Overview
The Jiangsu wastewater treatment plant serves Yixing City in Jiangsu Province, China, with a designed capacity of 1.00 and a population equivalent of 85,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Yixing City, within the Wuxi prefecture of Jiangsu Province, China. It serves a population equivalent of 85,000, classifying it as a medium-sized municipal facility. The plant is situated in the Yangtze River Delta region, a densely populated and industrialized area. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national standard sets effluent limits for conventional pollutants and nutrients, with stricter requirements for plants discharging into sensitive water bodies. For a facility of this scale, secondary treatment with nutrient removal is typically expected. The plant's treated effluent likely discharges into local waterways that ultimately flow into Lake Taihu, a large freshwater lake of ecological and economic importance. Lake Taihu has experienced severe eutrophication due to nutrient pollution, making advanced treatment crucial for protecting water quality. The plant's location within 50 km of the coast also means its discharge could influence coastal ecosystems.
Environmental context
The plant is located in the Yangtze River Delta, a region with dense river networks. Its treated effluent likely enters tributaries of Lake Taihu, China's third-largest freshwater lake. Lake Taihu is a critical water source for drinking, irrigation, and industry, but has suffered from algal blooms due to excess nitrogen and phosphorus. Downstream, the lake drains into the Yangtze River via the Suzhou Creek, eventually reaching the East China Sea. The plant's discharge contributes to the nutrient load in this sensitive watershed, highlighting the need for effective nutrient removal.
Frequently asked questions
The plant is located in Yixing City, Wuxi prefecture, Jiangsu Province, China, in the Yangtze River Delta region.
The plant serves a population equivalent of 85,000, classifying it as a medium-sized municipal wastewater treatment facility.
The plant has a designed capacity of 1. For a population of 85,000, typical capacity would be in the range of tens of thousands of cubic meters per day.
The plant operates under China's national standard GB 18918-2002, which sets discharge limits for pollutants. Plants serving over 100,000 PE in sensitive areas may require tertiary treatment, but for this scale, secondary treatment with nutrient removal is typical.
The plant likely discharges into local waterways that flow into Lake Taihu, a large freshwater lake. Lake Taihu drains into the Yangtze River and eventually the East China Sea.
