Overview
Jiangsu wastewater treatment plant serves Danyang, Jiangsu, China, with a population of 50,000. It operates under China's national wastewater standards, ensuring treated effluent meets environmental requirements.
The Jiangsu wastewater treatment plant is located in Danyang, Jiangsu Province, China, serving a population of approximately 50,000. Situated in the Yangtze River Delta region, the plant is part of the municipal infrastructure for the city of Danyang, which lies within Zhenjiang prefecture. The facility plays a key role in managing wastewater from residential and industrial sources in the area. As a medium-sized agglomeration, the plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits on key pollutants such as COD, BOD, and nutrients. Plants of this scale typically employ biological treatment (e.g., activated sludge) to achieve secondary or advanced standards. The population served indicates a facility of moderate size. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River, one of China's major river systems. The Yangtze River basin supports diverse aquatic life and provides water for millions of people downstream. Proper treatment is essential to protect water quality in this ecologically and economically vital region.
Environmental context
The plant discharges into tributaries of the Yangtze River, which flows eastward into the East China Sea. The Yangtze River basin is a critical freshwater ecosystem supporting numerous fish species and migratory birds. The region faces pressures from industrial and agricultural runoff, making effective wastewater treatment crucial for maintaining water quality and preventing eutrophication in downstream lakes and coastal areas.
