Jiangsu Wastewater Treatment Plant, Hanjiang District, Yangzhou, China

The Jiangsu wastewater treatment plant is located in Bali Town, Hanjiang District, Yangzhou, Jiangsu Province, China. It serves a population of 500,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a major facility in Jiangsu Province, the plant is subject to China's national discharge standards, which require secondary treatment as a minimum for urban wastewater. For plants serving over 100,000 people, advanced treatment may be mandated in sensitive areas to reduce nutrient pollution. The plant discharges into local waterways that ultimately drain into the Yangtze River basin, one of China's most ecologically and economically significant river systems. The Yangtze River supports diverse aquatic life and provides water for millions of people downstream. Proper treatment at this plant helps protect water quality in the Yangtze estuary and the East China Sea.

The plant is located in the Yangtze River Delta, a densely populated and industrialized region. Treated effluent likely enters local canals or tributaries that flow into the Yangtze River, which empties into the East China Sea. The Yangtze basin is ecologically sensitive, supporting species such as the Chinese sturgeon and finless porpoise. Nutrient and pollutant loads from urban areas must be carefully managed to prevent eutrophication and habitat degradation in downstream waters.
