Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a purification treatment device, and more particularly to a purification treatment device for decomposing organic substances using microorganisms.

[0002]

2. Description of the Related Art Generally, in closed water areas such as lakes, ponds, dams, and ponds, where water flows little and stays for a long period of time, water-blooms etc. In the vicinity of the bottom where oxygen concentration is low, algae such as water-bloom and carcasses of various organisms rot and accumulate as sludge on the bottom, leading to water pollution. Especially in the summer, water pollution such as the above occurs remarkably, and an offensive odor is generated.

Therefore, in order to prevent water pollution in closed water bodies, conventionally, water in the upper and middle parts of the closed water bodies is supplied with oxygen by fountain and stirring to supply algae such as water-bloom and organic pollutants by microorganisms. Is oxidatively decomposed, forcedly oxidized by supplying ozone, settled and separated by a coagulant, adsorbed and removed by using an ion exchange resin or zeolite, and separated by a filtering device such as sand filter or membrane filter, and chlorine A device equipped with a packed bed filled with porous ceramics material that supports microorganisms, charcoal, activated carbon, etc. is installed near the closed water area, and a pump is used while aerating oxygen to the packed bed. Various purifying devices are known which are circulated and adsorbed or oxidatively decomposed.

In recent years, in apartment houses and commercial buildings, rainwater is stored in a closed water area and is treated to be used as medium water (for example, toilet water, fountain water, pond water, miscellaneous water, etc.). It is equipped with equipment to be used as water. In such a facility, in addition to preventing spoilage of the stored water, a purification treatment device for purifying the stored water is required,
A purifying device or the like according to the method described above is used.

[0005]

However, for example, in a pond or a storage tank in a closed water area, a mere fountain or a fountain is used for the growth of bacteria and phytoplankton accompanying the increase in water temperature from spring to summer. It is very difficult to oxidize and purify by microorganisms by supplying oxygen by stirring. Further, there is a problem that a soluble organic substance cannot be decomposed by a device for filtering, adsorbing or separating or a device for sterilizing, and a substantial purification treatment cannot be performed, which further increases the cost.

On the other hand, in the purification treatment by the aeration type purification device provided with a packed bed, a space for installing the equipment is required in a place outside the water area, and especially when it is used in an apartment house, the installation space is secured. There is a problem that it is difficult to do. Further, in the case of using a porous ceramics material as the filling layer, there is a limit in the increase in porosity and specific surface area in terms of production and strength of the porous ceramics material, and there is a limit in the amount of microorganisms supported per unit weight. However, if a large amount of porous ceramic material is used to increase the amount of microorganisms supported, the device becomes large and large-scale device installation work is required, making it more difficult to secure an installation space. I also have problems.

Further, a treatment device for treating treated water by using charcoal or activated carbon is also known, but a treatment device which treats charcoal or activated carbon by the adsorbing property surely purifies the treated water by microorganisms. In order to process, it is necessary to lengthen the contact time with the microorganisms, the apparatus becomes large and there is a problem that a wide installation space is required.

A first object of the present invention is to reduce the aerobic microbial purification process known for high efficiency purification,

A plurality of communication holes 43 are formed at substantially equal intervals. In this embodiment, the water conduit 41 and the water conduit 42 are made of pipes and have a circular cross-sectional shape, but the cross-sectional shape is
Other shapes may be used.

By forming the water conduit 41 in a loop shape, the water pressure applied to the water conduit 41 becomes uniform in the axial direction of the pipe when flowing at a low speed in the water conduit 41, and as a result, each water conduit is formed. The water pressure applied to 42 is also uniform. This allows
Treated water W0 supplied from the communication hole 43 into the storage portion 21
The flow rate can be uniform in the horizontal cross section.

The water W0 to be treated flowing through the loop-shaped pipe has a low speed (flow velocity of 0.
25 to 3.0 , more preferably 0.5 m / se
It is preferable that the flow rate is from c to 1.5 m / sec). When this flow velocity is within the above range, the best effect can be exhibited.

With such a configuration, the treated water W0 having a stable amount of water can be supplied to the treatment material 7, and highly efficient microbial purification is enabled.

FIG. 5 is a plan view showing another structural example of the water guiding means 4. Furthermore, when the amount of treated water becomes large,
It is necessary to increase the number of loop-shaped water conduits 41 to two or more within a range in which the pipe flow loss can be ignored. In this case, a pipe 44 for supplying water and a supply branch pipe that connects the water conduits 41, 41 to each other. 45, 45 can be provided to supply a uniform amount of water. Further, in order to make the water pressure in each pipe more uniform, it is preferable that the number of loop-shaped water conduits 41 be several times.

A treating material 7 is arranged above the water guiding means 4. The treatment material 7 is a carrier that carries microorganisms, and the carrier includes a porous body, such as porous ceramics or activated carbon. Charcoal is preferably used. In this embodiment, charcoal is used,
Particularly preferably, medium-high temperature carbonized black coal is used. This is because charcoal is weakly alkaline, has an ionized mineral content, and is provided with an environment in which aerobic microorganisms can easily propagate.
Microorganisms (for example, bacteria, protozoa, fungi, etc.) propagate on such charcoal, and these microorganisms capture filth (organic matter) in water and decompose, metabolize, and absorb water and gas (CO ₂ ) and inorganic substances (NO ₃ , SO ₄ , PO _4, etc.) are decomposed and purified.

