Overview
Yunnan wastewater treatment plant serves Shuangbai County in Yunnan, China, with a population of 86,000. It is located inland, discharging into local water bodies.
The Yunnan wastewater treatment plant is located in Shuangbai County, part of the Chuxiong Yi Autonomous Prefecture in Yunnan Province, China. It serves a population of approximately 86,000 people, placing it in the medium agglomeration category. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater management infrastructure. As a facility serving a medium-sized population, the plant is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law. Typical plants of this scale employ secondary biological treatment to reduce organic pollutants and suspended solids. The regulatory framework in China mandates compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for key parameters. The plant discharges treated effluent into local rivers that eventually flow into the broader Yangtze River basin, which is ecologically significant for its biodiversity and water supply. The downstream environment supports aquatic life and agricultural activities, making effective treatment crucial for maintaining water quality and ecosystem health.
Environmental context
The plant's treated effluent enters local waterways that drain into the Yangtze River basin, one of China's most important river systems. The Yangtze supports diverse aquatic species and provides water for millions of people. Effective wastewater treatment is essential to prevent nutrient pollution and protect downstream ecosystems, including wetlands and fisheries.
