under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Chenzhou, Hunan Province, China, serving a population of approximately 182,000. The facility is situated in the urban area of Beihu District, along Chenzhou Avenue, and is part of the municipal wastewater infrastructure for the region. As a plant serving a medium-to-large agglomeration, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local water bodies that eventually drain into the Xiang River system, a major tributary of the Yangtze River. The receiving waters support aquatic ecosystems and are used for agricultural and industrial purposes downstream. Proper treatment is essential to protect water quality in the densely populated Hunan region.
Environmental context
The plant's treated effluent flows into local waterways that are part of the Xiang River basin, which ultimately drains into Dongting Lake and then the Yangtze River. This watershed supports diverse aquatic life and provides water for irrigation and industry. The region experiences a subtropical monsoon climate, with seasonal rainfall affecting dilution capacity. Protecting downstream water quality is critical for ecological health and human use.
