【摘要】 采用微波诱导ClO2催化氧化工艺技术,以改性氧化铝为催化剂,对模拟苯酚废水进行了处理。优化了处理工艺条件,实验在固液质量比为1:20(100mL苯酚水溶液中投加5．0g改性氧化铝)、投加1％的ClO2溶液0．8mL、微波功率为50W辐照5min的处理条件下,对水中苯酚的去处率可达到92．24％,COD去除率为79．1 3％。通过对比实验和验证实验进一步研究表明在微波辐射场中废水中的有机污染物在改性氧化铝表面通过催化和氧化协同作用而被迅速降解。实验结果显示,微波诱导ClO2催化氧化工艺比微波诱导ClO2氧化工艺、水浴加热ClO2催化氧化工艺和水浴加热ClO2氧化工艺有更好的处理效果,且较传统ClO2氧化工艺和ClO2催化氧化工艺大大缩短了反应时间、提高了氧化剂的氧化效率,并且反应条件比较温和。更多还原

【Abstract】 phenol waste water was treated by microwave- induced CIO2 catalytic oxidation process(MIOP) with modified Al2O3 as a catalyst . Under the optimum condition that the solid/liquid ratio was 1 20(5.0g modified Al2O3 mixed with 100mL phenol 50 % solution) , microwave power was 50W, and the time of the irradiation was 5 min , the phenol removal rate could come up to 92.24% and COD removal rate reached up to 79.13 %. The catalyst could be reused more than 9 times remaining the high rate of the dye removal . Through contrastive experiment and further investigation showed that phenol was degraded by microwave on the surface of catalyst with the chemical reaction mechanism of catalytic reaction and microwave induced oxidation. The result showed that microwave- induced ClO2 catalytic oxidation process(MIOP) had more better effect of treatment than microwave- induced ClO2 oxidation process , ClO2 catalytic oxidation process in 47 bath and ClO2 oxidation process in 47 bath.MIOP greatly shortened reaction time, improved oxidation efficiency of oxidant, and reaction condition was very kindly.更多还原
