| 摘 要： | 利用TiO2/ACF,以主波长为254 nm的紫外灯为光源,光催化氧化反应器内的苯酚溶液,考察了动态条件下苯酚的去除效果.结果表明：设计、制作的光催化氧化反应器优化了水力条件,强化了光源利用;在动态条件下,TiO2/ACF光催化氧化去除苯酚主要影响因素有溶液pH、光强、废水流速、水力停留时间（HRT）、通氧条件等.在苯酚初始浓度为40 mg/L,废水pH=7.5,反应器内紫外灯光强为1.75 W/L,起搅拌、充氧作用的空气量Q=2.6 mL/（min·L）,苯酚废水流量为0.05 L/min,即废水在反应器中的HRT约为7.67 h时,苯酚去除率可达91%,COD去除率约为79%.
