Overview
The Jiangsu wastewater treatment plant serves Liyang City in Jiangsu Province, China, with a population equivalent of 280,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in the Qing'an area of Liyang City, within Changzhou Prefecture, Jiangsu Province, China. It serves a population equivalent of 280,000, placing it in the large agglomeration category under Chinese regulatory frameworks. The plant is situated in the Yangtze River Delta region, a densely populated and economically active area. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for conventional pollutants, nutrients, and pathogens. For plants of this size, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The regulatory framework ensures compliance with national standards. The treated effluent from the plant likely discharges into local waterways that ultimately flow into the Yangtze River or its tributaries, contributing to the broader Yangtze River Basin. This basin is ecologically significant, supporting diverse aquatic life and providing water resources for millions of people downstream. The plant plays a key role in protecting water quality in this densely populated and industrialized region.
Environmental context
The plant is located in the Yangtze River Delta, one of China's most important economic and ecological regions. Its treated effluent likely enters local rivers that drain into the Yangtze River, which flows into the East China Sea. The Yangtze River Basin supports a wide range of aquatic species, including the endangered Yangtze finless porpoise, and is a critical water source for agriculture, industry, and domestic use. Effective wastewater treatment is essential to prevent eutrophication and protect downstream ecosystems.
