Different Chemical Oxidant of Benzene Series Pollution Site Repair Effect

this study intends to compare through the experiment research of potassium permanganate, Fenton reagent, sodium persulfate, hydrogen peroxide, four kinds of commonly used oxidant chlorobenzene in contaminated soil, the removal effect of O-O-dichlorobenzene;, selected a typical ground soil bioremediation is the best antioxidant effect. Research under the condition of different on the dose, 4 kinds of oxidants to chlorobenzene and O-O-dichlorobenzene; removal effect. Combined pollution ground soil properties screen of chlorobenzene in contaminated soil, the highest removal rate of dichlorobenzene oxidant and best delivery dosage, to apply typical ground soil bioremediation, the results show that the effect is the best Kmno4.
