| As foundational organic raw material and the most important organic solvent, methyl alcohol, acetone, THF. etc. are widely used in the fields of organic synthesizing, pharmacy and organic synthesizing of macromolecule etc. At the production and applying process, a great deal of wastewater was discarded to the environment, which not only result in serious pollution but also the resources waste. Therefore how to treatment economically and efficiently is one of the important missions. Our work are research on those kinds of wastewater treatment and recycling by macroporous adsorption resins , which has not been reported.Under the static and dynamic conditions, the adsorption processes have been studied for adsorbing low carbon alcohols, aldehyde, acetone and acetic acid in aqueous solution with XDA series Friedel-Crafs backcrosslinked macroporous adsorption resins. A new technique, named unification of adsorption and distillation, was studied for the recycling of resins adsorbed organic compounds with low boiling point.According to the alike -compatible principle, grouped for the relativity between adsorption ability of organic compounds on resin and organic compound's moleculestructure were discussed. Put forward the indexes of depicting adsorption ability of different organic compounds on resins.The results showed that the macroporous XDA series adsorption resins can adsorb low carbon alcohols, aldehyde, acetone and acetic acid very will. Within 4 hours , the adsorption process could reach equilibrium . The static adsorption process of alcohols and acetone both obeyed Freundlich equations and Langmuir equations. Dynamic adsorption efficiency is 90-98%, the range of breakthrough volume is 1-7BV. Increasing the concentration of organic compounds and decreasing the velocity of flow could enhance the adsorption capacity.The result of organic compounds distilling experiments showed that the recycling efficiency of distilling resins within oil-tub, was approximate to that of directly distillation of low concentration solution, and was about 80-93%. But the distill volume was much less than that of the adsorption volume by resins and the distill time could be decreased a lot. At the condition that the vapor of water distilled with outside cycle hot water and condensed with ice water, the total recycling efficiency reached 85%, which could decrease the distill losing to a very low point.The experiments proved that the hydrophobic-hydrophilic ratio could depict the adsorption ability of resins to the homologous series organic compounds. Non-polarity fraction of organic compounds has great relativity with the resin's adsorption capacity. So it could be used as the index of adsorption capacity of non-polarity XDA series resins to the organic compounds in experiments.The main innovations of the research work included:1 .The systematically study the static and dynamic adsorption properties and reclaimprocess of water-soluble low carbon alcohols, aldehyde, acetone and acetic acid onXDA series macroporous adsorption resins, which have not been reported in thepresent data.2.Putting forward the resin adsorb-distill unification craft, which can improvereclaim efficiency and decrease resin regeneration cost.3. Grouping the relativity between adsorption ability of organic compounds onresins and the molecule structure of organic compounds; Putting forward the indexof depicting the adsorption ability of different organic compounds on resins.
