Overview
Beijing wastewater treatment plant serves Daxing District with a population equivalent of 120,000. Located in the Chinese capital, it operates under national environmental regulations.
The Beijing wastewater treatment plant is situated in Daxing District, a suburban area of China's capital city. Serving a population equivalent of 120,000, it is a medium-sized municipal facility within the broader Beijing wastewater infrastructure. The plant is part of China's extensive urban wastewater treatment network, which has expanded rapidly to meet the demands of urbanization and environmental protection. Under China's Water Pollution Prevention and Control Law, municipal wastewater treatment plants are required to meet discharge standards that align with the receiving water body's classification. For facilities serving populations over 100,000, advanced treatment (tertiary) is often mandated to reduce nutrients and protect water quality. The plant's treatment processes and capacity are designed to comply with these national standards, though specific operational details are not publicly available. The plant discharges treated effluent into local waterways that eventually flow into the Hai River system, which drains into the Bohai Sea. This coastal sea is ecologically sensitive, supporting fisheries and marine biodiversity. The plant plays a crucial role in reducing pollutant loads to the river and sea, helping to mitigate eutrophication and protect downstream aquatic ecosystems.
Environmental context
The plant's treated effluent enters the local drainage network, which feeds into the Yongding River, a major tributary of the Hai River system. The Hai River flows through the North China Plain and discharges into the Bohai Sea, a semi-enclosed sea with limited water exchange. The Bohai Sea supports important fisheries and migratory bird habitats, making nutrient and pollutant control critical to preventing algal blooms and maintaining ecological balance.
Frequently asked questions
The plant is located in Daxing District, Beijing, China, specifically near the Xicheng District Second Detention Center on Huangma Road.
The plant serves a population equivalent of 120,000 people in the Daxing District area.
Treated effluent is discharged into local waterways that flow into the Yongding River, part of the Hai River system, ultimately reaching the Bohai Sea.
The plant operates under China's Water Pollution Prevention and Control Law, which sets discharge standards based on receiving water body classifications. For plants serving over 100,000 people, advanced treatment is typically required.
In China, municipal plants serving populations over 100,000 are generally required to achieve tertiary treatment to meet stringent nutrient removal standards, especially when discharging into sensitive water bodies like the Hai River and Bohai Sea.
