PACKING MATERIAL FOR BIOLOGICALLY DEODORIZING MALODOROUS GAS, METHOD AND APPARATUS FOR BIOLOGICALLY DEODORIZING MALODOROUS GAS

摘要

PPROBLEM TO BE SOLVED: To provide a packing material for deodorization whose deodorizing performance is improved and which reduces the cost of equipment and to provide a deodorizing method and a deodorization apparatus in which the packing material is used. PSOLUTION: This packing material consists of a plurality of plate-like porous bodies each of which has a three-dimensional network structure and communicated pores inside and in each of which the number of pores lined on one straight line per 25 mm is different from that of pores lined on another straight line, a plurality of modules obtained by packing an inorganic particulate packing material having different particle sizes separately into molding flasks of optional shapes, a plate-like ceramic porous body having a three-dimensional network structure and communicated pores inside, a module obtained by alternately arranging the plate-like ceramic porous body and a plate-like foamed plastic body or a plate-like fibrous packing material or a formed body obtained by sticking granular or crushed particles of a porous inorganic substance to one another at contact points and forming the stuck particles into a plate-like or columnar aggregate. The malodorous gas is deodorized biologically by packing this packing material into a packed layer, sticking a microbe to the packed layer and bringing the malodorous gas into contact with the packed layer.
