FIG. 4 shows another embodiment. This embodiment also shows a sedimentation induction system using a magnetic field, in which a plurality of induction coils 10 are provided along a vertical axis. This coil 10
As a result, the precipitate is induced to settle in the downward direction, which is the direction of the dashed arrow, and the precipitate is effectively settled in the pit 3. The heavy objects 11 may be submerged in the pit 3 to promote the sedimentation.

FIG. 5 shows a reference example in which the current plate 12 itself is used as a magnetic field generating means. The magnetic field generating means includes a rectifying plate 1
Each of the two holes 13 is formed so as to have a relationship of N and S, and as shown in the figure, the sediment is subjected to resistance by the magnetic field in the hole 13 and settles in a pit direction, which is the direction of the arrow, so as to draw a parabola. .

FIG. 6 is a reference example in which a current plate 15 made of rubber mat is used as a magnetic field generating means. This current plate 15 is, for example, a left end A and a right end B,
If the surface on the side is an S pole, the surface on the A side of B is an N pole. That is, the one passing therethrough is urged in one direction by the magnetic field, so that it sinks along the B-side rectifying plate 15 due to its resistance. A plurality of sheets are provided vertically apart from each other, and when they enter between the flow straightening plates 15, the sediment sediments downward in the direction of the arrow, and is guided well into the pit. In addition, although the rectifying plates 15 are arranged at intervals in the upper and lower directions, one rectifying plate 15 may be used. The current plate 15 may be provided in an oblique direction. In this case, it does not matter whether the vehicle is tilted left or right.

FIG. 7 shows a reference example in which straightening plates 20 which are divided into upper and lower sides and front and rear in a U shape are provided. Since the current plates 20 are displaced back and forth, sediment is induced in the direction of arrow D and clear water rises in the direction of arrow U. In particular, a rubber mat is used for the current plates 20. This allows the sediment to settle faster in one direction.

FIG. 9 shows a reference example in which the same is applied to a circular sedimentation basin 30. In this case, a plurality of the ropes 31 with the guiding means 32 are stretched diagonally up and down so as to form a conical shape. As a result, the sediment is settled along the rope 31 by the resistance and the action by the magnetic field, and settles along the lower peripheral surface 33 having a steep inclination angle of 60 °.

FIG. 10 also shows a reference example. In this reference example, 35 is a first settling basin, 36 is a final settling basin, and both ponds 35 and 36 are of a congruent tank type. Each of the tanks has inclined bottoms 37 and 38 and a partition plate 39 inside. Partition plate 39
Before and after, flow straightening plates 40 and 41 are arranged, respectively. First, inflow sewage first enters the sedimentation basin 35 through the inflow pipe 42. After that, it flows in the direction of the arrow E through the current plate 40 and the guiding means (not shown).

The precipitate settles in the direction of arrow F to form a pit 43.
It sinks to the pit 43 along the bottom of the pond 38 in some cases. G shows a state in which the supernatant water first flows into the aeration tank 44 next to the sedimentation basin 35, and the aeration here flows into the other side of the partition plate 39 toward the final sedimentation basin 36.

In the final sedimentation basin 36, similarly, the current plate 4
1 and the deriving means, as shown by arrows H and I, are separated into supernatant water and precipitate. Note that any of the above embodiments may be applied to the guiding means. Also, a rubber mat with magnet may be arranged on the bottom of the pond to guide the pond.

FIGS. 11 and 12 also show a reference example. That is, a scraping device for scraping the sediment is provided at the bottom of the sedimentation basin 50, and the scraped material by the device includes not only a mud but also a falling object. This is received by a skewer-shaped receiving body 52 provided above the pit 51 so as to prevent a trouble of the suction pump and the like.

[Effect of the Invention] This invention is as described above.
The invention described is plate-shaped and in a parallel relationship with each other in the plate surface.
A lot of holes are penetrated and the board surface becomes vertical
Installed above the sediment receiver in the processing equipment
Rectification by passing the flow of sewage from a certain upstream side through the hole
So that it flows out downstream as a slow flow
In a sedimentation guidance device provided with a rectifying means, the rectifying means
All of the holes are formed as downward-sloping holes
In addition, means for generating a magnetic field are formed in the holes.
As compared to the method in which magnets are arranged in horizontal holes to control the flow of sewage water into a downward flow, the flow energy damping effect of the downwardly inclined holes and the damping effect of the magnetic field cooperate with each other. This ensures that the downflow is generated earlier and can be effectively guided into the sediment receptacle. Rather than making the flow direction of sewage horizontal and applying a magnetic field between them, instead of making the flow direction of sewage fall down and inclining to apply a magnetic field, the sewage flows out of the hole, so that it flows out horizontally, At the beginning of the outflow, for example, assuming that the vehicle travels 3 cm, in the case of the invention of claim 1, for example, since the water flows out at an angle of 30 ° lower than the horizontal line, it is 3 at the beginning of the outflow.
cm, 2 cm in the downward angle direction. That is, in the invention of claim 1, since the horizontal component travels for about 3 cm, which is a longer time than in the case of horizontal outflow, the energy attenuation during that time is large and the descending action is large. As this descends, the angle of the descending slope becomes gradually steeper, so that the effect becomes greater, and the sediment sinks to a place not far from the outflow. In particular, as in the invention of claim 2,
The rectifying means is constituted by a porous rectifying plate and a guide plate in which strip-shaped members are arranged in a crossbar shape on the downstream side of the rectifier plate. The speed of the sewage is slowed down by coming into the widened flow path formed between them, and since the magnetic field is generated in that state, the speed is further slowed down and the downflow is apt to occur.
The invention according to claim 3 is a sedimentation guidance device arranged on a pit of a sedimentation basin, which is a processing facility, and a plurality of induction coils whose longitudinal axes are oriented vertically are provided so as to correspond to a region above the pit. The coil is characterized by the fact that it is a means of generating an electromagnetic field, so the shape action of the spiral coil captures the flow of sewage and effectively decelerates it. However, since a magnetic field is generated, a downward flow is effectively generated. The invention according to claim 4 is a sedimentation guidance device which is disposed on a pit of a sedimentation basin as a treatment facility, and a hanging member such as a rope or a rod having a vertical axis center is provided so as to correspond to an area above the pit. In this case, a plurality of guides, which are permanent magnets, are provided in each of these suspending members so as to be vertically spaced apart from each other. The deceleration is effectively generated by catching with a plurality of suspension members, and a magnetic field is generated in that state, so that a downward flow is effectively generated.
