Overview
Sichuan wastewater treatment plant serves Shangxi Subdistrict in Guangyuan, Sichuan, China, with a population equivalent of 367,700. It operates under China's national wastewater discharge standards.
The Sichuan wastewater treatment plant is located in Shangxi Subdistrict, Lizhou District, Guangyuan City, Sichuan Province, China. It serves a population of approximately 367,700, classifying it as a large-scale municipal treatment facility under Chinese regulatory frameworks. As a large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for facilities serving over 100,000 people. Regulatory requirements ensure a minimum level of treatment for environmental protection. The plant discharges treated effluent into local water bodies within the Jialing River basin, which flows into the Yangtze River. The downstream environment supports diverse aquatic life and provides water for agricultural and industrial use, making effective treatment crucial for maintaining water quality in the region.
Environmental context
The plant's effluent enters the Jialing River system, a major tributary of the Yangtze River. The Jialing River flows through mountainous terrain in Sichuan, supporting freshwater ecosystems and providing water for irrigation and urban use. Downstream, the Yangtze River is a critical ecological corridor for numerous fish species, including the endangered Chinese sturgeon. Effective wastewater treatment is essential to prevent eutrophication and protect biodiversity in this densely populated and ecologically significant watershed.
