摘要

来自突尼斯Sfax排放区的垃圾渗滤液(LFL)具有化学需氧量(COD)、铵盐含量高的特点。它们对地下水和地表水资源构成植物毒性和污染源，需要适当的处理过程。为了评价混凝/絮凝处理的效果，特别关注了pH、混凝剂和絮凝剂剂量的影响。然后，研究了零价铁单独使用和混凝/絮凝预处理的效果。结果表明，混凝/絮凝法(COD为46%，浊度为63%)和Fenton法(COD为48%，浊度为76%)的去除率较高。混凝/絮凝与Fenton联合应用，COD去除率达到62%，浊度降低90%。结果表明，该联合处理方法对有机化合物的降解和处理后的渗滤液毒性的降低具有一定的适用性。

Evaluation of influence of coagulation/flocculation and Fenton oxidation with iron on landfill leachate treatment

Landfill leachates (LFL) collected from Sfax (Tunisia) discharge area are characterized by high chemical oxygen demand (COD), ammonium and salts contents. They constitute a source of phytotoxicity and pollution for ground water and surface water resources which requires an adequate treatment process. To evaluate the efficiency of the coagulation/flocculation treatment, special attention was paid to the effect of pH, coagulant and flocculant doses. Then, effect of zero valent iron was also studied alone and in combination with coagulation/flocculation pretreatment. Our results indicate high removal efficiencies by coagulation/flocculation (46% COD and 63% turbidity) and Fenton process (48% COD and 76% turbidity). The combined application of coagulation/flocculation and Fenton revealed higher COD removal (62%) and turbidity reduction (90%). These results showed the applicability of this combined treatment method for the degradation of organic compounds and reduction of the treated leachate toxicity.
