摘要
针对不同的过氧化氢加入量、反应体系的pH值、温度和反应时间等因素对废水中苯酚去除率的影响进行了研究。结果表明:在过氧化氢/活性炭体系中,在反应体系pH值为3.0左右,反应时间在20 min左右,一定的范围内,少量的H_2O_2加入量对苯酚的去除率有较好的效果。废水中苯酚的去除效果为:过氧化氢/活性炭体系>活性炭>过氧化氢。
In this paper, the effect of hydrogen peroxide/activated carbon system with differ-ent factors such as hydrogen peroxide content, reaction pH value, temperature and, reaction time on the removal efficiency of phenol in wastewater was presented. It is shown that with a pH value of 3.0, reaction time of 20 minutes and a little hydrogen peroxide added in a cer-tain range, the system will be very effective to the removal of phenol. The effectiveness for the removal of phenol in wastewater with different approaches is compared as follows： hydrogen peroxide/activated carbon system〉activated carbon〉hydrogen peroxide.
