Overview
Hunan wastewater treatment plant serves Wuling District, Changde, Hunan, China, with a population of 164,000. It operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Wuling District, Changde City, Hunan Province, China. It serves a population of approximately 164,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the inland region of Hunan, a province known for its dense river networks and subtropical climate. 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 sensitive water bodies. Plants of this scale typically employ biological treatment methods such as activated sludge or A2O processes to achieve compliance. The plant discharges treated effluent into local waterways that ultimately feed into the Dongting Lake system, a major tributary of the Yangtze River. Dongting Lake is a critical ecological zone supporting diverse aquatic life and migratory birds. The plant's performance directly influences water quality in this downstream environment, which is subject to seasonal flooding and agricultural runoff pressures.
Environmental context
The plant's treated effluent flows into the Dongting Lake basin, which connects to the Yangtze River, China's longest waterway. Dongting Lake is a vital freshwater ecosystem that supports fisheries, wetland biodiversity, and flood regulation. The region faces challenges from nutrient pollution and industrial discharges, making the plant's nutrient removal performance crucial for maintaining downstream water quality and ecological balance.
