Overview
The Hebei wastewater treatment plant serves Tongzhou District, Beijing, China, with a population of 80,000. It operates under China's national wastewater standards, contributing to local water quality management.
The Hebei wastewater treatment plant is located in Tongzhou District, Beijing, China, serving a population of approximately 80,000. The facility is part of the municipal wastewater infrastructure for the region, which is undergoing rapid urbanization and environmental regulation. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to achieve secondary treatment with nutrient removal, especially in sensitive watersheds. Regulatory expectations for agglomerations of this size emphasize compliance with Class 1A or 1B effluent standards. The plant discharges into local waterways that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The Hai River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Effective treatment at this plant helps reduce pollution loads to downstream environments.
Environmental context
The plant's treated effluent enters the local drainage network within the Hai River basin, which flows through Tianjin and discharges into the Bohai Sea. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it sensitive to nutrient and pollutant inputs. The Hai River basin supports important fisheries and migratory bird habitats, and wastewater treatment plays a key role in protecting these ecosystems from eutrophication and contamination.
