In general, wastewater discharged from a poultry farm such as a poultry farm, a pig farm, a dairy farm, etc., increases the environmental pollution considerably. Therefore, the livestock wastewater is processed through a filtration device or an aeration device.

Conventional apparatuses for treating livestock wastewater can not perform filtration and acidification with a single apparatus or perform filtration and acidification in the same manner, but their functions are limited.

For example, a rotary disk method is a method of submerging a disk in water by about half, rotating it, supplying oxygen, and allowing aerobic organisms to grow on the disk to purify the sewage. However, the rotary disk method has a limitation in the amount of supply of oxygen, which is not suitable for high-concentration and large-scale processing facilities. Further, the waste water treatment through filtration can not be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an embodiment of a power generation apparatus according to the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, Is omitted.

1 is a view for explaining a slurry processing apparatus according to an embodiment of the present invention.

The slurry treatment apparatus according to this embodiment is an apparatus for solid-liquid separation of the slurry 6 and supplying air to the slurry 6, and can perform a solid-liquid separation function or an acid-dissociation function according to the user's selection.

The slurry treatment apparatus has a plurality of reaction vessels (5), and each of the reaction vessels (5) is provided with a vapor-liquid separation apparatus (1000). Thus, it is possible to carry out the air diffusing work for individually supplying the air in each of the reaction tanks 5. In addition, it is also possible to conduct a solid-liquid separation operation in each of the reaction tanks 5 and to carry out the filtration operation successively by passing the filtered slurry 6 through the adjoining next reaction tank 5.

First, in the following, an apparatus 100 for producing a solid-liquid separator will be described in detail.

FIGS. 2 and 3 are views for explaining a heat exchanger 1000 for use in a slurry treatment apparatus according to an embodiment of the present invention.

2 and 3, an acid generator apparatus 1000 according to an embodiment of the present invention includes a rotating body 100, a rotating shaft 200, and a pump 300, Or to perform an acidifying operation.

The rotating body 100 is partially immersed in the liquid, for example, the slurry 6 to be subjected to the solid-liquid separation and the acid work, and rotates. The rotating body 100 is provided with a filtration membrane 102 having a plurality of filtration holes for performing solid-liquid separation, and an inner space 110 may be formed. And may be connected to the inner space 110 when passing through the filtration membrane 102. Accordingly, the filtered liquid in the inner space 110 can be discharged through the drain hole 120 provided in the rotating body 100, have.

1 to 3, the rotating body 100 may be formed in a disk shape, that is, a disk shape as a whole. At this time, the filtration membrane 102 may be provided on both surfaces of the disk-shaped rotating body 100. The filtration membrane 102 may be a membrane membrane having fine through-holes formed therein. The filtration membrane 102 may be installed in the disk-shaped rotating body 100 in a detachable form and may be fixedly coupled to the disk-shaped rotating body 100 as required.

Further, it may further include a pad 150 detachably attached to the side surface of the rotating body 100. Referring to FIG. 1, a strip-shaped pad 150 may be attached to the side surface of the disk-shaped rotating body 100 so as to surround it. The pad 150 can be easily removed from the side of the rotating body 100 so that the slurry 6 can be easily removed when the slurry 6 is excessively attached to the side surface of the rotating body 100.

In this embodiment, the disc-shaped rotating body 100 is arranged so as to stand up and rotate with respect to the liquid to be solid-liquid separated, and is arranged so that when the disc-shaped rotating body 100 rotates, As a result, the portions of the rotating body 100 that are locked with the liquid are repeatedly immersed in the liquid and exposed to the air when rotated.

Referring to FIG. 2, the inner space 110 of the rotating body 100 may be divided into a central space 112 and an outer peripheral space 114 surrounding the central space 112. At this time, the peripheral space 114 may be divided into a plurality of spaces radially divided with reference to the center of the rotating body 100. For example, the central space 112 and the peripheral space 114 are divided by a circular first inner wall 116, and the peripheral space 114 is divided by a second inner wall 116 radially disposed on the first inner wall 116 118) into a plurality of spaces.

