Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension type water purification device used in a sedimentation pond of a water purification plant.

[0002]

2. Description of the Related Art FIG. 37 shows a general flow sheet of a water purification plant for water supply and the like, 1 is a landing well, 2 is a chemical mixing basin, 3 is a coagulation sedimentation basin, 4 is a trough, 5 is a filtration basin, 6 Is a water purification pond. In the sedimentation basin 3 of this type of water purification plant, the sedimentation efficiency in sedimentation and capture of suspended solids in water is determined by the water area of the sedimentation basin 3.

That is, the relationship between the sedimentation rate of suspended solids and the water area is generally expressed by the equation of water area load factor V ₀ = Q / A. In this case, Q is the water amount and A is the water area. Therefore, if the water amount Q is made smaller or the water area A is made larger, the water area load factor V ₀ can be made smaller and the precipitation efficiency can be improved.

However, it is out of the question to reduce the amount of water in the settling basin 3 of the water purification plant, and to increase the water area A, the area of the settling basin 3 must be doubled or tripled. No, it is irrational.

Therefore, in order to reduce the area of the settling basin 3 and to treat a large amount of water, a settling device having a rigid structure as shown in FIG. 38 or 39 is conventionally used. In the case of FIG. 38, a perforated plate type straightening wall 7 is provided in the center of the sedimentation basin 3 to divide it into an upstream side 8 and a downstream side 9, and the upstream side 8 is not equipped with anything and the downstream side 9 is , The settling device 10 close to the straightening wall 7
Has been installed.

This settling device 10 has a block-like rigid structure in which a large number of parallel trapping plates 10a are densely assembled at an angle of 60 degrees so that water flows as an upward flow or a cross flow. It is placed on the diversion wall 11 that also serves as a stand on the downstream side 9
It is attached to 12. Air pipes 13 for aeration are provided on both sides of the baffle wall 11.

In the settling device 10 in the case of FIG. 39, a large number of square pipes 14 are densely connected at an inclination angle of 60 degrees to form a Hannicome-like square pipe group 15, and the square pipe group 15 is crossed. A large number of sets are arranged in a block-like rigid structure, and a trough 16 for supernatant outflow is arranged above the rigid structure. This sedimentation device
10, the water through the Hanikomeu square pipe group 15 as an upward flow, capture the suspended matter in the water on the inner surface of each pipe 14,
Clear water flows out from trough 16.

[0008]

The conventional settling device 10 is
Since each of them has a complicated rigid structure, it can be installed only locally in the sedimentation basin 3, for example, it is installed in the upper layer on the downstream side 9 of the sedimentation basin 3, so that there is a limit to the improvement of the surface load factor.

In particular, since it is necessary to secure a cleaning space below the sedimentation basin 3, the sedimentation device 10 is installed in the upper layer and the diversion wall 11 is provided in the lower layer. Since the cross-sectional area is narrowed, the flow velocity of water becomes faster, and the lower layer side does not contribute to the improvement of the surface load factor, which is a waste.

Further, in each settling device 10, since the trapping plate 10a and the pipe 14 are arranged at an inclination angle of 60 degrees, the effective area thereof is 1/2 of the plate area of the trapping plate 10a and the pipe 14 (cos 60 degrees = 0.
It becomes 5), and there is a drawback that the material cannot be fully utilized. Furthermore, there are problems in maintenance, and it is difficult to carry out partial repairs, equipment cleaning, and pond bottom cleaning. For example, in the case of FIG. 38, the suspended matter adhering to each capture plate 10a can be expected to slide down at an angle of 60 degrees, but there is a sufficient risk of blocking the gap between each capture plate 10a. Therefore, it is necessary to clean the lower part of the settling device 10 by aeration or the like, and the cleaning is complicated.

In the case of FIG. 39, since the square pipe group 15 has a densified rigid structure like a hanikome, it is very difficult to manage the sanitation inside the sedimentation apparatus 10. Moreover, in this case, since the flow of water becomes an upward flow, there is a disadvantage that the sedimentation velocity of the floating material itself is offset by the upward flow.

Further, all of the conventional settling devices 10 have a rigid structure and have fixed characteristics with respect to flocculation operation, treated water amount, water temperature, and water quality fluctuation, so that the completeness is low as a precise and rational system. . In addition, the structure of the sedimentation device 10 itself is complicated, and there are problems in terms of initial cost, construction period, and the like.

