Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a microorganism-based sewage treatment agent. In other words,
11 (Relates to a microorganism-based aromatic and fast-acting sewage treatment agent used in both toilets, which has high cleanliness, and in particular contains organic substances that produce aromatic components through the action of microorganisms.

[Prior Art] Conventional tit dual-use toilet treatment agents mainly contain no microorganisms, and their main components are disinfectants, pigments, and fragrances.

In this case, most of the disinfectants are sodium hypochlorite, the pigments are those for food additives such as Blue No. 1 and Blue No. 2, and the fragrances are those with a residual odor. They used strong oil fragrances absorbed by talc or zeolite.

Conventionally, microbial-based sewage treatment agents have not been used much, but among the Bacillus genus, especially Zuptilis (B.
5ubtilis), it decomposes organic filth, and some have a bacterial count of 10' to 109/g.

Others include lactic acid bacteria and soil microorganisms. In addition to the above-mentioned microorganisms, some microorganisms can coexist with enzymes such as amylase, proteinase, and lipase.

Conventional microorganism-based sewage treatment agents are thought to be mainly based on Bacillus subtilis (B. 5ubtilis). Such sewage treatment agents have a small number of bacteria to avoid decomposing organic waste, and other types of bacteria that coexist do not promote the decomposition of waste.Normally, this type of bacteria produces bad odors by itself. This makes it unsuitable for treating foul-smelling filth from vehicle toilets. In addition, there was a mixture of microorganisms such as Bacillus and enzymes such as amylase, proteanase, and lipase, but due to the high cost of enzymes, it was not practical. The use of sewage treatment agents was considered technically and economically unsuitable.

[Problems to be Solved by the Invention] Therefore, as a result of intensive research into microorganism-based sewage treatment agents that had never been seen before, the present invention found a way to solve the problem by combining microorganisms, and based on that knowledge. The present invention has been made based on this. Therefore, the present invention can decompose organic sewage that gives off a bad odor in toilet sewage in a short time, almost eliminate odor, and maintain the color and cleanliness.In particular, the present invention can clean the toilet of a running vehicle, The purpose of the present invention is to provide a microorganism-based sewage treatment agent for toilets that not only makes filth odorless but also contains an organic substance that produces aromatic components. That is, the present invention produces a substance that can be added to the toilet of a moving vehicle to make the toilet clean and odorless, and also makes wastewater discharged from a sewage treatment plant odorless and colorless, and has an aroma. The purpose of the present invention is to provide a novel sewage treatment agent that can reduce the amount of odors and reduce bad odors.

[Means for Solving Problems] The convenience of the present invention is to add 0 parts by weight of a pigment component to 100 parts by weight of a microorganism component consisting of a microorganism, a culture medium, and a carrier.
．． This microorganism-based sewage treatment agent is characterized in that it contains 5 to 2.0 parts by weight, 10 to 40 parts by weight of a soft drink, and 10 to 40 parts by weight of a lactic acid fermentation product. The microbial component is composed of four or more types of microorganisms,
The number of bacteria per gram of the microbial component is Bacillus (Bacillus).

Preferably, the amount of bacteria of the genus is 109 to 10''7g.

The present inventors first added 0.5 to 0.5 parts of a pigment component to 100 parts by weight of a microbial component consisting of a microorganism, a medium, and a carrier.
We proposed a microorganism-based sewage treatment agent for toilets containing 2.0 parts by weight and 10 to 60 parts by weight of fragrance ingredients. The microbial component is composed of three or more types of microorganisms, and the number of bacteria per gram of the microbial component is Bacillus (
10" to 10" 7 g of bacteria belonging to the genus Bacillus, and 109 to 109 g/g of bacteria belonging to the genus Streptococcus.

We proposed that the bacteria of the genus Enterobacter were 107+109/g.

In contrast, the present invention proposes a sewage treatment agent that is more quickly effective and contains an organic substance that produces aromatic components. In addition, the action of microorganisms has been further improved to make it useful as a sewage treatment agent for Shinkansen trains that treat filth on a daily basis.

According to the present invention, for example, 1 g of a microbial component per 100 parts by weight of a microbial component consisting of a microorganism, a culture medium, and a carrier.

