Overview
Anhui wastewater treatment plant serves Dingyuan Economic Development Zone in Chuzhou, Anhui, China, with a population equivalent of 178,900. The facility operates under China's national wastewater discharge standards.
The Anhui wastewater treatment plant is located in Dingyuan Economic Development Zone, Dingcheng Town, Dingyuan County, Chuzhou City, Anhui Province, China. It serves a population equivalent of 178,900, classifying it as a large-scale municipal facility within the region. 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 conventional pollutants, nutrients, and heavy metals. For agglomerations of this size, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant discharges treated wastewater into local water bodies that ultimately drain into the Yangtze River basin via the Huaihe River system. The downstream environment supports agricultural irrigation and freshwater ecosystems, making effective nutrient and pathogen removal critical for protecting water quality and public health.
Environmental context
The plant's treated effluent enters local waterways within the Huaihe River basin, a major tributary of the Yangtze River. This watershed supports intensive agriculture and provides drinking water for millions. Nutrient loading from wastewater can contribute to eutrophication in downstream lakes and reservoirs, so advanced treatment is essential for maintaining ecological balance.
