Overview
Yunnan wastewater treatment plant serves approximately 120,000 people in Xicheng, Qilin District, Qujing City, Yunnan Province, China. The facility operates under national wastewater regulations for medium-sized agglomerations.
The Yunnan wastewater treatment plant is located in Xicheng, Qilin District, Qujing City, Yunnan Province, China. It serves a population of approximately 120,000, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The facility is situated inland, away from coastal areas, and its operations are part of the municipal infrastructure for the region. As a plant serving over 100,000 people, it is expected to meet secondary treatment standards under China's national wastewater discharge regulations (GB 18918-2002). These standards require effective removal of organic matter and suspended solids to protect receiving water bodies. Typical facilities of this scale in China employ activated sludge or similar biological treatment systems. The treated effluent from the plant is discharged into local waterways that ultimately drain into the broader Yangtze River basin or the Pearl River basin, depending on the specific catchment. The region's aquatic ecosystems rely on proper wastewater treatment to maintain water quality and support biodiversity. The plant plays a key role in reducing pollution loads and safeguarding downstream water resources.
Environmental context
The plant discharges into local rivers within the Yunnan-Guizhou Plateau, which eventually flow into larger river systems such as the Yangtze or Pearl River basins. These rivers support diverse aquatic life and are important for regional water supply. Proper treatment is essential to prevent eutrophication and protect downstream ecosystems, including wetlands and reservoirs that provide habitat for migratory birds and fish species.
