Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewage treatment agent which can be conveniently used for aircraft circulation type toilets and has a deodorizing effect. In particular, it relates to a plant essential oil-based sewage treatment agent for aircraft circulation type toilets, which is mainly composed of plant essential oil.

2. Description of the Related Art Conventionally, as an aircraft circulating type toilet waste treatment agent, one that is chemically decomposed by using acid or alkali, or one that is decomposed by being immersed in a solution containing an enzyme or a microorganism is used. ing. Of these, those that use formaldehyde or chemicals such as sodium hypochlorite as toilet treatment agents do not give a good impression due to the peculiar odor of the chemicals themselves, and the effective time is short. Alternatively, it cannot be colored blue. Further, the chlorine-based treatment agent has many problems such as generation of chlorine gas when decomposing wastes, and formaldehyde may be one of the factors causing secondary pollution. In addition, there were some concerns about the stability and immediate effect of the deodorizing effect.

Further, the above-mentioned conventional waste treatment agents cannot avoid performance deterioration due to temperature and pH changes. In particular,
There are times when an aircraft flies below zero, and sometimes at an airfield in the tropics.
Toilet odor became dominant and could not be deodorized by conventional methods. In addition, deodorization may be hindered by the effect of adding a strong alkaline substance or the like that is thrown into the toilet. In addition, it is considered necessary to take into consideration the pH change due to foodstuffs that passengers carelessly add.

Further, in the conventional treating agents, it is difficult to remove and deodorize for a relatively long period of time, and chemical agents are mainly used. For example, formaldehyde and sodium hypochlorite are often used. . In addition to this, there is also a combination of a microorganism and a plant extract oil, which is a type in which a microorganism decomposes filth and the generated ammonium or hydrogen sulfide is absorbed and treated in the plant extract oil. . A deodorant utilizing microorganisms decomposes filth, suppresses a bad odor such as ammonia, and adsorbs it. However, if the conditions are not satisfied, it may have an adverse effect. In the case of a combination of microorganisms and plant extracted oil, the microorganisms decompose organic matter in the waste, and the plant extracted oil cannot sufficiently process the malodor generated by ammonia, hydrogen sulfide, methyl mercaptan, etc. for 3 to 4 days. Prolapse of
Deodorization is also difficult. Further, in the above method, since the dye is decomposed, it is not possible to mix the dye having a clean feeling, and the clean feeling is lacking. Furthermore, the deodorizing effect must be maintained between long-distance flights of the aircraft, which is difficult with the conventional methods.

[0005] Furthermore, some of the usual plant essential oils have a neutralizing effect on the malodor, but they have a max effect, but the actual effect is small and insufficient.

[0006]

DISCLOSURE OF THE INVENTION In order to overcome the above problems, the present invention has been earnestly studied in order to sufficiently consider the obstruction of the deodorizing effect due to the temperature change in a wide range, and as a result, as a countermeasure against these problems. , Using the plant essential oil obtained by ethyl acetate extraction and water extraction of the leaves of a coniferous tree having a strong antibacterial activity,
By increasing the preservative power with diol compounds,
Deodorant made into powder by making it have a stable deodorizing effect even in a wide temperature change, by further adding a fragrance to enhance the malodor removal, and by using anhydrous magnesium sulfate together. That the pH range is reduced by adding an organic acid to suppress the generation of ammonia, and the blue dye gives the customer a clean feeling, and the wastewater treatment By decontaminating activated sludge in the field, it was easy to decolorize and did not affect microorganisms. By taking the above-mentioned five means, it was possible to provide a more effective soil treatment agent than the conventional treatment agents.
