{Septic apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condensation treatment apparatus for treating industrial sewage such as condensate. More specifically, the present invention performs aeration and microbial fermentation in the first treatment tank and the second treatment tank using an existing simple purification tank including three stage treatment tanks, stabilized in the third treatment tank, and then filtered. And completely remove the treated water by forced evaporation, and circulate the non-evaporated treated water to one or two or more of the treatment tanks, and then operate in accordance with the changing sewage throughput. It relates to a condensation processing device.

Industrial sewage, such as livestock sewage from livestock farms such as cattle, pigs, and poultry farms, contains large amounts of organic pollutants that cannot be released as livestock manure.

In order to treat industrial wastewater such as livestock wastewater containing such a large amount of organic pollutants, simple purification tanks have been developed and installed.

These conventional simple purification tanks treat organic pollutants such as shaft powder by aeration and microbial treatment to be discharged into treated water, and usually include aeration tanks and stabilization tanks. It is configured to discharge water. However, the treated water effluent from conventional simple septic tanks that treat livestock sewage by aeration and microbial treatment is still present in biological oxygen demand (BOD), chemical oxygen demand (COD) and turbidity, although a significant portion of organic contaminants have been removed. In many cases, it was impossible to discharge the water as it was.

Therefore, the treated water which has been treated by conventional septic tanks, but cannot be discharged, has been collected in a constant reservoir and treated by natural evaporation. In addition, some of the treated waters have been used as cleaning water for cleaning the barn or the like, or have been liquefied to be scattered and treated on farmland. However, the spread to the arable land due to such natural evaporation and liquefaction is also limited, and since the use of the cleaning water still needs to be treated by a septic tank, the conventional septic tank has a limited throughput of sewage of 50 to 80%. .

An object of the present invention is to perform the aeration and microbial fermentation in the first and second treatment tanks using the existing simple purification tank including three stage treatment tanks, stabilized in the third treatment tank, and then filtered and forced. Completely remove the treated water by evaporation, and further process the non-evaporated treated water and circulate it back to any one or two or more of the treatment tanks, which can be operated according to the changing sewage throughput. To provide a device.

The condensation processing apparatus according to the present invention includes at least two treatment tanks for aeration and microbial treatment and at least one treatment tank for stabilization, and includes a filtration tank for filtering the sewage treated through the treatment tanks and the filtration tank. An evaporator forcing evaporation of sewage through forced spraying and a defoamer containing residual sewage not evaporated in the evaporator, removing bubbles from the sewage, and returning it to any one of the above treatment tanks Fluid flows are connected to each other.

The raw water tank is connected to the first processing tank among the treatment tanks, and a first screen is installed before the raw water tank.

The second screen is installed in the treatment tank for stabilization of the treatment tank.

A preliminary filter is further installed between the treatment tank and the filtration tank.

Treatment tanks that perform aeration treatment among the treatment tanks are connected to one blower to be aerated.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

As shown in FIG. 1, the condensation treatment apparatus according to the present invention includes at least two treatment tanks for aeration and microbial treatment and at least one treatment tank for stabilization, and receives sewage treated through the treatment tanks. Evaporator 17 and evaporator 17 for evaporating the filtration tank 16 for filtration and the sewage passing through the filtration tank 16 by forced blowing spray are received, and the bubbles are removed from the sewage. In addition, the defoaming machine 18 which is returned to any one of the treatment tanks is characterized in that the fluid flow is connected to each other.

