The Sichuan wastewater treatment plant is located in Shunqing District, Nanchong, within Sichuan Province, China. It serves a population of approximately 77,000 residents, placing it in the medium-sized agglomeration category for the region. As a municipal facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into the Jialing River, a major tributary of the Yangtze River, which flows through Nanchong. The Jialing River supports diverse aquatic life and is an important water source for downstream communities. Proper treatment helps protect water quality in the Yangtze River basin, one of China's most ecologically and economically significant watersheds.
Environmental context
The plant's treated effluent likely enters the Jialing River, which flows southward through Nanchong before joining the Yangtze River at Chongqing. The Jialing River supports a variety of fish species and provides water for irrigation and drinking water intakes downstream. The Yangtze River basin is a critical ecological zone, home to endangered species such as the Chinese sturgeon and finless porpoise, making effective wastewater treatment essential for maintaining water quality and biodiversity.
