Overview
Jiangsu wastewater treatment plant serves Lianshui County, Huai'an, Jiangsu, China, with a population of 23,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Lianshui County, Huai'an, Jiangsu Province, China. It serves a population of approximately 23,000 people, making it a medium-scale facility within the region's municipal wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For agglomerations of this size, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant discharges treated effluent into local waterways that eventually drain into the Huai River basin, a major water system in eastern China. The Huai River flows eastward into the Yellow Sea, supporting agricultural irrigation, fisheries, and aquatic ecosystems. Proper treatment is essential to protect downstream water quality and ecological health.
Environmental context

The Huai River system supports diverse aquatic life and is a critical water source for agriculture and industry. Downstream areas include ecologically sensitive wetlands and coastal zones that benefit from controlled nutrient and pollutant loads.
