Description

Inclined plate module and fast sedimentation device having the same {Lamella modules and Fast Sedimentation Device therewith}

The present invention relates to a sewage, wastewater or water treatment apparatus, and more particularly to a slope plate module and a high speed sedimentation apparatus having the same.

In general, sewage and wastewater treatment systems remove the organics and suspended solids in raw water using the principle of flocculation and sedimentation. Such water treatment devices have been widely used to purify plant wastewater, livestock wastewater, domestic sewage, and the like.

However, the conventional water treatment apparatus discharges stable treated water only when a large sedimentation area and a long flocculation time are satisfied. Therefore, when these conditions were not met, there was a tendency to rely on excessive drug administration and specialty drugs to obtain stable treated water. As a result, drug costs, sludge treatment costs, etc. have risen, resulting in problems that are uneconomical and inefficient.

In order to solve this problem, the research on the inclined plate precipitation apparatus has been actively conducted in recent years. Such inclined plate precipitation apparatus is a method of connecting the rapid reaction tank, slow flocculation tank and inclined plate settling tank in series. That is, in the rapid reaction tank, the initial aggregate is formed by combining high speed agitation through a stirrer and adding a chemical (eg, inorganic coagulant), and in a slow agitation tank, a slow agitation through an agitator and an organic polymer coagulant are added to ripen the fine plot. Do Then, in the settling tank, the matured plot sinks down as it passes through the object countercurrent sloping plate, and solid-liquid separation occurs where the supernatant is discharged through the upper weir and waterway.

However, such a conventional inclined plate precipitation apparatus requires not only a rapid reaction tank and a slow aggregation tank in addition to the precipitation tank, but also has a limitation that depends on whether the process is a microbial reaction process or a wastewater treatment process. In addition, since the performance of the swash plate sedimentation tank is sensitive to design variables and operating conditions, much design know-how was required. For example, drift occurs in the flow of raw water as the size, installation position, and installation interval of the inclined plate change, which leads to sludge generation of the inclined plate. As a result, the flow of the inclined plate is blocked, and additional load is generated in the remaining inclined plate. This eventually leads to a vicious cycle of sludge in the slanted plate, thereby closing the slanted plate and rising of the sludge.

Therefore, the present invention has been devised to solve the above problems, the first object of the present invention is to convert the fluid flow of raw water into a uniform laminar flow without turbulence and drift, so that an even distribution flow occurs in the inclined plate It is to provide an inclined plate module and a high speed precipitation apparatus having the same.

The second object of the present invention is to provide an inclined plate module and a high speed sedimentation device having the same, so that it is easy to purchase and quickly install the inclined plate module according to a desired capacity and dimensions without knowing the design or expert construction know-how in the wastewater treatment device. .

Hereinafter, with reference to the accompanying drawings to describe the embodiment of the present invention in detail.

1 is a schematic side cross-sectional view of a high speed precipitation apparatus 100 having an inclined plate module according to a first embodiment of the present invention (rotary scraper). As shown in FIG. 1, the high speed precipitation apparatus 100 includes a first, second, and third water flow guide plates 120, 122, and 124, a settling tank 140, a slope plate module 300, and a sludge discharge facility. have.

The first water flow guide plate 120 is formed at the raw water inlet 110 to direct the flow of raw water introduced through the raw water inlet 110.

The second water flow guide plate 122 is installed to be spaced apart in parallel from the first water flow guide plate 120 and has a function of directing the flow of raw water passing through the first water flow guide plate 120 upward again.

The third water flow guide plate 124 is installed to be spaced apart in parallel from the second water flow guide plate 122 and has a function of directing the flow of raw water passing through the second water flow guide plate 122 downward again. In particular, as the distance between the second and third water flow guide plates 122 and 124 is wider than the space between the first and second water flow guide plates 120 and 122, the raw water may have a slower flow. As described above, the first, second, and third water guide plates 120, 1222, and 124 are arranged in a zigzag form in order to change the flow of the introduced raw water downward, upward, and downward again.

One end side for uniform inflow into the settling tank 140 at a gentle flow rate while flowing through the first, second and third flow paths 112, 114 and 116 formed by the first and second water flow guide plates 120 and 122. The other end cross-sectional area is wider than the cross-sectional area. That is, by making the flow paths 112, 114, and 116 without connecting the pipes to the settling tank 140, dissolution between aggregates is not possible while the raw water flows into the settling tank 140, and the sedimentation tank 140 has a very fast settling effect. Will be obtained.

