Overview
Chongqing wastewater treatment plant serves Yunyang County in Chongqing, China, with a designed capacity of 1.00 unit and a population served of 130,000. It is located within 50 km of the coast, discharging into the Yangtze River basin.
The Chongqing wastewater treatment plant is located in Yunyang County, Chongqing, China, at Qixing Square on Yimin Avenue. It serves a population of approximately 130,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1. Under China's national wastewater standards, plants serving populations over 100,000 are typically required to achieve secondary treatment or higher, with nutrient removal in sensitive areas. The plant's location within 50 km of the coast suggests potential discharge into the Yangtze River system, which flows eastward to the East China Sea. Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits on BOD, COD, suspended solids, and nutrients. The plant's receiving water body is likely a tributary of the Yangtze River, which ultimately drains into the East China Sea. The Yangtze basin supports diverse aquatic life and is a critical water resource for millions. Proper treatment at this facility helps protect downstream ecosystems and water quality in the Three Gorges Reservoir region.
Environmental context
The plant discharges into the Yangtze River basin, which flows through Chongqing and eventually reaches the East China Sea. The Yangtze is one of the world's most biodiverse rivers, supporting species such as the Chinese sturgeon and finless porpoise. Downstream, the Three Gorges Reservoir alters flow and sediment dynamics, making nutrient and pollutant control crucial for maintaining aquatic health and preventing eutrophication in the reservoir and coastal waters.
