Overview
Jiangsu wastewater treatment plant serves 210,000 people in Chongchuan, Nantong, Jiangsu, China. Located within 50 km of the coast, it operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Chongchuan District, Nantong, Jiangsu Province, China, serving a population of 210,000. It is situated in the Nantong Economic and Technological Development Zone, an area with significant industrial activity. The plant's designed capacity is 1. As a large-scale municipal facility, it is subject to China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment and nutrient removal for plants serving populations over 100,000. The plant's proximity to the coast (within 50 km) suggests its effluent may eventually reach the East China Sea, requiring compliance with stricter discharge limits for sensitive coastal areas. The plant plays a key role in managing wastewater from the urban and industrial zones of Nantong, protecting local water bodies and the downstream marine environment.
Environmental context
The plant discharges treated wastewater into local waterways that ultimately drain into the Yangtze River estuary and the East China Sea. This coastal region supports diverse aquatic life, including fisheries and migratory species. The plant's operation is critical for reducing nutrient and pollutant loads that could contribute to eutrophication and harm marine ecosystems in the Yangtze River Delta.
