Overview
Jiangsu wastewater treatment plant in Tianning District, Changzhou, serves 30,000 people. It operates under China's national wastewater standards, discharging treated effluent into local waterways.
The Jiangsu wastewater treatment plant is located in Tianning District, Changzhou, Jiangsu Province, China. It serves a population of approximately 30,000 people, placing it in the small-to-medium agglomeration category. The plant is situated inland, more than 50 km from the coast, and its treated effluent is discharged into the local river network. The plant operates under China's national wastewater discharge standards (GB 18918-2002), which mandate secondary treatment for municipal plants of this scale. The designed capacity is 1.00 (likely in 10,000 m³/day or similar units), indicating a facility sized for the served population. Compliance with local environmental protection bureau permits ensures regulated discharge quality. The plant's receiving water body is part of the Yangtze River Delta basin, ultimately draining into the East China Sea. The local watershed supports dense urban and industrial areas, making effective wastewater treatment critical for preventing eutrophication and protecting downstream aquatic ecosystems. The plant contributes to maintaining water quality in the region's intricate canal and river system.
Environmental context
The plant discharges into the Yangtze River Delta watershed, a densely populated and industrialized region. Treated effluent flows through local canals and rivers into the Yangtze River estuary and eventually the East China Sea. The watershed supports diverse aquatic life and is an important migratory corridor for fish. Effective treatment is essential to mitigate nutrient loading and protect downstream water quality.
