Field of the Invention The present invention relates to a float-type scum and floating material removal device, a float-type scum and a floating material processing device, and a water purification system for a reservoir using the float-type scum and floating material removal device. pond using the same}

The present invention relates to a float type scum and floating material removing device and a water quality purification system for a reservoir using the float type scum and floating material removal device. More particularly, the present invention relates to a float type scum and floating material removal device that is installed in a reservoir such as a lake or a pond, Float type scum and floating material removing device, and a water quality purification system of a reservoir using the same.

As the population grows and the industry develops, a lot of pollutants are also emitted. Particularly, in the case of water pollution, in addition to the primary damage caused by the introduction of various pollutants into the water and the deterioration of the water quality itself, the secondary damage by destroying the underwater ecosystem by blocking the light and oxygen, Which causes a series of damage. To prevent this, agricultural wastewater, industrial wastewater, etc., including domestic sewage flowing into rivers and streams, are discharged through water treatment processes.

In general, the water treatment process is divided into physical and chemical processes. The physical process is to remove the contaminants primarily through floating and filtration processes. The initial state of contaminated water contains bubbles and various suspended substances. Unless these substances are effectively removed, the secondary treatment process or contaminated water will be very burdensome when passing through the filter medium or filtration membrane, and the filter medium or filtration membrane will be easily damaged . Therefore, it is very important to remove floating substances or bubbles from the polluted water in the initial state.

In order to remove such scum and suspended matter, it has been proposed to remove scum and suspended matter using a skimmer or the like. Regarding this, in Japanese Patent No. 10-0958679, a turntable for supporting a scraper and a turntable for supporting a skimmer for removing a scum are separately constructed in order to remove sludge of a cylindrical sewage treatment apparatus, Thereby removing sludge and scum.

  However, the apparatus for removing scum and suspended matters using a skimmer or the like not only has a low efficiency of removing scum as the skimmer moves on the surface of the water, disturbing the contaminated water and mixing some scum or suspended matter into the water, There is a problem that the step of the process is increased. Further, there is a problem in that it is inconvenient to dispose of the scum and the suspended material collected, such as scum scraping or washing with water, in order to remove scum and suspended matter collected in a skimmer or the like.

On the other hand, various pollutants flow into the water in reservoirs such as lakes and ponds, and algae are formed due to eutrophication to float in the form of scum and suspended matter. Such scum and floating substances, It is required to develop a scum and a floating material removal device that collects and removes a scum and a floating material, and also to develop a water quality purification system that cleans water quality of the reservoir which is deteriorated by scum and suspended matter.

The float-type scum and floating material removal apparatus 100 according to the embodiment of the present invention configured as described above floats on reservoir and is fixed or installed at a predetermined place or installed to be movable. When the driving motor 123 of the water inflow unit 120 is operated in the state of being installed in the reservoir, the rotary vane 122 rotates, and the contaminated water containing the scum and the floating substance floating on the water surface in the reservoir 110 To the space S of the recording medium. At this time, the trapping membrane 112 separates the contaminated water in the space S from the water in the reservoir, so that the scum and the floating substance can be effectively moved into the space S.

The scum and the suspended material of the contaminated water moved to the space S are mixed into the water due to the disturbance of the contaminated water due to the rotation of the rotary vane 122. The scum and the floating material mixed in the water are discharged to the float electrolytic floating module 130). ≪ / RTI > That is, fine hydrogen gas bubbles are generated in the cathode of the electrode plate 131 of the float electrolytic floating module 130, and air bubbles adhere to the scum and the floating substance, so that they float again. The scum and the floating material B floating on the water surface are moved toward the collection module 140 according to the flow of the contaminated water due to the operation of the water inflow unit 120. The diving depth of the electrode plate 131 of the float electrolytic floating module 130 is adjusted by moving the supporting frame 133 provided with the electrode plate 131 in the up and down direction by operating the depth adjusting unit 132, To the appropriate height.

When the slide 142 of the collection module 140 is opened, the scum and the floating material B floating on the water surface inside the space S toward the collection module 140 are collected inside the collection module 140.

If a certain amount of scum and suspended material is present in the collection module 140, the drive body 143 is driven to close the slide 142 of the collection module 140 and drive the pump 150 to mix the mixture of scum and suspended matter (See FIG. 6) installed on the ground, temporarily stored in the float storage tank 160 as shown in FIG. 4, or transferred or dehydrated to the treatment plant for secondary treatment Transfer to the dehydration field. Further, in addition to moving the mixture of scum and suspended material to the ground, the float-shaped scum and the suspended material treatment apparatus separately installed in the lake can be moved to the treatment facility. The float-type scum and floating material processing apparatus will be described later.

