<P>PROBLEM TO BE SOLVED: To provide an absorption tower and a biological deodorization apparatus in which the shape of a sponge material can be kept for a long period of time, and the advantage thereof as a porous material is used, and the absorption efficiency of an odorous substance or the like can be maintained for a long period time. <P>SOLUTION: The absorption tower includes: a gas-liquid contact layer; a liquid supply device supplying a liquid to the gas-liquid contact layer; and a gas-supplying part supplying a gas to the gas-liquid contact layer, wherein a prescribed component included in the gas is absorbed into the liquid at the gas-liquid contact layer. The gas-liquid contact layer includes: two or more porous materials of a plate or sheet shape being parallel by a standing position; and two or more insertion members disposed to be brought into contact with the porous material alternately, and sandwiching the porous material. The insertion members have an unevenness surface profile, and form a gap in which the gas can pass by the unevenness at a space with the porous material. The biological deodorization apparatus includes the absorption tower, the gas-liquid contact layer retains a microorganism that can decompose an odorous substance, the liquid is water, and the odorous substance included in the gas is absorbed by the water and is decomposed by using the microorganism. <P>COPYRIGHT: (C)2013,JPO&INPIT |
