Overview
Anhui wastewater treatment plant serves Huainan City, Anhui Province, China, with a population equivalent of 140,000. It operates under China's national wastewater discharge standards.
The Anhui wastewater treatment plant is located in Huainan City, Anhui Province, China, serving a population equivalent of 140,000. The facility is situated in the Huai River basin, a major waterway in eastern China. As a medium-to-large agglomeration, the plant plays a key role in managing municipal wastewater for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to meet Class 1A or 1B effluent limits, which include biological treatment and nutrient removal. Regulatory expectations for this population tier emphasize secondary treatment with advanced nutrient control to protect receiving waters. The treated effluent likely discharges into the Huai River system, which flows eastward into Hongze Lake and eventually to the Yellow Sea. The Huai River basin supports extensive agriculture and fisheries, making effective wastewater treatment critical for maintaining water quality and ecosystem health in this densely populated region.
Environmental context
The plant discharges into the Huai River basin, a major tributary system that flows through Anhui and Jiangsu provinces before reaching Hongze Lake and the Yellow Sea. The Huai River is a vital water source for irrigation, industry, and domestic use, and its ecological health is sensitive to nutrient loading from urban wastewater. Effective treatment helps prevent eutrophication and protects downstream aquatic habitats.
