%X The nitric oxide (NO) emission could be removed effectively by rotating drum biofilter. In order to enhance the performance of rotating drum biofilter, the effect of medium configuration on the NO removal efficiency was investigated. The results showed that compared with the single-layer rotating-drum biofilter, the multi-layer rotating-drum biofilter was operated more stablely and achieved higher removal efficiencies. The experimental data demonstrated that the NO removal efficiency of the multi-layer rotating-drum biofilter was maintained between 53.9% and 93.4%. Compared with 68.7% average NO removal efficiency of the single-layer rotating-drum biofilter, the NO removal efficiency of the multi-layer rotating-drum biofilter could reached 79.8%. Under the same experimental conditions, the empty bed residence time of the multi-layer rotating-drum biofilter dropped from 86.4 s to 57.6 s of the single-layer rotating-drum biofilter. The optimum conditions for the multi-layer rotating-drum biofilter were the amount of nutrient solution between 1.3 L to 3 L and the rotating speed 0.75 r·min-1. The experimental data also illustrated that the removal efficiency maintained stable when TOC exceeded 1250 mg·L-1 using glucose as the carbon source.
