Overview
Hunan wastewater treatment plant serves 64,000 people in Changling, Yueyang, Hunan Province, China. It operates under national environmental regulations for municipal wastewater.
The Hunan wastewater treatment plant is located in Changling Subdistrict, Yunxi District, Yueyang City, Hunan Province, China. It serves a population of approximately 64,000 people, making it a medium-sized agglomeration under Chinese wastewater management standards. The plant is situated in an industrial area near the Changling Petrochemical Complex. As a municipal facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant discharges treated effluent into local waterways that eventually flow into the Yangtze River basin, a major ecological and economic corridor in China. The receiving water body supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment is critical to protect water quality in this densely populated and industrialized region.
Environmental context
The plant's treated effluent enters local streams that drain into the Dongting Lake system, a large freshwater lake connected to the Yangtze River. Dongting Lake is an ecologically sensitive area that supports diverse aquatic life, including migratory birds and fish species. The lake also plays a key role in flood regulation and water supply for the region. Downstream, the Yangtze River flows into the East China Sea, making nutrient and pollutant control essential for coastal water quality.
