  • A micro-electrolysis procedure for decomposing organic pollutions in stabilized landfill leachate pretreatment was optimized,and performances of the procedure were investigated. The results showed that the optimal pH was 4.0,the volume fraction of cast iron scraps to that of granular active carbon was 1:2,and the reaction time was 1.5 h. Under the optimal procedure,the removal rates of chemical oxygen demand (COD) and refractory organic chemicals of stabilized landfill leachate were 84.5% and 89.9%,respectively. After the pretreatment by micro-electrolysis method,the biodegradablity coefficient of the leachate increases by 116.6%,and the concentration of refractory organic chemicals in the leachate decreases by 32.8%.
