The present invention relates to the field of water treatment, and disclosed are a preparation method for a polyamino three-dimensional graphene porous aerogel and a use thereof. The preparation method comprises: (1) dissolving a water-soluble polymerizable monomer, an initiator, and a cross-linking agent in water to obtain an aqueous phase reaction solution; (2) dispersing a hydroxyl group-containing graphene oxide and hydroxyl group-containing single layer thin wall carbon nanotubes in the aqueous phase reaction solution; (3) injecting same into a mold and performing free radical polymerization to obtain a hydrogel; (4) carrying out freeze drying to obtain a porous aerogel containing three-dimensional graphene; (5) sequentially carrying out Michael addition and condensation polymerization on a polyamine and methyl acrylate to obtain a polyamino hyperbranched polymer; and (6) utilizing the polyamino hyperbranched polymer to carry out a grafting reaction on the porous aerogel containing the three-dimensional
