| 摘 要： | 研究了Fenton试剂对底泥-水体系中低浓度DDE的降解作用，探讨了pH、[Fe2^2 ]0、[H2O2]0以及水和泥的质量比(水／泥)等影响因素。结果表明，pH，[Fe^2 ]0以及[H2O2]0的最佳条件值分别为3．0，16mmol／L和400mmol／L，DDE降解率随水／泥比的增大而提高，反应60分钟时DDE的降解率达70％。

| Abstract: | The degradation of low concentration DDE with the slurry as medium by fenton reagent was studied and the experiments on the influence factors such as pH, [Fe2+ ]0 , [H2O2]0 and mass ratio of water and mud were carried out. The results show that the optimal pH, [Fe2+ ]0 and [H2O2]0 is 3.0, 16mmol/L and 400mmol/L respectively. The degradation efficiency of DDE was improved with the increasing of the mass ratio of water and mud. The 70% of DDE could be degraded after 60 minutes reaction. |
