The experiment was intended for improving property of oxygen-releasing material through adding bentonite,KH2PO4 and (NH4)2SO4 into calcium peroxide (CaO2).The results of the continuous column experiment show that the oxygen-releasing material could decrease O2-releasing rate and lengthen O2-releasing duration. The DO can retain more than 5 mg/L for long time. In addition, KH2PO4, (NH4)2SO4 and the natural aquifer can better buffer pH and meet the need of bioremediation. %K O2-releasing material %K pH %K permeable reactive barrier %K groundwater %K in situ bioremediation
