Overview
Chongqing wastewater treatment plant serves 76,000 people in Wanzhou District, Chongqing, China. It operates under China's national wastewater standards within the Yangtze River basin.
The Chongqing wastewater treatment plant is located in the Wanzhou District of Chongqing, China, serving a population of approximately 76,000. The facility is situated in the mountainous region of southwestern China, near the Yangtze River, which is the country's longest waterway and a critical ecological and economic resource. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater. For a facility serving a medium-sized agglomeration like this, compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) is expected, which sets limits on key pollutants such as COD, BOD, and ammonia nitrogen. The plant's treated effluent likely discharges into a tributary of the Yangtze River, ultimately flowing into the East China Sea. The Yangtze basin supports diverse aquatic life, including endangered species like the Chinese sturgeon and finless porpoise. Proper treatment is essential to protect water quality in this densely populated and ecologically sensitive region.
Environmental context
The plant's receiving water body is likely a tributary of the Yangtze River, which flows through Chongqing and eventually reaches the East China Sea. The Yangtze basin is a vital freshwater ecosystem supporting fisheries, agriculture, and biodiversity. Downstream areas include the Three Gorges Reservoir, which requires strict pollution control to prevent eutrophication and protect drinking water sources for millions of people.
