Description

Liquid Waste Disposal Equipment {APPARATUS FOR TREATING LIQUID WASTES}

The present invention relates to a liquid waste treatment apparatus, and more particularly, to a liquid waste treatment apparatus for fermenting and purifying organic liquid waste generated from livestock manure, food waste, sewage, etc. .

Liquid wastes (hereinafter referred to as “treatment water”), such as food wastes from domestic households, sewage, and livestock manure from housings, can greatly degrade the quality of streams if they are discharged into rivers without being purified or treated. Therefore, it is regulated by various laws to be purified and discharged.

In order to satisfy these regulations, conventionally, the treated water is collected in a sealed storage space, and then the storage space is kept at an appropriate temperature for a long time so that the microorganisms put into it can be decomposed by microorganisms to proceed. The process of step by step to purify the water to be treated to finally discharge the purified water or make liquid fertilizer.

Since the conventional treatment methods as described above purify the water to be treated step by step, each space for storing the water to be treated is required for each step, and the storage space must be maintained at an appropriate temperature for the microorganism to act for a long time. Therefore, there is a problem in that the cost and processing time required to purify the water to be treated are long.

In order to shorten the treatment time of the water to be treated and to effectively purify the water, a stirring device or the like is installed in the storage space to increase the activity of microorganisms by agitating the water to be treated, thereby shortening the treatment time of the water. Although this method is adopted, this method has a disadvantage in that it takes a lot of processing time.

For this reason, recently, a method of promoting the activity of microorganisms by mainly supplying air to the stored water by using an aeration device is mainly adopted. As an example, Patent No. 10-0363199 (Supplying of oxygen in the complex water using an injector and Stirring device).

1A and 1B, the invention disclosed in the above document includes a nozzle 110 into which the water to be treated flows in, and a suction port through which external air is sucked by a negative pressure generated when the water passes through the nozzle 110. Injector 100 consisting of a first body 120 and a second body 130 formed of a discharge portion having a diameter larger than the diameter of the nozzle 110 and detachably screwed to the first body 120 Wow; Ring-shaped suction effective space portion formed outward between the nozzle 110 and the discharge portion when the first and second bodies 120 and 130 are mutually coupled to minimize friction and vortex resistance of the external air sucked through the suction port ( 140); A pump (200) connected to the injector (100) for discharging the prime mover and the water to be treated as a main body of stirring to supply the injector (100) to the injector (100); It is formed in the inlet of the injector 100 and consists of a suction control valve 300 for adjusting the suction amount of the external air passing through the suction port when the water to be treated passes through the nozzle 110.

According to this configuration, the invention of the document according to the conditions of the water to be treated under the aerobic condition by opening the suction control valve 300 to supply oxygen to the water to be treated and stirred, and in the anaerobic and anoxic conditions intake control valve ( By closing 300), there is an advantage that only stirring is performed in a state in which the oxygen supply to the water to be treated is stopped.

However, the present invention has the following problems.

First, since the pump is installed outside the reservoir and the nozzle is installed in the reservoir, the pipe for supplying the treated water in the reservoir to the pump, and the treated water that has passed through the pump by connecting the pump and the nozzle to each other There is a problem that the installation of the pipe for discharge to the furnace is essential.

Therefore, a complex pipe connected to the inside and outside of the reservoir is installed. Therefore, when a plurality of pumps are installed, the number of pipes increases according to the number, which makes installation more difficult and increases installation time and cost.

In addition, sediment may accumulate in the installed long pipe, and in this case, there is a difficulty in stopping the operation of the storage tank and cleaning the pipe separately.

Second, the technique is provided with a ring-shaped suction effective space 140 in the nozzle, which is configured to be located in a relatively small inner diameter of the nozzle so that the outside air is sucked by the discharge pressure of the water to be treated, Since the suction effective space 140 is formed in a ring shape along the inner diameter of the nozzle, the particles contained in the water to be treated may be clogged by a large foreign matter, thereby causing a problem in that the function may be easily lost.

