Abstract: PURPOSE: A lateral surface filtering type biofilter is provided in which polluted air is introduced into in a direction of lateral surface of the biofilter to maximize an inflow cross-sectional area of the polluted air, and a purification method of polluted air using an electric biofilter is provided. CONSTITUTION: The lateral surface filtering type biofilter comprises a cylindrical housing part(3) equipped with upper and lower surfaces at the center of which a vent(1) is positioned, wherein an inlet(2) is formed on the lateral surface of the housing part; and a filter part(7) formed in a doughnut type cylinder shape which is positioned inside the housing part, in which a filter filling material is filled in a space between a concentric circle shaped net type outer wall(4) and a net type inner wall(5), and a cavity of the center of which is connected to the vent(1) of the housing part, wherein the lateral surface filtering type biofilter further comprises an injection pipe(6) which is positioned at the upper part of the housing part(3) to supply moisture and nutritive elements to the filter filling material, and a flow meter(8) which is attached to the vent of the housing part to measure the amount of air treated, the filter filling material comprises activated carbon capable of adsorbing polluted air outstandingly, compost used as a culture medium of microorganisms, sawdust and microorganism source, and the microorganism source is a supernatant of a culture fluid which is prepared by cultivating activated sludge obtained from a sewage disposal plant or a supernatant of castings of an earthworm. The method for purifying polluted air using the lateral surface filtering type biofilter comprises the steps of flowing the polluted air into the inlet(2) of the lateral surface filtering type biofilter, and exhausting the purified air through the vent.
