UV/Fenton联合生物接触氧化工艺去除废水中LAS应用研究

Application Research of LAS in Wastewater Removal of UV/Fenton Combined with Biological Contact Oxidation Process

针对直链烷基苯磺酸钠(LAS)的降解机理,选择UV/Fenton法联合接触生物氧化法处理LAS高盐废水,结果显示:UV/Fenton工艺降解效果明显优于Fenton工艺,对于含LAS污染物存在一个H2O2和Fe SO4最佳投加量,采取H2O2分批投加的方式确实能够提高处理效果。

In view of linear alkylbenzene sulfonate （LAS）degradation mechanism,the UV/Fenton method combined with biological contact oxidation process were selected to treat LAS wastewater with high salinity.The results showed that the UV/Fenton process degradation effect was obviously better than that of the Fenton process. LAS pollutants had the best dosage of H2O2 and FeSO4.The UV/Fenton process with H2O2 batch addition way could improve treatment effects.
