Overview
Yunnan wastewater treatment plant serves 42,500 people in Chuxiong, Yunnan Province, China. It operates under national wastewater standards for inland treatment facilities.
The Yunnan wastewater treatment plant is located in Chuxiong, Yunnan Province, China, serving a population of approximately 42,500. The facility is situated in the Yi Hai Street area of Chuxiong, within the Chuxiong Yi Autonomous Prefecture, and is part of the regional wastewater infrastructure for the city. As a medium-sized agglomeration, the plant is expected to meet China's national discharge standards for urban wastewater treatment, which typically require secondary treatment or higher. Facilities of this scale in China generally employ biological treatment processes such as activated sludge to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant discharges treated effluent into local water bodies that ultimately drain into the Yangtze River basin via the Jinsha River system. This inland location means the plant's discharge affects freshwater ecosystems, requiring careful management to protect downstream water quality and aquatic life.
Environmental context
The plant's treated effluent flows into local streams that are part of the Jinsha River watershed, a major tributary of the upper Yangtze River. This region supports diverse freshwater habitats and is important for migratory fish species. The Yangtze River basin is ecologically significant, hosting numerous endemic species and providing water resources for millions of people downstream.
