HIGH-EFFICIENCY BIOLOGICAL DEODORIZING DEVICE USING CERAMIC CARRIER FOR IMMOBILIZING MICROORGANISM

摘要

PURPOSE:To provide the high-efficiency biological deodorizing device using ceramic carriers for immobilizing microorganisms which can sufficiently assure the water necessary for buffering the reaction products for growing microorganisms in a filter bed and maintaining high bioactivity and can grow the microorganisms at a high density. CONSTITUTION:The filter bed section 2 consisting of the plural carriers 3 for immobilizing the microorganisms is provided in the mid-way of the flow passage for a raw gas 6 in a reaction column 1. The carriers 3 are formed of the ceramics materials having plural through-holes 10 to such a size as to attain 40 to 50% in-carrier voids which are the property value at the time of packing and =13mmAq/m pressure drop in the filter bed section at the time of packing. The carriers 3 are so formed that the in-carrier voids A attain 40 to 50% and the pressure drop B=13mmAq/m, by which the growth of the microorganisms with the sufficient water retention, gas contact surface area and high density is obtd. and therefore, the sufficient deodorizing effect is exhibited.
