Jiangsu Wastewater Treatment Plant, Jiangdu District, Yangzhou, China

The Jiangsu wastewater treatment plant is located in Xiannv Town, Jiangdu District, Yangzhou City, Jiangsu Province, China. It serves a population of approximately 320,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. Under China's national wastewater discharge standards, plants serving populations over 100,000 are typically required to achieve secondary treatment with nutrient removal, especially in sensitive watersheds. The Jiangsu plant is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for COD, BOD, ammonia nitrogen, and total phosphorus. Regulatory requirements for this scale of facility are stringent. The plant discharges into the local water system, which ultimately drains into the Yangtze River basin. The Yangtze River is one of the world's most important freshwater ecosystems, supporting diverse aquatic life and providing water for millions of people. The plant's operations contribute to protecting downstream water quality in the Yangtze River and its tributaries, which flow into the East China Sea.

The Jiangsu plant is located in the Yangtze River basin, one of China's most ecologically and economically significant watersheds. The Yangtze River flows eastward through Jiangsu Province and discharges into the East China Sea near Shanghai. The river supports a rich diversity of fish species, including the endangered Chinese sturgeon, and provides critical habitat for migratory birds. The plant's treated effluent must meet strict standards to prevent eutrophication and protect downstream aquatic ecosystems, particularly in the Yangtze River estuary and coastal zone.
