Dongpai river ecology restoration project

The treatment section of the Dongpai discharge basin in Tianjin Economic and Technological Development Zone has a length of 2.3 km and a width of 25m - 40m. The discharge basin contains a high salinity due to seawater intrusion making conventional biological treatment extremely difficult and pollution from 4 pumping stations and a wastewater treatment plant that directly discharge collected stormwater and tailwater into the basin.

Describe

The treatment section of the Dongpai discharge basin in Tianjin Economic and Technological Development Zone has a length of 2.3 km and a width of 25m - 40m. The discharge basin contains a high salinity due to seawater intrusion making conventional biological treatment extremely difficult and pollution from 4 pumping stations and a wastewater treatment plant that directly discharge collected stormwater and tailwater into the basin. The water quality was inferior to class 5 of the national surface water standard due to the pollutions.

Since the installation of the MABR system in May of 2020, the water quality at the East discharge open channel has been stable and improved to Class III of the national surface water standard.
