Description

Description: TECHNICAL FIELD The present invention relates to a recycle toilet waste treatment agent. That is,
The present invention relates to a circulating toilet sewage treatment agent that has been improved so as to accelerate the dissolution of a blue pigment and to promptly confirm the presence or absence of the addition of the circulating toilet sewage treatment agent.

[Problems to be Solved by the Prior Art and the Invention] As the recirculating toilet waste treatment agent, (1) a product mainly containing sodium hypochlorite, (2) glutaraldehyde is used as a deodorant, and (3) ) There are others, but of these,
(1) has an irritating odor peculiar to sodium hypochlorite, and when the amount of human waste increases, the odor cannot be suppressed.
Since it has the effect of bleaching and decomposing blue dye, it cannot be colored for the purpose of imparting a clean feeling. On the other hand, in the case of (2), as in the case of the conventional products, when glyoxal or glutaraldehyde is used as a main agent, there are many liquid products, and much time is required for devising containers and working time. In the first half of the addition to human waste, the odor is suppressed to some extent, but it is difficult to maintain the deodorizing effect stably with time and it is difficult to add a dye to impart a clean feeling. However, it has been considered difficult to maintain the composition and hue.

When these conventional products are used, for example, in a circulating toilet for a train, the circulating toilet sewage treatment agent is added to the immersion water previously injected into a large number of sewage tanks in a short time. At the time of checking, the presence or absence of blue color is a major criterion.

However, conventional products are put into a waste tank,
Until 14 hours have passed, the blue color does not develop or develop color, so there were occasional mistakes in checking whether or not a processing agent had been added to these operations, which was a major problem.

The present invention relates to a glutaraldehyde-based treating agent,
It is an object of the present invention to provide a circulating toilet waste treatment agent in which dissolution or development of a blue pigment, which has been a problem in the prior art, is greatly accelerated, and a check at the time of introduction is surely and easily performed.

[Means for Solving the Problems] The gist of the present invention is to provide 1 to 10 parts by weight of a blue pigment,
Organic acid 14-50 parts by weight, sodium hydrogen carbonate 7-25 parts by weight, potassium sulfate 20-80 parts by weight total 100
Parts by weight of the dye composition component and glutaraldehyde 20 to 70
It is characterized by a two-component system consisting of a total of 150 parts by weight of a deodorant composition component consisting of 40 parts by weight of rice starch, 40 to 160 parts by weight of rice starch, 20 parts by weight or less of glyoxal, and 20 parts by weight or less of fragrance. It is a recycled toilet waste product.

The present applicant has filed Japanese Patent Application No. 63-141520 (JP-A-1-310,799).
No. 7), 63-160961 (JP-A-2-14798),
63-236361 (JP-A-2-86,896), 63-303948
(Japanese Patent Application Laid-Open No. 2-152,594), the former two methods use a fragrance with a high residual odor to cover the bad odor of the bacteria itself and the bad odor until the decomposition of the filth is completed. Since the odor source is adsorbed on the zeolite powder, the amount of such a fragrance component is large, which is a problem in terms of cost. In addition, the third invention of the present application requires a soft drink and a lactic acid fermentation product, so handling is a problem. In the invention finally filed, organic filth is decomposed by microorganisms, and malodorous sources such as ammonia and hydrogen sulfide generated without being completely decomposed by microorganisms are treated with chemicals. , Control its upbringing,
The amount of the fragrance component may or may not be small.

According to the present invention, as described above, the dye composition component 100
Parts, and a two-component system consisting of 150 parts by weight of a deodorant composition component, and the pigment composition component is contained in water-soluble paper, and when put into a waste tank, water and Simultaneously with the contact, a foaming phenomenon occurs due to a chemical reaction between the organic acid and sodium bicarbonate, and the blue pigment can be rapidly dispersed and dissolved in the aqueous phase due to the foaming force diffusion.

On the other hand, when the deodorant composition component is contained in a water-soluble paper and put into a waste tank, it gradually dissolves and can fix or mask the bad smell of toilet waste.

