O_3/UV法对炼油含碱废水降解的试验研究

Experiment of Using UV/O_3 as a Pretreatment Technology to Degrade the Refinery Basic Sewage

炼油含碱废水中COD、Oil、Ar-OH、S2-浓度较高,可生化性极差,选用O3/UV的方法对其进行降解研究,结果表明,通过控制O3浓度、反应时间,可使各污染物的降解达到预处理的目的。与单独用O3法相比,UV使COD、Oil、Ar-OH的平均降解率分别提高了24%、31%、28%。同时此反应具有不产污泥、没有二次污染等优点。

s:UV/O3 technology was used to degrade the refinery basic sewage with high concentration of COD, oil, Ar OH, S2 .The resultshowed that the degradation rates of COD,oil,Ar OH,S2 are increased 24% ,31% and 28% respectively by using the UV/O3 incomparison with O3 method alone.The degradation rates of pollutants could meet the requirements by controlling the O3 concentration and reaction time.
