Overview
Sichuan wastewater treatment plant serves Guang'an, Sichuan, China, with a population equivalent of 82,700. It operates under China's national wastewater discharge standards.
The Sichuan wastewater treatment plant is located in Guang'an, Sichuan Province, China, serving a population equivalent of approximately 82,700. The facility is situated in Yuechi County, within the broader urban area of Guang'an, and plays a key role in managing municipal wastewater for the region. As a medium-sized agglomeration, 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 plants of this scale. The regulatory framework ensures that treated effluent meets stringent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients before discharge. The plant's treated effluent likely discharges into a local waterway within the Yangtze River basin, ultimately flowing into the East China Sea. The facility helps protect downstream aquatic ecosystems and supports water quality in the region's densely populated and agriculturally active areas.
Environmental context
The plant discharges into a tributary of the Jialing River, a major tributary of the Yangtze River, which flows through Sichuan and Chongqing before joining the Yangtze at Chongqing. The Yangtze River basin supports diverse aquatic life and provides water for millions of people. The plant's operation is critical for reducing nutrient and pollutant loads that could otherwise contribute to eutrophication and ecological degradation in downstream lakes and the East China Sea.
