    The experimental results and thermodyamic analysis on the treatmentof poisonous and biological undegraded coking waste water with activatedcarbon adsorption method had been reported in the paper (Ⅰ).In orderto reuse the activated carbon efficiently,authors have developed a newregeneration method—wet catalyticoxidation.A most effective catalystis chosen,and the optimal regeneration conditions are determined.Afterregeneration for five times,the average efficiency is 64.4 percent.

    文(一)[1]中已阐述用活性炭吸附法处理焦化废水中有机毒物的结果及热力学分析。为了使活性炭得到有效利用,作者研究了一种新的活性炭再生方法—湿式催化氧化,选出了较有效的催化剂,确定了最佳再生条件。活性炭经五次再生,其平均再生率为64.4%。

    A method of oxidizing nonbiodegradable and toxic organic substances in coking waste water with Fenton reagent(H2O2 + Fe2+)in presence of ultraviolet(UV)radiation is studied. The results indicate that this method has stronger disintegrating ability to all toxic organic substances, including polycyclic aromatic hydrocarbons(PAH). However, how to reduce the treatment costs needs further work.
