BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aeration treatment facility for organic matter-containing sewage for treating organic matter-containing sewage, such as household wastewater, sewage, or wastewater from a food processing plant, by contacting with bubbles in a drip tank or by activating aerobic bacteria.

In conventional sewage treatment facilities, generally, organic matter-containing sewage is supplied intermittently into the sump tank, and air is supplied to an acid pipe piped to the lower part of the sump tank to pass many bubbles from the acid pipe into the sewage tank. In this way, the organic matter suspended in the sewage is concentrated in a lump form by contact oxidation to float or subside to purify the sewage with aeration. The diffuser is usually forced to send air from a Roots blower. Recently, in order to increase treatment efficiency, a water treatment apparatus using ozone foam flotation separation has been proposed, in which ozone having high oxidation capacity is added to the air from the blower to be added to an acid pipe after it is generated and added to the diffuser (for example, a patent). See Document 1).

[Patent Document 1] Japanese Patent Publication No. 2003-225654

In addition, conventional treatment of organic matter-containing wastewater includes nitrogen oxides contained in organic wastewater such as sewage, excreta, and various industrial wastewaters, while being flowed upstream in an anaerobic drip tank having a particulate sludge phase of methane fermentation bacteria. There is a biological denitrification method which propagates around the particulate sludge, biologically reduces and denitrates (see Patent Document 2). This allows the cells to be granulated to maintain the cells at a high density, so that they can be operated under high load.

[Patent Document 2] Japanese Patent Application Laid-Open No. 7-290088

The first water treatment device by separating the ozone foam float is to introduce an index containing interlaced matter such as Aoko intermittently into the drip tank, and to separate the float floating foam while performing aeration using low concentration ozone, effectively By the oxidation treatment, suspended solids such as Aoko are concentrated in a lump shape to be separated from the index. However, since ozone generators generate ozone by discharging in the air therein, a large amount of electrical energy is required to treat a large amount of sewage.

In the above-mentioned second biological denitrification method, the suspended organic matter itself is a granular material or flake of several mm to 0.1 mm, and even in the state of uniform fine particles acting on it, even if high density contact is attempted, the working effect is limited. On the other hand, since sludge accumulates relatively quickly so that fine sludge of denitrifying bacteria can form in a short time and maintain a stable fine particle sludge phase, treatment of the sludge is also an important problem. In addition, the floating organic matter of the to-be-processed object is also subject to not only anaerobic treatment but also to aerobic treatment to achieve rapid disappearance of the organic matter.

The first object of the present invention is to treat the bubbles introduced into the jet using the high speed water flow generated by the pump to ultra-fine by high speed water flow in the annular flow passage formed of a plurality of passage walls, and to contain the ultra fine bubbles. Can be supplied into the drip tank to efficiently treat the suspended organic matter in the sewage by catalytic oxidation, thereby greatly increasing the treatment capacity, and the organic energy-containing sewage treatment facility is relatively low in energy consumption and extremely simple in structure. To provide.

The second object of the present invention is to quickly and rapidly decompose organic matter in the waste water by aerobic bacteria in the state of the first high dissolved oxygen, and then biodegrade in the circulation process by anaerobic bacteria in the state of oxygen consumption. At the same time, the sludge flowing at a high speed of at least 8 m / sec generated by the facilities for treating organic matter-containing sewage, which can be biodegradable and activated sludge produced in the biodegradation process, and particularly a high-pressure pump, can be efficiently used. The microscopic water clusters and organic matters are also micronized by at least shear action occurring in the annular flow channel, and the microorganisms efficiently and efficiently process suspended organic matter of extremely large surface area per unit weight by microorganisms in a very short and efficient time. This can greatly increase the processing capacity of organic matter in the drainage. Provides microorganism-containing sewage treatment facilities that greatly reduce or extinguish sediments, such as sludge, by destroying the cell membranes of activated sludge microorganism carcasses generated by biodegradation and treating the cytoplasm with microorganisms. will be.

The present invention has a supply portion for supplying sewage including suspended organic matter such as household wastewater and a discharge portion for discharging purified water, and the floating organic matter in the supplied sewage is contacted and oxidized by bubbles discharged from the lower portion to concentrate in a lump shape. Or a sink to sink and purify sewage,

The treatment water supply device has an air inlet for introducing air as bubbles to the water flow supplied at a high speed from the water inlet, and the high speed water flow is supplied at a flow rate of at least 8 m / sec in a ring-shaped flow path defined by a cylinder wall in the casing of the apparatus. In addition, the water cluster is ultra-fine by the impact force at the flow direction changing portion, the shear force at the tube wall surface, and / or the cavitation effect, and the air bubbles introduced at the same time are contained in the water stream.

