In order to alleviate pollution of urban sewage river sediment, planting experiment is conducted to study phytoremediation of Lolium Perenne to heavy metal pollution in the circumstance of adding hydrogen peroxide before planting. Results show that after adding hydrogen peroxide before planting Lolium Perenne in sediment the total concentration of lead and cadmium in sediment decline and the ion exchangeable phase of heavy metal increases a lot. The amount of ion exchangeable phase of lead in sediment after adding hydrogen peroxide before planting Lolium Perenne is 46.27 mg/kg which is larger than the one of only planting by 16.58 mg/kg. While the amount of lead of ion-exchangeable phase in original sediment is only 0.001mg/kg. The amounts of carbonate bound, Fe-Mn oxide bound and organic bound also show adding hydrogen peroxide before planting Lolium Perenne can promote accumulation and translocation of heavy metals to plants. Therefore adding hydrogen peroxide in phytoremediation experiment will become an efficient method to solve the problem of contamination of heavy metal in sewage river sediment.
