Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a circulating toilet filth treatment agent.

That is, the present invention relates to an improved circulating toilet filth treatment agent that accelerates the dissolution of blue pigment and also enables early confirmation of whether or not the circulating toilet filth treatment agent has been added.

[Prior art and problems to be solved by the invention] Circulating toilet filth treatment agents include (1) those mainly containing sodium hypochlorite, (2) glutaraldehyde as a deodorant, and (1) There are others, but among these, (1) has a pungent odor peculiar to sodium hypochlorite, and if the amount of urine collected increases, the odor cannot be suppressed, and it also bleaches and decomposes the blue pigment. It cannot be colored for the purpose of imparting a clean feeling. On the other hand, (like conventional products), most of the products that use glyoxal or glutaraldehyde as main ingredients are liquid products, and require a lot of effort in terms of containers and work time.

In addition, when added to collected urine, it suppresses the odor to some extent in the first half, but it remains stable over time and maintains its deodorizing effect.
Even if dyes were added to U-4 to give it a clean feel, it was difficult to maintain its formulation and hue.

For example, when these conventional products are used in circulating toilets on trains, the circulating toilet waste treatment agent is added to the water that is injected into many waste tanks in a short period of time. There are some gaps, and the presence or absence of blue color is a major criterion when checking.

However, with conventional products, it takes about 2 to 1 hours after being put into the waste tank.
Since the blue color does not develop or develop until 4 hours have elapsed, mistakes were sometimes made in checking whether or not the processing agent had been added to these operations, which was a major problem.

The present invention is a circulating system that greatly speeds up the dissolution or development of the blue pigment, which was a problem in the conventional technology, in the glutaralde-L treatment agent, and makes it easier to check when it is added. The purpose is to provide a toilet filth treatment agent.

[Means for solving the problems] The gist of the present invention is that 1 to 10 parts by weight of a blue pigment,
14 to 50 parts by weight of organic acid, 7 to 25 parts by weight of sodium bicarbonate
A total of 100 parts by weight of pigment composition components consisting of 91120 to 80 parts by weight of potassium sulfate, 20 to 70 parts by weight of glutaraldehyde, and 40 to 160 parts by weight of rice starch.
parts by weight, 20 parts by weight or less of Guri'kisal, and 20 parts by weight of fragrance
This is a circulating l/ile filth treatment agent characterized by being composed of a two-component system with a total of 150 parts by weight of deodorant composition components consisting of 150 parts by weight or less.

The applicant has filed Japanese Patent Application No. 63-141520υ, 63-16.
No. 0961, 63-236361υ, 63-30394
No. 8 has been filed, but in order to cover up the bad odor of the bacteria itself and the bad odor until the decomposition of waste is finished, it is necessary to use perfumes with a high residual odor and Zeolite 4 powder. It absorbs the source of bad odors, and the amount of such fragrance ingredients added is also large, which is a problem from a perspective of smell. In addition, the invention filed in No. 3] 1 requires a soft drink or a lactic acid fermentation product, so handling is a problem. In addition, in the invention filed last, 41 aircraft filth is decomposed by bacteria, and the source of bad odors such as 4-4-1, which is not completely decomposed by the microorganisms, such as hydrogen sulfide, is treated with chemicals, and the bacteria itself The odor can be eliminated using chemicals, and the amount of fragrance ingredients can be reduced or eliminated.

According to the present invention, as described above, the pigment composition component 100
150 parts by weight and 150 parts by weight of the deodorant composition component.The pigment composition component is encapsulated in water-soluble paper, and when it is completely put into the waste tank, it comes into contact with water. At the same time, a foaming phenomenon occurs due to the chemical reaction between the organic acid and sodium hydrogen carbonate, and the blue pigment can be rapidly dispersed and dissolved in the water phase due to the foaming force diffusion.

Additionally, when the deodorant composition components are encapsulated in water-soluble paper and placed in a filth tank, they gradually dissolve and can fix or mask the foul odor of filth.

The components according to the invention are: 1 to 10 parts by weight of blue pigment, 14 to 50 parts by weight of organic acid, 7 to 25 parts by weight of sodium bicarbonate A
a total of 100 parts by weight of pigment composition components consisting 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, 20 parts by weight or less of glyxal, and It is composed of a two-component system with a total of 150 parts by weight of deodorant composition components consisting of 20 parts by weight or less of fragrance.