In view of the above conventional problems, the present invention is a movable type in which a plurality of purification members arranged substantially parallel to each other in the vertical direction are suspended in a pond by suspension members, and the purification members can be changed in angle. By adopting a flexible structure, the overall structure of the device can be simplified and the initial cost can be reduced, and floating substances can be captured by precipitation, charge attachment and contact attachment, and deodorization, biological treatment, etc. can be made more efficient, or The objective is to facilitate maintenance such as partial repairs, cleaning of equipment, and cleaning of the bottom of a pond.

A large number of small holes 85 are formed in the straightening vane 81 in the straightening vane 81, and the straightening vane 82 has a blind plate shape.
These straightening vanes 79 to 82 are vertically connected via a connecting member 86 such as a hook, and the uppermost straightening plate 79 is beamed through a hanging member 87 such as a hook so that the whole is in a vertical state. Suspended at 88. The beams 77 and 88 are installed between the left and right guide channels 65.

In the above construction, the function of mixing the chemicals in the water in the chemical mixing pond 20 and then sedimenting and trapping the floating substances floating in the water will be described. Chemical mixing pond
The water of 20 flows into the sedimentation basin 21 through a large number of rectification holes 23 formed in the rectification wall 25, and flows laterally in the sedimentation basin 21 toward the downstream side. Then, while the water flows laterally in the settling basin 21, floating matters such as mud floating in the water are settled and settled on the trapping plates 44 of the settling unit rows 29 to 33 and captured.

By the way, the beams 40 are erected at intervals of 600 mm from the end of the sedimentation basin 21 to 60% of the water area of the sedimentation basin 21 near the surface of the water, and each beam 40 is divided into two by one by the center allocation at intervals of 600 mm. The arms 52 of the set are welded together, and the sedimentation units 41 to 43 are suspended from the arms 52 via the four suspension members 45. Each settling unit 41-43 is provided with 20 vertical and horizontal 500 trap plates 44 at 10 mm intervals.

In this case, between the sedimentation units 41 to 43,
Assuming that the equipment functional clearance ratio due to the clearance between the sedimentation units 41 to 43 and the side wall 39 and the bottom wall 72 of the sedimentation tank 21 is 0.7, the area of the capture plate 44 is larger than the water area of the sedimentation tank 21. 0.6
× 20 × 0.7 = 8.4. Therefore, the surface load factor (water surface load factor) V ₀ is approximately 1/8, so the removal rate of suspended matter is 8
Doubled.

This means that since the capture plates 44 are used substantially horizontally, the area of the upper surface of each capture plate 44 is effective in reducing the load factor. In addition, each capture plate 44
Is substantially horizontal, the flow of water in the sedimentation basin 21 is a transverse flow, and each capture plate 44 itself also has a rectifying effect of a transverse flow. Therefore, each capture plate 44 has an uneven flow of water in the sedimentation basin 21. At the same time as having the function of controlling the above, there is an element that reduces the sedimentation velocity of the suspended matter itself in the case of conventional upward flow, whereas
The cross-flow has the advantage that the sedimentation velocity can be utilized.

The water flowing into the settling basin 21 first passes between the trap plates 44 of the upper and lower layer settling unit rows 27 in the first row, and the floating material floating in the water is trapped across the upper and lower layers.
Captured by 44. Then, of the water that has passed through the upper and lower layer settling unit row 27, the water in the upper layer portion passes between the trap plates 44 of the second upper layer settling unit row 28, and the suspended matter in the water is trapped. Further, since the lower layer water contains relatively heavy suspended matter, the heavy suspended matter settles on the bottom wall 72 while passing under the upper sedimentation unit row 28.

The water which has passed through the upper and lower layer regions of the upper settling unit row 28 flows toward the lower settling unit rows 29 and 30 of the third and fourth rows. At this time, since the suspended solids of the upper layer water have already been captured while passing through the two settling unit rows 27 and 28 in the preceding stage, they are passed through the upper side of the lower layer settling unit rows 29 and 30 and the trapping plate 44 The sedimentation is not actively captured by. On the other hand, the water that has passed below and below the upper layer settling unit row 28 in the second row passes between the trapping plates 44 of the lower layer settling unit rows 29 and 30, during which the suspended solids in the water settle and settle. To capture.

That is, since the suspended matter in the water becomes a lateral flow in the settling tank 21 and gradually settles while flowing in the lateral direction, first of all, the trapping plates of the upper and lower sedimentation unit rows 27 of the first row.
After capturing the suspended matter over the entire upper and lower layers at 44, the second
Floating substances on the upper layer side are captured by the respective capture plates 44 of the upper layer settling unit column 28 in the second column. Then, in the third and fourth rows, the suspended matter further sinks, so that the trapped plates 44 of the lower layer sedimentation unit rows 29, 30 capture the suspended matter that has settled to the lower layer.

