Overview
Jiangsu wastewater treatment plant serves Changshu City in Jiangsu Province, China, with a designed capacity of 1.00 and a population equivalent of 93,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Changshu City, Jiangsu Province, China, within the Yangtze River Delta region. It serves a population equivalent of 93,000, placing it in the medium-to-large agglomeration category under Chinese municipal wastewater regulations. The plant's designed capacity is 1. As a facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For a plant of this scale, secondary biological treatment with nutrient removal is typically required to meet Class 1A or 1B standards, depending on the receiving water's sensitivity. The plant likely employs an activated sludge process or similar technology to achieve compliance. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River and the East China Sea. Its location in a densely populated and industrialized region means it plays a critical role in protecting downstream water quality and aquatic ecosystems. The Yangtze River Delta is a major ecological and economic zone, and effective wastewater treatment is essential for maintaining water resources and supporting biodiversity.
Environmental context
The plant's treated effluent flows into the local river network within the Yangtze River basin, eventually reaching the East China Sea. The Yangtze River Delta is a highly productive estuarine ecosystem that supports diverse aquatic life, including migratory fish species. Downstream waters are sensitive to nutrient loading, and the plant's performance directly affects water quality in this ecologically important region.