The treatment water supply device forms an outer wall of the casing in a cylindrical shape, and spaces the inner cylindrical wall eccentrically to form a flow path concentrically or without contact between the walls of the casing. By combining the cylindrical wall with the casing bottom wall and forming a gap with respect to the casing ceiling wall, the annular flow path formed by the cylindrical outer wall and the inner cylindrical wall and the inside of the inner cylindrical wall communicate with each other through the gap. By the first high-speed water flow of bubble mixing from the first water introduction portion to the interior of the inner cylindrical wall, followed by being sucked by the second pump from the interior of the inner cylindrical wall and discharged at high speed to be formed. A high velocity water stream is supplied from the second water inlet to the annular flow path and then from there to the top of the inner cylindrical wall. It rapidly falls and collides with the casing bottom wall, thereby minimizing the water cluster in the circulation flow path formed over the inside of the annular flow passage and the inner cylindrical wall, and at the same time, making the air bubbles in the water flow very fine, and making a very fine bubble. The treated water may have a structure in which a portion of the treated water is removed from the annular flow passage and supplied to the diffuser of the drip tank.

The treatment water supply device forms the outer wall of the casing in a cylindrical shape, and separates two walls of the intermediate cylindrical wall and the inner cylindrical wall in an eccentric shape so as to form a flow path concentrically or without contact between the walls of the casing. The intermediate cylindrical wall is joined to the casing ceiling wall and the casing bottom wall to form an outer annular flow path, the inner cylindrical wall is combined with the casing bottom wall, and the gap is formed with respect to the casing ceiling wall, The intermediate annular flow path formed by the cylindrical wall and the inside of the inner cylindrical wall communicate with each other through the gaps.

On the other hand, in the first water introduction portion in the water introduction portion, the first high speed water flow generated by the first pump is supplied to the air introduction portion, where air is introduced as a bubble into the first high speed water flow, and the bubble is introduced. The first high velocity water flow is supplied to the intermediate annular flow path, and then rapidly falls from the upper end of the inner cylindrical wall to the casing bottom wall to collide with the casing bottom wall, and from the inside of the inner cylindrical wall to the second pump. The second high velocity water stream is sucked by and discharged at a high speed to be supplied from the second water introduction portion to the outer annular flow path, and the outer annular flow path is connected to the suction side of the first pump through a conduit. And a shear action in the intermediate annular flow passage and the outer annular flow passage constituting the circulation passage. The collision to the thin bottom wall makes the water cluster ultrafine and the bubbles in the water stream ultrafine, so that the treated water containing the ultrafine bubbles partially escapes from the outer annular flow passage and is supplied to the diffuser. have.

The air inlet is constituted by a blower using a high speed water flow, and is provided at a height corresponding to the surface of the sewage in the drip tank.

The high speed water flow supplied into the annular flow path defined by the passage wall inside the device casing is supplied from the tangential direction to the annular flow path, and the water flow supplied at high speed from the first water inlet is supplied with sewage in the drip tank. It is formed.

In addition, the passage wall may have a curvature change part such as a flat part.

It is preferable to connect the following biodegradation treatment facilities to the above treatment facilities. This treatment facility is provided with sewage containing organic matter, such as sewage or wastewater from food processing plants, through the conduit from one side, and treated water from which organic matter has been at least partially removed through the conduit from the other side. A housing having at least a circumferential wall and a bottom wall with recessed points,

The microorganism is mounted downward from the upper end of the housing so that the feed sewage can be introduced into the housing, and has a plurality of passages communicating in the vertical direction. The processing means being formatted,

The sewage supply to raise and circulate a plurality of bubbles from below in the interior of the housing adjacent to the sewage supply conduit, while allowing the descending supply circumference to rise, thereby promoting and circulating the inflow from above into the treatment means. An organic material-containing sewage treatment facility characterized by comprising an air pipe connected adjacent to a conduit.

The organic matter-containing sewage causes a high-speed swirl flow of at least 8 m / sec in the annular space between the outer cylinder and the inner cylinder, and the organic matter by an ultra-fine device for ultrafine processing to a micron level by at least shear action of the high-speed swirl flow. After the ultrafine water clusters have been micronized, they are once received in a drip tray and then fed to a treatment plant that performs biodegradation at a relatively slow rate.