Almost all the suspended matter in the water can be captured after passing the fourth row, but this water is subsequently passed through the fifth and sixth rows of the upper and lower sedimentation unit rows 31, 32, and the seventh row. The particles are passed between the capture plates 44 of the lower layer settling unit row 33 of the row, and the fine floating substances are further sedimented and captured by the capture plates 44 of the settling unit rows 31, 32, 33. As a result, all of the sedimentary suspended matter can be almost certainly captured in the suspended matter in the water. Then, the trapped suspended solids are deposited on each trap plate 44, and the amount of deposition is maximum on the trap plate 44 side of the upper-layer sedimentation unit row 27 in the first row and gradually decreases as it moves to the downstream side. .

A baffle plate unit 37 including a side baffle plate 71 and a bottom baffle plate 73 is provided between the upper and lower layer settling unit rows 31 and 32 in the fifth and sixth rows. This is to improve the functional clearance ratio of the equipment, which prevents water from flowing to the side and below the sedimentation unit rows 31 and 32.

The water that has passed through the seventh row flows downward as a downward flow between the downward flow regulating plates 59 of the upper and lower downward flow regulating unit rows 34, and also downwards in the upper downward flow regulating unit row 35. A downward flow flows between the straightening vanes 60. Therefore, while passing through these two rows of downward rectifying unit rows 34 and 35, almost all the water in the upper and lower layers is rectified in a downward flow and then flows to the final upper and lower layer reverse rectifying unit row 36.

Then, the clear water in the upper layer flows as an upward flow through between the upward flow straightening plates 61 of the upper and lower reverse flow straightening unit rows 36, and the water in the lower layer passes between the downward flow straightening plates 62 and flows downward. It flows countercurrently. Therefore, the flow velocity distribution of water can be adjusted by these rectifying unit rows 34 to 36, and the upper and lower layer reverse rectifying unit rows 36 separate the water in the upper and lower layers into an upward flow and a downward flow, so that clear water can be easily taken out. .

Further, in the current plate unit 38, each of the current plates 79 to
By changing the hole diameter of 82, the hole diameter of the upper straightening plate 76 is maximized, and the hole diameter is reduced as it moves downward with the straightening plates 80, 81, and the lowermost straightening plate 81 is made into a blind plate shape. Despite the fact that the straightening holes 24 of the straightening wall 26 have substantially the same diameter both in the upper and lower sides, the flow velocity distribution is controlled to pass the supernatant liquid through the straightening holes 24 of the straightening wall 26 to the filtration pond 22. Can be taken out to the side.

The suspended matter trapped by each trapping plate 44 is sludge-like and accumulates on each trapping plate 44, so it is regularly cleaned and removed. In this case, the lock pin 70 is pulled out to unlock the beam 40, the pipe 89 is inserted into the handle 67 of the beam shaft 64 as shown in FIG. 11, and the beam 40 is rotated around the beam shaft 64 via the pipe 89. Is rotated in the direction of arrow a.

Then, the beam 40 is rotated, and one side of the two hanging members 45 hooked on the tip of the arm 52 is lowered and the other side is raised, so that each capture plate 44 is inclined obliquely from the horizontal state. Then, when the beam 40 is rotated, for example, 90 degrees and fixed by the lock pin 70, the capturing plate 44 and the hanging member 45.
Since there is a margin between the trap 50 and the restraint tool 50, the trap plates 44 incline and hang down to near the vertical state, and the suspended solids on the trap plates 44 naturally start from the time when the slant angle exceeds 60 degrees. Begins to slide, falls downward, and precipitates and accumulates on the bottom wall 72. By simply rotating the comb beam 40, the suspended solids on the trap plate 44 can be removed, and cleaning is very easy.

Since the beam 40 in the settling unit rows 27 to 33 needing to be cleaned can be operated, the settling unit rows 27 to 33 can be individually cleaned as needed and management is easy. Is. For example, although the settling unit rows 27 to 33 are in multiple stages, the amount of suspended solids accumulated is the first settling unit row.
Since 27 is the maximum and decreases as it moves to the downstream side, if the first settling unit row 27 is cleaned, for example, about once or twice a month, the number of times of cleaning can be reduced as it moves to the downstream side.

