Overview
Tianjin wastewater treatment plant serves 200,000 people in Binhai New Area, Tianjin, China. It operates under China's national wastewater discharge standards.
The Tianjin wastewater treatment plant is located in Dagang Subdistrict, Binhai New Area, Tianjin, China. It serves a population of 200,000, placing it in the large agglomeration category for Chinese municipal wastewater infrastructure. The plant is situated in a coastal industrial region near the Bohai Sea. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline, with tertiary treatment often mandated for sensitive receiving waters. For a plant of this scale, compliance with Class 1A or 1B effluent standards is typical, depending on the environmental sensitivity of the receiving water body. The plant's treated effluent ultimately drains into the Bohai Sea via local waterways. The Bohai Sea is a semi-enclosed marginal sea that supports diverse marine life and is an important fishing ground. The region faces environmental pressures from industrial and urban runoff, making effective wastewater treatment critical for protecting coastal water quality and aquatic ecosystems.
Environmental context
The plant discharges into the local river network that flows into the Bohai Sea, a semi-enclosed sea with limited water exchange. The Bohai Sea supports important fisheries and marine biodiversity, including migratory fish and crustaceans. Effective treatment is essential to prevent eutrophication and protect the sea's ecological health, especially given the industrial and urban pressures in the region.
Frequently asked questions
The plant is located in Dagang Subdistrict, Binhai New Area, Tianjin, China, near the coast of the Bohai Sea.
The plant serves approximately 200,000 people, classifying it as a large municipal wastewater treatment facility.
Treated effluent from the plant is discharged into local waterways that eventually flow into the Bohai Sea, a semi-enclosed marginal sea.
The plant operates under China's national wastewater discharge standards, specifically GB 18918-2002, which sets effluent limits for pollutants based on the sensitivity of the receiving water body.
For a large agglomeration in China, secondary treatment is the minimum requirement, and tertiary treatment is often implemented to meet stricter discharge standards, especially when discharging into sensitive coastal waters like the Bohai Sea.
