(First embodiment)
As shown in FIG. 1, the circulation type toilet according to the first embodiment of the present invention is a circulation type toilet that treats excrement based on the combined fermentation method and circulates and reuses the treated water as washing water. .

The term “complex fermentation” used in the present specification refers to an organic / replacement / replacement based on the substrate and metabolism, causing the combined action of simple fermentation to re-fermentation, parallel re-fermentation, equilibrium re-fermentation, and solid fermentation. A chain circulation fermentation method that creates a biological information energy catalyst and creates its state. Such a chain-circulating fermentation leads all microorganisms to an effective ecosystem, generates an interlocking cycle of information and energy on the microorganisms, expresses the circulatory action of the microorganisms, and realizes coexistence, mutual prosperity, and symbiosis.

More specifically, as shown in FIG. 2, first, the aerobic fermentation microorganisms start working. Here, the fermentation microorganisms are yeast, lactic acid bacteria, etc., and physiologically active substances such as amino acids, vitamins, minerals, etc. Make and suppress aerobic bacteria such as E. coli and filamentous fungi. Next, lactic acid bacteria relay to facultative anaerobes, actinomycetes appear to make antibacterial substances, and anaerobic bacteria such as pathogenic bacteria and viruses are purified. When these two bactericidal actions are linked, nitrogen-fixing bacteria such as Azotobacter and rhizobia take in gas from the air and fix it. Finally, gas with photosynthetic bacteria, algae, and chemically synthesized bacteria immobilized. Is converted into useful substances and energy, such as photosynthesis. By continuing this cycle, the organic sludge is converted (decomposed) into gas and water.

In this invention, in order to implement | achieve these combined fermentation in the limited space called a toilet, the fermenter 2 which arrange | positioned the manure excreted with water, paper, etc. from the toilet bowl 1 as shown in FIG. ”,“ Fermentation synthesis tank 3 ”,“ fermentation sedimentation tank 4 ”, and“ synthesis tank 5 ”are characterized in that they are continuously fermented at different anaerobic degrees while maintaining a predetermined number of cells.

That is, in the present invention, a toilet that saves space within a range in which excrement (processing object) from the toilet and excrement (processing amount) of several to several tens of times per day are assumed in advance, For example, excrement in a portable toilet can be treated with a complex fermentation method in a space-saving manner. For this reason, in the circulating toilet of this embodiment, “fermentation synthesis tank 3”, “fermentation precipitation tank 4”, and “synthesis tank 5” are arranged immediately above “fermentation tank 2” as the first fermentation tank. Thus, the processed material and microorganisms are continuously circulated between these tanks.

In addition, in this invention, as it mentions later, anaerobic degree is high as it transfers to "fermenter 2", "fermentation synthesis tank 3", "fermentation precipitation tank 4", "synthesis tank 5", and the downstream fermenter. Fermentation (complex fermentation in which anaerobic bacteria predominate over aerobic bacteria) occurs. Furthermore, the bacteria bed part from the fermentation sedimentation tank 4 is shifted to the fermentation tank 2, by circulating, to ensure the number of cells microorganism for performing fermentation treatment more than a predetermined number (e.g., 10 ⁹ / cc or higher) Can do.

Therefore, as shown in FIG. 1, a fermenter 2 that is a first processing tank is disposed immediately below the toilet 1. Note that the term “arranged immediately below the toilet 1” used in the present invention means that it is disposed directly below a support member of the toilet such as a floor.

Further, a shape that is wide in the horizontal direction and shallow in the vertical direction generally means a range up to a full space that can be taken directly under an installation place such as a floor.

In this embodiment, the fermenter 2 disposed immediately below the toilet 1 is widely disposed horizontally below the floor, which is the installation surface of the toilet 1.

The fermenter 2 is a fermenter configured to be wide in the horizontal direction and short in the vertical direction, and a plurality of aeration means 21 are provided at the bottom of the fermenter 2.

When the urine is flowed from the toilet 1 together with water and paper to the fermenter 2 configured in this way, mainly aerobic fermentation occurs under aerated conditions.

The fermentation that occurs in the fermenter 2 of the present invention is mainly aerobic fermentation (for example, fermentation at a ratio of aerobic fermentation 9: anaerobic fermentation 1). The term “mainly aerobic fermentation” used in the present specification means aerobic / anaerobic combined fermentation in which aerobic fermentation is dominant, and means that some anaerobic fermentation occurs. In other words, the fermentation that occurs in the fermenter 2 of the present invention means an aerobic / anaerobic combined fermentation in which aerobic fermentation is dominant (fermentation in the combined fermentation shown in FIG. 2 (start)).