The sedimentation tank 140 is a portion in which floc is settled in raw water, and a scraper 134 is installed at a lower portion thereof, and an inclined plate module 300, a treated water overflow wear channel 160, and a treated water outlet 210 are disposed at an upper portion thereof. Etc. are installed.

The drive motor 130 is provided at the top of the settling tank 140, the drive shaft 132 extends vertically downward to extend to the bottom surface of the settling tank 140. Then, the scraper 134 is connected to the drive shaft 132 is configured to rotate while scratching the bottom surface of the settling tank 140. The scraper 134 has four scrapers extending radially about the sludge collection pit 150.

The sludge collection pit 150 is a place where the sludge concentrated by the scraper 150 is constantly collected. For this purpose, the bottom surface of the lower center of the settling tank 140 is recessed by a predetermined volume.

One end of the discharge pipe 180 is connected to the sludge collection pit 150, and the other end is connected to two sludge discharge pumps 182 and 184 connected in parallel. The discharge side of the sludge discharge pumps 182 and 184 is connected to the sludge storage tank 190.

The inclined plate module 300 is placed horizontally on the top of the settling tank 140, several are placed side by side according to the design specifications and capacity. The inclined plate module 300 is supported by the concrete structure (or steel structure, FRP structure, etc.) constituting the settling tank 140.

A plurality of treated water overflow wear channel 160 is installed side by side on the inclined plate module 300. It is important that the plurality of treated water overflow wear channels 160 are arranged in equally spaced intervals in parallel to each other. If they are not evenly spaced or parallel, they may cause drift or turbulence between the inclined plates.

Therefore, the treated water overflowed after passing through the inclined plate module 300 enters the treated water final water channel 200 through the treated water overflow wear channel 160, and finally through the treated water outlet 210 to the outside. Discharged. To this end, the treated water overflow wear channel 160 is connected to the final treated water channel 200, and the treated water outlet 210 is disposed below the final treated water channel 200.

2 is a plan view of the high speed precipitation apparatus shown in FIG. As shown in FIG. 2, the space formed by the outer concrete (or steel structure, FRP structure, etc.) structure of the sedimentation tank 140 and the first water flow guide plate 120 forms the first water flow 112. This first stream of water 112 has a rectangular planar formation as shown in FIG. 2.

The space formed by the first water flow guide plate 120 and the second water flow guide plate 122 forms a second water flow 114. This second stream of water 114 has a rectangular planar formation as shown in FIG.

The space formed by the second water flow guide plate 122 and the third water flow guide plate 124 forms a third water flow 116. This third stream of water 116 has a rectangular planar shape as shown in FIG. 2. As shown in FIG. 2, the third stream of water 116 has a larger area in order to slow the flow of raw water as the process proceeds.

The scraper 134 has a length such that the four scrapers 134 are perpendicular to each other about the driving motor 130 and rotate on the bottom surface. The four scrapers 134 have wings protruding from each other, and as the scraper 134 rotates, sludge at the bottom is collected at the center.

In the case of the inclined plate module 300, six are arranged side by side. In each of the inclined plate modules 300, the treated water overflow wear tank 160 is arranged in parallel at equal intervals. The treated water overflow wear tank 160 serves to flow the treated water passing through the inclined plate module 300 to the final treated water tank 200.

The treated water final channel 200 also has the same width as the settling tank 140, and the treated water outlet 210 is formed at the bottom of the center.

3 is a partially enlarged plan view of the settling tank 140 and the inclined plate module 300 of FIG. As shown in FIG. 3, the bottom surface of the settling tank 140 is approximately square, and the inclined plate module 300 has a rectangular planar shape. In addition, the inclination plate module 300 installed in the central region has a separate space for the passage of the drive shaft 132.

4 is a partial cross-sectional view taken along the line A-A in FIG. 3. As shown in Figure 4, in order to support both ends of the inclined plate module 300, the concrete structure (or the steel structure of the inclined plate module lower support 142 and the settling tank 140 protruding from the third water flow guide plate 124, FRP structure, etc.) is provided with a lower support 142 protruding inwardly. In addition, another lower support 144 supports the intermediate region of the inclined plate module 300 for more stable support. For reference, a guardrail is installed at the upper portion of the settling tank 140 for the safety of the driver or manager approach.

