Overview
The Yunnan wastewater treatment plant serves 610,000 people in Xishan District, Kunming, China. It operates under China's national wastewater standards, discharging into the Dianchi Lake basin.
The Yunnan wastewater treatment plant is located in Xishan District, Kunming, Yunnan Province, China, serving a population of 610,000. The plant is part of the municipal infrastructure for the city of Kunming, situated in the Dianchi Lake watershed. As a large-scale facility serving over 600,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Typical facilities of this scale employ activated sludge processes with biological nutrient removal. The treated effluent likely discharges into the Dianchi Lake basin, a large freshwater lake that ultimately drains into the Yangtze River via the Pudu River. Dianchi Lake is ecologically significant as a major water body in Yunnan, supporting diverse aquatic life and providing water for agriculture and industry. The plant plays a crucial role in protecting the lake from eutrophication and maintaining water quality.
Environmental context
The plant discharges into the Dianchi Lake watershed, which flows into the Pudu River and eventually the Yangtze River. Dianchi Lake is a large, shallow lake that has experienced eutrophication due to nutrient loading. The plant's advanced treatment helps reduce phosphorus and nitrogen inputs, protecting the lake's ecosystem and downstream water quality.
