Description

BACKGROUND OF THE INVENTION Field of the Invention [0001]

The present invention relates to a housing wastewater purification facility, and more particularly to a housing wastewater purification facility that removes solid matter from wastewater generated in a housing and performs a stepwise process of oxidative decomposition and sterilization, thereby efficiently cleaning wastewater Facilities.

As the livestock farms become large and complex, many livestock are densely cultivated inside the standardized housing, resulting in the generation of waste water such as a large amount of stool.

Such wastewater is usually mixed with feces and urine of the livestock, and also contains a large amount of organic matter, thereby generating odor due to decomposition of the organic matter.

Thus, wastewater having a high concentration of solids such as feces can not be purified by a microorganism treatment method which is a general wastewater purification method because microorganisms can not live in wastewater.

For example, wastewater from pig farms in livestock wastewater is mixed and discharged together with feces and urine. BOD of wastewater is 15,000 ~ 20,000 ppm.

Since the wastewater contains a large amount of solid matter, there is almost no oxygen in the wastewater. Therefore, it is difficult to purify the microorganisms because the microorganisms can not live in the wastewater. Even if the wastewater is purified, it takes a long time to purify the solid matter.

Therefore, it is preferable to separate the solid material and then purify the separated wastewater by a contact oxidation method using general microorganisms.

However, it is difficult to separate the solids from the urine when the water content is high and the amount of water is high as in the case of dairy cattle or pig manure. There is a difficulty, and therefore a considerable expense.

A related art is described in Korean Patent No. 10-0665664 ("Conservation Wastewater Treatment Facility").

This prior art is related to a purification facility having a high removal efficiency of suspended solids using microbubbles and a high purification rate using oxygen and ozone.

However, in the prior art, as the inflow amount of the wastewater increases, the speed of the wastewater increases, and accordingly the untreated wastewater is discharged, resulting in a drastically lowered purification efficiency.

As shown in FIG. 1, the solids removal device 130 may be a structure in which a motor, a rotating roller, a belt connecting the motor and the rotating roller, and a wing for removing solid matter are provided on the belt.

On the other hand, it is more preferable that a collection tube or a collecting tank for collecting wastewater generated in the housing is separately provided, and the wastewater is supplied to the solid-liquid separation vessel 100.

The sedimentation tank 200 is connected to a return pipe (not shown) through which wastewater discharged from the solid-liquid separation tank 100 is introduced and the lower sediment is conveyed to the solid-liquid separation tank 100 by an air supply pipe 211 connected to the blower 900 210).

As shown in FIGS. 1 and 2, the sedimentation tank 200 has an inclined lower wall surface, a center pipe 220 having an inner hollow at its center, and the other side of the wastewater discharge pipe 120 is connected to a center pipe 220 so that the wastewater discharged from the solid-liquid separation tank 100 flows into the central pipe 220 of the sedimentation tank 200 through the wastewater discharge pipe 120.

That is, the wastewater from the solid-liquid separating tank 100 flows into the settling tank 200 through the wastewater discharge pipe 120 and the central pipe 220 so that the wastewater is collected from the center side by artificially. The transfer pipe 210 is installed in the central pipe 220 of the settling tank 200 so that the solid material settled on the bottom of the settling tank 200 is transferred to the solid- The transport pipe 210 is installed in the center pipe 220 to the bottom of the settling tank 200 and the upper part of the transport pipe 210 is connected to the upper part of the solid- An air supply pipe 910 connected to the blower 900 is connected to a lower portion of the return pipe 210 so that the air supplied from the blower 900 is supplied to the lower portion of the return pipe 210 through the air supply pipe 211 At the same time, the sediment under the sedimentation tank 200 is conveyed to the solid-liquid separation tank 100 via the return pipe 210 together with the sediment.

This principle is based on the principle of air pump that when air is blown from the bottom of a tube containing liquid, air enters into the tube and the air rises up. At the same time, the air and liquid in the tube are mixed with air The pressure is lower than the lower liquid, so that the liquid which does not contain air pushes up the liquid in the portion where the remaining air is mixed because the pressure is low. The sedimentation tank 200 having the above-described structure is intended to completely remove sediment that has not been separated from the solid-liquid separation tank 100. The central pipe 220 in the settling tank 200 is provided for this purpose. When the wastewater discharged from the solid-liquid separation tank 100 flows into the central pipe 220, the bottom pipe 220 moves downward, .

One side of the first transfer pipe 230 is connected to the upper side of the settling tank 200. The first conveyance pipe (230) is a passage through which the wastewater after the precipitation process is discharged in the next process. As shown in FIG. 1, a filter may be installed on one side of the first conveyance pipe 230 to prevent the suspended solids from entering the next treatment tank.

The aeration tank 300 is configured such that the other side of the first transfer pipe 230 is positioned below the aeration tank 300 so that wastewater discharged from the settling tank 200 flows into the lower portion through the first transfer pipe 230 . The wastewater discharged from the settling tank 200 flows into the upper part of the aeration tank 300. If the inflow amount of the wastewater increases, the wastewater flows at a higher speed, There is a problem that the wastewater flows into the next treatment tank without sufficient aeration treatment in the aeration tank 300. According to the present invention, the first transfer pipe 230 is further provided, and the wastewater discharged from the settling tank 200 flows into the lower portion of the aeration tank 300, thereby preventing wastewater that has not been sufficiently treated from flowing into the next treatment tank can do.

