Overview
Sichuan wastewater treatment plant serves Pujiang County, Chengdu, Sichuan, China, with a population equivalent of 34,600. It operates under China's national wastewater discharge standards.
The Sichuan wastewater treatment plant is located in Pujiang County, part of Chengdu city in Sichuan Province, China. It serves a population of approximately 34,600, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants serving populations around 34,600, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent likely discharges into a local waterway within the Min River basin, which flows into the Yangtze River and eventually the East China Sea. This downstream connection underscores the plant's role in protecting water quality in a densely populated and agriculturally active region.
Environmental context
The plant discharges into a tributary of the Min River, part of the larger Yangtze River basin. The Yangtze River supports diverse aquatic life and provides water for millions of people. Downstream, the river flows through the Sichuan Basin, an area with intensive agriculture and urban centers, before reaching the East China Sea. Effective treatment is crucial to prevent eutrophication and protect downstream ecosystems.
