The invention relates to flocculating agent blending equipment, in particular to efficient blending equipment for flocculating agents used for sewage treatment. The technical effect that the efficient blending equipment for flocculating agents used for sewage treatment which is uniform in blending, high in blending speed and simple in structure is provided is achieved. In order to achieve the technical effect, the provided efficient blending equipment for s flocculating agents used for sewage treatment comprise a first electronic control valve, a discharging pipe, a small belt pulley, a first rotary shaft, a first bearing seat, a first mounting base, an electric push rod, a second mounting base, a cam, a left frame and the like. The left frame is welded to the left end of the top of a bottom plate. The first mounting base and a support are welded to the left side of the top of the bottom plate. The first mounting base is located on the left side of the support. The efficient blending equipment for the flocculating agents achieves the effects of uniform blending, high blending speed and simple structure, the important functions played by the equipment comprise the good blending effect and the improvement of working efficiency, and the safety is high.
