【摘要】 研究了在降解含氯苯废水的过程中 ,超声波分别与 H2 O2 、O2 、空气联用对氯苯降解效率的影响。结果表明 ,超声波分别与 H2 O2 、O2 、空气联用比单独使用超声波降解效率分别提高 40、3 0、18个百分点。并且随 H2 O2 用量的增加 ,降解效率明显升高。对于 O2 、空气 ,当气体流量小于 0 .3 75 4m L /s时 ,降解效率随 O2 、空气流量的增大而明显升高。更多还原

【Abstract】 The effects of ultrasonic cooperation with hydrogen dioxide(H\-2O\-2)?oxygen(O\-2) or air on the degradation efficiency of chlorobenzene in wastewater were studied.The results showed that through the cooperation of ultrasonic with H\-2O\-2?O\-2 or air,the degradation efficiency of chlorobenzene increased by 40%?30% and 18% respectively compared with using ultrasonic alone.With the increase in H\-2O\-2 quantity, the degradation efficiency was increased apparently. So far as O\-2 and air were concerned, when the flow velocity of gas was not so much as 0.3754 mL/s, the degradation efficiency would make a sharp increase with the flow velocity of gas increased.\;更多还原
