The present invention facilitates the collection and treatment of the wastes by discharging fine bubbles to the wastewater introduced into the purification treatment tank in the wastewater purification device so as to injure large and small wastes contained in the wastewater. At the same time, the present invention relates to a bubble generating device for a gas-liquid mixer of a waste and waste water purification device, which enables to increase the amount of dissolved oxygen and to purify the waste water more efficiently.

In general, there are various methods for purifying sewage and wastewater, including contacting mesh media with microorganisms, filtering wastewater by sending the wastewater to a screen device, and aggregating and immersing foreign matter using chemicals. Among them, as a method of supplying air into the water to increase oxygen dissolved amount and allowing bubbles to float, foreign substances were purified as shown in FIG.

The conventional purification treatment apparatus as shown in FIG. 5 has an inlet pipe 101 for introducing wastewater into the upper portion of the purification treatment tank 100, and a chain that is rotated by being rotated by the driving and interlocking chain gears 102 and 103. A collection device for attaching a plurality of collection plates 105 to the collection 104 to collect the injured injuries on the water surface, a pressurized tank 107 provided separately from the purification tank 100, and the pressurized tank 107 A circulation pipe 109 for pumping and supplying water from the purification tank 100 as a pump 108, a compressor 110 that is separately installed to supply compressed air to the pressure tank 107, and the pressure tank ( An injection valve 112 is provided in the supply pipe 111 for supplying the compressed air and water pressurized by the 107 to the purification treatment tank 100. When pressurized water and air are injected through the injection valve 112, bubbles are generated to increase the amount of dissolved oxygen. With it was configured to be contained in the wastewater treated by the foreign matter to the surface portion that by the air bubbles.

However, since the conventional purification apparatus has to install a device other than the purification treatment tank 100, that is, the pressure tank 107 and the compressor 110 and its accessories, the installation cost is not only high but also takes up a lot of installation space. In addition, there is a problem in that the consumption of power is too large to maintain the compressor 110 and the pressurized tank 107 is too large, such a conventional purification device is pressurized water and air in the pressurized tank 107 When the mixture is mixed under the state and injected into the inner bottom of the purification tank 100 through the injection valve 112, since the bubbles generated by the injection pressure are relatively large, the dissolved oxygen increase effect and the foreign matter floating effect are insufficient. Was showing.

In addition, after attaching the air induction pipe to the motor and attaching a rotary blade to the lower air induction pipe, the rotary wing rotated by the rotational force of the motor is introduced into the air induction pipe by the centrifugal force acting to drive water out Although a gas-liquid mixer has been proposed to break bubbles when air is discharged into water, it is difficult to increase the amount of dissolved oxygen because the size of the bubbles discharged from the rotor blades submerged in water is relatively large. However, if the bubble is large, there is a disadvantage that the density of bubbles is not dense, so that the floating action of foreign matters is lowered, so that the removal effect of foreign matter contained in the waste water is low. In particular, the conventional gas-liquid mixer is in water. There was a problem that the length is limited because the immersed rotor blade portion can not hold.

The present invention was devised to solve the conventional problems as described above, and does not install an accessory device such as a pressurization device or a compressor separately from the purification treatment tank, and uses only the existing gas-liquid mixer to remove the wastewater introduced into the purification treatment tank. It was designed with the purpose of increasing the amount of dissolved minerals and increasing the by-products of foreign substances, so that the waste water can be more efficiently purified.

The present invention is a means for achieving the above object, the separator is installed to separate the inside of the purification treatment tank into a waste water inlet and a treatment water discharge, the inlet pipe is installed in the waste water inlet, discharged treatment water The unit is provided with a collection device connected to a chain having a large number of collection plates attached to the drive and interlocking chain gears to generate bubbles at the wastewater inlet and to collect the suspended matter at the wastewater outlet. In the purification device, the rotation is freely installed inside the fixed tube, and a well-known gas-liquid mixer having a plurality of air discharge holes and rotary blades formed at the end is attached to the support upper plate above the waste water inlet and then the gas-liquid. The rotary blade part of the mixer is fixed to the base fixed at the bottom of the wastewater inlet, and a lot of bubble grinding holes formed of thin and long holes are formed. It is characterized in that it is installed inside the bubble generating container.

Referring to the accompanying examples of the present invention in detail as follows.

FIG. 1 is a state diagram of a gas-liquid constituting machine for explaining the present invention, FIG. 2 is a cross-sectional view showing an operating state of the present invention, and FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and (a) (b) of FIG. (c) is a diagram showing the structure of the bubble grinding hole of the bubble generating cylinder, which is the main part of the present invention, the reference numeral 1 denotes a purification tank, the interior of the purification tank (1) has a membrane (2) The waste water inlet portion (3) and the treated water discharge portion (4) is divided into, and the upper part of the partition (2), the wastewater and suspended matter introduced into the wastewater inlet portion (3) is overflowed and treated It is configured to be low so as to move to the water discharge unit 4, and the lower end of the partition was opened so that the waste water inflow unit 3 and the treated water discharge unit 4 communicate with each other.

The waste water inlet (3) is provided with an inlet pipe (5) for introducing the waste water, and the drive water and interlocking chain gear (6) rotated by a motor above the treated water outlet (4) ( A collection device is provided with a plurality of collecting plates 9 attached to the chain 8, which is addressed in 7). The collecting plates 9 continuously scrape the floating matter floating on the surface when moved to the lower side. By collecting in the furnace 10 it was possible to process the suspended matter.