FIG. 5 is a schematic block diagram showing a water quality purification system of a reservoir using a float-type scum and floating material removal apparatus according to an embodiment of the present invention. FIG. 6 is a block diagram of a float- FIG. 7 is a block diagram showing a scum and suspended solids treatment apparatus in FIG. 6. FIG. The water purification system 10 of the reservoir includes a float type scum and floating material removal device 100, a mixture storage tank 200, a scum and suspended matter processing device 300, a dewatering device 400 ).

The float-type scum and floating material removal device 100 is constructed as shown in Figs. 1 to 4, and is floated on the reservoir P. Fig.

The mixture storage tank 200 is a storage tank or a storage tank for temporarily storing a mixture of scum and suspended matter collected in the float type scum and floating material removal apparatus 100. [ The mixture stored in the mixture storage tank 200 is transferred to the scum and suspended matter processing apparatus 300 through the pump 201 and the pipeline 202.

The scum and suspended solids treatment apparatus 300 is installed on the ground and separates the mixed mixture into treated water and sludge and discharges the treated water to the reservoir. The apparatus includes an inflow tank 310, a floating tank 320, An elimination module 330, a float electrolytic floating module 340, and a treatment water tank 350.

In the inflow bath 310, a mixture of scum and suspended solids is introduced into the mixture storage tank 200 and separated from the floating tank 320 by two partition walls 301. The mixture introduced into the inflow bath 310 is in communication with the float bath 320 through the inflow channel between the partitions 301.

The float tank 320 floats the scum and floating material mixed in the water in the mixture to the water surface, and has a floating device 321 and a guide wall 322. The floating device 321 floats the scum and the floating material B in the floating tank 320. The floatation device 321 is located at the lower end of the inflow channel for introducing the mixture into the floating tank 320. Generally, the floatation device 321 generates minute bubbles by using a partial pressure which is a difference in pressure between gas and liquid, ). Thus, the scum and the floating material B are positioned on the upper surface of the floating tank 320 while the mixture is moving in the floating tank 320.

Inside the floating tank 320, a guide wall 322 having a height lower than the water surface height is formed at a position apart from the partition wall 301 formed with the inflow channel. The guide wall 322 is provided to prevent the scum and the floating material B from spreading into the water in the floating tank 320 while the floating material B floats, Float up. Beyond the guide wall 322, the contaminated water in the lower layer of the scum and the floating material B is surplus. The scum and the floating material B which have flown into the floating tank 320 and floated by the floating device 321 move in the flow direction of the mixture which is floated on the water surface. The contaminated water flowing into one side of the floating tank 320 moves within the floating tank 320 and is discharged through the connection water channel 323 located at the other lower side of the floating tank 1100.

The removal module 330 collects floating scum and floating material B on the water surface of the contaminated water (mixture). As the mixture flows into the floating tank 320, the level of the floating tank 320 increases. The removal module 330 opens the removal module body 331 (see FIG. 8) according to the level of the mixture in the floating tank 320. The scum and the floating material B flow into the removal module main body 331 as the removal module main body 331 is opened. The scum and the floating material B are collected in the removal module 330 by periodically opening the removal module main body 331. [ The sludge of the scum and floating material B collected in the removal module 330 is stored in the scum and floating material storage tank (not shown) or dehydrated in the dehydration device 400.

The floatation electrolytic floating module 340 is installed on the lower side of the removal module 330. The scum and the floating material B floating by the opening and closing operation of the removal module 330 can be mixed again into the contaminated water at the lower side. The floatation electrolytic floating module 340 generates minute bubbles to float the floating scum and floating material B near the removal module 330 back to the surface of the water. The scum and the floating material B mixed into the contaminated water can be re-floated by the disturbance of the contaminated water by the opening and closing operation of the removal module 330, thereby further enhancing the removal efficiency of the scum and the suspended substances.

