Field of the Invention The present invention relates to a circulation purification device that circulates and uses treated water, and more specifically, a toilet for a moving body such as a train or a bus, and a temporary installation used at a construction site, an event venue, or the like. The present invention relates to a circulation purification device for treating human waste water, such as a toilet, which circulates the treated water and uses it as toilet flush water.

は、尿石の付着による弊害が顕著に現れることがある。[0002] In the background art toilet, adhesion of urine stone to the toilet and waste water flows through the pipe results in a blockage of the pipe. In addition, it is considered that microorganisms propagate using urine stones as a hotbed, and the decomposed products often cause a bad odor. In particular, in a circulation-type purification device that treats waste water and circulates and reuses the water to be treated, adverse effects due to the adherence of urinary stones may be remarkable.

題がある。It is considered that urea in urine stone urine urine is converted into ammonia by microorganisms, whereby the pH in human urine rises and calcium ions in human urine precipitate as calcium phosphate, calcium carbonate and the like. In other words, it is considered that the production thereof is related to the pH environment and existing microorganisms. Therefore, in order to prevent the precipitation of urinary stones, it is possible to add a sterilizing agent that produces chlorine, for example. However, there are problems such as lack of convenience such as continuous feeding and control of the amount.

When the treated water that has been subjected to electrolysis is reused as cleaning water, precipitation of urine stones in the toilet bowl and other circulation routes is effectively suppressed.

It is considered that the reason for this is that hypochlorous acid is generated as a result of electrolysis and sterilization is performed by it. Chloride ions are generally present in human waste (the amount thereof is reported to be about 0.6%, for example). Depending on a general treatment method, chlorine ions in human waste are not removed but remain in treated water. It is considered that when such treated water is electrolyzed, hypochlorous acid is generated, and sterilization is performed by this. The production of urinary stones is due to the fact that urea in human waste is converted into ammonia by microorganisms, and p
It is considered that this occurs because H increases and calcium ions in human urine are deposited as salts. It is considered that the sterilization of microorganisms in human waste inhibits the production of ammonia, and as a result, the generation of urinary stones can be suppressed. Further, as a result of the sterilization, even if urinary stones are deposited, the proliferation of microorganisms there is suppressed, so that it is considered that the generation of foul odors is effectively prevented.

Conditions such as electrolysis voltage and current may be appropriately determined within a range in which urinary stone precipitation is effectively prevented.
For example, 0.01-30g of hypochlorous acid by electrolysis
It is preferable to select the electrolysis conditions so that it is about / m 3 , preferably about 0.1 to 15 g / m 3 . If the concentration of hypochlorous acid is too low, the precipitation of urinary stones may not be sufficiently suppressed. In addition, if the concentration of hypochlorous acid is too high, for example, when human waste treatment is performed microbiologically, the residual hypochlorous acid in the circulated wash water will interfere with the growth of the microorganisms and This is because there is a risk of reducing the processing efficiency of.

発明において利用可能である。In the present invention, the human waste is exposed to the urine decomposition treatment means before being subjected to the electrolysis means so that the organic matter is decomposed and the molecular weight thereof is reduced. The human urine decomposition treatment means is not particularly limited as long as human urine can be decomposed to such an extent that it can be reused as purified water, but is preferably a physical or biological treatment, or a combination thereof. Here, the physical treatment includes, for example, photolysis by irradiation with ultraviolet rays, and the microbiological treatment includes, for example, degradation by an anaerobic or aerobic microorganism and a combination thereof. These physical or microbiological treatments can be used in the present invention as long as they are treatment methods that can be used in the field of human waste treatment, without essentially modifying them.

それがあるからである。According to a preferred embodiment of the present invention, the circulation purification apparatus according to the present invention preferably comprises means for solid-liquid separating the treated water before the treated water is electrolyzed. It is preferable that minute sludge particles in the treated water be removed by this solid-liquid separation means. When electrolyzed, if minute sludge particles and the like are present in the treated water, they may be attached to the surface of the electrode for electrolysis and reduce the electrolysis efficiency.

い。Further, according to a preferred embodiment of the present invention, in the circulation purification apparatus according to the present invention, when the human waste decomposition treatment means is a microbiological treatment, urine and washing water are introduced to the treatment means before washing water. It is preferable to include means for converting the residual hypochlorite ion into the organic chlorine compound. If hypochlorous acid and its derived hypochlorite ion (generally the combination of these is also called free chlorine) remain in the circulated and reused wash water, the urine and its washing as it is This is because when water is brought into contact with microorganisms, hypochlorous acid may inhibit the growth of the microorganisms and reduce the efficiency of human urine decomposition treatment. This conversion can be preferably achieved by storing a mixture of night soil and wash water for a certain period of time before performing biological treatment. Therefore, as a preferred specific example of the conversion means,
An example of the storage tank is provided before the means for decomposing human waste by biological treatment. According to a more preferred embodiment, this storage tank may have an aeration means so that the reaction of hypochlorous acid with an organic chlorine compound can be carried out more efficiently.

う構成されてもよい。Further, the circulation purification apparatus according to the present invention can be applied to both a urinal and a urinal, but can be more preferably applied to a urinal. In the case of a toilet bowl, the amount of wash water is large and the degree of dilution of human waste is high.
That is, the concentration of human waste is reduced, but in the case of a urinal, the amount of washing water is often smaller than that in the case of a toilet, and the concentration of human waste tends to be high. As a result, urinary stones may be significantly precipitated in the urinal and its piping. Therefore, for example, in the circulation purification device according to the present invention, the electrolyzed treated water may be reused only for the urinal.

In general, reuse of wastewater, so-called gray water, has a water quality standard for each application, and chromaticity is often one of the items. Here, the chromaticity is a numerical value indicating the degree of color of water.
The hue when 1 mg of platinum and 0.5 mg of cobalt in the chromaticity standard solution are contained in 1 liter is the chromaticity of 1 degree. For example, according to a certain standard, sprinkling water has a chromaticity of 50.
Hereinafter, it is said that it is preferable that the scenic water is 10 or less and the car wash water is 30 or less.

In the present invention, it is considered that the chromaticity can be effectively reduced because the chromophore is decomposed by hypochlorous acid generated in the treated water.

度は５度でほぼ一定となった。FIG. 4 is a correlation diagram between the concentration of hypochlorous acid and the chromaticity of the electrolytically treated water obtained as a result. When the hypochlorous acid concentration in the electrolytically treated water was 0, the chromaticity of the electrolytically treated water was 25 degrees. The chromaticity decreased with increasing hypochlorous acid concentration, that is, with increasing applied current. When the concentration of hypochlorous acid was about 0.2 mg / liter or more, no further decrease in chromaticity was observed even if the concentration of hypochlorous acid was further increased, and the chromaticity became almost constant at 5 degrees.
