<p>PROBLEM TO BE SOLVED: To efficiently deodorize by performing pretreatment of washing by water and using a resin-made biological carrier. SOLUTION: This biological deodorizing device is composed of a washing column 1a, a deodorizing column integrated with a deodorizing chamber 1b in which the resin made biological carrier is packed, auxiliary machines, auxiliary facilities and an automatic control device. Ammonia is previously removed by performing the pretreatment with washing to decrease the generating quantity of nitrous acid and high deodorizing efficiency is attained by using the resin made carrier having excellent water holding property and small air permeating resistance.</p> |
