As shown in FIG. 4, the purification zone 3 used in the purification device 1 of the present embodiment is arranged so as to face the side surface of the sewage sprinkling means 4 described later so that the sewage leaking from the sewage sprinkling means 4 flows down. Can be used. As shown in FIGS. 2 and 3, the purification zone 3 is configured by disposing a plurality of porous columnar bodies 32 on a water guide sheet 31. As the water-conducting sheet 31, for example, when the porous columnar body 32 is disposed and then erected and used, a known material having rigidity such as resin may be used,
When used by hanging, a soft known material such as woven cloth may be used. For the porous column 32, a porous biological carrier or the like having voids to which microorganisms for purifying sewage adhere is used. That is, as the porous columnar body 32, it is conceivable to use a sponge-like material such as non-woven fabric or polyurethane, or a water-retaining material such as ceramics.

When a sponge filter medium is deposited in layers like a conventional sprinkler type filter bed device, it is inconvenient because it is crushed by a soft sponge and becomes in an anaerobic state. However, in the present invention, the porous columnar body 32 is replaced with a water guide sheet. The soft sponge can be used without being worried about being crushed because it is disposed on 31 and supported.

いることが考えられる。As shown in FIG. 2, the porous columnar body 32 is a columnar member which basically extends in the horizontal direction. The porous columnar body 32 is arranged to face the water-conducting sheet 31 in the horizontal direction on both sides of the water-conducting sheet 31. Arrange them side by side in a row. Perforated column 3
The cross-sectional shape of 2 (in the state of being arranged on the water guide sheet 31) can be various shapes such as a spherical shape, a cubic shape, and a shape in which the bottom surfaces of two triangles are combined (substantially abacus spherical shape). As shown in FIG. 3, the porous columnar bodies 33 are connected to each other so that the narrowed portions of the cross-sectional shape are opposed to each other so as to form a constricted portion. When flowing down to the body 32, by passing through this constricted portion, it is possible to make more contact with the air and enhance the ability of microorganisms to decompose and purify sewage. In addition to the above-described structure of the connecting portion, in each of the various porous columnar bodies 32, the connecting end faces are connected with some allowance to connect them, thereby further increasing contact between sewage and air, and thereby purifying It is also possible to increase the ability. The total length of the purification zone 3 is desired to be as long as possible in consideration of purification of sewage, but is basically set in consideration of the total length of the tank 2, and the sewage sprinkling means 4 and sewage supply means, which will be described later, are provided above the tank 2. It is conceivable that the height is set to leave a sufficient space for arranging 5. Further, it is considered that the purification zone 3 is prepared in advance as a single body according to the total length of the tank 2, or a plurality of purification zones are combined in the vertical direction so as to match with the total length of the tank 2.

After the sewage has been collected to a predetermined height in 4, the sewage is allowed to overflow from each slit 41 so that a uniform amount of sewage can be supplied over the entire width of the purification zone 3. As a shape of the slit 41 formed in the dirty water sprinkling means 4, it goes without saying that a known shape other than the inverted triangle as shown in FIG. 4 can be adopted. Further, instead of the slit 41, for example, a known permeating material (not shown) may be arranged to supply a predetermined amount of sewage in the sewage sprinkling means 4 to the purification zone 3.

As the sewage supply means 5, various known forms can be adopted. For example, as shown in FIG. 1, all sewage sprinklers 4 are connected by a distribution pipe 51 to supply sewage from outside the tank 2. It is conceivable that the sewage sprinkling means 4 can be directly pulled in by supplying the sewage water to the sewage sprinkling means 4. In addition to this, for example, as shown in FIG.
A lid 53 having a distribution structure is arranged on the upper surface of the tank 2,
It is conceivable to supply sewage from above with a sprinkler 54 or the like. At this time, a plurality of through holes 55 are formed in the lid 53 having the distribution structure in accordance with the arrangement position of the purification zone 3 arranged in the tank 2, and the sewage is evenly distributed in each of the through holes 55. The upper surface of the lid 53 is provided with an inclination so as to collect. As a result, sewage can be supplied to each purification zone 3 almost uniformly. In addition, when supplying the wastewater to the purification zone 3 from the lid 53, the purification zone 3 is not covered by the lid 53.
It is conceivable to suspend and arrange it just below the through hole 55 formed in the above.

It is a means for further enhancing the purification efficiency of wastewater by activating the activity of microorganisms. A known device such as a compressor or a blower may be used as a device for sending out air. It is also conceivable to form an exhaust port (not shown) in the tank 2 in order to ensure a predetermined ventilation.
In this case, it may be possible to employ a deodorizing device (not shown) that prevents the offensive odor generated from the dirty water from leaking to the outside. Although the above-mentioned air supply means 6 has been described as a means for forcibly sending air into the tank 2, it is also possible to supply natural air simply by opening the blower opening 61.

At this time, the sewage does not flow down all at once due to the shape of the porous columnar body, but slowly flows down while sequentially passing through each porous columnar body. The sewage is decomposed and purified by the microorganisms attached to the porous columns while flowing down between the porous columns. At this time, by supplying fresh air into the tank forcibly or naturally by the air supply means, microorganisms decompose the wastewater and
The purifying action can be activated. As a result, the sewage flows down each porous column of the purification zone, and while reaching the vicinity of the bottom end of the sewage, the sewage is purified from the sewage to the treated water and accumulates below the tank.

も低く抑えることが可能となる。Since the present invention is as described above, the following effects can be obtained. <B> By adopting a purification zone using a porous column, it is possible to bring sewage and air into sufficient contact with each other, and thereby exhibit a high sewage purification property, so that the purification zone becomes anaerobic and It does not reduce the ability to decompose the pollutant components. In addition, the microbial bodies that have proliferated do not cause the anaerobic state by clogging the voids of the porous columnar body, and the permeation of sewage is not significantly deteriorated. <B> Since the purification zone has a structure in which porous columns are disposed on both sides of the water guide sheet, the purification zone can be easily installed in the purification device as compared with the conventional technique in which the filter media are arranged in layers. <C> Since the water guide sheet also serves as a support material when vertically arranging the porous columns, the sewage supplied from the upper part does not flow down as a short-circuit flow and flows down the microorganisms to purify the sewage. It is possible to efficiently flow down the arranged porous columnar body. <D> By forming a constricted portion at the connecting portion of the porous columnar members, it is possible to increase the air contact efficiency at the constricted portion of the porous columnar member, and it is possible to dramatically increase the treatment capacity of wastewater purification. <E> Since the porous columnar body is a columnar body extending in the horizontal direction, when the purification apparatus is scaled up, it can be easily dealt with by simply extending the lengthwise direction, for example. <F> Since the purification zone can be easily configured by merely disposing the porous columnar body as the columnar body on the water-conducting sheet, the manufacturing cost thereof can be kept low.
