Overview
Hunan wastewater treatment plant serves 216,000 people in Huamen Street, Longhui County, Shaoyang, Hunan, China. It operates under China's national wastewater standards for medium-to-large agglomerations.
The Hunan wastewater treatment plant is located in Huamen Street, Longhui County, Shaoyang City, Hunan Province, China. It serves a population of 216,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The facility is situated inland, approximately 50 km from the coast, and discharges into local water bodies that ultimately drain into the Yangtze River basin. As a plant serving over 200,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for facilities of this scale. Regulatory requirements ensure that treated effluent meets Class 1A or 1B standards depending on the receiving water's sensitivity. The treated wastewater from this plant flows into local rivers and streams within the Zi River system, a tributary of the Yuan River, which joins the Yangtze River near Dongting Lake. The downstream environment supports diverse aquatic life and is important for regional water supply and agriculture. Proper treatment at this plant helps protect water quality in the Yangtze basin, which is ecologically and economically vital for central China.
Environmental context
The plant discharges into the Zi River system, a tributary of the Yuan River, which flows into Dongting Lake and ultimately the Yangtze River. This watershed supports diverse aquatic ecosystems and is a critical water source for agriculture and communities downstream. The region's subtropical climate with seasonal rainfall means that effective nutrient removal is essential to prevent algal blooms in receiving waters.