The microbial component of the microorganism-based sewage treatment agent for toilets of the present invention is composed of microorganisms, a culture medium, and a carrier, and the culture medium serves as food for the microorganisms used. Agricultural by-products such as soybean residue, wheat bran, and bagasse whose composition is clear to some extent are used, or spoiled beverages such as milk are used. It is possible to use drugs together.

In addition, the carrier used in the present invention is a carrier for the microorganisms used, and in the case of an inorganic powder (including a porous material), it is preferably a carrier of returned acid carunium, magnesium carbonate,
Using calcium silicate powder, in the case of organic powder,
Sawdust etc. can be used.

This means that the pigment component is based on 100 parts by weight of the microbial component.
If it is less than 0.5 parts by weight, the hue will not be sufficient and cleanliness cannot be maintained, and if it exceeds 2.0 parts by weight,
The color is so dark that it cannot be erased at sewage treatment plants, causing pollution as the wastewater becomes visible.

In the microorganism-based sewage treatment agent of the present invention, by converting inexpensive soft drinks and lactic acid fermentation products into flavor components with aroma through the action of microorganisms, the blending amount of the component flavor components (ttt) is greatly reduced. This can significantly improve costs.

In other words, if the soft drink has a weight of less than 101%, the amount of aroma (fragrance) components produced is small, and the aroma cannot be imparted sufficiently.
If the amount exceeds 40 parts by weight and 1 part by weight, the amount of aromatic components produced will be too large, giving an unpleasant feeling. If the lactic acid fermentation product is less than 10 parts by weight, the amount of aroma components produced is small and the aroma cannot be exhibited, and if it exceeds 40 parts by weight, the amount of aroma components produced is too large, causing discomfort. give.

Contains bacteria of the genus Cellulomonas ((:elluloa+onas) at a ratio of 109-10"7g. In other words, bacteria of the genus Bacillus decomposes organic waste such as starch and protein in 24 hours at less than 1011. If the capacity is insufficient and exceeds 101/g, 1. There will be a limit to growth in coexistence with other species of bacteria, and it will also cause a bad odor.

Also, Streptococcus
If the bacteria of the genus s) is less than 10", it is insufficient to decompose sugars such as glucose in 24 hours, and if it exceeds 1611/g, no further decomposition processing capacity is required, and it is difficult to combine with pond species. This will limit the growth of coexistence.Also, Enterobacter
If the bacteria of the genus Enterobacter are less than 10", the decomposition of sugars in 24 hours is insufficient;
If the amount exceeds 0.17 g, the number of bacteria that produce yellow pigment within 24 hours will increase, which will limit the ability to grow in coexistence with other species of bacteria.

For the following reasons, the microorganism-based sewage treatment agent for toilets of the present invention has the above-mentioned compounding ratio.

The Rhizopus genus bacteria that are added secrete a very powerful saccharifying enzyme, which rapidly converts the rehydrated substances in toilet waste into sugars, greatly enhancing the effect of Bacillus. The sugars and hydrocarbons obtained in this way are transferred to Streptococcus
ococcus genus and Enterobacter
Rhizopus (
When bacteria of the genus Rhizopus are mixed in, the decomposition of filth and the source of bad odors can be completed in an extremely short time. If the Rhizopus genus bacteria is less than 109/g, its ability to decompose sugars is insufficient, and if it exceeds 101'/g, there will be a limit to its growth in coexistence with other species of bacteria.

In addition to decomposing toilet filth, the four types of bacteria shown in A-H decompose carbohydrates and fruit juice components in soft drinks and lactic acid fermentation products, which are especially added in the present invention, and aromatic flavor components ( (chemical structure is not clear) can be produced.

If the Nitrosomonas genus bacteria is less than 106/g, it is insufficient to convert annium to NO3, and if it exceeds 109/g, it is difficult to coexist with other species of bacteria. It becomes the limit of proliferation.

As described above, the sewage treatment agent of the present invention contains these eight types of bacteria and aims to achieve a comprehensively balanced decomposition of toilet waste. By fulfilling their respective functions, the above eight types of bacteria can decompose toilet waste and transform it into substances that are almost the same as the main constituents of activated sludge in sewage treatment plants. The sewage treatment function can be maintained without reducing the function of the system.

In addition, the odor in toilets and treatment plants can be reduced by masking the scent components that are produced at the same time.
