Overview
Hunan wastewater treatment plant serves Yuhua District, Changsha, China, with a population of 474,700. It operates under China's national wastewater standards for large urban agglomerations.
The Hunan wastewater treatment plant is located in Yuhua District, Changsha, Hunan Province, China. It serves a population of approximately 474,700, classifying it as a large urban agglomeration under Chinese wastewater regulations. The plant is situated in the Lixtuo subdistrict, within the densely populated Changsha metropolitan area. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Facilities of this scale typically employ activated sludge processes with biological nutrient removal to comply with national effluent limits. The plant discharges treated wastewater into the local water system, which ultimately drains into the Xiang River, a major tributary of the Yangtze River. The Xiang River flows through Hunan Province and into Dongting Lake, a large freshwater lake connected to the Yangtze. This downstream ecosystem supports diverse aquatic life and provides water for agriculture and industry in the region.
Environmental context
The plant's treated effluent enters the local drainage network, which flows into the Xiang River, a key tributary of the Yangtze River. The Xiang River passes through Changsha and other urban centers before reaching Dongting Lake, a vital wetland that regulates floodwaters and supports migratory birds and fish. The plant's discharge quality is critical for maintaining the ecological health of these downstream water bodies, particularly given the high population density and industrial activity in the region.
