Beijing Wastewater Treatment Plant, Daxing District | Serving 120,000 People

The Beijing wastewater treatment plant is located in Daxing District, Beijing, China, serving a population of 120,000. It is situated near the Liangshui River greenway in the Yizhuang area, a rapidly developing district known for its advanced autonomous driving demonstration zone. The plant is part of Beijing's extensive municipal wastewater infrastructure, which manages the city's growing water treatment needs. As a plant serving a medium-sized agglomeration, it operates under China's national wastewater discharge standards, which are aligned with the country's Water Pollution Prevention and Control Action Plan. These regulations mandate secondary treatment as a minimum for urban wastewater, with stricter limits for sensitive water bodies. The plant's treatment processes are designed to meet these standards, ensuring compliance with local environmental requirements. The treated effluent is discharged into the Liangshui River, which flows into the Hai River system and ultimately reaches the Bohai Sea. This river is an important waterway in the Beijing region, supporting local ecosystems and agricultural activities. The plant plays a crucial role in protecting the water quality of the Liangshui River and downstream environments, contributing to the ecological health of the Hai River basin.

The plant discharges into the Liangshui River, a tributary of the Hai River system, which flows into the Bohai Sea. The Hai River basin is a densely populated and industrialized region, facing challenges from agricultural runoff and urban pollution. The plant's operations help reduce nutrient and pollutant loads, protecting downstream aquatic habitats and supporting biodiversity in the Bohai Sea coastal zone.
