Abstract

The invention discloses a preparation method of macro-porous adsorption resin for treating phenol-containing wastewater. The method comprises the following steps: adding a pore forming agent isooctane, an initiator benzoyl peroxide and a dispersant polyvinyl alcohol into deionized water in order to form an aqueous phase, adding a divinyl benzene framework material having a weight percentage concentration of 85% according to a ratio of the aqueous phase to the framework raw material of 75:25 to 50:50, thoroughly mixing and stirring the aqueous phase and the framework raw material in a reactor,sequentially heating the obtained mixed solution in four stages to perform a suspension polymerization reaction in order to make the mixed solution gradually solidified into milky white spherical particles, expanding the milky white spherical particles with a chloromethylation solvent, performing a reaction under the action of a catalyst, washing and drying the obtained reaction product to obtainchlorine balls, expanding the chlorine balls with an expanding agent, adding a catalyst, performing a reaction, recovering the expanding agent, transferring the obtained chlorine balls into an elutioncolumn, and eluting out the remaining pore forming agent in the chlorine balls. The method has the advantages of low pollution and low production cost, the obtained macro-porous adsorption resin hasgood performances, and the treatment rate is equal to or more than 98% when the macro-porous adsorption resin is used to treat the phenol-containing wastewater.

Description

technical field [0001] The invention relates to an adsorption resin, in particular to a preparation method of an adsorption resin for treating phenol-containing wastewater. Background technique [0002] Various industries that use phenol as raw material or synthesize phenol will produce different quantities and properties of phenol-containing wastewater in the production process. Phenol-containing wastewater will be discharged into water bodies without treatment, which will endanger the reproduction and survival of aquatic organisms. If the water contains 0.1-0.2 mg / L of phenol, the fish will smell of phenol; if it contains 1 mg / L of phenol, it will affect fish spawning and migration; if it contains 5-10 mg / L of phenol, a large number of fish will die. Drinking water contains phenols, which can affect human health. Even if the concentration of phenol is as low as 0.002 mg / L, disinfection with chlorine will produce the stench of chlorophenol. Crops will wither and die if th...
