Overview
Yunnan wastewater treatment plant serves Shilin Yi Autonomous County in Yunnan, China, with a population of 50,000. The plant operates under China's national wastewater standards.
Yunnan wastewater treatment plant is located in Shilin Yi Autonomous County, Yunnan Province, China. It serves a population of approximately 50,000 people, classifying it as a medium-sized municipal facility within the region's water management infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required to meet environmental standards. The plant's treated effluent is discharged into local water bodies that eventually flow into the broader Yangtze River basin or the Pearl River system, depending on the specific drainage area. These rivers support diverse aquatic ecosystems and provide water for agricultural and industrial use downstream.
Environmental context
The plant discharges into local waterways that are part of the larger river systems in Yunnan, a province known for its biodiversity and as a headwater region for several major Asian rivers. The receiving waters eventually contribute to the Yangtze or Pearl River basins, which support extensive aquatic life and provide water for millions of people. Protecting these waters from nutrient pollution and pathogens is critical for maintaining ecological balance and public health.
