Overview
Sichuan wastewater treatment plant serves 36,500 people in Chengdu, Sichuan, China. It operates under China's national wastewater standards for urban agglomerations.
The Sichuan wastewater treatment plant is located in Longtan Subdistrict, Chenghua District, Chengdu, Sichuan Province, China. It serves a population of approximately 36,500, placing it in the small-to-medium agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese wastewater facility, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For agglomerations of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, depending on local environmental requirements. The plant discharges treated effluent into the local water system, which ultimately drains into the Yangtze River basin via the Min River tributary. The Yangtze River supports diverse aquatic ecosystems and provides water for millions downstream, making effective treatment critical for regional water quality and ecological health.
Environmental context
The plant's treated effluent enters the Min River, a major tributary of the Yangtze River, which flows through Sichuan and into the East China Sea. The Yangtze basin is ecologically significant, supporting numerous fish species and providing habitat for migratory birds. Effective nutrient removal at this plant helps reduce eutrophication risks in downstream lakes and coastal waters.
