Overview
Yunnan wastewater treatment plant serves the city of Mile (弥阳街道) in Yunnan province, China. It treats wastewater for a population of approximately 132,100.
The Yunnan wastewater treatment plant is located in Mile City (弥阳街道), within the Honghe Hani and Yi Autonomous Prefecture of Yunnan Province, China. The facility serves a population of around 132,100, placing it in the medium-to-large agglomeration category under Chinese wastewater regulations. As a plant of this scale, it is expected to meet national discharge standards under China's Environmental Protection Law and the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). These standards typically require secondary biological treatment with nutrient removal for plants serving over 100,000 people, especially in environmentally sensitive areas. The treated effluent likely discharges into a local waterway that flows into the Nanpan River, a tributary of the Pearl River system. The Pearl River basin supports diverse aquatic ecosystems and provides water for agriculture and industry downstream. Proper treatment is essential to protect water quality in this densely populated and ecologically important region.
Environmental context
The plant's receiving water body is likely a tributary of the Nanpan River, which flows into the Pearl River system and ultimately reaches the South China Sea. The Pearl River basin is a critical water resource for southern China, supporting rich biodiversity and numerous communities. Effective wastewater treatment helps prevent eutrophication and protects downstream aquatic habitats.
