Overview
Sichuan wastewater treatment plant serves Pengshan District, Meishan, Sichuan, China, with a population of 56,500. It operates under China's national wastewater standards.
The Sichuan wastewater treatment plant is located in Pengshan District, Meishan City, Sichuan Province, China. It serves a population of approximately 56,500 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water body sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially when discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local river 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 one of China's most important watersheds, supporting aquatic ecosystems and downstream water uses.
Environmental context
The plant is situated in the Min River basin, a tributary of the Yangtze River. The Yangtze River system supports diverse aquatic life and provides water for millions of people. Discharges from the plant must meet strict standards to prevent eutrophication and protect the ecological health of downstream rivers and lakes.