The treatment tanks are divided into treatment tanks for aeration and microbial treatment and treatment tanks for stabilization, and are tanks for storing and treating a certain amount of sewage. Treatment tanks for aeration and microbial treatment are indicated by a first treatment tank 13 and a second treatment tank 14 in FIG. 1. The aeration nozzles 33 are provided in the lower part of these 1st processing tank 13 and the 2nd processing tank 14, These aeration nozzles 33 are connected to the blower 31 via the blower pipe 32. . Pressurized air supplied by the operation of the blower 31 is discharged into the sewage in the treatment tank to decompose and treat organic contaminants by oxygen or the like by oxidation or the like, and also microorganisms and / or present in the treatment tank. The microorganisms supplied from outside, especially aerobic microorganisms, decompose and treat organic contaminants in the sewage in the treatment tank more quickly. All of the microorganisms used in these microbial treatments, especially aerobic microorganisms, are those derived from nature or those which have been expanded in culture. The raw water tank 12 is installed before the first treatment tank 13, and the first screen 11 is installed before the raw water tank 12, and flows in from the sewer through the first conduit 21. The foreign matter contained in the sewage is first filtered by the first screen 11, so that only water and organic contaminants are transferred from the raw water tank 12 to the first treatment tank 13 via the primary inlet 22. Allow inflow. The primary screen has a network structure like a conventional wire mesh. The raw water tank 12 temporarily stores the sewage of the treatment target introduced through the primary screen, and serves to smoothly flow the sewage into the first treatment tank 13. In addition, the treatment tank for stabilization is represented by a third treatment tank 15, the sewage introduced from the first treatment tank 13 and the second treatment tank 14 for the aeration and microbial treatment for a predetermined time. It stably stores water to secure time for complete treatment by microorganisms, and also serves to store sewage for a certain time for sedimentation of sediment and release of gas. The first treatment tank 13 and the second treatment tank 14 are connected to the secondary inlet 23, and similarly, the second treatment tank 14 and the third treatment tank 15 are the tertiary inlet 24. Can be connected to.

The sewage treated via the treatment tanks is introduced into the filtration tank 16 via the second conduit 25. This filtration tank 16 serves to filter out all solids contained in the sewage treated by the treatment tanks. Multiple filter layers may be formed in the filtration tank 16. These filter layers may preferably consist of a first filtration layer made of gravel, a second filtration layer made of activated carbon and a third filtration layer made of sand. The first filtration layer made of gravel primarily filters large solids, and the second filtration layer made of activated carbon plays a role of adsorption and sterilization of particulate solids and removal of odor due to the characteristics of activated carbon. The third filtration layer made of sand supports the activated carbons constituting the second filtration layer, filters the relatively small solids passing through the second filtration layer, and serves to allow the filtered treated water to easily escape. However, it will be understood by those skilled in the art that the use of other filtration layers other than those mentioned above is also possible, and the present invention is not limited to the materials constituting the filtration layers in these filtration tanks 16. . In addition, a pump 26 may be installed in the second conduit 25 to smoothly supply the treated water from the third treatment tank 15 to the filtration tank 16. The pump 26 may be understood that a conventional water pump 26 may be used, and is well known to those skilled in the art to purchase and use commercially available.

Some or all of the sewage that has passed through the filtration tank 16 is fed to the evaporator 17 via a third conduit 27 where it is forcibly evaporated and treated. The evaporator 17 forcibly sprays the treated water into the air by forcibly pressurizing the air through a microtubule such as a fine nozzle or the rotation of a powerful fan in order to make the removal of the treated water faster than the evaporation of natural moisture. Higher evaporation rates are used. It can be understood that such an evaporator 17 is also known enough to be purchased and used commercially available. A part or all of the sewage that has passed through the filtration tank 16 is returned to the first treatment tank 13 or the second treatment tank 14 via the sixth conduit 30 to be treated with the first treatment tank 13 or the first treatment tank. It is used to lower the pollution concentration of the sewage to be treated in the two treatment tanks 14. In addition, it may be supplied to the third processing tank 15 as necessary. The third conduit 27 may be provided with a pump 26 to smoothly supply the treated water from the filtration tank 16 to the evaporator 17.

