Overview
Yunnan wastewater treatment plant serves Kunming, Yunnan province, China, with a population equivalent of 123,000. It operates under China's national wastewater discharge standards.
The Yunnan wastewater treatment plant is located in Kunming, the capital of Yunnan province in southwestern China. The facility serves a population equivalent of 123,000, placing it in the medium-to-large agglomeration category for Chinese urban wastewater infrastructure. China's wastewater treatment regulations, governed by the Ministry of Ecology and Environment, require secondary treatment as a minimum for urban plants of this scale. The plant's discharge must comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for COD, BOD, ammonia nitrogen, and other parameters. Advanced treatment may be required if the receiving water body is in a sensitive area. The plant's treated effluent likely discharges into a tributary of the Yangtze River basin, as Kunming lies within the Jinsha River watershed, which flows into the Yangtze and ultimately the East China Sea. The facility plays a key role in protecting local water quality and downstream ecosystems in a region known for its biodiversity and agricultural significance.
Environmental context
The plant is situated in Kunming, Yunnan province, within the Jinsha River watershed, a major tributary of the Yangtze River. Treated effluent eventually reaches the East China Sea. The region supports diverse aquatic life and is an important ecological corridor for migratory fish species. Protecting water quality here helps maintain the ecological health of downstream lakes and rivers, including Dianchi Lake, a large freshwater lake near Kunming that faces eutrophication challenges.