3, the central space 112 and the peripheral space 114 may be connected to each other through the air inlet 130. Referring to FIG. The air inlet 130 may have a shape of a through hole formed in the first inner wall 116 or a tube inserted into the first inner wall 116. A plurality of air outlets 130 connecting the central space 112 and the plurality of peripheral spaces 114 may be installed in the first inner wall 116. In this case, At this time, the central space 112 may have a closed structure except for an air passage between the air inlet 130 and the pump 300. That is, the filtration membrane 102 is not installed in the central space 112 but only in the peripheral space 114. Accordingly, when the air is discharged from the pump 300, a suction pressure is generated in the central space 112, and when the air is injected from the pump 300, the discharge pressure may be generated.

The rotating body 100 may further include a drain 120 which is opened at a portion out of the liquid when the rotating body 100 rotates. Referring to FIG. 3, a drain 120 may be formed around the rotating shaft 200, and may have a window-like structure that is opened and closed by sideways. For example, although the door is normally closed due to the force of a spring, when the door of the drain port 120 is opened due to the protrusion when passing through a specific section, the door of the drain port 120 is released from the projection and closed again Lt; / RTI > Accordingly, if a protrusion for opening the door of the drain port 120 is disposed at a portion where the drain port 120 is out of the liquid, the drain port 120 is opened when the liquid is discharged out of the liquid, . Meanwhile, the structure of the drain port 120 is not limited to the above-described structure, and various opening and closing methods known as a structure for opening and closing the drain port 120 can be used. For example, when the drain port 120 comes out of the liquid using a sensor and an actuator, the sensor senses the drain port 120 and actuates an actuator for opening or closing the drain port 120 to open the drain port 120 only for a predetermined period.

In this embodiment, a plurality of drain holes 120 may be disposed in the peripheral portion space 114. Accordingly, when the part of the rotating body 100 is below the surface of the liquid, the drain hole 120 can be closed in the peripheral space 114 located in the liquid-immersed part. Then, when the locked portion of the rotating body 100 is lifted above the surface of the liquid, the drain 120 of the corresponding peripheral space 114 can be operated open. Accordingly, when the rotating body 100 rotates, a plurality of drains 120 are sequentially opened to discharge the filtered liquid.

Referring to FIG. 3, a slope 116a may be formed in the first inner wall 116 to smooth drainage. An inclined surface 116a may be formed on the first inner wall 116 so that the filtered liquid is directed toward the drain hole 120 when the locked portion of the rotating body 100 is lifted above the surface of the liquid. For example, when the drain hole 120 is positioned above the rotary shaft 200, the upper portion of the slope surface 116a may be positioned higher than the drain hole 120 and the lower portion may be directed toward the drain hole 120.

In addition, an air inlet opening / closing member 140 for opening and closing the air inlet 130 may be installed in the rotating body 100. 3, the air inlet opening and closing member 140 is formed in close contact with the inclined surface 116a of the first inner wall 116 in a predetermined section. The air inlet opening and closing member 140 may be formed with a contact surface 142 corresponding to the inclined surface 116a. At this time, the air inlet 130 is formed on the inclined surface 116a of the first inner wall 116, and the contact surface 142 may be disposed on the rotation axis 200. The air inlet opening and closing member 140 is configured to be fixed to the rotary shaft 200 without rotating like the rotary body 100 so that the contact surface 142 can be held at a predetermined position, for example, on the rotary shaft 200. Accordingly, when the locked portion of the rotating body 100 is lifted above the water surface of the liquid, the close contact surface 142 is in close contact with the inclined surface 116a to block the air inlet 130 in the portion above the water surface. The air inlet opening and closing member 140 serves to make the peripheral space 114 below the water surface connected to the central space 112 and the peripheral space 114 above the water surface to be blocked from the central space 112. That is, the air in the central space 112 escapes into the peripheral space 114 above the water surface to prevent the suction and discharge pressures from disappearing. Accordingly, the suction or discharge pressure formed in the central space is transmitted only to the peripheral space 114 below the water surface, and the peripheral space 114 below the water surface discharges air through the filtration membrane 102 or sucks the liquid to perform filtration .

