Overview
Tianjin wastewater treatment plant serves Beichen District, Tianjin, China, with a population equivalent of 100,000. The facility operates under China's national wastewater discharge standards.
The Tianjin wastewater treatment plant is located in Beichen District, Tianjin, China, serving a population equivalent of approximately 100,000. It is part of the municipal wastewater infrastructure for the greater Tianjin metropolitan area, a major industrial and port city in northern China. As a plant serving a medium-sized agglomeration, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and phosphorus. Treatment typically includes biological processes with nutrient removal to meet these standards. The plant discharges treated effluent into local waterways that ultimately drain into the Hai River system, which flows into the Bohai Sea. The Bohai Sea is a semi-enclosed water body with significant ecological and economic importance, supporting fisheries and maritime activities. Proper treatment is crucial to prevent eutrophication and protect marine ecosystems.
Environmental context
The plant's treated effluent enters the Hai River basin, which flows through Tianjin and discharges into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient pollution from urban and industrial sources. Effective wastewater treatment is essential to reduce nitrogen and phosphorus loads that can cause algal blooms and hypoxia in coastal waters.