The treated water tank 350 receives the contaminated water from which the scum and suspended substances have been removed from the floating tank 320. The scum and floating material B in the floating tank 320 are removed and the contaminated water moving to the treatment water tank 350 is referred to as a treatment water. The treated water flowing into the treated water tank 350 is discharged to the reservoir P. The treated water may be filtered or discharged through a post-treatment process. A level measuring module 351 for measuring the level of the contaminated water is installed on the side wall of the treatment water tank 350. The elimination module 330 operates according to the water level value measured by the water level measurement module 351. The contaminated water or treated water continuously flows in and out of the floating tank 320 and the treated water tank 350 and the water level continuously changes because the scum and the floating material B and the partially contaminated water are removed by the removal module 330 . Since the floating tank 320 and the treatment water tank 350 are connected to each other through the connection waterway 323, the water level in the floating tank 320 and the treatment water tank 350 And become equilibrium. The treated water in the treatment water tank 350 is discharged through an outlet located on the opposite side of the connection waterway 323. The contaminated water or treated water is continuously flowed into and discharged from the floating tank 320 and the treated water tank 350. The amount of treated water discharged from the treated water tank 350 may change temporarily depending on the change of the water level, Emissions are constant.

The upper part of the inflow tank 310, the floating tank 320 and the treatment water tank 350 can be opened, and when the upper part is opened, the state of scum and floating material can be visually confirmed easily.

The dewatering device 400 is a device for dewatering the scum and the sludge of the suspended matter B collected in the removal module 330 of the scum and suspended matter treatment device 300. The dehydrated cake in the dehydrator 400 is buried or recycled, and the dehydrated filtrate is returned to the mixture storage tank 200.

FIG. 8 is an exploded perspective view showing the removal module in the scum and suspended material processing apparatus of FIG. 7, and FIG. 9 is an operational state diagram of the removal module in the scum and suspended material processing apparatus of FIG. As shown, the removal module 330 includes a removal module body 331, a removal slide 332, a slide arm 333, and a hydraulic motor 334. The removal module main body 331 is in the form of a container with an open top. In the inside of the removal module main body 331, collected scum and floating material B are accommodated. The lower part of the removal module main body 331 is inclined toward the bottom surface. By forming the lower part of the removal module main body 331 obliquely, the collected scum and the floating material B are easily discharged through the discharge port 335 located at the lower part. A first removal inlet port 331a is formed on the front surface of the removal module main body 331. [ On the inner surface of the removal module main body 331, a guide portion 331b is formed.

The removal slider 332 is guided to the guide portion 331b formed on the inner surface of the removal module main body 331 to move up and down. A second removal inlet 332a is formed at the top of the removal slider 332. The second removal inlet 332a is formed to have the same width and the same width as the first removal inlet 331a. The scum and the floating material B are moved into the removal module main body 331 through the opening in which the first and second removal inlets 331a and 332a are formed by the movement of the removal slider 332. [

The slide arm 333 is connected to the top of the removal slide 332. The slide arm 333 is connected to the removal slide 332 through at least one support and supports the removal slide 332.

The hydraulic electric motor 334 is connected to the slide arm 333 and moves the slide arm 333 up and down by the hydraulic pressure. As the slide arm 333 moves up and down, the removal slide 332 also moves up and down. Since the removal slide 332 has to move a certain distance in the removal module main body 331, the slide arm 333 can be set to move only as far as the movement distance. For example, the control unit can control the rotating direction of the hydraulic electric motor 334. [ A sensor is provided inside the removal module main body 331 so that when the lower side of the removal slide 332 contacts the sensor, the control unit can control the rotation direction of the hydraulic motor 334 to be opposite. In another embodiment, a sensor may be installed in the hydraulic electric motor 334 so that the hydraulic electric motor 334 moves only a certain distance. In this embodiment, a hydraulic motor is used to move the slide arm 333, but the present invention is not limited thereto, and a motor may be used.

Next, the operation of the removal module 330 will be described with reference to Figs. 7 to 9. Fig. The removal slide 332 is inserted into the removal module main body 331 while being inserted into the guide portion 331b of the removal module main body 331 when the contaminated water (mixture) As shown in FIG. In this case, the first removal inlet 331a of the removal module main body 331 is brought into contact with the lower portion of the removal slide 332, and is shut off by the lower portion of the removal slide 332. The mixture (contaminated water, scum and suspended matter) is blocked by the removal slide 332 and can not enter the removal module body 331.

The hydraulic motor 334 moves the slide arm 333 downward so that the first removing inlet 331a and the second removing inlet 332a are communicated with each other so that the contaminated water level in the floating tank 320 becomes a certain level or more do. The scum and the floating substance B are first introduced into the first and second removal inlet openings 331a and 332a and the opening by the communication of the first and second removal inlet openings 331a and 332a reaches the height of the contaminated water When opened, contaminated water is passed through the first and second removal inlets 331a and 332a. The contaminated water flows into the first and second removal inlet openings 331a and 332a and the scum and the floating material B located thereon are introduced into the first and second removal inlet openings 331a and 332a at a high speed.

