ABSTRACT:
A circulatory microorganic deodorizing system has the inner space of a tower main body partitioned into an upper deodorization chamber, a middle level deodorization chamber, and a lower deodorization chamber. In the lower deodorization chamber, exhaust gas G is brought into contact with process water in a filmy state and cooled down while water soluble offensive odor constituents and dust, contained in the exhaust gas G, are removed by absorption. Water soluble offensive odor constituents and dust, contained in polluted water, are cleansed through decomposition and deodorization processing by the agency of microorganisms, and residual offensive odor constituents are adsorbed and then decomposed by the agency of a filler and microorganisms in the middle level deodorization chamber and the upper deodorization chamber, respectively, so that the exhaust gas G is completely deodorized. Thus, the problem of deodorizing agents being clogged, resulting in deterioration of deodorizing capacity as with the case of conventional deodorizing systems is solved.