The support top plate 11 is installed above the wastewater inflow portion 3, and an existing gas-liquid mixer 12 is installed. The gas-liquid mixer 12 is a support cylinder fixed to the support top plate 11. Wrap the motor 14 mounted on the upper sieve 13, the air induction pipe 15 connected to the output shaft of the motor 14 in the support cylinder 13, and the air induction pipe 15 It is composed of a fixed tube body 16 fixed to the support top plate 11 and a rotary blade 17 attached to the lower end of the air induction pipe 15.

In addition, an air inlet (13a) is formed in the support cylinder (13) constituting the gas-liquid mixer (12) to allow external air to flow into the air inlet (15a) formed in the upper portion of the air induction pipe (15). In addition, a plurality of air discharge holes 15b are formed in each of the rotary blades 17 at the lower end of the air induction pipe 15.

The lower end of the air induction pipe 15 to which the rotary blade 17 of the gas-liquid mixer 12 is attached is supported by the bearing 18 at the lower end of the fixed tube 16, so that the rotation operation is free. When the air induction pipe 15 and the rotary blade 17 is rotated at a high speed, the air present in the air induction pipe 15 by the centrifugal force appearing as the rotary blade 17 rotates at a high speed The water is discharged into the water through the air discharge hole (15b) to generate a myriad of bubbles in the water, and as the air is discharged to the air discharge hole (15b) as described above, the outside air through the air inlet (13a) Since it is introduced into 15a), bubbles are continuously generated by the air discharged from the air discharge hole 15b.

As described above, bubbles generated in the rotary blades 17 are relatively large and are floated. If the bubbles are large, the floating force is fast and the particles are not effectively distributed evenly in the water. It is impossible to achieve this, and the effect of increasing the amount of polyoxygen cannot be obtained.

The present invention, while holding the portion of the rotary blade 17 of the gas-liquid mixer 12 to produce a relatively large blister without shaking without breaking the bubble generated by the rotary blade 17 very small while bubbles It is characterized by the fact that it can be densely distributed in water.

As a configuration for the above characteristics, the pedestal 19 is installed at the bottom of the wastewater inflow portion 3 of the purification treatment tank 1, and then the bubble generating cylinder 20 fixed to the pedestal 19 is rotated. It was configured to support the fixed tube 16 while receiving the wing 17 therein, the bubble generating cylinder 20 is formed by forming a plurality of bubble grinding holes (21) of long and thin holes up and down.

Meanwhile, the bubble grinding holes 21 formed in the bubble generating cylinder 20 may be formed in a vertical state, a diagonal state, or a horizontal state as illustrated in FIG. 4.

Referring to the operation of purifying the waste water by the present invention configured as described above are as follows.

When operating the motor 4 of the gas-liquid mixer 12, the air induction pipe 15 is rotated at a high speed, according to the centrifugal force action of the rotary blade 17 to rotate between the rotary blades 17 Air is discharged from the meat discharge hole 21 formed between a plurality of, in the state that the rotary blade 17 is not rotating because the bubble generating cylinder 20 inside the water filled state motor 14 In the initial stage of the operation, the rotary blade 17 that rotates at a high speed drives the water flowing into the bubble generating cylinder 20, so that water and the bubbles are discharged together with the bubble grinding hole 21 in the initial stage of purification. As such, as the rotary blade 17 rotates at a high speed, pressure is generated inside the bubble generating cylinder 20 by the air discharged to the air discharge hole 15b, and the bubble generating cylinder 20 is generated by this pressure. The water that flowed in was drained Would stand under the air bubble generating tube 20 inside the air pressure is somewhat compressed state, so the water is no longer being introduced again escape as bubbles grinding balls (21).

When exiting the bubble grinding hole (21) of the elongated hole of the compressed air in the bubble generating container 20 as described above, it is crushed finely and is discharged in all directions while generating very small bubbles. While the air bubbles are weakly floated and slowly floated, the bubble grinder 21 continues to generate small bubbles, so that the entire waste water inlet 3 in which the bubble generating cylinder 20 is installed is very small. Since the air bubbles slowly float in the state where the air bubbles are densely dispersed, foreign matters contained in the water waste water flowing into the wastewater inflow part 3 are densely diffused and floated to the surface by the tiny bubbles that float. The foreign matter injured by the overflow of the upper part of the partition (2) is moved to the water surface of the treated water discharge portion (4) by the conveying action of the collecting plate (9) of the collecting device (10) ) And then collected.

And as described above, the very small bubbles discharged into the water while being broken by the bubble grinding hole 21 is slowly floated, so that the contact time with the water is long, so that the amount of dissolved oxygen can be increased.

According to the present invention as described above, but using the existing gas-liquid mixer, the configuration of holding the rotor blade portion to discharge the air by centrifugal force to the bubble generating cylinder formed with a lot of bubble grinding holes as a rotation action of the rotor blades air pressure in the bubble generating cylinder At the same time, it is a bubble pulverizer with thin and long holes, which makes it possible to diffuse and distribute very small bubbles in the water and increase the floating action of foreign substances in the waste water. In addition, it has the effect of increasing the dissolved oxygen amount by doubling the contact time, and the bubble generating cylinder holds the rotary wing of the gas-liquid mixer while being fixed to the pedestal mounted on the bottom of the purification tank, Even if the air induction pipe is made very long, It has the effect of being able to operate rotationally, and it is possible to reduce the installation area by making the width of the height narrow rather than making the purification tank horizontally wide, so that the waste water purification treatment tank can be installed even in a narrow place. It is a very useful and practical design that provides a beneficial effect in terms of maintenance, as the side effect and the gas-liquid mixer can increase the amount of foreign matter and dissolved oxygen.
