Overview
Yunnan wastewater treatment plant serves Jiangchuan District, Yuxi City, Yunnan, China, with a population equivalent of 112,000. The plant discharges into local water bodies within the broader Yangtze River basin.
Yunnan wastewater treatment plant is located in Jiangchuan District, Yuxi City, Yunnan Province, China. It serves a population equivalent of 112,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, approximately 50 km from the coast, and its operations are part of the municipal infrastructure for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to meet Class 1-A or 1-B effluent limits, which mandate secondary treatment with nutrient removal. The plant is expected to comply with these regulatory requirements to protect receiving water bodies. The plant's treated effluent likely discharges into local rivers or lakes within the Yunnan-Guizhou Plateau watershed, eventually contributing to the Yangtze River basin. The region is ecologically significant, supporting diverse aquatic life and providing water resources for agriculture and urban use. Proper treatment is essential to prevent eutrophication and maintain water quality in downstream ecosystems.
Environmental context
The plant discharges into local water bodies within the Yunnan-Guizhou Plateau, which drains into the Yangtze River basin via tributaries such as the Jinsha River. The receiving waters support diverse aquatic ecosystems and are important for regional agriculture and drinking water supplies. The plateau's karst topography makes groundwater particularly vulnerable to contamination, emphasizing the need for effective nutrient removal to prevent algal blooms and protect downstream biodiversity.
