Overview
Beijing wastewater treatment plant serves 35,000 people in Haidian District, Beijing, China. It operates under China's national wastewater standards for inland facilities.
The Beijing wastewater treatment plant is located in Sujiatuo Town, Haidian District, Beijing, China. It serves a population of approximately 35,000, classifying it as a medium-sized municipal facility within the greater Beijing metropolitan area. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For inland plants like this, Class 1-A or 1-B standards typically apply, requiring biological treatment with nutrient removal. The plant discharges treated effluent into local waterways that ultimately drain into the Hai River system, which flows into the Bohai Sea. Its operation helps protect downstream aquatic ecosystems and supports water quality in the densely populated Beijing region.
Environmental context
The plant's treated effluent enters the Hai River basin, which flows through northern China before reaching the Bohai Sea. This watershed supports diverse aquatic life and provides water for agriculture and industry. The Bohai Sea is a semi-enclosed water body sensitive to nutrient pollution, making effective treatment crucial for coastal ecosystem health.
