Overview
Chongqing wastewater treatment plant serves 1,450,000 people in Liangjiang New Area, Chongqing, China. It operates under China's national wastewater standards, discharging treated effluent into the Yangtze River basin.
The Chongqing wastewater treatment plant is a major municipal facility located in Liangjiang New Area, Chongqing, China. Serving a population of 1,450,000, it is classified as a large agglomeration under Chinese wastewater regulations, which require advanced treatment for such scales to protect water quality in densely populated urban regions. Plants of this size in China typically employ secondary or tertiary treatment processes to meet the national discharge standards (GB 18918-2002). The designed capacity is 1.00 million cubic meters per day, indicating a large-scale infrastructure capable of handling significant wastewater volumes from the surrounding urban and industrial areas. The plant's treated effluent is discharged into local waterways that ultimately flow into the Yangtze River, one of the world's major river systems. The Yangtze basin supports diverse aquatic life and provides water for millions of people downstream. Effective treatment at this plant is crucial for reducing nutrient and pollutant loads, thereby protecting the ecological health of the river and its associated lakes and wetlands.
Environmental context
The plant discharges into the Yangtze River basin, which drains into the East China Sea. The Yangtze is a critical freshwater resource and supports a rich ecosystem, including migratory fish species and wetland habitats. Downstream, the river passes through major cities and agricultural areas, making nutrient and pollutant control essential to prevent eutrophication and maintain water quality for human and ecological use.
