Overview
Tianjin wastewater treatment plant serves 80,000 people in Binhai New Area, Tianjin, China. It has a designed capacity of 1.00 unit, operating under China's national wastewater standards.
The Tianjin wastewater treatment plant is located in Binhai New Area, a coastal district of Tianjin, China. It serves a population of approximately 80,000, placing it in the medium agglomeration category. The plant is part of the municipal infrastructure for the greater Tianjin metropolitan area, one of China's largest industrial and port cities. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater. For plants serving populations around 80,000, compliance with Class 1A or 1B effluent standards is typical, requiring biological treatment and nutrient removal. The designed capacity of 1.00 unit suggests a moderate-scale facility. The plant discharges treated effluent into local waterways that ultimately drain into the Bohai Sea, a semi-enclosed marginal sea with significant ecological importance. The Bohai Sea supports diverse marine life and is a critical fishing ground, but faces pressures from industrial and urban runoff. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting coastal water quality and marine ecosystems.
Environmental context
The plant's treated effluent flows into the Hai River system, which drains into the Bohai Sea via the Bohai Bay. The Bohai Sea is a shallow, semi-enclosed sea with limited water exchange, making it sensitive to nutrient enrichment and pollution. The region supports important fisheries and migratory bird habitats along the East Asian-Australasian Flyway. Effective wastewater treatment is crucial to mitigate eutrophication and protect coastal biodiversity.
Frequently asked questions
The plant is located in Binhai New Area, Tianjin, China, specifically at Xinye 10th Street, Beitang Subdistrict.
The plant serves approximately 80,000 people, classifying it as a medium-sized municipal facility.
Treated effluent is discharged into local waterways that flow into the Hai River system and ultimately the Bohai Sea.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for COD, BOD, ammonia, and phosphorus. For plants serving 80,000 people, Class 1A or 1B standards typically apply.
For medium-sized agglomerations in China, secondary biological treatment with nutrient removal (e. g. , A2O or oxidation ditch) is standard, often followed by disinfection to meet Class 1A standards.
