Overview
Anhui wastewater treatment plant serves Xiangshan District, Huaibei, Anhui, China, with a population equivalent of 750,000. It operates under China's national wastewater standards.
The Anhui wastewater treatment plant is located in Xiangshan District, Huaibei City, Anhui Province, China. It serves a population of approximately 750,000, classifying it as a large-scale municipal facility within the region's urban wastewater infrastructure. As a large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Typical plants of this scale employ activated sludge processes with biological nitrogen and phosphorus removal to comply with national effluent limits. The plant discharges treated wastewater into local waterways that ultimately drain into the Huai River basin, a major water system in eastern China. The Huai River flows eastward into Hongze Lake and then to the Yellow Sea. Protecting this watershed is critical for downstream aquatic ecosystems and water supply for agriculture and communities.
Environmental context
The plant's treated effluent enters the Huai River basin, which flows through Anhui and Jiangsu provinces before reaching Hongze Lake and the Yellow Sea. The Huai River supports diverse aquatic life and provides irrigation and drinking water for millions. Nutrient pollution from wastewater can cause eutrophication in downstream lakes, so advanced treatment is essential for maintaining water quality in this densely populated region.
Frequently asked questions
The plant is located in Xiangshan District, Huaibei City, Anhui Province, China, near the intersection of Waihuan Road and Wuliying.
The plant serves approximately 750,000 people, making it a large-scale municipal facility.
The treated wastewater is discharged into local waterways that flow into the Huai River basin, eventually reaching Hongze Lake and the Yellow Sea.
The plant must comply with China's GB 18918-2002 standard, which sets discharge limits for pollutants like COD, BOD, ammonia, and phosphorus, requiring secondary treatment with nutrient removal for large agglomerations.
Plants of this scale typically use activated sludge processes with biological nitrogen and phosphorus removal, often including anaerobic-anoxic-oxic (A2O) or sequencing batch reactors (SBR) to meet stringent effluent standards.
