Overview
Tianjin wastewater treatment plant serves Jinghai District, Tianjin, China, with a population equivalent of 40,000. The facility operates under China's national wastewater discharge standards.
The Tianjin wastewater treatment plant is located in Jinghai District, Tianjin, China, serving a population of approximately 40,000. It is situated in the Tianyu Science and Technology Park area, supporting the local municipal and industrial wastewater management needs. As a medium-sized agglomeration, the plant is expected to meet 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 total phosphorus. The plant's scale suggests it likely employs secondary biological treatment to comply with national standards. The treated effluent is discharged into local waterways that ultimately drain into the Bohai Sea via the Hai River system. The plant plays a crucial role in protecting the aquatic environment of the Hai River basin and reducing nutrient and pollutant loads to the Bohai Sea, a semi-enclosed sea with significant ecological importance.
Environmental context
The plant discharges into the Hai River basin, which flows through Tianjin and empties into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient pollution and eutrophication. The plant's operations help mitigate the impact of urban and industrial wastewater on this ecologically important marine environment, supporting water quality and biodiversity in the region.
Frequently asked questions
The plant is located in Jinghai District, Tianjin, China, specifically in the Tianyu Science and Technology Park area on Ping'an Road.
The plant serves a population equivalent of approximately 40,000 people.
The treated effluent is discharged into local waterways that are part of the Hai River basin, which ultimately flows into the Bohai Sea.
The plant operates under China's national wastewater discharge standards, specifically the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits for pollutants like COD, BOD, and nutrients.
For a medium-sized agglomeration of 40,000 people, secondary biological treatment is typical to meet the national discharge standards, often including nutrient removal to protect sensitive receiving waters.
