Abstract：

In this study, the water quality of Haitai North-South Street Landscape River was evaluated to be eutrophication and the water quality was worse than the surface water environmental quality standard (GB3838-2002) V. The increase of nitrogen and phosphorus content was the main factor that causing the river water blooms. Aiming at the existing problem, membrane aerated biofilm reactor (MABR) bioremediation solution was put forward. Aquatic plants type MABR membrane component and water body bioremediation system were designed. Afterwards, the MABR system was continuously operated and monitored for 5 months. The results indicated that the MABR bioremediation system significantly improved the self-purification capacity of Haitai North-South Street Landscape River. In the treated river water, the NH3-N, COD and TP concentrations met the surface water environmental quality standard (GB3838-2002) III or IV and the TN concentration met the surface water environmental quality standard (GB3838-2002) V. The algal bloom was not observed in the entire operating period. Thus, MABR technology has wide application prospect in river water bioremediation.
