Overview
Jiangsu wastewater treatment plant serves 28,000 people in Changshu, Jiangsu Province, China. It is located within 50 km of the coast and discharges into the Yangtze River Delta watershed.
The Jiangsu wastewater treatment plant is located in Wangshi, Haiyu Town, Changshu City, Suzhou, Jiangsu Province, China. It serves a population of approximately 28,000, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant is situated in the densely populated Yangtze River Delta region, an area with significant industrial and urban development. Designed capacity is 1.00 (units unspecified, likely million cubic meters per day or similar). As a Chinese municipal plant, it operates under national discharge standards (GB 18918-2002) which mandate secondary treatment as a minimum, with tertiary treatment required for sensitive water bodies. Typical plants of this scale in the region employ biological treatment processes such as activated sludge. The plant's treated effluent likely discharges into local waterways that flow into the Yangtze River, eventually reaching the East China Sea. The Yangtze River Delta is an ecologically and economically vital region, supporting diverse aquatic life and serving as a major migratory corridor for fish and birds. Proper wastewater treatment is critical to protect water quality in this densely populated and industrialized area.
Environmental context
The plant is located in the Yangtze River Delta, one of China's most important watersheds. Treated effluent likely enters local canals or rivers that drain into the Yangtze River, which flows into the East China Sea. The delta supports extensive wetlands and fisheries, and nutrient pollution from urban and agricultural runoff is a key concern. The plant's discharge contributes to the overall nutrient load in the basin, making effective treatment essential for downstream ecosystem health.
Frequently asked questions
The plant is located in Wangshi, Haiyu Town, Changshu City, Suzhou, Jiangsu Province, China, in the Yangtze River Delta region.
The plant serves approximately 28,000 people, classifying it as a medium-sized municipal wastewater treatment facility.
Treated effluent is discharged into local waterways that flow into the Yangtze River, eventually reaching the East China Sea.
The plant operates under China's national discharge standard GB 18918-2002, which sets limits for pollutants like COD, BOD, and nutrients. Plants serving over 10,000 people typically require secondary treatment.
For medium-sized agglomerations in China, secondary biological treatment (e.g., activated sludge) is standard. In sensitive areas like the Yangtze River Delta, tertiary treatment may be required to reduce nitrogen and phosphorus.
