Overview
Hunan wastewater treatment plant serves 62,400 people in Baiyun, Chengbu Miao Autonomous County, Shaoyang, Hunan, China. It operates under China's national wastewater standards for medium-sized agglomerations.
The Hunan wastewater treatment plant is located in Baiyun, within Chengbu Miao Autonomous County, Shaoyang City, Hunan Province, China. It serves a population of approximately 62,400, classifying it as a medium-sized municipal facility under Chinese wastewater management frameworks. As a plant serving a medium agglomeration, it is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The facility likely employs conventional biological treatment processes such as activated sludge or sequencing batch reactors, which are typical for plants of this scale in inland regions of Hunan. The plant discharges treated effluent into local water bodies that eventually drain into the Dongting Lake system and the Yangtze River basin. This downstream connection underscores the plant's role in protecting water quality in a region known for its karst landscapes and agricultural activity. Proper treatment helps safeguard aquatic ecosystems and downstream communities.
Environmental context
The plant's treated effluent flows into tributaries of the Zi River or Yuan River, which are part of the larger Dongting Lake watershed. Dongting Lake is a critical flood storage basin and a vital wetland for migratory birds and aquatic biodiversity. The plant's operations contribute to maintaining water quality in this ecologically sensitive region, supporting fisheries and agriculture downstream.
