The invention discloses a cationic selective sewage treatment flocculant and a preparation method and application thereof, and relates to the technical field of sewage treatment.The method comprises the steps that firstly, acrylamide, sodium alginate, sodium isethionate and reduced graphene oxide are mixed and dissolved to synthesize a precursor; then ammonium persulfate, N, N '-methylene bisacrylamide and N, N, N', N '-tetramethylethylenediamine are added, and a hydrogel material is prepared through a free radical polymerization method; finally, the prepared hydrogel material is dried and ground into powder, and the multifunctional flocculant material for heavy metal cation adsorption, microbiological treatment and purification and sewage solid particle adsorption is obtained. The preparation method is convenient and efficient, the application mode is simple, the treatment effect is obvious, and treated sewage can reach the sanitary standard of domestic water. 本发明公开了一种阳离子选择性污水处理絮凝剂及其制备方法和应用，涉及污水处理技术领域，该方法首先使