A plurality of communication members 320 are filled in the aeration tank 300 and a second micro bubble generator 310 connected to the blower 900 is installed in the lower portion. At this time, it is preferable that the second micro-bubble generating device 310 is the same device as the first micro-bubble generating device 110.

The method of installing the communication member 320 in the aeration tank 300 can be variously modified by those skilled in the art. For example, as shown in FIGS. 1 and 2, the frame 330 may be filled with the communication member 320 after the frame 330 of the wire net, the stainless net, and the PVC net is formed, The frame 330 may be filled with the communication member 320 after preparing the frame 330 in the form of a rectangular box having a porous lower part.

At this time, it is preferable that the lower part of the frame 330 is separated from the bottom of the aeration tank 300 and the upper part is installed below the water surface.

The communicator 320 is a small-sized tubular body having an inner hollow shape, and can be used as a waste bottle or a waste container, and a plastic Yakult bottle is most preferable. At this time, when it is desired to increase the activity of the microorganism, it is preferable to drill a hole in the bottom of the Yakult bottle to increase the supply of the microbubbles.

In this structure, bubbles having a diameter of 1 to 50 mu m are generated in the second micro-bubble generator 310 installed at the lower part of the aeration tank 300, and the bubbles rise through the communication body 320, Oxygen is supplied to the microorganisms.

The aeration tank 300 formed in this form is adapted to purify contaminants in the wastewater by microorganisms by contact oxidation and aeration of the wastewater into which the solid matter has been separated from the settling tank 200. The oxygen is supplied by the minute bubbles generated in the second micro-bubble generator 310 installed at the lower part of the aeration tank 300, and the microorganisms purify the wastewater using the oxygen.

Also, it is preferable that the vortex generating device 800, which is the same as that provided in the solid-liquid separating tank 100, is also provided on the lower floor of the aeration tank 300. As described above, the vortex generator 800 uniformly spreads the minute bubbles generated in the second micro-bubble generator 310 in the wastewater, thereby improving the purification efficiency.

When the communication member 320 having the hole formed at the bottom thereof stands uprightly, the minute bubbles pass through the inside of the frame 330 so much that a large amount of oxygen is supplied, Because microorganisms are actively inhabited, these microorganisms oxidize contaminants and purify the wastewater.

In addition, air, that is, oxygen is hardly supplied to the communicating body 320 lying on the side, so that the anaerobic microorganisms are inhabited in the communicating body 320, and the contaminants in the wastewater are purified by the mold fermentation.

The communicator 320 is angled at an angle of 45 °, which means that the aerobic and anaerobic intermediate microorganisms are inhabited and used to purify the wastewater.

These various kinds of microorganisms can be naturally generated or can be inhabited through a method of installing the communicator 320 in advance after putting it in the communicator 320.

Although not shown in the drawing, a plurality of aeration tanks 300 may be provided. This is because, when the scale of housing is large, the inflow and outflow speed of the wastewater supplied to the aeration tank 300 is accelerated. In this case, sufficient aeration does not proceed and the wastewater is hardly purified.

The second transfer pipe 340 is configured to allow the wastewater discharged from the aeration tank 300 to flow into the lower portion of the ozone input vessel 400 in the same manner as the first transfer pipe 230, It is possible to solve the problem of being discharged to the next treatment tank without being sufficiently treated.

A third micro-bubble generator 410 connected to the ozone generator 420 is installed below the ozone input vessel 400 to supply air containing ozone supplied from the ozone generator 420 to the third micro- (410) to be supplied to the waste water in the ozone input vessel (400).

Examples of the fine bubbles to be supplied into the ozone supply vessel 400 through the ozone generator 420 and the third micro bubble generator 410 include 5 to 15% by volume of ozone and 85 to 95% by volume of oxygen. By supplying the minute bubbles containing ozone into the ozone input vessel 400, it is possible to decompose the substances such as 'bilirubin' and various environmental hormones in the manure of the livestock to obtain the effluent purification effect.

On the other hand, it is preferable that vortex generators 800, which are the same as those provided in the solid-liquid separating tank 100 and the aeration tank 300, are provided on the lower floor of the ozone input vessel 400. The vortex generator 800 spreads the fine bubbles generated in the third micro bubble generator 410 uniformly in the wastewater to improve the purification efficiency.

In addition, one side of the third conveyance pipe 430 through which the wastewater having oxidized and decomposed bilirubin and environmental hormones is discharged is connected to the upper side of the ozone input vessel 400.

The other side of the third conveyance pipe 430 is connected to the ultraviolet ray generator 500 through the third conveyance pipe 430 so that the wastewater oxidized and decomposed in the ozone input vessel 400 is introduced into the ultraviolet ray generator 500 As shown in FIG.

In addition, the ultraviolet ray tank 500 is provided with an ultraviolet lamp 510 to decompose the ozone remaining in the wastewater while sterilizing the wastewater that has been oxidatively decomposed by bilirubin and environmental hormones. At this time, the wavelength of the ultraviolet lamp 510 may be 253 to 255 nm so as to decompose ozone and residual contaminants, and most preferably, a quartz ultraviolet lamp 510 that emits ultraviolet light having a wavelength of 253.7 nm, .

Further, when the wavelengths for decomposing ozone and the wavelengths for decomposing contaminants are different, a plurality of ultraviolet lamps 510 having different wavelengths may be provided.

Further, a purified water discharge port 520 through which the purified water is discharged is formed on the upper side.
