| 摘 要： | 采用TiO2悬浮体系光催化氧化处理苯酚模拟废水,利用紫外吸光度表示苯酚相对含量,考察了TiO2用量、pH值、曝气、苯酚浓度、处理时间及光强等因素对苯酚去除率的影响.结果表明:当TiO2用量为2g·L-1、pH值为3、连续曝气和搅拌条件下,在一定光强紫外光照射2.5h,苯酚(10mg·L-1)去除率达96%.

| Abstract: | An investigation into photocatalytic oxidation of phenol in water used as simulated waste-water by titanium dioxide particles was conducted in an experimental matrix of jar tests. The influences of such factors as TiO_2 dosage,initial value of pH,initial concentration of phenol on removal of phenol are studied,respectively.The result indicates that phenol could be removed from water effectively by using photocatalytic oxidation of tianium dioxide suspension,and under certain conditions,the removal rate of phenol could reache 96%. |
