Overview
Sichuan wastewater treatment plant serves 67,200 people in Pidu District, Chengdu, Sichuan, China. It operates under China's national wastewater standards for urban agglomerations.
The Sichuan wastewater treatment plant is located in Pidu District (Pitong Subdistrict), Chengdu, Sichuan Province, China. It serves a population of approximately 67,200, classifying it as a medium-sized urban agglomeration under Chinese municipal wastewater regulations. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 50,000 people. Regulatory requirements for this population tier typically involve biological treatment with nitrogen and phosphorus removal. The plant discharges treated effluent into local waterways within the Yangtze River basin, ultimately draining into the East China Sea. Its location in the Chengdu Plain, a densely populated agricultural and industrial region, underscores its role in protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant's treated effluent enters the Min River system, a major tributary of the Yangtze River, which flows through Sichuan and eventually reaches the East China Sea. The downstream environment supports diverse aquatic life and provides water for irrigation and urban use. The Chengdu Plain is ecologically sensitive due to intensive agriculture and rapid urbanization, making effective wastewater treatment critical for preventing eutrophication and protecting biodiversity.
