Overview
Jiangsu wastewater treatment plant serves 700,000 people in Liangxi District, Wuxi, Jiangsu Province, China. The facility is located within 50 km of the coast and discharges into the local water system.
The Jiangsu wastewater treatment plant is a major municipal facility located in Liangxi District, Wuxi, within Jiangsu Province, China. It serves a population of approximately 700,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated along the Grand Canal and near the Yangtze River Delta, a densely populated and industrialized region. As a large-scale plant, it is expected to meet stringent discharge standards under China's Environmental Protection Law and the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard requires advanced treatment with nutrient removal for plants in sensitive areas, which likely applies here given the proximity to the Yangtze River estuary and coastal waters. The designed capacity is 1.00 (likely in hundred thousand cubic meters per day), indicating a substantial treatment capability. The plant's treated effluent ultimately flows into the Yangtze River via local waterways, and then into the East China Sea. This downstream environment supports diverse aquatic life and is an important fishing ground. The plant plays a critical role in protecting water quality in the region, reducing nutrient and pollutant loads that could otherwise contribute to eutrophication in coastal waters.
Environmental context
The plant discharges into the Grand Canal system, which connects to the Yangtze River, one of the world's major rivers. The Yangtze flows into the East China Sea, a productive marine ecosystem supporting fisheries and biodiversity. The region is ecologically sensitive due to high population density and industrial activity, making effective wastewater treatment essential to prevent eutrophication and protect downstream habitats.
Frequently asked questions
The plant is located in Liangxi District, Wuxi, Jiangsu Province, China, along the Grand Canal.
The plant serves approximately 700,000 people, making it a large-scale municipal facility.
Treated wastewater is discharged into the Grand Canal, which flows into the Yangtze River and eventually the East China Sea.
The plant operates under China's GB 18918-2002 discharge standard, which requires advanced treatment with nutrient removal for large plants in sensitive areas.
Plants of this scale in China typically employ secondary treatment followed by advanced nutrient removal, including biological nitrogen and phosphorus removal, to meet strict effluent standards.
