Overview
Jiangsu wastewater treatment plant serves Wujin District, Changzhou, China, with a population equivalent of 190,000. The facility has a designed capacity of 1.00 (units unspecified) and is located inland, over 50 km from the coast.
The Jiangsu wastewater treatment plant is situated in the Hebei First Industrial Park within the Wujin High-tech Zone, Wujin District, Changzhou, Jiangsu Province, China. It serves a population equivalent of 190,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a large-scale facility in China, the plant is expected to comply with the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment as a minimum, with tertiary treatment required for sensitive receiving waters. Facilities of this scale typically employ biological treatment processes such as activated sludge or A2O. The plant discharges treated wastewater into local water bodies within the Yangtze River Delta region. The treated effluent ultimately flows into the Yangtze River via the Grand Canal or local tributaries, contributing to the water quality management of this densely populated and industrialized area. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water reuse initiatives in the region.
Environmental context
The plant is located in the Yangtze River Delta, one of China's most economically developed and water-sensitive regions. Treated effluent likely enters the Grand Canal or local rivers, which drain into the Yangtze River and eventually the East China Sea. The downstream environment supports diverse aquatic life and is crucial for fisheries, agriculture, and drinking water supplies. Effective treatment is essential to prevent eutrophication and protect the ecological health of the Yangtze estuary.
Frequently asked questions
The plant is located in the Hebei First Industrial Park, Wujin High-tech Zone, Wujin District, Changzhou, Jiangsu Province, China.
The plant serves a population equivalent of 190,000, classifying it as a large agglomeration under Chinese wastewater standards.
The plant has a designed capacity of 1.00 (units unspecified), though typical large plants in China have capacities in the tens of thousands of cubic meters per day.
The plant operates under China's GB 18918-2002 standard, which sets discharge limits for pollutants. Large agglomerations like this are required to achieve at least secondary treatment, with tertiary treatment in sensitive areas.
Plants of this scale commonly use biological treatment processes such as activated sludge, A2O (anaerobic-anoxic-oxic), or oxidation ditches, often followed by disinfection. Advanced treatment may be added for water reuse.
