Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a circulating type human waste treatment device which purifies the wastewater of human waste and domestic wastewater and reuses the water as toilet water, water for fire extinguishing, water sprinkling and the like at the level of middle water. It is useful for household septic tanks, small and medium-sized septic tanks, temporary installation for construction / events, or septic tanks / public toilets in places where water is not drained.

[0002]

[Prior art]

 Conventional septic tank treatment involves precipitation, separation, and then contact aeration using an artificial filter medium. In this case, the unpurified urine could not be sufficiently purified, and the purified water had a high BOD value and a high PH, and thus was not usable as water at the level of the water supply system. In addition, there is a septic tank that uses abacus as a contact material to perform aeration treatment to increase the purification power and bring the treated water closer to neutrality.However, aeration treatment using only a cask requires transparency, decolorization and deodorization. Is insufficient, and because many husks are exhausted, the number of times husks are replenished increases, running costs increase, and it takes about 3 months to start up before normal use after the septic tank is installed. There was a problem that became.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve these conventional problems, to lower the BOD value of treated wastewater, to neutralize the treated water, and to decolorize and deodorize the treated water to make it transparent. It can be treated at a high level, can be used at a low cost, has a low running cost, can be quickly started up during installation, and can be put into normal use in a short period of time. The purpose is to provide a circulating type human waste treatment device that enables circulation.

[Embodiment of device]

 According to the present invention, wastewater discharged from the toilet or domestic wastewater discharged from the kitchen, etc. flows into the sedimentation separation chamber, and solids, plastics, rubber articles, metal pieces, etc. in the wastewater are stored in the room. It settles on the floor surface, part of which floats on the liquid surface, and the components of wastewater are solid-liquid separated. The liquid of the sewage that has been solid-liquid separated flows into the anaerobic filter chamber, and the sewage is anaerobically decomposed by microorganisms using the porous artificial filter medium as a contact material. The sewage that has been anaerobically decomposed in the anaerobic filter chamber flows into the contact aeration chamber and is aerobically decomposed using the chaff as a contact material. In the contact aeration chamber, the aeration process is performed by using the oyster shell as a contact material, and the sewage is alkalized by the oyster shell to make it close to neutral, and the aeration process is efficiently performed aerobically on the porous surface of the oyster shell. Well decomposes and purifies sewage. The wastewater that has been decomposed and purified in the contact aeration chamber is purified to a BOD value of 5 PPM or less, and is neutralized to near PH7. After that, the water in the contact aeration chamber flows into the finishing treatment chamber, comes into contact with the activated carbon, decolorizes and deodorizes the water, and becomes transparent and neutral with a BOD value of about 5 to 1 PPM, and passes through the water supply channel to the tank of the tray. Sent for reuse as toilet water. In the present invention, by using oyster shells, high decomposition and purification power and neutralization can be obtained, but by not using all oyster shells for purification, the usage amount of oyster shells can be reduced. , Reduce the consumption of husks and reduce the number of refills. Also, by adding anaerobic filter purification, the quality of decomposition and purification is improved so that even those that are difficult to decompose by aerobic aeration can be sufficiently decomposed.

Accumulate, and a part floats on the liquid surface. Also, part of the wastewater begins to decompose by microorganisms. The sewage liquid that has undergone solid-liquid separation in the settling separation chamber 3 moves to the inside of the guide 12 and prevents the floating solids from entering the sewage overflow part 11 at the upper end of the partition wall 10 which is anaerobic. Transfer to filter bed room 4. The sewage flowing into the anaerobic filter chamber 4 comes into contact with Nittetsu Krisvar (trademark), which is a porous granular material obtained by specially processing amorphous silicic acid and crystalline silicic acid, and the anaerobic breeding on the same day iron krisvar. It is effectively and well decomposed by sex bacteria. The well-anaerobically decomposed sewage flows into the contact aeration chamber 5 from the overflow portion 19 of the partition wall 18. In the contact aeration chamber 5, air is blown into the contact aeration chamber 5 in the form of bubbles from the lower air diffuser 14 to cause convection of sewage in the contact aeration chamber 5, and the sewage is aerated with the aerobic bacteria of the cask of the contact material 17.

The water in the finishing treatment chamber 6 that has been purified to the extent that it can be used as tap water is pumped up by the water supply pump 28, sent to the tank 9 of the toilet 8 via the water supply pipe 7, and used as toilet water. Further, the water in the finishing treatment room 6 is pumped up by the submersible pump 29 and is also used for garden water and fire extinguishing water so that when the water becomes large, it can be discharged to rivers and sewers. In addition, by using the oyster shell as the contact material 17, the purification power at the start of human waste treatment can be quickly raised, and the startup at the time of installation can be done in a short number of days. In addition, by using two types of contact materials, the oyster shell and the artificial filter medium, the consumption of the oyster shell can be reduced and the running cost can be reduced. Further, since the purified water is returned to the tank 9 of the toilet 8 and can be reused as the tap water, the amount of water supplied from the outside of the toilet water can be considerably reduced and the water consumption can be reduced. In addition, it can be easily installed in places without water supply and drainage facilities, such as civil engineering construction sites, parks, farmland, and mountainous areas.

[Effect of device]

 As described above, according to the present invention, by combining the decomposition by the anaerobic filter bed with the porous artificial filter medium, the contact aeration by the chaff, and the advanced treatment with the activated carbon, the wastewater is removed. By purifying it until it can be used as tap water, and by reusing it as toilet water, it can reduce the consumption of toilet water, have a water-saving effect, and treat it without discharging it, resulting in river pollution and human waste. The amount of pumping can be greatly reduced. In addition, it can be used in places where it is not possible to drain water or where it is difficult to receive a large amount of water, such as construction sites, parks, event venues, and mountainous areas.