The components contained in the pigment composition components are as follows.

The blue pigment colors toilet filth blue and gives it a talin look. In addition, this pigment needs to disappear by activated sludge treatment during wastewater treatment. As the pigment, acidic pigments (Blue No. 1, Blue No. 2, etc.), basic pigments (methylene blue, etc.), natural dyes (Gardenia, Spirulina, etc.), etc. can be used. Blue pigments are often used in powder or solid form, and efforts are being made to dissolve them. The proportion of the blue dye is in the range of 1 to 10 parts by weight, and if it is less than 1 part by weight, the color tone will be weak and a clean feeling will not be exhibited. In addition, if it exceeds 10 parts by weight, the color tone will be too strong and the talin effect will not be exhibited, and furthermore, the purification ability will be reduced. The result is not favorable.

The organic acid reacts with the sodium hydrogen carbonate contained in the pigment composition components to foam carbon dioxide gas, and the blue pigment is rapidly dissolved by this foaming force diffusion. Furthermore, this organic acid suppresses and controls sources of bad odor such as ammonia in toilet filth, and at the same time prevents the pH of toilet filth from shifting to the alkaline side and causing corrosion of the toilet bowl base material.

Specifically, linchoic acid, citric acid, tartaric acid, oxalic acid, etc. are suitable. The content of the organic acid is in the range of 14 to 50 parts by weight. If it is less than 14 parts by weight, it is insufficient to prevent equipment such as toilet bowls from being corroded by the torque. If it exceeds 50 parts by weight, then p)
l: The balance of + control is disrupted, and the foaming power is too strong, resulting in explosive foaming. Furthermore, the toilet waste becomes acidic and corrodes the toilet fixtures, which is undesirable.

Sodium bicarbonate reacts with organic acids to foam envy-acid gas, and this foaming and diffusion has the effect of rapidly dissolving the blue pigment.
It keeps H at approximately neutrality and prevents corrosion of equipment such as toilet bowls and tanks. And its content ratio is 7 to 25
Parts by weight range.

If it is less than 7 parts by weight, p) (a adjustment is insufficient, and
The foaming power is also insufficient for hue development.

Moreover, if it exceeds 25 parts by weight, the foaming power will be too strong, resulting in explosive foaming, which is undesirable, and at the same time, the pH will shift to the alkaline side, causing corrosion of toilet waste containers, tanks, and other equipment. .

Potassium sulfate is a neutral, easily water-soluble, and non-reactive crystal. Therefore, a poorly water-soluble blue dye is applied to the surface of this potassium sulfate crystal by mixed dyeing, dispersion, and dissolution in the aqueous phase. Used to assist in hue development. It is also essential for preventing chemicals from absorbing moisture and preventing M absorption.

The content of potassium sulfate is 20 to 80 parts by weight.

If it is less than 20 parts by weight, it is insufficient to develop the hue, and if it exceeds 80 parts by weight, the amount is too large and is disadvantageous in terms of C1 cost.

20 to 70 parts by weight of glutaraldehyde, 40 to 160 parts by weight of rice starch, 20 parts by weight or less of glyoxal,
The components of the deodorant composition with a total amount of 150 parts by weight, which is composed of 20 parts by weight or less of perfume, are as follows.

Glutaraldehyde fixes and deodorizes the bad odor generated by toilet waste. However, it cannot be used in the form of a solid or powder, and is usually used in the form of a 25-50% aqueous solution, so in order to form a powder, one carrier that adsorbs water is required.

The content of gluculaldehyde is in the range of 20 to 70 parts by weight. If the amount is less than 20 parts by weight, it will not be possible to sufficiently adsorb sources of bad odors contained in or generated in filth. If it exceeds 70 parts by weight, the pungent odor of glutaraldehyde itself becomes strong and the clean feeling deteriorates.

Rice starch is used as a carrier that adsorbs or occludes glutaraldehyde itself, as well as the water and flavor liquid contained in glutaraldehyde, and removes and releases it over time. The particle size, specific surface area, and surface morphology of Rice Scooch match these purposes, and in particular, it absorbs or occludes gluculaldehyde, which is the main ingredient in deodorants, and gradually releases it over time to eliminate it. It is effective in eliminating odor and maintaining the deodorizing effect over a long period of time.