If the settling unit row 27 is cleaned, when the sediment floating material falls and sinks, a part of it floats up and flows to the downstream side together with the flow of water. However, since there are many settling unit rows 27 to 33 on the downstream side, the suspended floating material can be captured again by the trapping plate 44 of the settling unit rows 27 to 33, and the downward rectifying plates of the rectifying unit rows 34 and 35 can be captured. Since it can be rectified and suppressed by the downward flow by 59, suspended matter floating up during cleaning will not flow out.

When cleaning the subsequent settling unit rows 32, 33, etc., the number of steps in the settling unit rows on the downstream side is small, but the amount of suspended solids is small, and the rectifying unit rows 34, 35 are suppressed. As such, it is possible to prevent the outflow of suspended matter as well. Therefore, for each sedimentation unit row 27 to 33, efficient cleaning is possible with the least number of cleanings,
It can be used for a long period of time without floating suspended matter,
The continuous use period of the sedimentation tank 21 can be extended.

When the settling basin 21 is drained and cleaned, each settling unit row 27-33, rectifying unit row 34-36,
If the baffle plate unit 37 and the baffle plate unit 38 are pulled upward, a sufficient cleaning space can be secured on the pond bottom side.
In this case, each settling unit row 27 to 33 has a flexible structure in which a large number of capture plates 44 are suspended by four flexible suspending ropes 45, and the other rectifying unit rows 34 to 36 and the like are also the same. Because of the flexible structure, they can be easily pulled up.

Particularly, a settling unit row 27-33 and a rectifying unit row 34-36 provided with a large number of capturing plates 44, rectifying plates 59, 61, 62.
Is an independent sedimentation unit 41-43, rectification unit
Since 56 to 58 are lined up in the left-right direction, the weight of each individual can be reduced and it is very easy to pull up.

When the trapping plate 44 is washed, the trapping plate 44 is made vertical while the settling units 41 to 43 are suspended, or the beam 40 is rotated 90 degrees in the suspended state. After locking with the lock pin 70 to make each capture plate 44 vertical, water can be sprayed from above to wash them. For this reason, it is possible to efficiently clean them in an extremely short time, despite the large number of trapping plates 44. The same applies to the rectifying unit rows 34 to 36 and the like.

When a part of the trapping plate 44 is damaged, only the settling unit 41 to 43 having the trapping plate 44 is removed, and the trapping plate 44 is replaced or repaired, or the settling unit 41 to
43 Replace itself. In this case, by removing the eye portion 51 at the upper end of the suspension member 45 from the locking groove 53 of the arm 52, each sedimentation unit 41 to 43 can be individually removed, so that it can be easily repaired or partially repaired. It is easy, and there is no need to drain the settling tank 21 each time.

Further, in this embodiment, each settling unit row 27-
33 is a suspension type by the beam 40, and there are a large number independently of the flow direction of water in the settling basin 21, and each settling unit row 27-33 has a plurality of independent settling units 41-43 in the left-right direction. Since they are arranged side by side, as shown in FIG. 1, the capturing plates 44 can be freely arranged in necessary layers such as the upper and lower layers, the upper layer and the lower layer for each row.

Therefore, in consideration of the flow of water in the settling basin 21 and the like, the number of the trapping plates 44 is minimized and one trapping plate 44 is used.
The trapping plates 44 can be arranged so that the trapped rate (removal rate) of the suspended matter per hit is maximized. Of course, the water temperature,
It is possible to widely and easily deal with changes in water quality, quality of coagulant and injection amount, and changes in water amount.

Further, the suspending depth of each sedimentation unit 41 to 43 can be adjusted from the lower layer to the upper layer and from the upper layer to the lower layer only by adjusting the length of the suspending member 45. Gives you more freedom. Further, since the sedimentation units 41 to 43 are independent of each other and are separated for each beam 40 and are dispersed and independently arranged as a whole, the degree of freedom of the parallel layout is extremely large.

12 to 15 show a second embodiment of the present invention. As shown in FIGS. 12 to 14, each capture plate 44 has a horizontal fin 90 and a vertical fin 91 above and below the downstream end in the water flow direction.
And are provided. The horizontal fins 90 are arranged in parallel with each other in the left-right direction with a gap between them and the upper surface of the trapping plate 44, and are formed integrally with the trapping plate 44 via the bent portions 92 at both ends. The vertical fins 91 are arranged substantially perpendicular to the lower surface of the capturing plate 44, and are integrally formed with the capturing plate 44 together with the reinforcing ribs 93 at both ends.

