The invention relates to a modified macroporous adsorption resin, and a preparation method and application thereof. The preparation method of the modified macroporous adsorption resin comprises the following steps: obtaining macroporous adsorption resin, wherein the surface of the macroporous adsorption resin contains double bonds; and mixing water, an oxidizing agent and the macroporous adsorption resin, and carrying out one-step oxidation reaction to oxidize the double bonds into hydroxyl groups, wherein the oxidizing agent is a combination of sulfuric acid and peracetic acid, or pypocholoride, periodate, or a combination of hydrogen peroxide and peracetic acid, the pypocholoride is at least one of sodium hypochlorite, potassium hypochlorite and calcium hypochlorite, and the periodate is at least one of sodium periodate and potassium periodate. According to the preparation method of the modified macroporous adsorption resin, hydrophilic modification of the macroporous adsorption resin can be achieved throug
