Title: ODOR MODULATION METHOD
Abstract:
The present invention provides an odor modulation method that makes it possible to modulate, into a different odor, the unpleasant, bad odor that is generated when excrement is sucked from a toilet by a sanitation vehicle or discharged from the sanitation vehicle, thereby making it possible to easily reduce the harm done by the bad odor. An odor modulation method that is characterized by having: a step in which a vacuum pump reduces the pressure of a feces/urine tank of a sanitation vehicle and excrement is sucked through a hose that is connected to the feces/urine tank; and/or a step in which the vacuum pump increases the pressure of the feces/urine tank and excrement is discharged through the hose that is connected to the feces/urine tank. The odor modulation method is also characterized in that lubricating oil used in the vacuum pump contains an odor-modulating oil.