9A, when the first removal inlet port 331a is closed by the removal slide 332, the contaminated water, scum, and suspended substance B do not flow into the removal module main body 331 And waits in a state of being stacked in front of the first removal inlet 331a. 9 (b), when the removal slide 332 moves downward and a part of the first and second removal inlet openings 331a and 332a is opened, 2 removal inlets 331a, 331b, so that the contaminated water does not flow into the openings, and only the scum and the suspended material B flow in. At this time, since the scum and the suspended material (B) have low fluidity, they can not move fast, only a part of the scum and the suspended material move, and most of the scum and the suspended material continue to the removal module according to the flow of the contaminated water And then waits at the closed removal inlet. Since the scum and the suspended substance moving according to the flow of the polluted water are accumulated in front of the removal inlet, the scum and the suspended substance accumulate thickly toward the removal inlet.

9 (c), when the removal slide 332 completely moves downward and the entire openings by the first and second removal inlet openings 331a and 332a are opened, The scum and the floating substance B floating on the contaminated water surface together with some contaminated water are passed to the first and second removal inlets 331a and 332a. At this time, it is preferable that the height of the lower ends of the first and second removal inlet openings 331a and 332a is slightly lower than the water level of the contaminated water. As the first and second removal inlet openings 331a and 332a are opened, And moves into the removal module main body 331 together with the scum and the floating material. In other words, the height of the water level for moving the removal slide 332 to open the first and second removal inlet openings 331a and 332a may be set according to the place and the situation where the scum and the suspended solids processing apparatus 300 are installed , And slightly higher than the lower end of the first removal inlet 331a. This is because, when the first and second removal inlet openings 331a and 332a are completely opened, a small amount of contaminated water is introduced so that the efficiency of removing scum and suspended substances can be increased.

FIG. 10 is a perspective view showing the float electrolytic floating module in the scum and suspended matter treating apparatus of FIG. 7, and FIG. 11 is an operational state view of the float electrolytic floating module in the scum and suspended matter treating apparatus of FIG. As shown in FIG. 10, the float electrolytic floating module 340 includes a plurality of anode plates 341 and cathode plates 342. The positive and negative electrode plates 341 and 342 are formed of a carbon material and are in the form of a rectangular plate. The electrode plates 341 and 342 of the carbon electrode have a pair of the positive electrode and the negative electrode, and the positive electrode and the negative electrode are alternately arranged.

When power is applied to the floatation electrolytic floating module 340, water is decomposed and minute hydrogen gas is generated at the (-) electrode. The reactions occurring at the positive electrode and the negative electrode of the electrode plates 341 and 342 of the carbon electrode are as follows.

Cathode: 2e ^- + 2H ₂ O ^- > H ₂ (g) + 2OH ^-

Anode: 2H ₂ O? O ₂ (g) + 4H ⁺ + 4e ^-

When minute hydrogen bubbles are generated in the cathode of the carbon electrode, oxygen generated in the anode of the carbon electrode contributes to reduction of oxidation of the organic matter and the like. On the other hand, in the vicinity of the removal module 330, B). The surface area of the electrode plates 341 and 342 can be increased or the gap between the electrode plates 341 and 342 can be reduced in order to increase the floating efficiency by generating a large amount of minute bubbles. The hydrogen gas is generated at the cathode of the carbon electrode plates 341 and 342 so that the number of the cathode plates 342 is made larger than the number of the anode plates 342 and the efficiency of bubble generation can be increased.

In the case of using a carbon electrode, a relatively simple process can reduce the scale of the negative electrode and the hydrogen polarization phenomenon, and the power consumption can be reduced. Further, since the carbon electrode does not participate in the electrolysis itself during the electrolysis, metal ions are not generated and the water quality is not changed as compared with the case where the metal electrode is used.

In the electrolytic reaction, the amount of bubbles is proportional to the amount of applied current, and the size of the particles of the generated bubbles depends on the applied voltage. When the applied voltage is low, the particle size of the generated bubbles is small, while the size of the bubble particles generated at the high applied voltage is large. If the size of generated bubbles is too small or too large, the floatation efficiency of scum and suspended matter may be decreased. Therefore, the average amount of scum and floating material mixed through the experiment should be calculated and the optimum voltage should be applied.

