Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sedimentation induction device used for a rectangular or circular sedimentation basin.

[0002]

[Prior art]

 For example, in a rectangular first or final settling tank, sediment is settled from inflowing wastewater. Sewage is first rectified through the holes in the rectifying plate and then settles.

[0003]

[Problems to be solved by the device]

 However, in the conventional settling basins, sewage flowed through the straightening vanes and was then allowed to flow freely throughout the basin. It was wasteful to install the device separately.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to a sedimentation induction device provided in a treatment facility configured to sediment a sediment from wastewater, the sedimentation induction device including means for generating a magnetic field, Is configured so that the sewage passes through the sewage to control the direction of the sewage to a desired location and guide the sewage.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 to 3 show an embodiment of the present invention. This example is for a rectangular sedimentation basin, where 1 is a sedimentation basin, 2 is its bottom, and 3 is a pit, respectively. An unillustrated submersible pump is provided in the pit 3, and the sediment sucked into the pit 3 is transported to the pond through a pipe.

Reference numeral 5 denotes a straightening plate, which has a large number of holes 6 ... As shown in FIG. The holes 6 ... Are formed obliquely so that the sewage passes obliquely downward therethrough. On the back side of the current plate 5, a guide plate 8 is attached which forms a guide passage 7 that is diagonally downward and is the same as the hole 6.

As shown in FIG. 3, the guide plates 8 are strip-shaped and each have a pair of upper and lower horizontal rail members, and are provided in a plurality of steps so as to extend above and below the straightening plate 5. . A cover 9 is provided on the upper side of these to prevent the sediment from floating and floating. The rectifying plate 5 is not limited to a plate-shaped member having holes and may be a mesh member. Further, the holes 6 ... May have horizontal axes. The guide plates 8 ... Are arranged so that each set has an N and S relationship, but this may be either a permanent magnet or an electromagnet. The baffle plate 5 is not essential.

FIG. 4 shows another embodiment. This embodiment also shows a sedimentation induction method using a magnetic field, in which a plurality of induction coils 10 are provided in a vertical axis. The coil 10 guides the precipitate to settle down in the direction of the broken line arrow, so that the precipitate is effectively deposited in the pit 3. The heavy objects 11 may be submerged in the pit 3 to promote the sedimentation.

FIG. 5 shows another embodiment in which the rectifying plate 12 itself is used as the magnetic field generating means. This magnetic field generating means is formed so that the holes 13 of the rectifying plate 12 have an N and S relationship, and as shown in the drawing, the precipitate is subjected to resistance by the magnetic field in the holes 13 and is in the direction of the arrow. Settle in a parabolic direction in the direction of the vertical axis.

FIG. 6 shows a rubber mat rectifying plate 15 as a magnetic field generating means. This rectifying plate 15 has, for example, the leftmost one A and the rightmost one B, if the surface of A on the B side is the S pole, the surface of B on the A side is the N pole. That is, since the magnetic field that passes between them is biased in one direction by the magnetic field, the resistance causes the magnetic field to settle down along the B side rectifying plate 15. A plurality of sheets are provided vertically and separated from each other in the front and back. When entering between the straightening vanes 15, the precipitates settle downward in the direction of the arrow and are effectively guided into the pit. In addition, although the current plate 15 is arranged at intervals in the vertical direction, it may be one in the vertical direction. The current plate 15 may be provided in an oblique direction. In that case, it does not matter whether the tilt is leftward or rightward.

FIG. 7 shows another embodiment in which the straightening vanes 20 ... Are provided in a dogleg shape and are divided into upper and lower portions and front and rear portions. Since the straightening vanes 20 ... Are arranged so as to be offset from each other in the front-rear direction, sediment is guided in the direction of the arrow D and clear water rises in the direction of the arrow U. In particular, a rubber mat is provided on the straightening vanes 20. The use allows the precipitate to settle faster in one direction.

FIG. 8 shows a settling basin equipped with straightening vanes 25, in which a plurality of ropes 26 ... Are hung on the flow side of the straightening vanes 25, and these ropes 26 ... Is. The rectifying plate 25 is not indispensable, and can be entirely configured by the guiding means 27. Further, the guiding means 27 may be arranged with ropes arranged in a horizontal direction or an oblique direction. The rope may be a net or a rod.

FIG. 9 shows the same applied to the circular sedimentation tank 30. In this case, a plurality of ropes 31 with guiding means 32 ... Are stretched diagonally in the vertical direction so as to have a conical shape. As a result, the precipitate comes to settle along the rope 31 due to the resistance and the action of these magnetic fields, and settles along the lower peripheral surface 33 having a tight inclination angle of 60 °.

FIG. 10 shows another embodiment. In this embodiment, 35 is a first settling basin, 36 is a final settling basin, and these two basins 35, 36 are of a combined tank type facing each other. Then, the pond bottoms 37 and 38 that are inclined are provided respectively, and a partition plate 39 is provided inside. Straightening vanes 40 and 41 are arranged before and after the partition plate 39, and the inflowing sewage first enters the sedimentation basin 35 through the inflow pipe 42. After that, it flows in the direction of arrow E through the flow regulating plate 40 and the guiding means (not shown).

The precipitate settles in the direction of arrow F to the pit 43, but it may reach the pit 43 along the pond bottom 38. G shows that the supernatant water first flows into the aeration tank 44 next to the settling tank 35, and the aerated water flows into the final settling tank 36 side on the other side of the partition plate 39.

Similarly, in the final settling tank 36, the flow straightening plate 41 and the guiding means separate the supernatant water and the precipitate as indicated by arrows H and I. Any of the above-mentioned embodiments may be applied to the guiding means. Also, a rubber mat with a magnet may be arranged at the bottom of the pond to guide it.

11 and 12 show additional examples. That is, a scraping device for scraping the sediment is provided at the bottom of the settling basin 50, and the scrapes produced by the device include not only mud-like ones but also falling ones. This is to be received by a skewer-shaped receiving body 52 provided on the upper part of the pit 51 so as to prevent problems with the suction pump.

[0018]

[Effect of device]

 The present invention is as described above. Therefore, since the sediment is regulated so that it does not settle in the entire bottom of the pond and settles in the pit, the collection of the sediment becomes early and a device for scraping the sediment is provided. No longer required.
