摘　　要：采用连续流试验,研究了羟基化锌(ZnOOH)催化臭氧氧化和单独臭氧氧化去除水中痕量卡马西平(CBZ)的效果,并探讨了臭氧投加量、pH值、催化剂投加量及使用次数等因素对催化性能的影响。结果表明,ZnOOH对水中的CBZ有较强的催化活性,相同试验条件下,催化臭氧氧化出水中的CBZ浓度比单独臭氧氧化的低48.5%,且对CBZ的去除效果随催化剂投加量的增加而提高。本试验条件下,催化剂的最佳投加量为100 mg/L;催化剂在偏碱性条件下对目标物的去除效果更佳;催化剂使用了5次,其催化效果基本没有变化,没有发现锌离子溶出。The effects of catalytic ozonation with supported ZnOOH and ozonation alone on removal of carbamazepine （CBZ） in water were investigated in a continuous flow reactor. The influences of O3 dose, pH, catalyst dose and catalyst reuse on the CBZ removal were examined. Experimental results showed that ZnOOH had excellent catalytic activity in CBZ ozonation. The concentration of CBZ in the treated water by catalytic ozonation with supported ZnOOH was 48.5% less than that by ozonation alone in the same conditions. CBZ removal was improved with increasing of catalyst dosage. The optimal catalyst dosage was 100 mg/L in this experiment. The optimal catalytic activity of ZnOOH was achieved under weak basic condition. The catalyst was used five times without significant deterioration of activity, and no dissolution of zinc ions was observed.
