Overview
Jiangsu wastewater treatment plant serves Wujin District, Changzhou, China, with a population equivalent of 340,000. The facility has a designed capacity of 1.00 unit, operating under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Wujin District, Changzhou, within Jiangsu Province, China. It serves a population equivalent of 340,000, classifying it as a large-scale municipal facility in the Yangtze River Delta region. The plant is situated in an urbanized area with significant industrial activity. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For facilities serving over 100,000 people, Chinese regulations typically require secondary biological treatment with nutrient removal, especially in sensitive water bodies. The designed capacity of 1.00 unit suggests a substantial treatment capability. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin. The Yangtze River Delta is a densely populated and economically vital region, where wastewater treatment plays a critical role in protecting water quality and aquatic ecosystems. Proper treatment helps reduce nutrient loading and industrial pollutants entering the river system.
Environmental context
The plant's treated effluent flows into the local canal network within the Yangtze River basin, eventually reaching the Yangtze River and the East China Sea. The Yangtze River Delta is ecologically sensitive, supporting diverse aquatic life and serving as a critical migratory corridor for fish species. Nutrient pollution from urban and agricultural runoff poses a significant challenge in this region, making advanced wastewater treatment essential for maintaining downstream water quality and ecosystem health.
