DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. 1 and 2 show an embodiment of the present invention. This embodiment is provided while flowing from a home or a factory to a river, and is provided in place of or in combination with a conventional merged processing tank.

[0006] Reference numeral 1 denotes an outer pipe (processing tank body).
As shown in FIG. 4, resin pipes used for civil engineering collection and drainage pipes (for example, high-density polyethylene finished in a corrugated cross-sectional shape, or a corrugated cross-section made of metal, In addition to using polyethylene molded and molded) (trade names: Kana pipe, Kanaflex Super, etc.), use commercially available products such as cast iron pipes shown in Fig. 3 and concrete pipes (not shown). Can be.

In the pipe 1, a space forming body 2 is united.
Inserted in a cassette type. The formed body 2 is a pipe 1
A plate-like vertical that partitions the inside left and right and extends long in the longitudinal direction
Partition plate 3 and mounting flanges provided on both upper and lower ends thereof
4 and 4, and in the longitudinal direction of the vertical partition 3
Means that a plurality of horizontal partition plates 5 that cross the inside of the pipe 1
It is provided. And the vertical partition plate 3 and the horizontal partition plate 5
Are provided with through holes 6 in place.

Reference numeral 10 denotes a first sedimentation / separation tank, and 11 denotes a second sedimentation / separation tank. After the domestic wastewater or the like flows into the first sedimentation / separation tank 10 to perform the sedimentation / separation operation, the upper layer water is passed through the through hole 6.
Into the second precipitation / separation tank 11.

[0009] From the second sedimentation separation tank 11, it flows into the first contact aeration tank 13 through the through hole 6. Here, the internal connection
Purification is performed by the microorganisms of the contact material 14 and the air by the air supply means 15.

The upper layer water from the first contact aeration tank 13 flows into the adjacent second contact aeration tank 17 through the through hole 6. Here, the same purification is performed. The pipe of the air supply means 15 and the pipe 16 of the microorganism supply means are formed through an insertion pipe 18 provided orthogonal to the outer pipe 1.

Then, after being led to the first and second precipitation tanks 20 and 21, it is led to the disinfection tank 22, and as a whole,
When viewed from above, a meandering flow route is formed.
ing. An air lift pump and a rectangular overflow weir are provided in the sedimentation tanks 20 and 21, and what has passed the overflow weir is brought into the next disinfection tank 22.
The illustration is omitted. The treated water from the disinfecting tank 22 flows to the river as shown by the arrow.

Although the outer pipe 1 needs to be connected to the front and rear, it can be connected by a flange. As shown in FIG. 3, when the cast iron pipes 23 are connected to each other, a space is formed at the same time. The flange 25 of the body 24 is
If it is sandwiched between the flanges 26, there is an advantage that the fixing is surely performed.

As shown in FIG. 4, when an outer pipe 30 having a corrugated cross section is used, the outer pipe 30 can be connected by using a connection member 31 of a half-split type.

Further, as shown in FIG. 5, a T-joint 36 may be used to connect the outer pipes 35 to each other. Sometimes a cruciform joint is used.

When the present apparatus is installed in a narrow place, as shown in the plan view of FIG.
A plurality of 0s may be connected in parallel by one or a plurality of reversing joints 41 and provided in parallel. According to this,
Even in a small place, a long and large-capacity device can be obtained. Note that, as the contact filter medium 14, debris of a resin pipe or a metal pipe may be used.

FIG. 7 shows an additional embodiment. An example of another device connected to the outlet 46 of the processing device 45 is shown. That is, the first route 47 and the second route 48 are divided into two, and the first route 47 flows out into the river, but the treated water is discharged from the second route 48 into the soil through the through holes 49. In this case, the through holes 49 may be clogged, but the second route 4 may be used to eliminate the clogging.
The brush 50 may be provided so as to circulate in the brush 8. The brush 50 moves in the direction of the arrow, follows the path from the left side to the right side perpendicular to the paper surface, and moves again in the second route 48 in the direction of the arrow.

FIGS. 8 and 9 also show additional examples. In this example, the microorganism propagation material 55 is formed by attaching a vinyl film 57 to a wire 56, and is circulated to propagate microorganisms in a processing pipe 58 as shown in FIG. Instead of pouring a disinfectant chemical into the pipe 58 to kill the microorganisms, an ultraviolet sterilizer 59 may be provided to sterilize the microorganisms while keeping them alive as shown in FIG.

[0018]

[Effect of the invention] This invention is as described above.
Sewage treatment will be very effective. Especially,
The sewage is treated in a straight line by treating
Because it flows in a meandering shape instead of flowing, the same pipe
Even though the length is doubled, the processing length is doubled.
Precipitates those that do not easily settle, and also has a contact aeration and disinfection effects.
Will be effective and reliable. By equipping such a sewage treatment apparatus at a stage before the original treatment facility, not at a later stage, the functions of the original treatment facility can be sufficiently exhibited, and the purification of the sewage can be advanced as a result. .