Further, a lid-shaped sheet material 32 is covered from above the water distribution means 5, and a lid 23 is covered, and the container is liquid-tightly sealed. A degassing means 8 is provided in the central portion of the lid body 23. The gas venting means 8 is composed of a hole 81 formed in the center of the lid 23 and a valve. By opening the valve, the gas generated in the storage portion 21 by the purification process is discharged. In this embodiment, since the water to be treated W0 is sent from the outside into the storage body 2 by the pump P, the pressure in the storage portion 21 is high and a force is applied in a direction to push the lid body 23 upward. There is. In this state, the vicinity of the center of the lid body 23 is curved and rises, and gas is accumulated in this vicinity. Since the hole 81 of the degassing means is formed at the position where the gas is collected, degassing becomes easy.

Next, the structure of the container 2 will be described. The box body 22 constituting the storage body 2 includes three bottom surface members 2
21 and a side surface member 222 forming a side surface, and the lid 23 includes three ceiling members 231.
Each member has a flange portion 24 at its end, and a bolt 25 that penetrates a hole 241 formed in the flange portion 24.
The box body 22 and the lid body 23 are configured by being fastened by.

For example, the bottom surface is formed by arranging three bottom surface members 221 in parallel and connecting and fixing the long side flange portions 24 with bolts 25. The lid 23 also
It is configured by arranging three ceiling members 231 in parallel and connecting and fixing the long side flange portions 24 with bolts 25. Further, as shown in FIG. 6, a connecting member 26 having a transverse cross-sectional shape bent at a right angle is attached to the connecting portion of the side surface member 222 constituting each side surface of the box body 22, and the side surface member is abutted. 222 of short side flange portion 222
Then, the respective side surfaces are overlapped with each other and fastened by the bolts 25, thereby connecting and fixing the adjacent side surface members 222.

Next, the structure for connecting and fixing the box body 22 and the lid body 23 will be described. FIG. 7 is an enlarged cross-sectional view of a connecting portion between the box body 22 and the lid body 23. As shown in FIG.
At the open end of the box-shaped sheet material 31, a fastening margin 311 folded back to the outside is provided.
A hole 312 through which the bolt is inserted is formed. The tightening margin 311 is provided on the long side flange portion 24 of the side member 222.
The lid-like sheet material 32 is placed on the
Will be posted. A fastening margin 321 is also provided at the end of the lid-shaped sheet material 32, and a hole 322 through which a bolt is inserted is formed in the fastening margin 321. Also, the ceiling member 2
A hole 232 for inserting a bolt is formed at an end portion of the lid body 23 configured by 31. The bolt 25 includes a hole 232 of the lid body 23, a hole 322 of the lid-shaped sheet material 32, and a packing 33.

The operation of the purification processing apparatus 1 configured as above will be described. This device, when disassembling the container 2,
Since it can be disassembled into a rectangular plate-like member and the liquid-tight state is maintained by the sheet material 3, it can be easily installed and can be easily installed even in a narrow place. For example, in the case of retrofitting to an existing facility, there is a case where there is an installation space, but the device is too large to be moved to the installation space. However, in the purification treatment device 1 of the present invention, the device is disassembled. As a result, the size restriction during transportation was suppressed.

The purifying apparatus 1 is filled with water to be treated and used as a full water. Then, in order to maximize the treatment capacity by prolonging the time in which the treatment material 7 is brought into contact with water, the flow rate of the supplied water to be treated is 0.5 to 0.5.
10 cm / min , preferably 1-6 cm / min
And more preferably 3 to 5 cm / min . If the speed is higher than this speed, it becomes difficult for the aerobic microorganisms to capture the dirt, and the purification efficiency decreases.

Further, in order to make the treatment material 7 act uniformly on the water to be treated, the flow of the water supplied from the water guiding means 4 has a flat cross section (the storage section 21 is a horizontal surface (a plane including the water guiding channel 41). It is preferable that it is uniform within a cross section (which appears when cut by a plane parallel to), and the homogenization is further achieved by forming the water conduit 41 into a loop. In particular, in this device, since it is a treatment with microorganisms, it is necessary to keep the flow velocity low, and an uneven flow velocity causes
The slow part occurs, and the fast part reduces the purification efficiency, which causes a significant reduction in the purification efficiency of the device.
In the present invention, by using the water conduit 41 as a loop, it is possible to obtain a uniform flow velocity while keeping the flow velocity low.

Since the water flow is set so that the water to be treated rises from the lower side to the upper side, when treating water warmed in a pond or the like in the summer, the water to be treated is treated in the direction of convection of the water. It is possible to realize the flow of the water to be treated which has less stagnation because the directions of the water flows match. In addition to the above configuration, the water conduit 41 may be arranged in parallel, or as shown in FIG. 8, the water conduit 41 may be arranged radially and the pump P may be provided in the purification processing apparatus. .

Further, since the water to be treated is fully filled in the storage portion 21, the water to be treated can be flowed from the water guiding means 4 to the water distributing means 5 without being affected by the arrangement posture. . For example, as shown in FIG. 9, even if the storage bodies 2 are arranged vertically, the same processing capability can be exhibited.

Further, as shown in FIG. 10, the water guiding means 4 may be connected not to the discharge port of the pump P but to the suction port so that water flows in the opposite direction. Further, by disposing the purification treatment apparatus 1 of the present invention below the water storage section 10 to supply the water to be treated to the purification treatment apparatus 1 by utilizing the water pressure, the load on the pump P is reduced. . In this case, the supply amount of the water W0 to be treated may be adjusted by the flow rate adjusting valve V as necessary.

As another embodiment, as shown in FIGS. 11 to 13, the water guiding means 4 may be composed of only a water guiding channel 41 formed by forming a pipe in a loop shape.
In this case, the communication hole 43 is formed in the water conduit 41.
