Overview
Jiangsu wastewater treatment plant serves 460,000 people in Changshu, Jiangsu Province, China. It is located within 50 km of the coast and discharges into local waterways.
The Jiangsu wastewater treatment plant is located in Changshu, a city in Jiangsu Province, China, serving a population of 460,000. The plant is situated in the Yangtze River Delta region, an area with dense urban and industrial development. As a large-scale municipal facility, it plays a key role in managing wastewater from the city and surrounding areas. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban plants serving populations over 100,000. The designed capacity is 1.00 (likely in cubic meters per day, though units are unspecified), indicating a substantial infrastructure investment. Chinese regulations mandate that such facilities meet Class 1A or 1B standards for effluent quality before discharge. The plant's treated effluent ultimately flows into the Yangtze River basin, which drains into the East China Sea. The Yangtze River Delta is ecologically significant, supporting diverse aquatic life and providing water resources for millions. Proper treatment is critical to prevent eutrophication and protect downstream coastal ecosystems.
Environmental context
The plant discharges into the Yangtze River basin, which flows through eastern China and empties into the East China Sea. This watershed supports extensive fisheries and biodiversity, including migratory fish species. The coastal proximity means that nutrient loads from treated effluent can affect marine water quality, making advanced treatment important for protecting the downstream environment.