The component according to the present invention comprises 1 to 10 parts by weight of a blue pigment, 14 to 50 parts by weight of an organic acid, 7 to 25 parts by weight of sodium hydrogen carbonate,
A total of 100 parts by weight of a dye composition component composed of 20 to 80 parts by weight of potassium sulfate, 20 to 70 parts by weight of glutaraldehyde, 40 to 160 parts by weight of rice starch, and 20 glyoxal
Total of less than 20 parts by weight and less than 20 parts by weight of fragrance
It is composed of a two-component system with 150 parts by weight of a deodorant composition component.

And as a component contained in the dye composition component,
It looks like this:

The blue pigment is used to color toilet sewage blue to give a clean feeling. In addition, this pigment needs to be eliminated by activated sludge treatment during wastewater treatment. As the dye, an acidic dye (eg, Blue No. 1, Blue No. 2), a basic dye (eg, methylene blue), a natural dye (eg, gardenia or spirulina) can be used. The blue pigment is
It is often used as a powder or solid, and it is devised to dissolve it. The ratio of the blue pigment is 1 to 10
If the amount is less than 1 part by weight, the color tone is weak,
Clean feeling is not exhibited. Also, if the amount exceeds 10 parts by weight, the color tone is intense and a clean feeling cannot be exhibited.
When the purification ability is reduced and the wastewater is treated, blue color is not decomposed and remains as a color tone, which is not a favorable result.

The organic acid reacts with sodium hydrogen carbonate contained in the dye composition component to foam carbon dioxide gas, and rapidly dissolves the blue dye by this foaming force diffusion. In addition, the organic acid suppresses malodor sources such as ammonia in the toilet waste, and at the same time, prevents the pH of the toilet waste from shifting to the alcal side to prevent corrosion of the toilet base material.

Specifically, malic acid, citric acid, tartaric acid, oxalic acid and the like are preferred. The content ratio of the organic acid is in the range of 14 to 50 parts by weight. If the amount is less than 14 parts by weight, the action of the pH control to prevent corrosion of equipment such as a toilet bowl is insufficient. If the amount exceeds 50 parts by weight, the balance of the pH control is lost, and the foaming power is too strong, resulting in explosive foaming.
Furthermore, toilet waste becomes acidic, corroding toilet equipment,
Not preferred.

Sodium bicarbonate reacts with an organic acid to foam carbon dioxide gas, which has the effect of rapidly dissolving the blue pigment by the foaming diffusion.At the same time, it keeps the pH of toilet sewage almost neutral, and the toilet bowl and tank It prevents corrosion of equipment such as. And the content ratio is in the range of 7 to 25 parts by weight. If the amount is less than 7 parts by weight, the pH adjustment is insufficient,
In addition, the foaming power is insufficient for hue development.

Also, if it exceeds 25 parts by weight, the foaming power is too strong and explosive foaming is not preferable because it is unfavorable, and at the same time, the pH shifts to the alkaline side, causing corrosion of equipment such as toilet waste containers and tanks. .

Since potassium sulfate is a neutral, easily water-soluble, and non-reactive crystal, a poorly water-soluble blue dye is mixed and dyed on the surface of the potassium sulfate crystal, and dispersed and dissolved in an aqueous phase, that is, a hue. Used to assist in the deployment of Further, it is indispensable for preventing the chemical from absorbing moisture.

The content ratio of potassium sulfate is 20 to 80 parts by weight. 20
If the amount is less than part by weight, the development of the hue is insufficient. If the amount is more than 80 parts by weight, the amount is too large, which is disadvantageous in cost.

Glutaraldehyde 20-70 parts by weight, rice starch 40
~ 160 parts by weight, glyoxal 20 parts by weight or less, and flavor 2
A total of 150 parts by weight of the deodorant composition component composed of 0 parts by weight or less is as follows.

Glutaraldehyde fixes malodor generated by toilet waste and deodorizes it. However, it cannot be used as a solid or a powder, and is usually used in the form of a 25 to 50% aqueous solution. Therefore, in order to form a powder, a carrier that adsorbs this moisture is required.

The glutaraldehyde content is in the range of 20 to 70 parts by weight. If the amount is less than 20 parts by weight, it is not possible to sufficiently adsorb the odor source generated in the toilet waste or generated. If it exceeds 70 parts by weight, the irritating odor of glutaraldehyde itself becomes strong, and the clean feeling is reduced.