Moreover, as shown in FIG. 1, in this embodiment, the fermentation synthesis tank 3 for carrying out the primary process in the fermenter 2 (combined fermentation was started) and processing the processed material immediately above the fermenter 2; A fermentation sedimentation tank 4 and a synthesis tank 5 are arranged.

Fermentation synthesis tank 3 is a second fermentation tank having aeration means 31 that is long in the vertical direction and narrow in width. In this fermentation synthesis tank 3, fermentation with anaerobic degree higher than that of fermentation tank 2 occurs. More specifically, in the fermentation synthesizer 3, combined fermentation occurs at a ratio of “both aerobic fermentation and anaerobic fermentation”, for example, aerobic bacteria 5: anaerobic bacteria 5.

In the embodiment shown in FIG. 1, one fermentation synthesis tank 3 is arranged. However, the number of fermentation synthesis tanks 3 is not limited to one, and may be, for example, 2 to 3 (described later). 5).

Next, the fluid processed in the fermentation synthesis tank 3 is sent to a fermentation precipitation tank 4 arranged in parallel with the fermentation synthesis tank 3.

The fermentation sedimentation tank 4 has a function of dividing the fluid sent from the fermentation synthesis tank 3 into a fungus bed part and moisture, and returning the fungus bed part to the fermentation tank 2 while sending moisture to the subsequent synthesis tank. . In the fermentation sedimentation tank 4, fermentation (fermentation in which anaerobic fermentation is superior) occurs at a higher anaerobic degree than the fermentation synthesis tank 3, and solid fermentation occurs at the bottom of the fermentation precipitation tank 4. As used herein, the term “solid fermentation” refers to fermentation performed by microorganisms adhering directly to or penetrating solids without using water directly (Applied Microbiology, Sawao Murao, Motoo Arai). (See joint edition).

The fungal bed portion returned from the fermentation settling tank 4 to the fermenter 2 has not yet been prepared by preparing a suitable fermentation environment in the fermenter 2 (increasing effective bacterial cells and suppressing oxidized bacteria) and circulating and performing fermentation. Circulate the processed product. By circulating treatment in this way, the microorganisms in the fermenter 2 have a higher concentration and the amount of enzyme increases (higher concentration of microorganism and higher concentration of enzyme in FIG. 2).

Further, the synthesis tank 5 is arranged in parallel with the fermentation precipitation tank 4 and has a function of processing the water sent from the fermentation precipitation tank 4 to optimize the water.

The synthesis tank 5 is a tank for performing biocatalyst and enzyme catalyst treatment with photosynthetic microorganisms, algae, algae and the like. Crystals of physiologically active substances are obtained by the catalytic action of these photosynthetic bacteria and algae, and normal temperature superconductivity, which is an action between substances, is terminated. The function of bacteria is terminated in the synthesis tank 5 and the DNA of the bacteria is decomposed to convert the bases into original proteins and use them as crystals.

The synthesis tank 5 further has an ion catalyst layer made of an organic energy medium and an inorganic medium (C · SiO 2, Ti, Fe, Al, Cu, Mg, Li, Be, B etc.). These ion catalyst tanks cause atom, ion level transition, displacement, and sublimation (disappearance). Moreover, the energy transfer by an organic protein crystal | crystallization is also performed simultaneously, and the water | moisture content sent from the fermentation precipitation tank 4 is optimized as water for washing.

The water thus treated is sent to the washing tank 6 through a microfilter as desired.

In the circulation type toilet according to the first embodiment, the fermentation synthesis tank 3, the fermentation precipitation tank 4, and the synthesis tank are arranged immediately above the fermentation tank 2, and are moved downstream while continuously circulating in a limited space. Thus, the fermentation is carried out with a high anaerobic degree, and the cells produced in the fermentation sedimentation tank 4 where the fermentation with a high anaerobic degree is carried out are returned to the fermenter 2. For this reason, it has become possible to perform complex fermentation in a limited space in which fermentations with different anaerobic degrees are continuously performed while maintaining a predetermined number of cells or more.

In this way, since complex fermentation can be carried out effectively, it becomes possible to treat urine washed with paper together with water without odor. Moreover, the recycled water can be reused by returning the treated water to the washing tank 6 as washing water.

Therefore, once water is poured into the washing tank 6, emergency toilets, disaster toilets,
A space-saving toilet that can be used effectively in various situations such as a toilet for an event can be realized.
