本研究采用辐射技术对某城市生活垃圾焚烧厂经膜分离处理后的新鲜渗滤液出水进行深度处理。采用伽马辐照-混凝法对MBR处理出水的COD去除率进行了研究。实验结果表明，4 kGy γ辐照对COD的去除率可达45.3%。混凝与辐照相结合可提高COD去除率。当投加铁盐进行混凝处理时，COD去除率可达55.2%，投加量为1 kGy。为了进一步提高渗滤液中COD的去除率，在未来的研究中还需要进行更多的研究，例如将辐射工艺与生物处理工艺相结合，以提高COD的去除率。
In this study, the radiation technology was used for the advanced treatment of effluent of fresh leachate from a municipal solid waste incineration plant which was treated by membrane separation processes. The COD removal percentage of the effluent from the MBR treatment process was investigated by gamma irradiation combined with coagulation process. The experimental results showed that the removal percentage of COD could achieve 45.3% by gamma irradiation alone at the dose of 4 kGy. The COD removal percentage could be improved by the combination of coagulation with gamma irradiation. Particularly, the removal percentage of COD could increase to 55.2% at the dose of 1 kGy, when iron salt was used for the coagulation process. More researches are required in future study for further increasing the removal percentage of COD of leachate, for example, integrating radiation process into biological treatment process to enhance the COD removal.