Rice starch is used as a carrier that adsorbs or occludes glutaraldehyde itself or the liquid components of moisture and fragrance contained in glutaraldehyde and removes and releases them over time. Rice starch meets these objectives in terms of particle size, specific surface area and surface morphology.In particular, it absorbs or absorbs glutaraldehyde, which is the center of the deodorant, and gradually releases it over time to deodorize. It is effective to maintain the deodorizing effect for a long period of time.

The content ratio of rice starch is in the range of 40 to 160 parts by weight. If the amount is less than 40 parts by weight, glutaraldehyde itself or contained moisture is adsorbed and cannot be cut. Also,
If the amount exceeds 160 parts by weight, the amount as a processing agent increases, which is disadvantageous in cost.

Glyoxal fixes malodor generated by toilet waste, but has a role of stabilizing or promoting the effect of glutaraldehyde, which is a main deodorant. If it exceeds 20 parts by weight, the deodorizing effect does not increase so much even if it is added.

Fragrance is necessary to some extent to give a person using the toilet a clean feeling. Generally, in general,
An abietic acid derivative, lauryl methacrylate, chlorophyll, or the like is used. In the case of this formulation, if the fragrance exceeds 10 parts by weight, the fragrance is too strong and gives uncomfortable feeling.
It is necessary in an amount ratio of not more than parts by weight.

With such a composition, the recycle toilet waste treatment agent of the present invention having the above-described configuration can be obtained.

Furthermore, the recycle toilet waste treatment agent of the present invention can also be used for the treatment of industrial wastewater that emits an odor other than toilets.

Next, the circulating toilet waste treatment agent of the present invention will be described with reference to specific examples, but the present invention is not limited to the following examples.

[Example] [Manufacture of treating agent] According to the composition shown in Table 1, each of the pigment composition component and the deodorant composition component was pulverized and mixed well in an agate for 10 minutes to obtain a powder treating agent. .

In the composition table of Table 1, 100 parts by weight of the dye composition component and 150 parts by weight of the deodorant composition component are used.

[Cleaning test] The recycling toilet waste treatment agent obtained above Example 1,
The following tests were performed on a few samples.

Assuming a train toilet, 0.7 parts by weight of the circulating toilet waste treatment agent of the present invention was added to 100 parts by weight of the first immersion water, and the color development at that time was indicated by the time until the hue was obtained. Compared with commercial products A, B, and C, then, assuming that train toilets will be used for four days, human urine and stool were mixed at a weight ratio of 19: 1, and 50 parts by weight of sewage was added. Add 200 parts by weight per day, during which time shaking is continued at 35 ° C., and the hue and odor are observed every day.

As can be seen from Table 2, the product of the present invention exhibited a sufficient blue color 3 to 10 minutes after the treatment agent was charged, and was excellent in odor and clean feeling. On the other hand, in the comparative example using the conventional commercial product, the color was not blue enough and was deposited at the bottom of the container until 123 to 212 minutes after the treatment agent was introduced. Also, it did not show sufficient deodorizing properties.

[Effects of the Invention] The microbial recycle toilet waste treatment agent of the present invention is remarkably effective as a toilet waste treatment product by having the following deodorizing effect.

That is, first, an appropriate amount of an organic acid and sodium hydrogen carbonate are blended, and by using the foaming power of carbon dioxide gas, if these blending amounts are increased, an extremely short time from the point of contact with the immersion water, For example, in the embodiment, in 3 to 10 minutes,
Because of the blue color, it is extremely easy to check the input during and immediately after the input operation. This is extremely important because it must be done in a very short time between train cleaning operations. On the other hand, a commercially available product requires 123 to 212 minutes, which is 10 times or more the time required by the treatment agent of the present invention.

Secondly, in order to enhance the action and effect described in the first aspect, a poorly water-soluble blue pigment is sufficiently mixed with a water-soluble potassium sulfate, an organic acid as a foaming agent and sodium hydrogen carbonate, and partially , Coatings have been achieved and adequate mixing has been achieved.

Third, the objective deodorizing effect is sufficiently achieved by using glutaraldehyde and glyoxal together.

Fourth, handling is easy because it is a powder product.

As described above, the toilet waste treatment agent of the present invention can quickly determine the presence or absence of its introduction, can exhibit a deodorizing effect and impart a clean feeling by a blue hue for a long time, and interfere with the wastewater treatment process. No, it is very significant in industry.
