<p>PURPOSE:To remove a malodor generating cause by sterilizing bacteria or the like, by contacting ozone gas with a deodorizing object. CONSTITUTION:The ozone gas-containing air A passing through an ozonizer 4 is introduced into waste water 7 through an air stone 8 to aerate the waste water 7. Whereupon, the ozone gas-containing air A and the waste water 7 are uniformly mixed and contacted and the bacteria causing a malodor proliferating in the waste water 7 are sterilized to remove the generation of the malodor. By this method, pleasant atmospheric environment can be obtained.</p> |
