Overview
Sichuan wastewater treatment plant serves 83,300 people in Chengdu, Sichuan Province, China. It operates under China's national wastewater standards for urban agglomerations.
The Sichuan wastewater treatment plant is located in Chengdu, the capital of Sichuan Province in southwestern China. It serves a population of 83,300, placing it in the medium agglomeration category under Chinese wastewater regulations. The plant is situated in the Longquanyi District, an area undergoing rapid urbanization. As a facility serving over 80,000 people, 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 sensitive water bodies. Typical facilities of this scale in Chengdu employ activated sludge processes with biological nitrogen and phosphorus removal. The treated effluent likely discharges into the Jin River or Fu River, tributaries of the Min River, which flows into the Yangtze River basin. The plant plays a critical role in protecting the Yangtze River ecosystem from urban pollution, supporting water quality for downstream communities and aquatic habitats.
Environmental context
The plant's receiving water body is part of the Min River system, a major tributary of the Yangtze River. The Yangtze basin supports diverse aquatic life, including endangered species such as the Chinese sturgeon and finless porpoise. The plant's discharge contributes to the overall nutrient load in the river, and its treatment level is crucial for maintaining downstream water quality in the densely populated Sichuan Basin.
