Overview
Jiangsu wastewater treatment plant serves 450,000 people in Chongchuan District, Nantong, Jiangsu, China. Located within 50 km of the coast, it discharges into local waterways flowing to the East China Sea.
The Jiangsu wastewater treatment plant is located in the Chongchuan District of Nantong, Jiangsu Province, China. It serves a population of 450,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated near the Yangtze River delta, an economically vital and densely populated region. As a large-scale facility, the plant is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law, which mandates advanced treatment for sensitive areas. Plants of this size typically employ biological treatment with nutrient removal to comply with Class 1A or 1B standards. The designed capacity is 1.00 (likely in 10,000 m³/day), indicating substantial infrastructure. The plant's treated effluent ultimately reaches the Yangtze River estuary and the East China Sea. This coastal discharge zone supports diverse marine life and is an important fishing ground. The plant plays a critical role in protecting downstream water quality and the ecological health of the Yangtze delta ecosystem.
Environmental context
The plant discharges into local waterways that flow into the Yangtze River, which empties into the East China Sea near Nantong. The Yangtze estuary is a vital ecological zone supporting migratory fish, crustaceans, and waterbirds. As a large coastal agglomeration, the plant's nutrient removal performance directly affects downstream algal blooms and marine habitat quality in the East China Sea.
Frequently asked questions
The plant is located in Chongchuan District, Nantong, Jiangsu Province, China, near the intersection of Huanghai Road and Yongyang Road.
The plant serves approximately 450,000 people, classifying it as a large agglomeration under Chinese wastewater regulations.
Treated effluent is discharged into local waterways that flow into the Yangtze River, ultimately reaching the East China Sea.
The plant operates under China's Water Pollution Prevention and Control Law, which sets discharge standards for municipal wastewater. Large plants like this typically must meet Class 1A or 1B standards, requiring biological treatment and nutrient removal.
For a plant of this scale in China, standard treatment includes primary sedimentation, biological treatment (e. g. , activated sludge), and disinfection. Advanced nutrient removal is often required to protect sensitive coastal waters.