The housing is an upwardly open housing having a bottom wall with the dents forming a pyramidal shape and a circumferential wall forming a substantially rectangular cross section, wherein the sewage supply conduit is disposed in the vicinity of one corner, and the treatment The water discharge conduit is disposed in the vicinity of the corner facing the sewage supply conduit, and a conduit for discharging sediment such as sludge accumulated at the bottom of the concave portion is connected.

The discharge conduit of the sediment has an open / close valve that is regularly opened or closed at all times during operation, and the sediment is once collected in the tank and then ultra-fine by the ultra-fine device supplied from the tank and immediately after or Once received in the drip tank, it is returned to the treatment facility.

The treatment means includes a porous membrane in which aerobic bacteria inhabits, a porous membrane in which anaerobic bacteria inhabits, and / or a filler in which microorganisms are filled in the passage, and at least the other side of the housing A support frame for supporting the treatment means seen from the circumferential wall, and supports the treated water discharge conduit opened at the lower end of the treatment means by the support frame.

This treatment facility is installed in multiple connection with the treatment facility discharge conduit, which is the front facility, connected to the wastewater supply conduit, which is the rear facility, and the wastewater supply conduit, the first facility, receives sewage from the drip tank and discharge the treated water, the last facility. The conduit is piped to discharge the treated water to the drip tank or to the stream or the like.

The ultra-miniaturization apparatus is connected to the drip tank or the tank, and forms a casing with an outer cylinder, and spaces the inner cylinder with an eccentric shape such that the casing is formed concentrically or without contact between the cylinders. By combining the inner cylinder with the casing bottom wall and forming a gap with respect to the casing ceiling wall, the annular space formed by the outer cylinder and the inner cylinder and the inside of the inner cylinder communicate with each other through the gap. Is supplied from the drip tank or the tank to the interior of the cylinder by a first high speed water stream containing precipitates such as organic matter or sludge, which is then sucked by the second pump from the interior of the cylinder and discharged at high speed. And a second high velocity water stream is supplied from the second water inlet to the annular space, It falls sharply from the upper end of the said cylindrical body to the inside, and makes it collide with the casing bottom wall. On the other hand, in the circulation flow path formed over the annular space and the inner cylinder, the sludge microorganisms of the sludge microorganisms in the water stream or the sediment are destroyed, and the treated water in which the organic matter or precipitate is ultrafine is partially removed from the annular flow path. It may have a structure to discharge to the drip tank or the tank.

The ultra-fine device is fluidly connected to the drip tank or the tank, and forms the outer wall of the casing into an outer cylindrical body, and eccentrically so as to form a flow path concentrically or without contact between the walls of the casing. Two cylindrical bodies and cylindrical bodies are arranged together, and the intermediate cylindrical body is combined with the casing ceiling wall and the casing bottom wall to form an outer annular space, the inner cylinder is combined with the casing bottom wall, and the gap between the casing ceiling walls is also provided. By forming, the intermediate annular space formed by the intermediate cylinder and the inner cylinder and the inside of the inner cylinder communicate with each other through the gap, and also the organic matter generated by the first pump at the first water inlet from the water tank and the tank. Or a first high velocity water stream containing a precipitate such as sludge is supplied to the ejector of the air inlet, where Air is introduced into the first high velocity water stream as a bubble, and the first high velocity water stream into which the bubble is introduced is supplied to the intermediate annular space, and then is rapidly dropped from the upper end of the inner cylinder to the inside of the casing bottom wall. And a second high speed water stream drawn by the second pump from the inside of the inner cylinder and discharged at a high speed to be supplied from the second water inlet to the outer annular space, and the outer annular space Is connected to the suction side of the first pump through a conduit, and a flow path is formed, and a shear action in the intermediate annular space and the outer annular space constituting the circulation path and a collision with the casing bottom wall Ultrafine microorganisms by destroying sludge microbial cell membranes in organic matter or sediment in water It is treated containing a precipitate, such as water or sludge, some fall from the outer annular space may have a structure that is introduced into the water receiving tank or the tank.

The high-speed water flow supplied into the annular space defined by the cylinder wall inside the apparatus casing is supplied from the tangential direction to the annular space.

