The invention relates to the technical field of desulfurization wastewater treatment, in particular to a preparation device and a preparation method of a composite flocculant. The preparation device comprises a main material preparation tank, a coagulant aid preparation tank, an acid storage tank, an alkaline storage tank and a plurality of auxiliary material preparation tanks, wherein the acid storage tank, the alkaline storage tank and all the auxiliary material preparation tanks are communicated with the main material preparation tank; the main material preparation tank and the coagulant aid preparation tank are both communicated with the coagulating basin. According to the device, the preparation process of the composite flocculant is simplified, and the composite flocculant with the required concentration can be continuously and quantitatively provided for wastewater treatment equipment. Besides, the composite flocculant prepared by the method is used under an acidic condition and can settle suspended ma
