Overview
Sichuan wastewater treatment plant serves Shehong City, Sichuan, China, with a population of 199,600. It operates under China's national wastewater standards, ensuring treated effluent meets regulatory requirements.
The Sichuan wastewater treatment plant is located in Shehong City, Sichuan Province, China, along Binjiang Road in the Taihe subdistrict. It serves a population of approximately 199,600, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the upper reaches of the Fujiang River basin, a tributary of the Jialing River, which ultimately flows into the Yangtze River. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater plants serving populations above 100,000. The facility is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and phosphorus. Given the population served, the plant likely incorporates biological treatment processes to meet these standards. The treated effluent from the plant is discharged into the local water system, eventually reaching the Fujiang River. This river flows through the Sichuan Basin and joins the Jialing River, a major tributary of the Yangtze River. The plant plays a critical role in protecting the water quality of the Fujiang River and downstream ecosystems, supporting both agricultural and urban water uses in the region.
Environmental context
The plant discharges into the Fujiang River, a tributary of the Jialing River, which flows into the Yangtze River. The Fujiang River supports diverse aquatic life and is an important water source for irrigation and industry in the Sichuan Basin. The plant's operations help reduce nutrient and organic pollutant loads, protecting downstream water quality and ecological health in the Yangtze River system.
