Overview
Jiangsu wastewater treatment plant serves Lianshui County, Jiangsu Province, China, with a population of 276,000. It operates under China's national wastewater standards.
The Jiangsu wastewater treatment plant is located in Lianshui County, Huai'an City, Jiangsu Province, China. It serves a population of approximately 276,000, classifying it as a large-scale municipal facility within the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to meet Class 1-A or 1-B effluent limits, which include biological treatment and nutrient removal. Regulatory expectations for this scale emphasize advanced treatment to protect downstream water bodies. The plant discharges into the local watershed, which ultimately drains into the Huai River system and then to the Yellow Sea. The Huai River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is critical to prevent eutrophication and maintain water quality in this densely populated region.
Environmental context
The plant's treated effluent enters the Huai River basin, a major waterway in eastern China that flows into the Yellow Sea. The Huai River and its tributaries support extensive agricultural irrigation and freshwater fisheries. Downstream, the river passes through several provinces before reaching the coast, where nutrient loading can contribute to algal blooms in coastal waters. Protecting this watershed is essential for regional water security and ecological balance.
