この考案は微生物を利用し、処理槽内で汚水を
浄化するに際し、微生物床（ハニカムコア）へ処
理水を間欠的に送ることを目的とした汚水浄化装
置に関するものである。[Detailed description of the invention] This invention relates to a sewage purification device that uses microorganisms to intermittently send treated water to a microbial bed (honeycomb core) when purifying sewage in a treatment tank. be.
従来ハニカムコアを微生物床として汚水を浄化

常的に流動させる方式であるから、コアセルが詰
つたり、流動路が定まる為にハニカムコアの全域
を有効に利用し得ないなどの問題点があつた。 Devices that purify wastewater using a honeycomb core as a microbial bed are known, but most of them use a method in which the wastewater is constantly allowed to flow. There were problems such as the inability to use the system effectively.

この考案とは技術思想を異にしている。 In addition, a wastewater treatment method has been proposed in which a plurality of aeration means are distributed under a honeycomb core and the flow direction of treated water is changed by operating the aeration means under predetermined conditions. Tokuko Showa 56-23673
(No.), the rise of the treated water by the aeration means is relatively slow. Furthermore, according to the above-mentioned known example, there is a characteristic of changing the flow direction of the treated water, but this idea of changing the flow velocity periodically and suddenly in the same flow direction is different only in technical concept. figure,
The stimulus given to the microbial bed is also different. In addition, an invention has been proposed in which the jet water blown out from the nozzle is used to activate the microorganisms attached to the solid particles (Japanese Patent Laid-Open No. 103258/1983), but this invention does not use the jet water to simply stir the solid particles. It is only used for. Therefore, the technical idea is different from this idea which uses jet water for the circulation of all treated water.

である。 That is, to explain this invention with reference to an embodiment, a honeycomb core 2 is placed in the center of a processing tank 1 having a planar rectangular shape.
The cylindrical bodies 3, 3a are vertically installed in the honeycomb core 2 at a predetermined interval approximately at the center of the opposing long walls of the processing tank. The upper and lower ends of the cylinders 3 and 3a protrude slightly from the upper and lower surfaces of the honeycomb core 2, respectively, and a nozzle 4 is inserted into the center of the lower end of the cylinders 3 and 3a. Part 5 is on the way. The nozzle is connected to the tips of branch pipes 8, 8a connected to the discharge pipe 7 of the pump 6, and the bases of the branch pipes 8, 8a are connected to the discharge pipe 7 via a rotary valve 9. A worm wheel 11 is fixed to the valve rod 10 of the rotary valve 9, and the worm wheel 11 meshes with a worm 13 fixed to the shaft of a motor 12. Further, a suction pipe 14 of the pump 6 is connected to the processing tank 1. In the above, when wastewater is introduced into the treatment tank from the inflow pipe 16 as shown by arrow 15 in FIG. 1 and the pump 6 is started, the treated water in the treatment tank flows as shown by arrow 1
8, flows through the rotary valve 9 as shown by arrows 19 or 20, and reaches the blow-up tube 3.
Or rise from 3a. In the above, when the valve hole 22 of the valve body 21 communicates the discharge pipe 7 and the branch pipe 8 as shown in FIG. When communicating, it flows as shown by arrow 20, but in other cases, pressurized water does not come out from the nozzle, so the water in the blow-up cylinder inevitably rises rapidly intermittently. The water blown out from the upper ends of the blow-up tubes 3, 3a flows around the four circumferences as shown by arrows 23 and 24 in FIG. 1, descends inside the honeycomb core (arrow 25 in FIG. (arrow 26 in Figure 2) and rises again inside the blow-up tubes 3, 3a (second
Arrow 27 in the figure). In this way, the treated water is treated with microorganisms within the honeycomb core and is discharged from the discharge pipe 27. Although air is not actively supplied to the treated water in the above, the water rising in the blow-up tubes 3 and 3a is blown up above the water surface 28 and falls, naturally breaking into pieces and coming into contact with air, so that the treatment tank If the depth is not deep (for example, 2 to 3 m), there is no particular need for air supply.
If it is necessary to supply air, the gas-liquid mixture can be blown up from the nozzle to supply air by means such as connecting an air supply pipe 29 to the suction side of the pump. In the figure, 30 is a sediment discharge pipe.
前記実施例においてノズル４から加圧水を吹き
上げると、その上昇につれて吹上筒の下端からハ
ニカムの下部の処理水が吸い上げられる（第３図
中矢示３１，３２）。この場合に狭搾部５によ
り、上昇する処理水の流速は一層増大し、吸引効
果を益々向上する。 In the embodiment described above, when pressurized water is blown up from the nozzle 4, as the water rises, treated water from the lower part of the honeycomb is sucked up from the lower end of the blow-up cylinder (arrows 31 and 32 in FIG. 3). In this case, the narrowing portion 5 further increases the rising flow rate of the treated water, further improving the suction effect.
次に第６図は吹上筒内上部の流速の変化を示す

内の処理水は間欠的最高流速に達するような間欠
吹上げ状態を示すことになる。 Next, FIG. 6 is a graph showing changes in the flow velocity in the upper part of the blow-up cylinder. That is, when treated water is blown out from the nozzle, the flow velocity in the upper part of the blow-up cylinder reaches its maximum in t seconds (forced flow). Then, when blowing from the nozzle is stopped, the inside of the blow-up cylinder shifts from the forced flow to inertial flow, and the flow velocity slowly decreases. Then, when treated water is blown out from the nozzle again after t0 seconds, the flow shifts to forced flow again, and then the flow velocity changes as shown in FIG. 6 by repeatedly opening and closing the nozzle. Therefore, the treated water in the blow-up cylinder exhibits an intermittent blow-up state in which the flow velocity reaches the intermittent maximum flow velocity.
前記最高流速は、ノズルからの水量、水速およ

出し間隔を第６図中t0以上長くすると、ハニカム
コア内の処理水も断続流動となる。 The maximum flow rate is affected by the amount of water from the nozzle, the water speed, the diameter of the blow-up tube, etc., and the time to reach the maximum flow rate also varies, but by making the blowout from the nozzle intermittent, the flow rate of the treated water can be reduced. It is clear that it can be varied continuously. Note that if the interval between blowouts from the nozzle is increased by more than t 0 in FIG. 6, the treated water in the honeycomb core also becomes an intermittent flow.

を防止するなどの諸効果がある。 That is, according to this invention, a treatment tank is filled with a honeycomb core, and an intermittent blow-up tube for treated water is installed vertically inside the honeycomb core, so that the circulation of treated water is intermittent (or the amount of circulation changes intermittently). This has various effects such as preventing the generation of steady flow into the honeycomb core and preventing clogging in the core cells.
