Overview
Jiangsu wastewater treatment plant serves Huishan District, Wuxi, Jiangsu, China, with a designed capacity of 1.00 and a population equivalent of 80,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Huishan District, Wuxi, within Jiangsu Province, China. It serves a population equivalent of 80,000 and has a designed capacity of 1.00, indicating a medium-scale facility for the region. As a Chinese municipal wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. Plants of this scale typically employ biological treatment processes such as activated sludge or A2O to meet Class 1A or 1B standards, depending on the receiving water sensitivity. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River Delta, a densely populated and economically vital region. The downstream environment includes the Taihu Lake basin, which is ecologically sensitive due to historical eutrophication issues, making nutrient removal critical for protecting water quality and aquatic ecosystems.
Environmental context
The treated effluent from this plant flows into the local river network within the Yangtze River Delta, eventually reaching the East China Sea. The downstream Taihu Lake basin is a major freshwater resource that has faced eutrophication challenges, requiring strict nutrient control to prevent algal blooms and protect biodiversity. The plant's discharge contributes to the overall water quality management in this densely populated and industrially active region.
Frequently asked questions
The plant is located in Huishan District, Wuxi, Jiangsu Province, China, specifically in the Xizhang area of Yanqiao Subdistrict.
The plant serves a population equivalent of 80,000 people, classifying it as a medium-scale agglomeration under Chinese wastewater management standards.
The treated effluent is discharged into local waterways that are part of the Yangtze River Delta drainage network, ultimately reaching the East China Sea.
The plant operates under China's national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for COD, BOD, ammonia, and phosphorus. Plants of this scale typically require secondary biological treatment with nutrient removal.
For a medium-scale plant like this, standard practice includes secondary biological treatment (e. g. , activated sludge or A2O) followed by disinfection, often achieving Class 1A or 1B standards to protect sensitive downstream water bodies such as Taihu Lake.
