Beijing Wastewater Treatment Plant, Fengtai District, Beijing, China

The Beijing wastewater treatment plant is located in Fengtai District, Beijing, China, serving a population of approximately 22,000. The facility is part of the municipal wastewater infrastructure managed by local authorities, contributing to the city's sanitation and water quality management. As a plant serving a medium-sized agglomeration, it is expected to meet secondary treatment standards under China's national wastewater discharge regulations. The facility's operational context aligns with the country's Water Pollution Prevention and Control Law, which mandates treatment levels based on receiving water body sensitivity and population scale. The plant discharges treated effluent into local water bodies that ultimately drain into the Hai River system, which flows into the Bohai Sea. This downstream connection underscores the plant's role in protecting both local aquatic ecosystems and the broader marine environment from nutrient and pollutant loads.

The plant's treated effluent enters the local drainage network within the Hai River basin, which flows through northern China before discharging into the Bohai Sea. The downstream environment supports diverse aquatic life and is ecologically sensitive to nutrient enrichment. Effective treatment at this facility helps mitigate impacts on the riverine and coastal ecosystems.
