Overview
Jiangsu wastewater treatment plant serves Tongzhou District, Nantong, Jiangsu, China, with a population equivalent of 113,000. The plant has a designed capacity of 1.00 (units unspecified) and discharges into local waterways.
The Jiangsu wastewater treatment plant is located in Tongzhou District, Nantong City, Jiangsu Province, China. It serves a population equivalent of 113,000, classifying it as a medium-to-large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1. Indicating its scale in treating municipal wastewater from the surrounding urban area. As a facility in China, the plant operates under national wastewater discharge standards, which typically require secondary treatment for urban wastewater. For agglomerations of this size, compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) is expected, which sets limits on biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients. The plant discharges treated effluent into local water bodies that ultimately drain into the Yangtze River Delta region, a densely populated and economically vital area. The receiving waters support diverse aquatic life and are important for regional water supply and agriculture. Proper treatment helps protect downstream ecosystems and reduce nutrient loading into the East China Sea.
Environmental context
The plant's treated effluent flows into the local river network within the Yangtze River Delta, eventually reaching the East China Sea. This region is ecologically sensitive, supporting fisheries and migratory bird habitats. Nutrient and pollutant control from wastewater treatment is critical to prevent eutrophication and maintain water quality in downstream coastal areas.

The plant serves a population equivalent of 113,000, classifying it as a medium-to-large agglomeration under Chinese wastewater regulations.
Treated effluent is discharged into local waterways within the Yangtze River Delta, eventually reaching the East China Sea.
The plant operates under China's national wastewater discharge standards, primarily GB 18918-2002, which sets effluent limits for pollutants. For agglomerations of this scale, secondary treatment is typically required.
Plants of this size in China generally employ secondary biological treatment processes such as activated sludge or oxidation ditches, often with nutrient removal to meet GB 18918-2002 standards.
