Abstract In order to evaluate the treatment efficiency of fresh landfill leachate by anaerobic digestion, and to explore the measures to improve the efficiency and process stability, the present study assessed the effect of low, medium and high food to microorganism ratio (F/M) (i.e., 0.49, 1.02 and 1.92g-leachate COD/g-sludge VS). Meanwhile, wood chars of <5μm, 75~150μm and 2~5mm, and bamboo biochar of 75~150μm were added at high F/M, and compared for their effects on the anaerobic digestion of leachate. The results showed that the leachate methanation was seriously delayed and the operation was unstable at high F/M. Compared with the control group without biochar addition at high F/M, the maximum methane production rate was increased by 179%, 93%, 83% and 64%, the total effluent dissolved nitrogen was decreased by 21%, 16%, 16% and 12%, and the NH₄⁺-N of the total effluent was decreased by 17%, 16%, 16% and 12%, respectively, for the scenarios of adding wood char of <5μm, 75~150μm, 2~5mm and bamboo biochar of 75~150μm. The degradation of organic matters and organic acids, especially the degradation of n-butyric acid and acetic acid in the <5μm wood biochar group, was significantly faster than that of other biochar groups. These results show that biochar can improve the efficiency and process stability of leachate anaerobic degradation. For wood biochar, the smaller the particle size was, the better performance was.
