| 摘 要： | 采用连续流试验,研究了负载型羟基氧化铁(FeOOH)催化臭氧氧化和单独臭氧氧化控制三卤甲烷生成势(THMFP)的效果.结果表明,负载型羟基氧化铁催化臭氧氧化出水中的THMFP比单独臭氧氧化的低22%.这主要和催化氧化对TOC的去除率较高以及羟基自由基破坏卤代活性位的能力较强有关.在不同的臭氧投量、溴离子浓度及接触氧化的停留时间下,负载型FeOOH催化氧化都表现出了更好的控制THMFP的效果.随着臭氧投量的增加,催化臭氧氧化出水中的THMFP先升高后降低,但都比单独臭氧氧化出水的THMFP要低.溴离子浓度较高时THMs以溴代产物为主,催化氧化控制THMFP的优势相对更明显.延长接触氧化反应的停留时间可使催化臭氧氧化出水的THMFP进一步降低.

| Abstract: | The effects of catalytic ozonation with supported ferric hydroxide(FeOOH)and ozonation alone on trihalomethane formation potential(THMFP)were investigated in a continuous flow reactor.The THMFP of the treated water by catalytic ozonation with supported FeOOH is 22% less than that by ozonation alone.It is related to the higher TOC reduction and higher reactivity of hydroxyl radical during catalytic ozonation with supported FeOOH.Under the conditions of different ozone dosages,bromide concentrations and conta... |
