Field of the Invention The present invention relates to an apparatus for separating fine solids suspended by adhering a gas in a liquid medium, and more particularly, for example, in a wastewater treatment reactor. When adsorbing and decomposing impurities and harmful substances in wastewater by contacting the wastewater with ion exchange resin, activated carbon, other carriers or microbial flocs, these are adsorbed or adhered to the gas generated by the reaction etc. The present invention relates to an apparatus for separating fine solids that adhere and float in a liquid medium used to prevent the solids from floating, floating, and flowing out of the reactor. [0002] For example, as a method for treating organic wastewater, there is an upflow anaerobic sludge blanket method using anaerobic microorganisms that have been granulated and self-granulated. The wastewater is biodegraded by contacting the organic matter with the granulated anaerobic microorganisms, and the gas generated at that time adheres to the granulated anaerobic microorganisms and floats up. There is known a solid-gas-liquid separation apparatus of a continuous treatment system for further decomposing and purifying wastewater. Heretofore, for this type of solid-gas-liquid separator, forcible separation of solids using an expensive filter or the like has been used. Among them, as a solid-gas-liquid separation mechanism of an anaerobic microorganism treatment apparatus for wastewater, as shown in FIGS. 1 to 4, it has various shapes from a relatively simple separation structure to a complicated one. I have. As indicated by arrows, the flow of wastewater flows upward, and anaerobic microorganisms and wastewater in the device come into contact with each other, decompose organic matter, and the cells generated by the generated gas, Bacteria, treated water and gas are to be separated and recovered by a solid-gas-liquid separation mechanism at the top of the apparatus. That is, in the example of FIG. 1, the wastewater flowing from the lower part comes into contact with the anaerobic microorganisms at the lower part of the apparatus, decomposes organic matter, and the cells and the gas float by the gas generated in the process. However, the gas is collected at the central part A of the apparatus by the solid-gas-liquid separation mechanism at the upper part, and is collected by B, while the bacterial cells descend. In addition, the treated water becomes supernatant water in part C and becomes
Spilled out of the system. In the example of FIG. 2, the wastewater flowing from the lower part comes into contact with the anaerobic microorganisms at the lower part of the apparatus, decomposes organic matter, and the gas generated in the process causes the cells and the gas to float, while the upper part solidifies. The gas is collected by the gas-liquid separation mechanism around the device E and collected by F, while the cells descend. Further, the treated water becomes supernatant water in the G portion and flows out of the system from the outer periphery H. In the example of FIG. 3, the scale of the example of FIG. 1 is increased. That is, the same treatment as that of FIG. 1 is performed, and the floated bacterial cells and gas are collected by the solid-gas-liquid separation mechanism at the upper portion, and the gas is collected in the I section of the apparatus, collected by J, while the bacterial cells descend. Further, the treated water becomes supernatant water in the K portion and flows out of the system from the outer periphery L. In the example of FIG. 4, the scale of the example of FIG. 2 is increased. That is, the same processing as in FIG. 2 is performed, and the floated bacterial cells and gas are collected by the solid-gas-liquid separation mechanism at the upper portion of the apparatus at the M portion of the apparatus and are collected by N, while the bacterial cells descend. In addition, the treated water becomes supernatant water in the O portion and flows out of the system from the outer periphery P. [0005] However, in a conventional solid separation apparatus having a solid-gas-liquid separation mechanism, a relatively simple separation structure does not provide sufficient amounts of bacteria, treated water and gas. Separation cannot be performed, and bacteria are often mixed with the treated water and the bacteria flow out.Therefore, there is a problem that the amount of wastewater is limited to a certain amount, and thus the treatment amount is limited and the capacity of the apparatus is increased. Was. In addition, in the case of a structure having a complicated separation structure, there is a problem that it takes time to manufacture and the initial cost is high. Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, to provide an apparatus which has a sufficient solid-gas-liquid separation capability, has a simple structure and can keep initial costs low. Is to do. According to the present invention, fine liquids having a specific gravity higher than the specific gravity of the liquid medium in the liquid medium, and floating and floating in the liquid medium while adhering gas. In a separation device that separates and removes solids from a gas, the separating device is tilted upward from the center of the device liquid medium by using the floating force of the gas
The solid-gas-liquid separation plate provided at an angle and the lower surface
The to cause a turbulence in the liquid medium of the protrusions, the fine solids,
