The technology used the coagulation-sedimentation + electro-oxidation joint reactor has been studied to treat landfill leachate. First adding FeCl30.4g/L into all leachate for coagulation and sedimentation, its CODcr elimination rate can achieve 35%, but does have no effect on ammonia nitrogen. Then using electro-oxidation reactor to deal with effluent water, the reaction order of electro-oxidation reactor is first-level, as the reaction conditions are 20mA/cm2 of electric current density, 140min of reaction time, the leachate CODcr elimination rate can reach to above 90%, the ammonia nitrogen elimination rate meets to 98% around. Using coagulation-sedimentation + electro coagulation joint reactor to treat landfill leachate can get stable effluent water quality with good treatment effect, has very high elimination efficiency of CODcr and ammonia nitrogen. It is a suitable treatment technology for landfill leachate.

Sanitary Landfill Leachate

Sanitary landfill leachate (LL) composition varies according to climate variables variation, solid waste characteristics and composition, and landfill age. Leachate treatment is essentially carried out trough biological and physicochemical processes, which have showed variability in efficiency and appear a costly solution for the management authorities. Electrocoagulation (EC) seems a suitable solution for leachate treatment taking into account the characteristics of the liquor. One of the problems of EC is the electrode passivation, which affects the longevity of the process. One solution to this problem could be the replacement of the electrode by one made of recyclable material, which would make it possible to change it frequently and at a lower cost. The objective of the present work was to evaluate the removal of heavy metals (As, Ba, Cd, Cr, Cu, Fe, Pb, Mn, Ni, Se and Zn) and coliforms from a LL by EC using electrodes made from steel swarf (SfE) up to 8 h. Removal efficiencies of detected heavy metals were 51%(Cr), 59%(As), 71%(Cd), 72%(Zn), 92%(Ba), 95%(Ni) and >99%(Pb). The microbial load of coliforms in leachate was reduced from 10.76 × 104 CFU/mL (raw leachate) to less than 1 CFU/mL (after treatment with SfE) (i.e., approximately 100% reduction). The use of SfE in EC of LL is very effective in removing heavy metals and coliforms and can be used as alternative treatment solution for such effluents.