5A is a front view of the inclined plate module 300 according to FIGS. 1 to 4 and the present invention, and FIG. 5B is a front view of the inclined plate module 300 'according to another embodiment of the present invention, and FIG. The perspective view of the frame with the inclination plate removed in 5b. As shown in FIGS. 5A, 5B and 6, the inclined plate module 300 is a substantially rectangular rectangular parallelepiped, and each corner region is provided with a first frame 310 and a second frame 360, and appropriately supports a load. To this end, a plurality of third frames 320 are provided in a diagonal direction. In addition, the upper surface of the inclined plate module 300 is provided with about four rings 350 to facilitate installation and movement using a crane or the like.

Small slits 315 are processed at regular intervals and repeatedly on the first flame 310 so that the inclined plates 340 and 340 'may be inclined at 50 to 60 degrees. Accordingly, the inclined plates 340 and 340 'are inserted from the side surfaces of the first frame 310 and inserted into the slits 315, and then welded and fixed between the slits 315 and the inclined plates 340 and 340'. Accordingly, the rectangular inclined plates 340 and 340 'are welded and fixed with the first flame 310 at four vertex areas. In addition, when the sizes of the inclined plates 340 and 340 ′ are large, strength may be increased by attaching a separate spacer (not shown) in which a slit is formed outside the frame. The frames 310, 320, 360 are made of steel beams or corrosion resistant section steel for maintaining sufficient rigidity.

In addition, the inclined plate 340 is installed to form an inclination angle of 50 degrees to 60 degrees with respect to the first frame 310 that is horizontally installed as a large upflow separation type inclined plate.

More specifically, the inclined plate module 300 has a height of 500 mm to 2000 mm, a length of 500 mm to 8000 mm, and a width direction of 500 mm to 2000 mm. If the size is longer or larger, more design effort is required to form a uniform laminar flow.

7A is a perspective view of a bent inclined plate 340 according to one embodiment of the present invention, and FIG. 7B is a perspective view of a straight inclined plate 340 ′ according to another embodiment of the present invention. As shown in FIG. 7A, the intermediate region of the bent ramp 340 is bent by a predetermined angle (eg, 30 to 60 degrees) in the horizontal direction of the treated water flow. Such bending of the intermediate region helps to distribute the flow of treated water evenly without drift, and can increase the effective area of the inclined plate. Therefore, the processing capacity per unit time can be increased. In other words, it is used to discharge the treated water at a higher speed. In the inclined plate 340, a plurality of valleys 344 are recessed from the flat portion 342 along the flow of the treated water. The valleys 344 maintain equal intervals and are formed in parallel to each other.

The flat portion 342 and the valley portion 344 form an inclined surface 346. Therefore, the overall cross-sectional shape of the valley part 344 becomes a trapezoidal shape (or foot-shaped cross-sectional shape) with one side open. As a result, the treated water passing between the inclined plates forms a parallel flow path in which the flow is not broken.

In FIG. 7B, the inclined plate 340 ′ having the same cross-sectional shape as that of FIG. 7A is disclosed. The difference is that the inclined plate 340 ′ is not curved in the middle region. In this case, the flow of the treated water can be used at a lower speed.

Hereinafter will be described the operation of the inclined plate module having a configuration as described above and a high speed precipitation apparatus having the same.

First, the inclined plate module 300 is installed in the settling tank 140. That is, the plurality of inclined plate module 300 is lifted through the ring 350 and then placed side by side on the inclined plate module lower support 142. Next, the treatment water overflow wear channel 160 is installed and completed.

The raw water introduced through the raw water inlet 110 is led downward by the first water flow guide plate 120, and then upwardly led by the second water flow guide plate 122. Then, the area is enlarged by the third water flow guide plate 124, and the flow velocity is slowed. Thus, the raw water slowly forms a laminar flow and enters downward toward the bottom region of the settling tank 140.

In the settling tank 140, the raw water in which the aggregate and the waste water are mixed passes through the inclined plate module 300. At this time, the aggregates settle, and the wastewater becomes treated water while passing through the inclined plate. Since the inclined plate 340 increases the effective settling area, separation of the solid (sludge) and the liquid (treated water) occurs effectively. Thus, a clear supernatant can be obtained even with a small settling area.

The settling aggregates build up as sludge on the bottom. Then, the driving motor 130 rotates to rotate the drive shaft 132 and the scraper 134. Accordingly, the sludge accumulated on the floor is collected at the center by the scraper 134 and concentrated on the sludge collecting pit 150.

Then, when the sludge discharge pumps 182 and 184 are driven, the sludge collected through the discharge pipe 180 is transferred to the sludge storage tank 190 to be reduced in a separate concentration and dehydration process.

