Overview
Hunan wastewater treatment plant serves Yunhu Subdistrict, Linxiang, Yueyang, Hunan, China. It treats wastewater for approximately 236,000 people, operating under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Yunhu Subdistrict, Linxiang City, Yueyang, Hunan Province, China. It serves a population of approximately 236,000, making it a medium-to-large agglomeration under Chinese classification. The plant is situated inland, away from the coast, and its operations are part of the municipal infrastructure for the region. As a facility serving over 100,000 people, the plant 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 such scales. The plant likely employs biological treatment processes common in Chinese facilities, such as activated sludge or A2O, to achieve compliance with effluent standards. The treated effluent is discharged into local water bodies that ultimately drain into the Yangtze River basin via the Xiang River system. The plant plays a crucial role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Hunan region, which is known for its extensive river networks and agricultural activity.
Environmental context
The plant discharges into local waterways that flow into the Xiang River, a major tributary of the Yangtze River. The Xiang River supports diverse aquatic life and provides water for irrigation and drinking downstream. The region's watershed is ecologically sensitive due to intensive agriculture and urban development, making effective wastewater treatment essential for maintaining water quality and preventing eutrophication in downstream lakes and rivers.