In this way, when capturing the suspended matter,
The water that flows laterally between the upper and lower capture plates 44 hits the vertical fins 91 on the lower surface of the upper capture plate 44 as shown in FIG. 12, and the flow direction changes downward as shown by the arrow, so floating matter floating in the water Tend to settle, and settle and deposit on the trapping plate 44 and the horizontal fins 90, so that the trapping rate of the suspended matter is improved.

When the beam 40 is rotated during cleaning, each trapping plate 44 tilts as shown in FIG. Then, the suspended solids on the capturing plate 44 are separated and descend downward along the capturing plate 44. At this time, the floating suspended matter flows up to the upper end side of the trapping plate 44 together with the upward flow of water, but there is a horizontal fin 90 with a gap above the downstream end of the trapping plate 44. The lower surface of the horizontal fin 90 can suppress the soaring. Further, the floating matter that has risen over the horizontal fins 90 can be suppressed by the vertical fins 91 on the lower surface of the upper capturing plate 44. For this reason, there is an advantage that re-floating due to soaring of suspended solids during cleaning can be suppressed.

16 to 18 show a third embodiment of the present invention in which a long hole 44a is provided in the central portion of a trapping plate 44 in the direction orthogonal to the flow direction of water. If the long hole 44a is provided in the central portion of the trap plate 44 in this way, when the trap plate 44 is inclined and cleaned as shown in FIG. The suspended solids fall downward from the long holes 44a. Therefore, even if the trapping plate 44 is upsized to 1000 mm × 1000 mm or the like, the suspended solids can be quickly dropped and cleaning is facilitated.

If long holes 44a are provided in the trap plates 44, the floating substances pass downward through the long holes 44a as shown in FIG. By making the interval small, it can be captured by the lower capture plate 44, so there is no problem. In addition, when enlarging the capture plate 44,
It is desirable to provide reinforcing ribs 44b at both ends thereof. In this embodiment, the capture plate 44 is reinforced by the vertical fins 91 and the reinforcing ribs 44b. The reinforcing rib 44b has a function of rectifying water as well as reinforcing.

Further, the beam 40 can be installed below the water surface. In some cases, it may be necessary to install it below the surface of the water because of the relationship with the device that automates the cleaning of the bottom of the pond. Each beam 40 may be rotated manually by a drive source such as a gear motor, a damper motor, a cylinder or the like, in addition to being manually operated by the handle 67. In that case, it is also possible to connect the driving source and each beam 40 and to simultaneously operate the beams 40 in a plurality of rows by one driving source.

The drive source may adopt a method of analyzing conditions such as water quality, water amount, water temperature, etc. and performing remote control by wire or wireless, automatic proportional mode control, or intermittent two-position control by a timer. You may. For example, when the water volume is detected by the water meter and if it increases, the control unit activates the drive source to rotate the beam 40 so that the rectification plates 59 of the rectification unit rows 34 and 35 are substantially horizontal. By doing so, the floating material can be captured by the rectifying plate 59.

When the turbidity of the water is detected by a turbidimeter and the turbidity becomes large, all or a part of the trap plates 44 of the lower settling unit rows 29, 30, 33 are angled, The water flow may be controlled so that the water flows upward. More specific sedimentation unit
An interferometer is attached on the trap plate 44 of 41, and the amount of suspended matter on the trap plate 44 is measured by the interferometer.When a certain amount of suspended matter is accumulated, the beam 40 is rotated by about 90 degrees. It can also be cleaned. In this case, it is possible to control the drive source by using an interface meter and a timer together.

It is also possible to use sedimentation, deodorization and biological treatment in combination, and perform sedimentation in the former stage, deodorization in the latter stage, and biological treatment in the latter stage. Each settling unit 41-43 is a settling unit row
The beams 40 may be arranged in a staggered manner on the plane so as to be shifted by half a pitch in the longitudinal direction of the beam 40 every 27 to 33. Furthermore, sedimentation units 41 to 43, deodorizing unit 136, biological treatment unit 14
0 or the like may be suspended by one, two or three suspension members 45. However, also in these cases, it is necessary to change the angle of the capturing plate 44 and the like via the suspending member 45, but the means is not limited.

In the embodiment, the trapping plate 4 is used as the purifying member.
4, the deodorizing member 135 and the biological treatment member 139, and the sedimentation units 41 to 4 provided with a large number of trap plates 44 as a purification unit.
3, the deodorizing unit 136 including the deodorizing member 135 and the biological processing unit 140 including the biological processing member 139 are illustrated respectively, but the cleaning member and the cleaning unit have a cleaning function other than these, for example, fine floating. It is needless to say that an object may be captured by charge adhesion, contact adhesion, or the like, and in that case, the same can be applied.
