Overview
Sichuan wastewater treatment plant serves Guanghan City in Sichuan Province, China, with a population equivalent of 166,300. It operates under China's national wastewater discharge standards.
The Sichuan wastewater treatment plant is located in Guanghan City, Deyang Prefecture, Sichuan Province, China. It serves a population equivalent of approximately 166,300, classifying it as a medium-to-large urban wastewater facility within the region. The plant is situated inland, away from coastal areas, and its operations are integral to the local water management infrastructure. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for such scales. Typical facilities of this size employ activated sludge processes with biological nutrient removal to comply with national standards. The treated effluent is discharged into local water bodies that ultimately flow into the Yangtze River basin. The plant plays a critical role in protecting the water quality of the Tuo River system, a tributary of the Yangtze, and supports the ecological health of downstream aquatic habitats.
Environmental context
The plant discharges into the Tuo River system, a tributary of the Yangtze River, which flows through Sichuan and into the East China Sea. The downstream environment supports diverse aquatic life and is important for regional fisheries and agriculture. Effective treatment is essential to prevent eutrophication and maintain water quality in this densely populated and agriculturally active watershed.
