2. Description of the Related Art Lactic acid bacteria are good for the human body
Proven from old times and in recent medical aspects, it has been utilized and utilized in various dietary habits as an intestinal bacterium and a beneficial bacteria essential for health. Bacteria that ferment sugars to produce a large amount of lactic acid are collectively referred to as lactic acid bacteria, which are generally Gram-positive bacteria, and the bacterial form is mainly bacilli or cocci. In addition, it does not form endospores and shows negative catalase. Motility is rarely shown. It is an essential condition for lactic acid bacteria to grow that the lactic acid bacterium grows rich in nutrients such as sugar components serving as energy sources, amino acids for constructing bacterial cell components, and vitamins and minerals as growth factors. Most lactic acid bacteria are facultatively anaerobic and grow while gaining energy by fermentation, so they can grow with or without oxygen. In addition, since oxygen toxicity can be eliminated, it will not be killed even if it comes into contact with oxygen like an absolutely anaerobic bacterium. The temperature condition for growing the lactic acid bacterium is 4 ° C. or higher and 50 ° C. or lower, and it inhabits, for example, food, the digestive tract system of an animal (in the oral cavity, lumen, intestinal tract, etc.), the inside of the vagina, animal feces or soil.

In the septic tank 20, residual substances 3 and 4 such as nitrogen compounds and hydrogen sulfide adhere, and miscellaneous bacteria 5 which are putrefactive bacteria propagate. The bacteria 5 decomposes (rotates) the residual substances 3 and 4 by aerobic oxidation to generate a bad odor containing a harmful substance (rotted odor). In addition, the germs 5 themselves generate a foul odor. Among the residual substances 3 and 4, particularly the nitrogen compound 3 such as ammonia produces an ammonia odor. Further, the nitrogen 3a contained in the nitrogen compound 3 serves as a basis for generating the water-bloom 6.

The LBF aqueous solution 2 put in the septic tank 20
Lactobacillus fermentum 1 contained therein is a facultative anaerobic bacterium, and it is a septic tank 2 in a state where oxygen is not consumed.
Fermentation of the sugars 7 remaining in the mixture 0 removes the various bacteria 5 that cause an acidic substance such as lactic acid 8 produced at that time to cause a bad odor. In addition, acidic substances such as lactic acid 8 are
It never creates an anaerobic condition, which is a condition for growth. Therefore, the germs 5 such as putrefactive bacteria in the septic tank 20 are removed, toxic gases such as ammonia and methane and compounds such as lower fatty acids, amines and hydrogen sulfide are not produced, and the water quality is purified and the malodor is removed.

Lactobacillus fermentum removes an ammonia odor by decomposing a nitrogen compound 3 such as ammonia, which is a basis for propagation of various bacteria 5. This is because anaerobic lactic acid bacteria such as Lactobacillus fermentum 1 decompose nitrogen 3a in ammonia as an amino acid in order to maintain the nitrogen balance. In general, lactic acid bacteria become ammonium lactate 9 when combined with nitrogen compound 3 (ammonia water).
The total nitrogen content is reduced by the fermentation of the yeast 10 that co-exists. By decomposing the nitrogen compound 3 and reducing the amount of nitrogen in this way, the generation of ammonia odor is significantly suppressed, and therefore it is also effective in suppressing odor. In addition, the reduction of the total nitrogen amount prevents the generation and propagation of the water-bloom 6 in the septic tank 20.

As a result, the septic tank 20 installed at a high cost can be effectively reused even after the sewer is shared,
We will suppress the generation of industrial waste due to demolition and removal, and reduce demolition costs. In addition, the septic tank 20 is used as a rainwater storage tank to protect water resources and compensate for water shortage. Especially in regions and seasons with low rainfall, the effect of water saving and drought reduction is great and it contributes to the reduction of water charges. The stored water can be used not only for washing cars, sprinkling trees, flower beds, etc., but also can be expected to play a role of a fire prevention tank, and can be used as stored water for initial fire extinguishing when a fire occurs. Moreover, in the future, due to the spread of public sewers, the number of unnecessary septic tanks 20 will increase.
