Abstract

The invention relates to macroporous adsorbent resin for treating phenol-containing industrial wastewater and a preparation method of the macroporous adsorbent resin and belongs to the technical field of the macroporous adsorbent resin. The macroporous adsorbent resin is characterized in that according to physical and chemical properties of a phenol compound, polymer molecular design is adopted, and styrene is selected as a main copolymer monomer; divinyl benzene is used as a main crosslinking agent and matched with glycol dimethacrylate with certain polarity to serve as a second crosslinking agent; moreover, acrylonitrile is used as a fourth monomer, so that the mechanical strength of macroporous resin is enhanced and the service life of the macroporous resin is prolonged; on the basis, a good solvent and a poor solvent are selected to be matched to serve as a pore forming system; the macroporous adsorbent resin which has better adsorption selectivity and higher adsorbing capacity to phenol, and is easy to dilute and long in service life is synthetized by applying a suspension polymerization process in one step; the adsorbing capacity of the macroporous adsorbent resin to the phenol can reach 50 to 60mg / g, and the service cycle is 100 or above.

Description

technical field [0001] The invention relates to a macroporous adsorption resin for treating waste water and a preparation method thereof, more specifically, the present invention relates to a macroporous adsorption resin for treating phenol-containing industrial wastewater and a preparation method thereof, belonging to macroporous adsorption Resin technology field. Background technique [0002] With the rapid development of the chemical industry, a large number of toxic and harmful organic compounds have entered the water environment, causing serious harm to human drinking water. According to statistics, the amount of wastewater discharged by the chemical industry in 2006 accounted for more than 20% of the total industrial wastewater discharge in the country, ranking first, among which the discharge of phenol, aniline and other toxic and harmful organic substances accounted for the second largest amount of wastewater discharged by the chemical industry one. Phenol is an im...
