description The invention discloses an amino resin palladium-loaded nano catalytic material, a preparation method and a method for reducing and removing selenate in water by using the amino resin palladium-loaded nano catalytic material, and belongs to the technical field of wastewater treatment. A base body of the nano catalytic material is chloromethylated polystyrene-divinylbenzene copolymer (namely chlorine balls), and the nano catalytic material is obtained by further grafting reductive amino groups and loading nano zero-valent palladium. The wastewater treatment method comprises the following steps: (1) filtering selenate-containing wastewater, and adjusting the pH value of filtrate; (2) enabling the filtrate to pass through an adsorption tower filled with an amino resin palladium-loaded nano catalytic material, so as to obtain a purified water body; and (3) when a leakage point is reached, eluting and regenerating the nano catalytic material for recycling. According to the method disclosed by the invention, the se
