<p>PURPOSE:To obtain a compact deodorizing apparatus by forming an inorg. basic material layer in which microorganisms having deodorizing action are allowed to live and a peat layer in which microorganisms having deodorizing action are allowed to live in a vessel. CONSTITUTION:Malodorous gas is introduced into the lower part of a vessel 6 after the flow rate is regulated with a flowmeter 5. In the vessel 6, H2S is chiefly removed from the gas by passing through a ceramics packed bed (inorg. basic material layer) 7 in which microorganisms having deodorizing action are allowed to live. The ceramics is made of blast furnace slag. Basic substances such as NH3 are then removed from the gas by passing through a peat packed bed 8 in which microorganisms having deodorizing action are allowed to live and the deodorized gas is released into the air from a nozzle 9. To make microorganisms layers, in case of the inorg. layer, fluid contg. microorganisms is circulated to the top of the bed 7 by a pump 12 and sprinkled and in case of the peat layer, peat is preliminary controlled its PH and mixed microorganisms.</p> |
