A gas (atmosphere) containing a malodor is mixed with the atmosphere of the place and is generated. If the atmosphere is released into the atmosphere,
It causes pollution problems such as foul odors. Therefore, how to remove the bad odor contained in the gas is currently an issue. For example, when the removal of malodor is highly required,
A means of using a high-performance filter that highly adsorbs and captures a component causing a bad odor is adopted. In addition, when the bad odor is not required to be removed so highly, a gas containing a bad odor is introduced into water and bubbled, and the gas discharged from this is discharged to the atmosphere through an adsorbent layer such as sawdust. . As an example of the former, it is adopted as a measure against foul odors at food waste processing plants, and as a latter, it is adopted as a measure against foul odors in poultry houses and cattle stalls, egg washing facilities, milking facilities, etc.

.About.2,7, effective chlorine concentration is 25 to 60 mg / L, and redox potential is 1100 mV or more (for example, 1150 mV). In the present invention, this electrolytically generated acidic water is used as a malodor removing agent. Further, the obtained electrolytically-generated alkaline water has a pH of about 11.5 to 12.0 and has a high cleaning action, and for the purpose of sanitary control and the like, a place where an offensive odor source exists, for example, a food factory, a waste treatment plant, It is used in large quantities for cleaning floors, equipment, devices, etc. of poultry houses, pig houses, cow houses, etc.

These malodorous components are produced directly in the facility and are mixed in the facility atmosphere, and the bacteria existing in the atmosphere decompose and alter various components contained in the atmosphere. This is due to the fact. Therefore, in order to remove the malodor contained in the atmosphere, the malodorous components may be decomposed and converted into odorless components, and the bacteria may be killed. The electrolyzed acidic water, particularly the strongly acidic electrolyzed acidic water has an excellent bactericidal action against various bacteria and an action of decomposing various malodorous components.

た。得られた結果を図４のグラフに示す。In this experiment, a plurality of containers each having a capacity of 3 L were used as T
Put MA in each container and T
An MA atmosphere was created. In each of these containers, 10 mL of each of the removing agents A to d was dropped, and the TMA concentration of the atmosphere in each container after 1 minute was measured with a gas detection tube,
The relationship between each remover A to D and the TMA concentration in the atmosphere was obtained. The obtained results are shown in the graph of FIG.
