| 摘 要： | 采用UV/H2O2/微曝气、UV/H2O2、UV/微曝气、H2O2/微曝气四种工艺处理受苯胺污染的水源水.试验结果表明,采用UV/H2O2/微曝气工艺,H2O2投加量分别为1,2,5,10和20 mL,对苯胺均有理想的去除效果.随着投加量的增加,苯胺的去除率并没有明显的提高,反应30 min后去除率分别达到94.3%,96.4%,96.5%,97.3%和96.8%.原水苯胺为0.90 mg/L时,投加1 mL H2O2反应30 min后,出水苯胺为0.06 mg/L,满足标准要求.UV/H2O2/微曝气、UV/H2O2、UV/微曝气、H2O2/微曝气四种工艺对苯胺的去除率均随着时间的增长而提高,40 min后趋于平稳,最高去除率分别为97.9%,94.5%,64.27%和13.84%,UV/H2O2/微曝气、UV/H2O2出水苯胺均低于规定限值.

| Abstract: | UV/H2O2/micro-aeration,UV/H2O2,UV/micro-aeration and H2O2/micro-aeration processes were tested for the treatment of raw water with aniline.H2O2 were dosed at 1,2,5,10 and 20 mg/L respectively in the UV/H2O2/micro-aeration process.The result showed that relative satisfied removal efficiency could be obtained,and the removal rate of aniline did not improve significantly when the dose increased.The removal rate could reach 94.3%,96.4%,96.5%,97.3% and 96.8% after reaction for 30 minutes.The aniline in the efflu... |
