Title:
生物脱臭装置の馴養方法
Document Type and Number:
Japanese Patent JP4026256
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To raise the ammonia load syncronizingly with an acclimatizing stage and to smoothly advance the proliferation of nitrifying bacterium by introducing gaseous ammonia in a suitable amount in accordance with the acclimatizing stage during the acclimatizing term of a carrier packed biologically deodorizing device for deodorizing ammonia. SOLUTION: The waste gas sent from a waste gas supply pipe 2 to a biologically deodorizing column 1 is discharged from a discharge pipe 6 while passing through a packed layer 3 and while transferring the ammonia to treating water to decompose. In such a case, in the case where the acclimatization in which the amount of the nitrifying bacterium is gradually increased just after depositing sewage sludge, etc., on the packed layer 3 is executed, the raw gas for acclimatization regulated to a prescribed concn. by diluting the waste gas or commercially available gaseous ammonia with the air is introduced. Then the treating water 41 is sprinkled to the packed layer 3 from a sprinkling line 4 to dissolve the ammonia in the treating water 41. Thereafter, the ammonia concn. in the raw gas for the acclimatization is regulated to maintain the amount of the nitrifying bacterium in constant while measuring the pH value of the drain stored in a water storage tank 5 with a pH meter.
