Jiangsu Wastewater Treatment Plant, Hanjiang District, Yangzhou, China

The Jiangsu wastewater treatment plant is located in Bali Town, Hanjiang District, Yangzhou City, Jiangsu Province, China. It serves a population of 510,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant has a designed capacity of 1.00 million cubic meters per day, indicating substantial infrastructure to handle municipal wastewater from the urban area. As a large-scale facility in China, the plant is expected to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. Chinese regulations require secondary treatment as a minimum for urban wastewater plants, with tertiary treatment often mandated in sensitive watersheds or densely populated regions like the Yangtze River Delta. It likely incorporates biological treatment to comply with effluent quality standards. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River, one of China's most important water bodies. The Yangtze River basin supports diverse aquatic ecosystems and provides drinking water for millions. The plant plays a critical role in protecting downstream water quality and preventing eutrophication in the river and its estuary.

The plant discharges into the Yangtze River basin, which flows eastward through Jiangsu Province and empties into the East China Sea. The Yangtze River is a vital ecological corridor supporting numerous fish species and migratory birds. Downstream, the river's estuary and coastal waters are ecologically sensitive, requiring stringent nutrient removal to prevent algal blooms and hypoxia. The plant's operations help maintain water quality in this densely populated and industrially active region.
