Non-ferrous metallurgical wastewater has high concentrations and complex pollutants, which must be effectively treated before discharge. The bioreactor is a commonly used non-ferrous metallurgical wastewater treatment equipment, but the research progress of different reactors lacks a summary and comparison. This review of bioreactors is pointed out by bibliometric analysis, and it is ascertained that bioreactor is one of the hot technologies in the future. In addition, the three representative bioreactors membrane bioreactor (MBR), moving bed biofilm reactor (MBBR) and biological filter (BF) are systematically reviewed and compared, and their respective applicable scenarios, strengthening measures and future research directions are proposed. This study systematically summarizes the research characteristics of MBBR, MBR and BF, and provides a reference for selecting devices to treat non-ferrous metallurgical wastewater.
