A cyclically moving carrier biofilm reactor

The utility model relates to a circulating moving carrier biological membrane reactor which comprises a primary sedimentation tank, a liquid outlet of the primary sedimentation tank is sequentially communicated with a peristaltic pump and a feed inlet in the bottom of a reaction tank through pipelines, the interior of the reaction tank is divided into a fall-back area, a lifting area and a settling area, and the fall-back area and the lifting area are separated by a guide plate. The lifting area and the settling area are separated by an overflow plate; and suspended magnetic fillers are placedin the falling-back area and the lifting area. The suspended magnetic filler disclosed by the utility model can increase the dissolved oxygen concentration of a system, induce biological enzyme synthesis and enzyme activity, improve the adsorption and degradation capacities of a carrier on magnetic microorganisms and organic pollutants, and is beneficial to biofilm formation and accumulation of high-concentration microor