When the outer wall of the casing of the treated water supply device is formed in a cylindrical shape, and the inner cylindrical wall is arranged eccentrically so as to form a flow path concentrically or without contact between the walls of the casing, a ring is formed between the outer wall and the inner cylindrical wall. The flow path is formed, and the high-speed water flow is always changed to generate a strong centrifugal force, so that it strongly touches the outer wall surface to generate a shear force between the large compressive force and the laminar flow, and at the same time to remove the laminar flow from the inner wall surface Cavitation can be produced | generated, and the ultrafineness of a bubble can be accelerated | stimulated. In the circular annular flow path, it is relatively easy to maintain the flow rate of the water flow. In addition, by connecting the inner cylindrical wall to the casing bottom wall and forming a gap with respect to the casing ceiling wall, the annular flow path formed by the cylindrical outer wall and the inner cylindrical wall and the inside of the inner cylindrical wall communicate with each other through the gaps, At the same time, the water flow supplied from the annular flow path and from the first pump falls into the inner cylindrical wall and collides with the casing bottom wall, thereby facilitating ultra miniaturization of the water cluster and bubbles by the impact force. Moreover, since water is sucked in from the inside of the inner cylindrical wall by the second pump, the impact force of the water flow falling into the inside can be made stronger. The second high speed water flow drawn by the second pump and discharged at a high speed is supplied to the annular flow path, thereby forming a circulation flow path inside the annular flow path and the inner cylindrical wall, and is repeated during circulation. It is possible to carry out ultrafine micro bubbles and micro bubbles in water flow. The treated water containing the micronized bubbles is partially removed from the annular flow path and supplied to the diffuser.

If the outer wall of the casing of the treated water supply device is formed in a cylindrical shape, and the middle and the inner cylindrical wall are arranged so as to form a concentric shape or a flow path without contact between the walls of the casing, the inner, outer and inner cylinders Between each cylindrical wall of the outer and intermediate ring-shaped flow path is formed. The high-speed water flow supplied to these outer and intermediate annular flow paths always changes the flow direction and generates a strong centrifugal force, which strongly contacts the outer wall surface to generate shear force between the large compressive force and the laminar flow, and at the same time, the laminar flow separation from the inner wall surface. It can cause the cavitation action to promote the ultrafine bubbles. In the circular annular flow path, it is relatively easy to maintain the flow rate of the water flow. In addition, when the intermediate cylindrical wall is combined with the casing ceiling wall and the casing bottom wall, and the inner cylindrical wall is combined with the casing bottom wall to form a gap with respect to the casing ceiling wall, the water flow supplied to the intermediate annular flow path is the upper end of the inner cylindrical wall. It rapidly falls from the inside to the inside of the casing, and the impact force generated by colliding with the casing bottom wall promotes the ultra miniaturization of the water cluster and the bubbles. The introduction of air bubbles into the water stream is effected by the ejector action using the first high speed water flow generated by the first pump at the air introduction portion of the first water introduction portion in the water introduction portion. The first high velocity water flow into which the bubble is introduced is supplied to the intermediate annular flow path, and then continuously drops from the upper end of the inner cylindrical wall to the inside and collides with the casing bottom wall as described above, but inside the inner cylindrical wall. Since it is sucked by the 2nd pump from the inside, the said impact of the water flow which falls inside can be made stronger. The second high speed water flow sucked by the second pump and discharged at high speed is formed to be supplied to the outer annular flow path at the second water inlet, and is also supplied through the conduit from the outer annular flow path to the suction side of the first pump. A circulation path is formed. By repeating the cycle, ultrafine clusters and ultrafine bubbles in the water stream can be achieved. The treated water containing the micronized bubbles is partially removed from the outer annular flow path and supplied to the diffuser.

The air introduction section is composed of a jet using high speed water flow, and can suck air into the water stream by the negative pressure generated by the high speed water flow emitted from the nozzle of the jet without using an air pump.

The air introduction portion is provided at a height corresponding to the surface of the sewage in the sump tank, and offsets the pushing resistance corresponding to the head of the sewage in the sump tank, thereby reducing the power supply of the treated water.

The high-speed water flow supplied into the annular flow path defined by the passage wall inside the apparatus casing is supplied from the tangential direction to the annular flow path, thereby smoothly supplying the water flow into the annular flow path to prevent the fluctuation of speed, and the high-speed water flow throughout the entire path. It helps to maintain the above action.

The water flow supplied at high speed from the first water inlet is formed by the supply of sewage in the drip tank, and the treated water supply device sucks the sewage out of the drip tank without requiring a new constant, thereby minimizing water clusters and bubbles. At the same time, ultrafineness of the suspended organics in the sewage can also be carried out, and the catalytic oxidation can be greatly promoted.

If the cylindrical wall partially has a curvature change portion such as a flat portion, the flow rate of water decreases slightly in the curvature change portions, but the direction of the water flow is changed to increase the shear force acting between the water flow layers.