The content of rice starch is in the range of 40 to 160 parts by weight. If the amount is less than 40 parts by weight, the glutaraldehyde itself or the water contained therein will be adsorbed and it will not cut. On the other hand, if the amount exceeds 160 parts by weight, the amount of the processing agent increases, which is disadvantageous for :JS1.

Glyoxal fixes the bad odor generated by toilet filth, and also has the role of stabilizing and promoting the effect of glutaraldehyde, the main deodorant. If it exceeds 20 parts by weight, the deodorizing effect will not increase significantly even if added.

Fragrances are necessary to some extent because they give a sense of cleanliness to people using the toilet. −・Generally, in general,
Abietic acid derivatives, lauryl methacrylate, chlorophyll, etc. are used. In this case, if the fragrance exceeds 10 parts by weight, the fragrance will be too strong and cause discomfort.
It is necessary in an amount proportion of 10 parts by weight or less.

By such a combination, the circulating toilet filth treatment agent of the present invention having the above-mentioned structure can also be obtained.

Historically, the circulating toilet filth treatment agent of the present invention can also be used for treating wastewater from factories that emit bad odors in areas other than toilets.

Next, the circulating toilet filth treatment agent of the present invention will be explained using specific examples, but the present invention is not limited to the following examples.

[Example] [Production of treatment agent] According to the formulation shown in Table 1, the pigment composition component and the deodorant composition component were each thoroughly ground and mixed in an agate bowl for 10 minutes to obtain a powder treatment agent. .

1 In addition, in the formulation table of Table 1, 100 parts by weight of the pigment composition component and 150 parts by weight of the deodorant composition component are used.

[Cleanliness test] Example 1 of the circulating toilet filth treatment agent obtained in Section 112.
Regarding 2.3, the following test was conducted.

Assuming a train toilet, 0.7 parts by weight of the circulating toilet filth treatment agent of the present invention was added to 100 parts by weight of the initial water, and the color development was measured by the time it took to obtain the hue. Next, assuming that the train toilet will be used for 4 days, 50 parts by weight of sewage made by mixing human urine and feces at a weight ratio of 19:1 was compared with commercially available products A, B, and C. A total of 200 parts were added once for 7 days, during which time 3
Continue shaking at 5°C, and check the hue and odor for each 1]]
Observe.

2 As can be seen from Table 1 and Table 2, the product of the present invention exhibited a sufficient blue color 3 to 10 minutes after the treatment agent was added, and was evaluated as ■.

It also had an excellent odor and clean feel. On the other hand, in a comparative example using a conventional commercially available product, from the time of adding the processing agent,
It was not until after 123-21'2 minutes that it had settled to the bottom of the container to develop a sufficient blue color.

Furthermore, it did not exhibit sufficient deodorizing properties.

[Effects of the Invention] The microorganism-based circulating toilet filth treatment agent of the present invention exhibits the following deodorizing effects, making it extremely effective as a toilet filth treatment agent.

That is, first, by blending an appropriate amount of an organic acid and sodium hydrogen carbonate and utilizing the foaming power of carbon dioxide gas, 1,-
If the amount of these ingredients is increased, it will turn blue in a very short time from the time it comes into contact with the charging water, for example, within 3 to 10 minutes in the example, so it will be extremely easy to check the charging process during and immediately after the charging process. Become. This is extremely important as it has to be done during extremely short intervals during train cleaning work. On the other hand, commercially available products require 123 to 212 minutes, which is 10 times longer than the processing agent of the present invention.

Second, in order to enhance the action and effect described in the first point, a poorly water-soluble blue dye is sufficiently mixed with easily water-soluble potassium sulfate, a blowing agent, an organic acid, and sodium hydrogen suboxide, and a partially There is also a coating and sufficient mixing is achieved.

Thirdly, the desired deodorizing effect is also fully achieved by using glutaraldehyde and glyoxal together.

Fourth, since it is a powder product, it is easy to handle.

As described in -1- above, the toilet filth treatment agent of the present invention can quickly determine whether or not it has been added, and can exhibit a deodorizing effect and a clean feeling with a blue hue over a long period of time. Industry-1- as it does not interfere with the wastewater treatment process.
It is extremely meaningful.
