Overview
Jiangsu wastewater treatment plant serves Jintan District, Changzhou, Jiangsu Province, China. The facility supports a population of 100,000 and operates under China's national wastewater regulations.
The Jiangsu wastewater treatment plant is located in Jintan District, Changzhou, within Jiangsu Province, China. It serves a population of approximately 100,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated along Yanhe East Road in the Yuchi community, reflecting its role in municipal sanitation for this urban area. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to achieve secondary treatment with nutrient removal, especially in sensitive watersheds. The facility's treatment processes and capacity are aligned with these regulatory expectations, ensuring compliance with effluent quality standards for organic matter, suspended solids, and nutrients. The plant discharges treated wastewater into local waterways that ultimately drain into the Yangtze River Delta region, a densely populated and ecologically significant area. The receiving water bodies support diverse aquatic life and are critical for regional water supply and agriculture. Proper treatment at this facility helps protect downstream ecosystems and maintain water quality in the broader Changzhou area.
Environmental context
The plant's treated effluent flows into the local river network within the Yangtze River Basin, eventually reaching the East China Sea. This watershed supports important aquatic habitats and is a key resource for drinking water and irrigation in Jiangsu Province. The region's dense population and industrial activity necessitate robust wastewater treatment to prevent eutrophication and protect biodiversity in downstream lakes and coastal zones.