In addition, since the nozzle has a relatively narrow internal diameter, the nozzle may be easily clogged in the case of the treated water containing the foreign matter having large particles, and thus, the treated water such as food waste, livestock wastewater, etc. There is a problem that is difficult to use as an apparatus.

Third, the above technique has a problem in that the position and direction of the suction pipe of the nozzle and the water to be treated cannot be arbitrarily changed.

However, as another embodiment of the above technology, an example in which the nozzle is installed in the reservoir using the submersible pump is mentioned, but in this case, only the difference in the length of the pipe to be installed is installed in the pipe for connecting the submersible pump and the nozzle to each other. In addition, since a separate supporting structure for preventing the submerged pump and the nozzle from being settled to the bottom of the reservoir by its own weight should be installed, this also has a problem that it is difficult to install a plurality of submersible pumps.

In addition, the technique is a structure in which the submersible pump and the nozzle is installed horizontally to discharge the treated water back into the area where the water is sucked, and this structure accumulates at the bottom of the reservoir in the case of the treated water containing large particles There is a problem in that foreign substances cannot be stirred, and when the submersible pump and the nozzle are installed at the bottom of the reservoir, there is a structural limitation in that the water to be treated in the upper region of the reservoir cannot be stirred.

In order to solve this problem, the pipe may be further installed to provide a height difference between the suction port and the discharge port. However, further installation of the pipe may result in aggravating the above-described problems, and thus may not be practically applied.

Therefore, the present invention has been made to improve the problems of the prior art as described above, the present invention is to clean the treated water containing large particles without installing a complicated pipe for connecting the nozzle portion and the pump. An effective liquid waste treatment apparatus is provided.

Liquid waste treatment apparatus according to the object of the present invention as described above, a plurality of support body is installed in the reservoir; A connecting rod connecting the plurality of support bodies to each other; Consists of a plurality of stirring apparatus installed on the support body; The stirring device includes a nozzle body having a submersible pump therein, a suction pipe provided at the bottom of the nozzle body and installed toward the bottom of the reservoir, and provided at one side of the nozzle body to face the inner wall of the reservoir. It is achieved by including a discharge pipe to be installed and an air supply pipe for supplying external air into the nozzle body.

The present invention uses a submersible pump, and the submersible pump is provided in the nozzle body so that complicated pipes can be eliminated, and even if a plurality of submersible pumps are installed in a storage tank, they are structurally simple and easy to install.

In addition, the treated water containing the large particles accumulated in the bottom of the reservoir is sucked into the nozzle body through a vertically formed suction tube and discharged to the upper side through a horizontal discharge tube, so that the sediment accumulated in the bottom of the reservoir is stirred, thereby improving the overall stirring performance. .

In the process of discharging the water to be treated through the discharge pipe, the outside air is sucked through the air supply pipe provided in the discharge pipe, mixed with the water to be discharged, and the air supply pipe is provided above the discharge pipe, There is no fear that the particles may be blocked by large foreign matter.

On the other hand, the present invention discharges the water to be discharged horizontally through the discharge pipe and hits the inner wall of the reservoir strongly to generate a myriad of vortices, thereby improving the stirring efficiency, thereby improving the stirring time of the treated water stored in the reservoir. It can greatly shorten and purify a larger amount of treated water compared to the same time.

In addition, it is possible to easily change the assembly structure of the support body according to the size and shape of the existing storage tank or anaerobic digester.

The support body 10 is a support structure in which a stirring device 30 to be described later is installed in a storage tank in which liquid waste is stored, which is provided with two vertical tubes 11 having a length vertically as shown in FIG. 2. It is provided, one or more horizontal pipes 12 for horizontally connecting the two vertical pipes 11 is provided, the fixing plate 11 is provided at the lower end of each of the vertical pipes 11 is one support body 10 is configured.

At least two such support bodies 10 are installed in a reservoir, and each support body 10 is installed at an appropriate interval in the reservoir, and a lower end of the support body 10 is a fastening member (for example, a bolt or a nut). The fixed plate 11 is fixed to the bottom of the reservoir in close contact with each other, and the upper ends of the fixing plates 11 are fixed to each other using a connecting table 20 to be described later.

