Problems solved by technology

[0006] However, in the prior art, there is no macroporous adsorption resin that can quickly and massively adsorb pollutants for sewage mixed with strong water-soluble organic substances such as nitrobenzene and phenol.
However, due to the low polarity of the existing macroporous adsorption resins for the adsorption of nitrobenzene and aniline, there are waste water treatment problems caused by low adsorption capacity and slow adsorption rate of mixed strong water-soluble organic pollutants such as p-nitrobenzene and phenol. Disadvantages such as low efficiency and high processing cost

Abstract

The invention relates to a strong-polarity macroporous adsorption resin belonging to the technical field of high-polymer macroporous adsorption resin. The strong-polarity macroporous adsorption resin comprises the following components by weight parts: 10-30 parts of divinyl benzene taken as an oil phase, 10-20 parts of trimethylolpropane triallyl ester, 10-20 parts of trimethylolpropane trimethylacrylate, 20-40 parts of acrylonitrile, 5-10 parts of methyl acrylate, 5-10 parts of styrene, 50-150 parts of pore-foaming agent, 0.5-1 part of 2, 2-azobisisobutyronitrile (AIBN), and 300-500 parts of distilled water taken as an aqueous phase, 5-15 parts of polyvinyl acetate (PVA) and 20-50 parts of NaCl. The strong-polarity macroporous adsorption resin is synthesized and prepared, and high-water-solubility nitrobenzene, phenol and other organic matters can be effectively adsorbed in the process of treating organic wastewater.

Description

technical field [0001] The present invention relates to a kind of strongly polar macroporous adsorption resin, more specifically, the present invention relates to a kind of strong polar macroporous adsorption resin for treating strong water-soluble organic matter in industrial discharged organic waste water, which belongs to macromolecular material macroporous adsorption resin technology field. Background technique [0002] As a polymer adsorbent, macroporous adsorption resin has been widely used in various fields since it was developed and applied in the 1960s. In the past 20 years, due to its excellent adsorption performance and renewable performance, it has been better applied in the field of environmental protection, especially in the adsorption and recovery of water-soluble toxic organic substances in industrial wastewater. Macroporous adsorption resin is a polymer synthetic adsorbent with porous and large specific surface area. Its mechanism of action is physical adso...
