Overview
Beijing wastewater treatment plant serves Huairou District, Beijing, China, with a population equivalent of 120,000. The facility operates under China's national wastewater discharge standards.
The Beijing wastewater treatment plant is located in Huairou District, a suburban area of Beijing, China. It serves a population equivalent of 120,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. The plant is situated near the Chunhui Road area, adjacent to the Foton Daimler automotive factory, indicating a mix of domestic and industrial influent. As a facility in China, the plant must comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants. For a plant of this scale, secondary treatment with nutrient removal is typically required, especially given the environmental sensitivity of the region. The plant's discharge likely undergoes biological treatment to meet Class 1A or 1B standards, depending on the receiving water body's classification. The treated effluent is discharged into local waterways that ultimately flow into the Hai River system, which drains into the Bohai Sea. The Hai River basin is a critical water resource for northern China, supporting agriculture, industry, and urban water supply. The plant plays a key role in protecting downstream water quality and reducing pollution loads to the Bohai Sea, which is subject to eutrophication and algal blooms from nutrient inputs.
Environmental context
The plant's discharge enters the local drainage network within the Hai River basin, which flows eastward into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it vulnerable to nutrient enrichment and harmful algal blooms. The Hai River system receives substantial urban and industrial runoff from Beijing and surrounding areas, so effective treatment at this plant is essential for reducing nitrogen and phosphorus loads that contribute to eutrophication in the coastal zone.
