Overview
Sichuan wastewater treatment plant serves 122,000 people in Wuxingjie Street, Zigong, Sichuan, China. It operates under China's national wastewater standards, discharging treated effluent into local waterways.
The Sichuan wastewater treatment plant is located in Wuxingjie Street, a district of Zigong City in Sichuan Province, China. Serving a population of 122,000, the facility is part of the municipal wastewater infrastructure for this inland urban area in the Sichuan Basin. As a plant serving over 100,000 people, it falls under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for such agglomerations. The regulatory framework requires robust treatment to protect receiving waters. The plant discharges into the local river system, which ultimately drains into the Yangtze River basin. The receiving water body supports aquatic life and is used for downstream irrigation and industrial purposes. Effective treatment is critical to prevent eutrophication and maintain water quality in this densely populated region.
Environmental context
The plant's treated effluent enters the local tributary network of the Tuo River, a major tributary of the Yangtze River. The downstream environment includes agricultural areas and urban centers that rely on the river for water supply. Protecting this watershed from nutrient pollution is essential to prevent algal blooms and maintain ecological balance in the Yangtze basin.