The connecting rod 20 is configured to connect the upper ends of two or more supporting bodies 10 to fix the supporting bodies 10, which are downwardly connected to both ends of the connecting rod 20 having an appropriate length as shown in FIG. 3. Assembly rod 21 having a length is provided, the assembly rod 21 is inserted into the upper end of the support body 10 is assembled. At this time, the length of the connecting table 20 is cut to correspond to this according to the distance between the support body 10 is installed.

The stirring device 30 is installed in the support body 10, and is a device for stirring the water to be treated by sucking and discharging the water to be treated in the storage tank, which is shown in FIG. Similarly, a nozzle body 32 having a submersible pump 31 therein, a suction pipe 33 provided at the bottom of the nozzle body 32 and installed toward the bottom of the reservoir, and one of the nozzle bodies 32. It is composed of a discharge pipe 34 provided on the side and provided along the inner wall of the reservoir and an air supply pipe 35 for supplying outside air into the nozzle body 32.

The stirring device 30 is formed in the nozzle body 31, the suction pipe 33 and the discharge pipe 34 are integrally molded, the submersible pump 31 is installed inside the support body 10, respectively. However, due to such a structure, the stirring device 30 of the present invention can delete a complicated pipe installed in the existing, and can be easily installed even if a plurality of stirring devices 30 are installed in the storage tank 1.

In addition, the stirring device 30 of the present invention is installed at a predetermined angle (A) so that the discharge pipe 34 toward the inner wall of the reservoir 1 when installed in the support body 10 as shown in FIG. In this way, the water to be sucked into the stirring device 30 collides with the inner wall of the storage tank 1 through the discharge pipe 34 to generate vortex, and the other stirring device 30 also has an inner wall of the storage tank 1. By discharging the water to be processed to generate a vortex, a myriad of vortices are generated in the water to be stored in the storage tank 1, and stirring is performed smoothly.

At this time, in the present invention, the process water is introduced into the stirring device 30 and the outside air is sucked and mixed in the process of quickly discharged into the discharge pipe 34, and the process water mixed with the air thus forms the inner wall of the storage tank 1. Towards the discharge, a myriad of vortices are generated, thereby improving the stirring performance of the water to be treated.

Furthermore, as shown in FIG. 6, the suction pipe 33 is disposed on the bottom surface of the nozzle body 31 to form an angle A ′ substantially perpendicular to the discharge pipe 34, whereby the suction pipe 33 is discharged. Compared to the position of the pipe 34, the treated water accumulated in the bottom of the storage tank 1 is sucked, and the treated water thus sucked is discharged to the upper portion of the storage tank 1 through the discharge pipe 34 and stored in the storage tank ( Agitation is performed between the upper and lower parts of 1).

In the case of the water to be treated containing such large particles by this action, the problem of the prior art in which the precipitate is accumulated at the bottom of the reservoir and the stirring effect is not evenly transmitted to the whole in the reservoir 1 is improved, and furthermore, in the reservoir 1 By forcibly sucking and stirring the water to be treated at the bottom, sediment is prevented from being deposited at the bottom of the reservoir 1.

Hereinafter will be described in more detail through an embodiment of the present invention.

≪ Example 1 >

2 and 5 are provided in the reservoir (1) to face each other, as shown in Figure 2 and 5, by connecting the upper end of the support body 10 on both sides by using two connecting rod (20) By fixing, the side shape is installed so that the lower side is an open "c" shape.

When the water to be treated in the storage tank 1 is driven by the stirring device 30 installed as described above with reference to FIGS. 4 and 6, a strong earth output is generated toward the discharge pipe 34. As a result, the water to be treated at the bottom of the reservoir 1 is sucked into the nozzle body 32 through the suction pipe 33, and the water to be sucked into the nozzle body 32 is quickly discharged through the discharge pipe 34. . At this time, the water to be discharged is discharged toward the inner wall of the storage tank 1 to hit the inner wall of the storage tank 1 to generate a myriad of vortices.