Further, as a second effect, in a treatment facility for organic matter-containing sewage, at least inside the housing having a bottom wall having a perimeter wall and a recessed portion, the sewage supplied from one side of the housing can flow from the top to the bottom thereof from above. Sewage supplied from the sewage supply conduit because the processing means is mounted, and the processing means has a plurality of fine passages communicating in a number of vertical directions, and inhabits the microorganisms for biodegrading organic matter in the influent sewage. Is raised by a plurality of bubbles from the air pipe piped adjacent to the conduit and contains a large amount of air, and then flows from the top to the processing means to promote circulation, and is preferably caused by the microorganisms during the descending of the plurality of passages. Efficient by aerobic bacteria in the airy upper part and anaerobic bacteria in the lower air part The biodegradation process is carried out rapidly. In this way, if sewage containing organic matter such as wastewater from a sewage or food processing plant is supplied to the inside through a conduit from one side of the housing, the treated water at least partially extinguished by the processing means as described above is directed to the other side. Partial emissions through the conduit from this (this emissions and emissions from the bottom wall with recessed points correspond to the supply). As for the treatment means, the size (treatment capacity) and flow rate are determined according to the type or amount of organic matter in the sewage.

The filthy water containing the organic matter causes a high speed swirl flow of at least 8 m / sec in the annular space between the outer cylinder and the inner cylinder, and ultrafine treatment to the micron level by at least shear action of the high speed swirl flow. After the ultrafine organic matter and water clusters are supplied to the facility, the organic matter is ultrafine, and the unit surface area (specific surface area mm ² / g) is greatly increased. Furthermore, when the 1mm diameter spherical organic matter is ultrafine, Since it has a specific surface area of 10,000 times and the water cluster is also very fine, it spreads well so that the treatment efficiency by microorganisms is significantly increased, and rapid treatment is achieved. In addition, since the ultra-fine water flow is made of a high speed water flow, it is once received by the drip tank to weaken the momentum of the water flow and then supplied to the treatment facility at a relatively low speed suitable for biodegradation treatment.

The housing is an upwardly open housing having the bottom wall with the recessed portion and the pyramid-shaped circumferential wall forming a substantially rectangular cross section, so that one side is the wastewater supply side and the sewage supply conduit At the same time, the treated water discharge conduit can be arranged near the corner opposite the opposite side, and the treatment means can be effectively used in response to the diffusion of the treated wastewater. In addition, sediments such as activated sludge generated by biodegradation can be accumulated at the bottom of the cut-out and can be discharged to the conduit from there.

The discharge conduit of the sediment has an opening / closing valve such as a solenoid valve that opens and closes regularly, thereby setting the opening / closing timing according to the accumulation rate, and collecting the precipitate once in the tank. If the precipitate is organic matter such as activated sludge, it is supplied from the tank to the ultra-fine device and ultra-fine, and after the ultra-fine, the water flow is weakened and returned to the biodegradation facility immediately, or once collected in the drip tank, It can be returned to the decomposition treatment plant for destruction. If the precipitate is a non-corrosive mineral, it can be landfilled. It is also possible to operate the on / off valve at all times during operation to collect the sediment once in the tank and continuously supply it to the ultrafine device.

The treatment means has a porous membrane in which aerobic bacteria are inhabited thereon, a porous membrane in which anaerobic bacteria are inhabited therein, and a support frame for supporting the treatment means as seen from at least one peripheral wall of the housing, It is possible to secure a space for generating a flow of upflow due to the supply of sewage and a plurality of bubbles from the air supply pipe on one side, and in the lower part where air is consumed by aerobic bacteria inhabiting a fine passage and a porous membrane in the upper part containing a lot of air. Anaerobic bacteria inhabiting the fine passage and the porous membrane can be effectively biodegraded by a large number of microorganisms, respectively, in a suitable environment. The support frame can be equipped with a porous membrane in which aerobic bacteria live or a porous membrane in which anaerobic bacteria live. Also, by filling a filler filled with microorganisms in the passage of the treatment means, the descent flow rate is weakened, thereby achieving dense contact with the microorganisms. can do.

The biodegradation treatment plant is provided with a plurality of connected water discharge conduits, which are the front equipment, connected to the sewage supply conduit, which is the rear equipment, and the sewage supply conduit, which is the first equipment, receives the sewage from the drip tank, When the treated water discharge conduit is piped to discharge the treated water to the drip tank, the plurality of facilities can be connected and installed according to the degree of contamination by organic matter to completely dissipate the organic matter in the sewage.