The rotating shaft 200 is a portion for rotatably supporting the rotating body 100. At this time, the rotary shaft 200 may be provided with an air passage through which the air injected and discharged by the pump 300 can pass.

1 to 3, a rotating shaft 200 is connected to a disk-shaped rotating body 100 in a central axis direction. The rotary shaft 200 is formed in a hollow shape so that the inner hollow can be used as an air passage. The air passage of the rotary shaft 200 may be connected to the central space 112.

The pump 300 injects or discharges air into the internal space 110 of the rotating body 100. The pump 300 may be connected to the air passage of the rotating shaft 200 and communicate with the central space 112 of the rotating body 100.

Referring to FIG. 1, in this embodiment, the pump 300 may be directly connected to the rotary shaft 200, but is not limited thereto. Various arrangements and connection structures, which can be connected to the inner space 110 of the rotary body 100, Lt; / RTI >

The above-described solid-liquid separator 1000 for solid-liquid separation can selectively perform the filtration operation and the acidification operation.

When the filtration operation is performed, the pump 300 can discharge air in the internal space 110 to form a suction pressure. Concretely, air can be discharged from the central space 112 to form a suction pressure. As described above, in the present embodiment, the central space 112 is connected to the peripheral space 114 of the liquid-immersed part through the air inlet 130. Accordingly, a suction pressure is generated in the peripheral space 114 in the liquid-immersed part, and the liquid is filtered through the filtration hole of the filtration membrane 102 and sucked into the peripheral space 114. On the other hand, in the portion outside the liquid in the rotating body 100, the drain 120 is opened as described above, and the liquid in the filtered peripheral space 114 is discharged to the outside.

The pump 300 can inject air into the internal space 110 to form the discharge pressure. Specifically, air can be injected into the central space 112 to form the discharge pressure. As described above, in the present embodiment, the central space 112 is connected to the peripheral space 114 of the liquid-immersed part through the air inlet 130. As a result, a discharge pressure is generated in the peripheral space 114 in the liquid-immersed part, and air in the peripheral space 114 is supplied to the liquid through the filtration hole of the filtration membrane 102.

The slurry treatment apparatus of the present embodiment has a plurality of reaction vessels 5 and each of the reaction vessels 5 is provided with the above-described liquid phase apparatus 1000 for both liquid and solid separation, so that the slurry 6 passes through a plurality of reaction vessels 5 The filtration operation can be performed stepwise. The filtered slurry 6 discharged from the drain port 120 of each of the SOFC apparatus 1000 can be transferred to the next reaction tank 5 through a water receiving tube or pipe.

At this time, a smaller filtration hole may be formed in the anaerobic digester 1000 as the latter is installed in the treatment process. That is, the slurry processing apparatus can be configured in such a manner that the coarse particles of the slurry 6 are removed by filtration in the initial process, and the smaller particles are removed by filtration in the following process.

On the other hand, the slurry treatment apparatus may further include a slurry removing unit 400 for removing the slurry 6 attached to the anaerobic digestion apparatus 1000. The slurry removing unit 400 can move toward or away from the rotating body 100 and can scrape off the slurry 6 attached to the rotating body 100 in the vicinity of the rotating body 100. [

1, the slurry removing unit 400 of the present embodiment is formed in a semi-cylindrical shape and is disposed so as to be able to scrape the slurry 6 attached to the filtration membrane 102 of the disk-shaped rotating body 100 . At this time, the semi-cylindrical slurry removing unit 400 may be disposed at an angle of about 10 to 30 degrees with respect to the filtration membrane 102. The slurry 6 to be removed from the rotating body 100 falls into the semicircular shape and a screw 450 for transferring the slurry 6 may be installed inside the slurry removing unit 400.