In addition, external air is introduced into the air supply pipe 35 by the water to be quickly passed through the discharge pipe 34, and the air thus introduced is mixed with the water to be treated and discharged together toward the inner wall of the storage tank 1.

Therefore, in the present invention, the agitation effect is relatively improved compared to repeating agitation only by suctioning only the target water of the surroundings in which the agitator 30 is installed, and the target water including large particles precipitated at the bottom of the reservoir 1. The suction prevents sediment from settling in the bottom of the reservoir 1.

When the four support bodies 10 are fixed in this way, four stirring devices 30 are installed toward the inner wall of the reservoir 1 in each of the support bodies 10 as shown in FIG. .

In the present invention installed as described above, the number of installation of the support body 10 increases or decreases according to the number of installation of the stirring device 30, and the number of installations of the connecting table 20 used according to the number of installation of the support body 10 increases or decreases. If the number of installation of the stirring device 30 is increased, the stirring force of the water to be stored in the storage tank 1 is improved.

Therefore, the number of installation units of the stirring device 30 is determined according to the size of the storage tank 1 and the treatment capacity of the water to be treated, and the support body 10 and the connecting table 20 are adapted to the number of installation units of the stirring device 30. By determining the number of units installed, the structure in which they are assembled can be varied.

That is, by determining the number of the support body 10 and the connecting table 20 according to the number of stirring device 30 can be implemented in various forms such as polygons.

On the other hand, the present invention by discharging the water to be treated horizontally toward the inner wall of the reservoir 1 to generate a high-speed vortex that rotates in one direction to agitate the water to be treated, whereby the corner portion inside the reservoir (1) There is a possibility that an area which is not affected by the vortex of the water to be treated may be generated, and when the reservoir is formed in a cylindrical shape, a side wall to which the water can be strongly impacted is required. Thus, as shown in FIGS. Likewise, the auxiliary side plate 40 may be further installed in the reservoir 1 as necessary.

The auxiliary side plate 40 has flanges 41 formed at both ends thereof, and is directly installed and fixed to the inner wall of the reservoir 1 using a wolf and a nut. The auxiliary side plate 40 is formed inside the rectangular reservoir 1. The stirring efficiency of the water to be treated is increased by minimizing the area which is not affected by the vortex, or by using it as a side wall for forming a cylindrical reservoir cold irregular vortex.

On the other hand, the submersible pump 31 of the present invention can be carried out by further comprising a timer, if the user sets the operating cycle of the submersible pump 31 using this timer, stirring by the set operating time and stop time without additional operation The motor 31 is automatically controlled.

For this purpose, the present invention is implemented as a filter made of cedar, and the wire 54 is the bottom of the reservoir 1. The upper end is preferably connected through the pulley so that it can be installed in the main body and easily towed when necessary.

In addition, in the case of the housing 51 is installed inside the reservoir 1, in view of this is carried out to have a length from side to side in the reservoir (1).

The microbial propagation box 50 is carried out at a lower height than the stirring device 30 of the present invention, and the microbial propagation box 50 is minute due to the influence of the vortices of the liquid waste by the operation of the agitation device 30. The solids pass through the filter 52 of the microorganism propagation box 50, and in this process, the fine solids are adsorbed and removed by the filter 52.

At this time, the adsorbed fine solids are collected in the microorganism propagation unit 53 located at the bottom thereof. The collected fine solids stably propagate the microorganisms, and the influence of the vortices generated by the microorganisms in the storage tank 1. It serves to prevent receiving.

As a result, the microorganism propagation box 50 has an effect of shortening the growth time of the microorganisms introduced into the storage tank 1.

Furthermore, since the microorganisms already propagated in the microbial propagation box 50 remain, it is more effective to replace the liquid waste stored in the storage tank 1 with the use of the microorganisms when breeding the microorganisms in another storage tank 1. It can grow microorganisms quickly and quickly.
