摘要:Landfill leachate is a complex mixture containing toxic and recalcitrant substanceswith considerably low BOD5/COD indicating the necessity and difficulty of itstreatment. Amongst treatment processes, integrated separating-destructiveprocesses are promising gones. In this way, suspended and colloidal particles getseparated in a separating process, while the soluble fraction under goes separatingprocess; probably an coagulation-flocculation process. In this study, coagulationprocess using ferric chloride was employed as apre-treatment process for landfillleachate. Elimination of COD and turbidity was investigated using responsesurface method (RSM) with Box-Behnken design. Design experiments weremodeled and analysed. In optimum conditions (7.2g/L FeCl3 and 0.2mL/Lflocculant) the average COD removals were occurred approximately 45%.
