| 中文摘要: |
| 以1．0g苯酚溶于1000mL无酚水中作为高浓度的有机物模拟水样组成反应模型，在微波辐射下研究了H2O2综合反应体系H2O2／TiO2；H2O2／Fe^2＋；H2O2／活性炭；H2O2，Fe^2＋／活性炭对水中高浓度苯酚的降解作用，实验测量了H2O2在不同体系中的分解速率，并测量苯酚在这些体系中的分解速率和有机物耗氧量（CODCr）去除率，实验表明H2O2所在体系的分解速率和苯酚的分解速率依次为H2O2，Fe^2＋／活性炭〉H2O2／Fe^2＋〉H2O2／活性炭〉H2O2／TiO2，而体系H2O2／活性炭由于活性炭在微波辐射下有较强的氧化协同作用，该体系对有机物COD呈现出很高的去除率。 |

| Taking,as a model,the waste water composed of 1.0 g phenol in 1 000 mL solution,the study investigated the effect of the H_2O_2 reaction systems that can be composed respectively by H_2O_2/TiO_2;H_2O_2/Fe~(2+);H_2O_2/activated charcoal;H_2O_2,Fe~(2+)/ activated charcoal on the degradation of phenol in water under microwave radiation,determined the decomposition rate of H_2O_2 and phenol in these systems,and measured COD_(Cr) in water.Results show the decomposition rate of H_2O_2 and phenol in these systems is H_2O_2,Fe~(2+)/ activated charcoal>H_2O_2/Fe~(2+)>H_2O_2/ activated charcoal>H_2O_2/TiO_2 respectively.COD in H_2O_2/ activated charcoal systems show a high removal ratio as activated charcoal assisted reaction under microwave radiation. |
