摘要
利用臭氧和Fenton试剂对某石化炼油厂电脱盐废水进行了处理。结果表明:经臭氧处理后COD去除率为51.10%;用Fenton试剂处理经臭氧氧化后的电脱盐废水,效果最好,COD去除率提高到84.61%;用臭氧和Fenton试剂联合处理时,COD去除率为77.95%;这3种方法都能减轻该种废水的后续处理压力,其中第2种方法效果最好。
Treatment of electric desalting wastewater by ozone and Fenton reagent was studied in this paper. The experiment results showed that the removal rate of COD was 51. 10% after the ozone treatment,Fenton reagent was employed for the treatment of the effluent,and the COD removal rate could reach to84. 61%. The combination treatment of ozone and Fenton reagent presented perfect efficiency for discoloration and odor removal,and 77. 95% of COD was removed after the treatment. With the help of these three methods,the pressure of following treatment section would be reduced.