The ultrafine facility is connected to a drip tank or the tank, and can be repeatedly ultrafine by sucking water containing organic matter therefrom and returning it after ultrafine. In addition, when the inner cylindrical wall is arranged concentrically in the casing of the outer cylindrical body or in an eccentric shape such that a flow path is formed without contact between the cylindrical walls, a ring-shaped space is formed between the outer cylindrical body and the inner cylindrical body. The high-speed water flow supplied always changes the flow direction to generate a strong centrifugal force, which is strongly in contact with the inner surface of the outer cylinder to generate a shear force between the large compression force and the inner laminar flow, and at the same time the cavitation from the inner surface of the inner cylinder This can promote ultrafine water clusters and organic matter, cell membrane destruction of sludge microorganisms and ultrafine cytoplasm. In the circular annular space, it is relatively easy to maintain the flow rate of the water flow. Further, by coupling the inner cylinder to the bottom of the outer cylinder and forming a gap with respect to the ceiling wall of the outer cylinder, the annular space formed by the outer cylinder and the inner cylinder and the inside of the inner cylinder are opened through the gap. Through this, high-speed water flow drops from the annular space and at the same time from the first pump, falls into the inner cylinder, collides with the bottom wall, and accelerates the water cluster and the ultra-fineness of the organic matter or sludge by the impact force. . In addition, since water is sucked from the inside of the inner cylinder by the second pump, the impact force of the water flow falling into the inside can be further strengthened. The second high speed water flow drawn by the second pump and discharged at a high speed is supplied to the annular space, thereby forming a circulation passage through the annular space and the inner cylinder body, thereby repeatedly minimizing the cycle. Can be done. Treated water containing ultra-fine organics or sludge is partially removed from the annular space and fed to the sump tank.

The ultrafine device is connected to the drip tank or the tank, and can be repeatedly ultrafine by sucking water containing organic matter therefrom and returning it after ultrafineness. In addition, when the casing of the ultra-miniaturization device is formed with an outer cylindrical body, and the intermediate and internal cylindrical walls are arranged in an eccentric shape such that the casing is formed concentrically or without contact between the cylindrical walls, the intermediate, internal and internal cylinders An outer and intermediate annular space is formed between each cylindrical body. The high-speed water flow supplied to these outer and intermediate annular spaces always changes the flow direction to generate a strong centrifugal force that strongly contacts the outer wall of each annular space, causing shear force between the large compressive force and the laminar flow of the wall. Laminar flow peeling is caused from the inner wall surface to generate a cavitation action, thereby facilitating ultrafineness of organic matter and sludge in the drainage, that is, destruction of cell membranes of microorganisms in sludge and ultrafineness of the cytoplasm. In the circular annular space, it is relatively easy to maintain the flow rate of the water flow. In addition, when the intermediate cylinder is coupled to the casing ceiling wall and the casing bottom wall, the inner cylinder is combined with the casing bottom wall, and a gap is formed with respect to the casing ceiling wall, the water flow supplied to the intermediate annular space is from the top of the cylinder body. It rapidly falls into the interior, and the impact force generated by colliding with the casing bottom wall promotes the ultra miniaturization of the water cluster and organic matter or sludge. The introduction of bubbles into the water flow is performed by a suction action using the first high speed water flow generated by the first pump in the air introduction portion of the jet of the first water introduction portion in the water introduction portion. The air absorbed by the water strongly causes the above cavitation action or activates the aerobic bacteria of the treatment means. The first high velocity water stream into which the bubble is introduced is supplied to the intermediate annular space, and then as described above, it rapidly falls from the upper end of the inner cylinder and collides with the casing bottom wall, but is removed from the inside of the inner cylinder. Since it is attracted by 2 pumps, the said impact of the water flow which falls inside can be made stronger. The second high speed water flow sucked by the second pump and discharged at high speed is formed to be supplied to the outer annular flow path at the second water inlet, and is further supplied from the outer annular flow path through the conduit to the suction side of the first pump. A circulation path is formed. By repeating the cycle, ultrafine water clusters and ultrafine organic matter or sludge can be carried out to a desired degree. Treated water containing ultra-fine sludge is partly drained from the outer annular flow channel and fed to the sump tank.

The high speed water flow supplied into the annular space defined by the cylindrical body inside the apparatus can be supplied from the tangential direction to the annular space to reduce the loss of the inflow velocity, thereby generating a high speed swirl flow.
