Description
Technical field
The present invention relates to a kind of use in waste water treatment macroporous absorbent resin, especially a kind of macroporous absorbent resin of handling phenol and aniline in the industrial discharge organic wastewater and preparation method thereof belongs to chemical field.
Background technology
Macroporous absorbent resin just begins industrialization as a kind of parting material as far back as the sixties.Because the development that environmental protection in recent years and Chinese medicine separate, macroporous absorbent resin rely on its advantage to obtain once more using widely:
(1) scope of application is wide, and applicability is good.Organic concentration mg/L from several to up to ten thousand all can handle in the waste water, and adsorption effect is not subjected to the influence of contained inorganic salts in the solution.
(2) specific area is big, the adsorption efficiency height, and desorption and regeneration is easy.Macroreticular resin can reach more than 99% usually to organic adsorption rate, does not produce secondary pollution.Desorb soda acid commonly used or organic solvent, desorption efficiency generally can reach more than 95%.
(3) resin property is stable, long service life.Resin has the performance of higher resistance to oxidation, acid and alkali-resistance, organic solvent-resistant, can use for a long time below 150 ℃, and under normal circumstances year proportion of goods damageds are less than 5%.
(4) help the comprehensive regulation, turn waste into wealth.Adopt resin adsorption can recycle pollutant, cut down expenses, increase benefit.
(5) technology is simple, does not need special installation, and technology is grasped easily, and is easy to operate, and operating cost is lower.Because the development aspect the organic industrial sewage of handling high concentration, difficult degradation of above these characteristics, polymeric adsorbent especially at aspects such as phenols, amine, organic acid, nitro thing, halogenated hydrocarbons, makes substantial progress rapidly.
Phenol is a kind of pollutant of severe toxicity, and its discharge capacity occupies the organic pollution prostatitis.Aniline has severe toxicity, can and cause poisoning through skin, respiratory tract and alimentary canal absorption, the long-term contact with aniline can cause liver cancer or wing skin cancer, also can cause the human body acute poisoning, produce headache, dizzy, decrease of memory, unsmooth breath, even symptom such as death by suffocation.Usefulness XN-1 type macroporous absorbent resin Pyrogentisinic Acids such as Li Ensi adsorb research (Li Ensi, the Sichuan environment, 1995.14.1); Usefulness XAD-2 type macroreticular resin Pyrogentisinic Acids such as Liu Yiqun have carried out absorption research, and study its dynamics (Liu Yiqun, water technology, 1989.15.4); Honest and clean wait quietly to macroporous resin adsorption aniline done systematic research (Lian Jing. the academic dissertation .2004 of Institutes Of Technology Of Nanjing); Zhang Quanxing, Chen Jinlong etc. handle organic wastewater to macroporous absorbent resin and have done a large amount of work.But not at phenol and the synthetic a kind of macroporous absorbent resin that can adsorb pollutant fast and in a large number of aniline.And there are the Pyrogentisinic Acid in existing phenol and the special-purpose macroporous absorbent resin of aniline absorption, the phenol adsorbance is low, the lower waste water treatment efficiency that causes of the rate of adsorption is not high, processing cost is crossed high shortcoming.
Summary of the invention
