Jiangsu Wastewater Treatment Plant, Dantu District, Zhenjiang | China

The Jiangsu wastewater treatment plant is located in Dantu District, Zhenjiang, Jiangsu Province, China. It serves a population equivalent of approximately 30,000, placing it in the small-to-medium agglomeration category. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in regions like Jiangsu that are part of the Yangtze River Delta, where water quality protection is prioritized. The plant discharges 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. Proper treatment at this facility helps reduce pollutant loads to the river and its downstream estuary, contributing to the ecological health of the region.

The plant is located in the Yangtze River Delta, a densely populated and economically vital region. Treated effluent likely enters local canals or tributaries that flow into the Yangtze River, which discharges into the East China Sea. The Yangtze basin supports critical fish spawning grounds and migratory species, making nutrient and pollutant control essential for downstream aquatic health.