In addition, the remaining treated water not evaporated in the evaporator 17 is supplied to the defoaming machine 18 via the fourth conduit 28. The defoaming machine 18 stores the treated water for a predetermined time, and naturally discharges the air or the like contained in the treated water by evaporation or the like by standing in the reservoir, and removes the generated bubbles. The defoaming and naturally degassed treated water in the defoaming machine 18 is mainly returned to the second treatment tank 14 via the fifth conduit 29 and used to lower the pollution concentration of the sewage to be treated. Moreover, it can also be supplied to the 1st process tank 13 and the 3rd process tank 15 as needed.

The second screen 42 is installed in the treatment tank for stabilization of the treatment tank, by the second screen 42 after the second filtration tank 16 or the second conduit 25 connected to them. As much as possible, do not allow impurities to be introduced, and only treated water is introduced.

A preliminary filter 41 may be further installed between the treatment tank and the filtration tanks 16 to facilitate maintenance and repair of the filtration tank 16. As the pre-filter 41 may include a conventional filter net.

Among the treatment tanks, a plurality of treatment tanks such as the first treatment tank 13 and the second treatment tank 14 which perform aeration treatment are connected to one blower 31 and aerated.

Compared with the conventional simple septic tank according to the present invention by the configuration as described above has the following advantages.

First, in the final treatment efficiency of the treated water, since the existing simple purification tank is made by natural evaporation by circulation in the barn, the treatment capacity should be small and retained a large amount of treated water that cannot be discharged for a long time. In the case of the condensation treatment device according to the present invention, the evaporator 17 is forced to evaporate, so that the treatment capacity is large, and the non-discharged treated water can also be used to lower the pollution concentration of the sewage to be treated again. Problems such as securing of the current destination can be eliminated as a cause.

Secondly, in the aeration, the conventional simple purification tank is configured to aeration the one treatment tank with one blower 31, whereas in the case of the condensation processing apparatus according to the present invention, two or more treatment tanks are used for one blower 31. The aeration process is configured to enable aeration treatment, and the first treatment tank 13 performs preliminary aeration, and the second treatment tank 14 performs aeration in earnest to increase the efficiency of organic matter removal and odor removal. Can be. In addition, due to the double aeration can be treated more stably compared to the conventional simple purification tank even inflow of a large amount of sewage.

Third, in the turbidity improvement, the conventional simple purification tank improves turbidity by passing the screen and removing scum in the fermentation tank when the raw water itself is introduced. In addition to passing the screen by 11) and removing scum in the fermentation tank, filtration by the second screen 42 in the third treatment tank 15 and by the filtration tank 16 (passing into the pre-filter 41 as necessary). Filtration can greatly reduce turbidity by completely removing suspended solids that cause turbidity.

Fourth, in the concentration dilution at the time of inflow of raw water, in the case of the conventional simple septic tank, the raw water is temporarily processed in the order of inflow, aeration, stabilization, and circulation, and there is no means or a device for diluting the raw water. When introduced into, there was a problem that the microbial fermentation is not or delayed by the high concentration of raw water, but in the case of the condensation treatment apparatus according to the present invention is processed in the order of raw water-preliminary aeration-main aeration-stabilization-filtration-evaporation, And since some of the treated water is returned to the treatment tank in the step of evaporation to dilute the concentration of raw water in the treatment tank, it is possible to smoothly treat the sewage so that a constant microbial fermentation always occurs.

Fifth, there is an advantage that the installation cost of the dust treatment apparatus according to the present invention is much cheaper than the conventional simple purification tank also in the installation cost. As of the filing date, the conventional simple septic tank takes about 45 to 65 million won per 1000 pigs, including civil engineering, and, according to the present invention, takes up to 17 million to 20 million won.

Therefore, according to the present invention, the amount of sewage that changes from time to time is completely removed by completely removing the treated water properly treated by forced evaporation and further circulating the treated water that has not been evaporated to any one or two or more of the treatment tanks. There is an effect of providing a shaft processing apparatus that can be operated in accordance with.
