Problems solved by technology

[0006] However, there is a problem that it is difficult to completely eliminate the odor of excrement such as feces and urine, and the method of using the above-mentioned deodorant cannot sufficiently deodorize the unpleasant odor.
[0007] In addition, in the above-mentioned deodorizing method, it is necessary to have a replenishment tank for storing circulating water mixed with a deodorant, or a circulating facility for circulating water, and there is a problem that a large-scale device is required.

Embodiment 1

[0101] (Preparation of Odor Converting Components)

[0102] The raw materials of the odor conversion components shown in Table 1 were put into a mixing tank, mixed and stirred, and an odor conversion component was prepared. Specifically, a solvent was put into a mixing tank equipped with a heating device according to the compounding method shown in Table 1, and then other raw materials were sequentially added, and stirred at 20° C. for 30 minutes to prepare an odor conversion component.

[0103] (Preparation of oil agent for odor conversion)

[0104] As an oil component, sorbitan monooleate (HLB is 4.3) was prepared, and the odor conversion component prepared above and sorbitan monooleate were prepared in a mass ratio of 1:1. Method Mix at room temperature in a mixing tank to prepare an oil agent for odor conversion.

[0105] (preparation of lubricating oil)

[0106] 50 cc of the oil agent for odor transformation prepared above and 4950 cc of lubricating oil were filled in ...

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.

Description

technical field [0001] The invention relates to a method for transforming odor. Background technique [0002] At present, the bad smell when excrement is extracted from the toilet by a sanitation vehicle (vacuum vehicle) has become a problem. Generally, when excrement is sucked by a sanitary vehicle, the inside of the excrement tank is depressurized by a vacuum pump, and the excrement is sucked into the excrement tank through a hose connected to the excrement tank. In addition, when excrement is discharged, the inside of the excrement tank is pressurized by a vacuum pump, and the excrement is discharged out of the excrement tank through a hose connected to the excrement tank. [0003] When the above excrement is sucked or discharged, the foul-smelling air in the excrement and urine tank is exhausted to the outside, which causes an unpleasant feeling to the operator and nearby residents, which becomes a problem. [0004] Especially when excrement is sucked, it is necessary ...