On the other hand, the treated water passing through the inclined plate module 300 is collected by the treated water overflow wear channel 160 to the treated water final channel 200. Then, it is transferred to a separate place through the treated water outlet 210. Through this process, the solid (sludge) liquid (treated water) is separated from the raw water.

8 is a schematic cross-sectional view of a high speed precipitation apparatus having an inclined plate module according to a second embodiment of the present invention (infinite guided scraper). As shown in Figure 8, instead of the rotary scraper, an endless scraper 450 was adopted. As such, when the infinite rubbing scraper is adopted, the use of the site is increased because a long rectangular high-speed sedimentation basin can be formed.

Infinite guided scraper 450 is operated in the settling tank 140 by one driving pulley 420 and at least two driven pulleys (430, 440). In addition, a plurality of scraper protrusions 460 are formed on the surface of the infinite scourer-type scraper 450 to collect the sludge more effectively. The scraper protrusion 460 serves to move the sludge in one direction while scratching the bottom surface.

The driving device 400 is a motor installed outside the settling tank 140 and transmits rotational force to the driving pulley 420 through a chain, a belt, a gear, and the like. Such a configuration of the driving device and the like is easy for those skilled in the art, so detailed illustration and description will be omitted.

In addition, the sludge collection pit 150 is formed in one side configuration of the settling tank 140. This is to effectively collect the sludge against the endless rubbing type scraper 450 that linearly moves in one direction.

Other configurations or operations of the second embodiment are similar to those of the first embodiment described above, and thus description thereof will be omitted.

Specific parameters of the inclined plate module and the high speed precipitation apparatus having the same according to the present invention are as follows. That is, the mean flow velocity of the settling tank 140 is 0.1 m / sec or less, the residence time is 20-50 minutes, the surface load of the settling tank is 4-15 m / hr, the surface area load of the inclined plate is 6-20 m / hr, The interval of the inclined plate is 50-100mm, the vertical height of the inclined plate is 1.0 ~ 2.0 m, the residence time in the inclined plate is 5 minutes or more, the bending angle of the inclined plate is 60 degrees, and the circumferential speed of the scraper is 2-4m / min.

And, Figure 9 is a graph of the fluid flow and computational hydrodynamic simulation results in the high speed sedimentation apparatus according to the present invention. In FIG. 9, the shapes of the third channel 116, the settling tank 140, and the inclined plate were determined, and then a simulation of flowing raw water was performed. The purpose of these simulations is to determine if the drift occurs at the bottom of the sloping plate or where and if so to what extent.

For reference, in order to increase the performance of the solid-liquid separation in the inclined plate settling tank it is most important to guide the flow of the fluid to a constant laminar flow to make the constant upward flow rate. If drift or turbulence occurs in the flow and the flow velocity is not constant, floc loss or sludge blockage may occur and sludge settling efficiency is reduced.

As can be seen in Figure 9, it can be seen that only the laminar flow of a uniform flow is formed in the lower portion of the inclined plate without drift or turbulence. This means that sludge does not occur between the inclined plates, and eventually, it can be expected that the inclined plates are not blocked by the sludge.

In another modified embodiment of the precipitation tank 140 of the present invention, the lower portion of the precipitation tank 140 may be manufactured in a quadrangular pyramid or a cone shape, in which case it is not necessary to install a scraper.

In addition, as another embodiment of the present invention, a straight inclined plate that is not bent at the center region may be installed at an angle. In this case, the flow of the treated water can be used at a lower speed.

According to the inclined plate module of the present invention and a high speed precipitation apparatus having the same, the fluid flow of raw water is converted into a uniform laminar flow without turbulence and drift, and an even distribution flow occurs in the inclined plate. This prevents sludge in the slant plate due to drift in the flow of raw water. For this reason, the flow of the inclined plate is smooth even without long-term operation.

In addition, there is an efficiency and economical efficiency in that it is easy to purchase and quickly install the inclined plate module according to the desired capacity and dimensions without high design know-how or expert construction know-how in the sewage treatment system.

In addition, even if there is a wide narrow in the sedimentation tank area according to the design location, use and capacity, the construction can be completed only by installing the inclined plate module according to the number of the horizontal and the interval, it is convenient for construction and construction method selection. This will lead to the expansion of the application of wastewater treatment system using sloped plates and the continuous research and development in related fields.

And sewage and sewage inlet stages, final sedimentation stages after biological reactors, and sedimentation basins requiring solid-liquid separation (sludge and treated water) for purification and water treatment, It has the advantage of compact design and construction.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Therefore, the scope of the attached utility model registration request will include such modifications and variations that fall within the spirit of the present invention.