Provided is an apparatus for separating fine solids in a liquid medium, which has a solid-gas-liquid separation mechanism therein for separating and recovering a liquid medium and a gas, respectively. The solid-gas-liquid separating apparatus according to the present invention is characterized by a mounting angle and a position of the solid-gas-liquid separating plate 1, a turbulence assisting projection 2 below the mounting of the solid-gas-liquid separating plate 1, and other solid-liquid separating plates. A gas-liquid separation plate 3, a triangular gas trapping auxiliary plate 4, and a gas circulation pipe 5 used when the amount of gas is small and turbulence hardly occurs. Here, the solid-liquid separating plate 1 (for example, a plate made of stainless steel) is inclined upward (preferably at an angle of 45 to 55 °) from the center of the liquid medium in the solid-liquid separating device. And a gas-collecting auxiliary plate 4 provided on a wall near an intermediate portion in the height direction of the apparatus and a liquid medium free surface. Solid-gas-liquid separation plate 1
A plurality of turbulence assisting projections 2 (for example, having a length of 50
A protrusion having a height of about 150 mm) is provided, and the solid having gas rising from below collides with the solid to generate a downward flow as shown by the arrow in FIG. 5 so that the solid is collected downward. The second solid-gas-liquid separation plate 3 extends, for example, a part of the gas holder 10 into the liquid medium, extends to a depth sufficiently deeper than the upper gap 6 of the first solid-gas-liquid separation plate 3, and flows out of the gap 6. The solids now collide and separate from the gas so that the solids are returned down through the gap 7. In the solid-gas-liquid separation device according to the present invention, wastewater introduced by a pump or the like from the lower portion of the device is efficiently contacted with anaerobic microorganisms in the device, and at the same time, gas generated by biodegradation of organic matter. Microbial cells rise together with the treated water and gas, and the cells, treated water and gas are separated by the upper solid-gas-liquid separation plates 1 and 3, and only treated water flows out of the system, and the gas is transferred to the upper gas holder 10. Since the cells are collected and circulated to the lower part of the device along a turbulent flow descending in the device, anaerobic treatment of the desired wastewater can be efficiently performed. FIG. 2 is a view showing an example of an apparatus for separating fine solids having a solid-gas-liquid separation mechanism according to the present invention and having a solid-gas-liquid separation mechanism in which a gas adheres and floats in a liquid medium. A preferred embodiment of the present invention will be described below using the apparatus shown in FIG. 2, but it is needless to say that the scope of the present invention is not limited to this embodiment. That is, the solid-gas-liquid separating plate 1 is set at an angle of 50 ° (normally 45 to 55 °) with respect to the horizontal plane, and the upper portion thereof is about 100 mm below the surface of the water (normally 50 to 150 mm). The lower part is provided with a space 7 with the triangular gas collecting auxiliary plate 4.
Is set to about 200 mm (usually 150 to 250 mm), and several turbulence assisting projections 2 are provided below the solid-gas-liquid separation plate 1 to create a flow of water in the direction of the solid line arrow in the figure. By causing a flow, solid-gas-liquid separation can be performed very efficiently. In addition, by creating a flow of a part of water from the gap 6, it functions to prevent bacteria, treated water and gas from flowing out of the system directly through the gap 7 in the direction of the dashed arrow. The cells and the treated water flowing from the gap 6 partially strike another solid-gas-liquid separation plate 3, and only the cells pass through the gap 7 and settle again at the lower part of the apparatus. The separation plate 3 needs to protrude below the gap 6 into the liquid. In this way, the treated water undergoes solid-liquid separation completely in the supernatant portion 8 on the upper right side of the figure, and the treated water flows out of the system via the gutter 9. On the other hand, the bacterial cells descend in the tank as shown by the solid line arrows and smoothly circulate in the tank, so that efficient contact with wastewater introduced from the wastewater inflow pipe 14 by the wastewater inflow pump 15 is always maintained. In the initial stage, the amount of generated gas is small,
When ascending turbulence is unlikely to occur and bacteria cells flow out, the generated gas collected by the gas holder 10 or a gas (nitrogen or the like) 11 containing no oxygen introduced from outside the system is piped using the pump 12. A flow can be created by venting through the bottom of the device through 5. When the operation is performed without circulating the gas, the generated gas is diffused out of the system from 13 or guided to a post-processing unit. As described above, according to the present invention, the solid-gas-liquid separation mechanism having an extremely simple structure has a sufficient capability in solid-gas-liquid separation and greatly reduces the initial cost. can do. Further, the present mechanism 16 can be installed and used in a part of the wastewater treatment reactor as shown by, for example, the hatched portions shown in FIGS. 5, 6, and 7, so that the running cost can be greatly reduced.
