Yunnan wastewater treatment plant is located in Tonghai County, Yuxi City, Yunnan Province, China, serving an estimated population of 75,000. The facility is part of the municipal wastewater infrastructure for the region, which lies inland in the Yunnan-Guizhou Plateau. As a plant serving a medium-sized agglomeration, it 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 areas. Typical facilities of this scale in China employ activated sludge processes with biological nutrient removal. The treated effluent likely discharges into a local river or water body within the Pearl River basin or a tributary of the Red River system, eventually reaching the South China Sea. The plant plays a key role in protecting downstream aquatic ecosystems and water quality in the region.
Environmental context
