Overview
Jiangsu wastewater treatment plant serves Xuzhou, Jiangsu, China, with a population equivalent of 190,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Zhaodun Town, Xuzhou City, Jiangsu Province, China. It serves a population equivalent of 190,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. 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 plants serving over 100,000 people, Class 1-A standards typically apply, requiring advanced treatment including biological nutrient removal. The plant discharges treated effluent into local waterways within the Huai River basin, which ultimately drains into the Yellow Sea. The receiving waters support agricultural irrigation and aquatic ecosystems, making nutrient removal critical to prevent eutrophication in downstream lakes and coastal zones.
Environmental context
The plant's treated effluent enters the Huai River system, which flows eastward into the Yellow Sea. This watershed is heavily utilized for agriculture and supports diverse freshwater habitats. Nutrient loading from urban wastewater is a key concern in this region, as it can contribute to algal blooms in downstream lakes and coastal areas, affecting water quality and biodiversity.