As shown in FIG. 11, the float electrolytic floating module 340 operates at the lower end of the elimination module 330. 9 and 11, the floatation electrolytic floating module 340 does not always operate, but operates when the first removal inlet 331a (see FIG. 9) of the removal module 330 is closed do. That is, the float electrolytic floating module 340 is stopped while the removal slide 332 is falling (opening the first and second removal inlets), and the removal slider 332 is raised (the first and second removal inlets Closed).

When the first and second removal inlets 331a and 332a are opened, the scum and the floating substance B floating on the contaminated water flow into the first and second removal inlets 331a and 332a together, When the removal slide 332 is moved upward and the first removal inlet 331a is closed, the flow of the contaminated water is blocked and the contaminated water is disturbed by inertia. When the contaminated water near the removal module main body 331 is disturbed, the scum and the floating material B are mixed again into the contaminated water. In this case, scum and suspended solids are inevitably contained in the contaminated water moving to the treatment water tank 350. However, if the floatation electrolytic floating module 340 is operated to generate the minute bubbles C while the first and second removal inlets 331a and 332a are closed, the scum and the floating material B can be floated again . Accordingly, the influence of the disturbance due to the opening and closing of the removal inlets 331a and 332a can be minimized, and the scum and the suspended substance B can be excluded from the contaminated water moving to the treatment water tank 350 as much as possible.

12 is a view showing the level of the flotation tank and the treatment tank in the scum and suspended solids treatment apparatus of FIG. 9 and 12, in the removal module 330, the first and second removal inlet openings 331a and 332a are opened while being communicated when the water level becomes a certain level. That is, the removal slide 332 is determined to move according to the measured water level. However, since the scum and the floating material B float above the floating tank 320, it is difficult to measure the accurate water level. Therefore, the water level in the treatment water tank 350 is measured for accurate water level measurement. The floating tank 320 and the treatment water tank 350 are connected to each other by the connection water channel 323 and reach a balance with a slight time difference as the water level in the floating tank 320 changes. Accordingly, it is assumed that the floating tank 320 and the treatment water tank 350 have the same water level.

The water level of the flotation tank and the treated water tank temporarily changes when the scum and floating substances and the partially contaminated water are removed as the removal module 330 operates and the contaminated water is moved to the treated water tank 350 through the connection water path 323 . The treated water in the treatment water tank 350 does not interrupt the discharge although the discharge amount can be temporarily reduced since the contaminated water continuously flows into the floating tank 320 and is discharged through the discharge port of the treatment water tank 350.

At this time, the water level is measured by a water level measurement module 351 located on one side of the treatment water tank 350. When the water level reaches a certain level, the removal slide 332 of the removal module 330 is moved to allow the scum and the floating substance B to flow into the removal module 330. When the water level in the floating tank 320 is lowered due to the suction of the scum and the floating material B and a part of the contaminated water, the water level in the treatment water tank 350 is also lowered. When the contaminated water (mixture) including the scum and the floating material B flows into the floatation tank 320, the water level in the floatation tank 320 increases and the contaminated water moves through the connected waterway 323, So that the water level in the treatment water tank 350 also increases. As the contaminated water flows into the floating tank 320, the treated water is continuously discharged to the discharge port of the treated water tank 350 and the contaminated water moves between the floating tank 320 and the treated water tank 350 through the connected water channel 323 The floating tank 320, and the treatment water tank 350 are balanced. The removal slide 332 can be set to move when the level of the processing water tank 350 is slightly higher than the lower ends of the first and second removal inlets 331a and 332a. The treated water in the treated water tank 350 is discharged to the reservoir P. [

By this repetitive operation, the scum and the suspended material B are collected in the removal module 330. The scum and the suspended material B collected in the removal module 330 are discharged to the outside when they are a certain amount. The lower portion of the removal module main body 331 is inclined so that the scum and the suspended material can easily move downward, and thus the discharge module can be easily discharged to the outside. The scum and the suspended material B may be discharged to the outside by using a sensor located inside the removal module main body 331 to determine the discharge timing by the control unit or to discharge it at a predetermined time. The scum discharged from the discharge port and the sludge of the floating material B are stored in the scum and floating material storage tank (not shown) or dehydrated in the dewatering device 400 as shown in FIG.

The scum and the sludge of the suspended material B are dehydrated by the dewatering device 400, but a part of the sludge of the scum and the suspended material B may be sent to the sludge reduction device (not shown) and treated. A part of the sludge of the scum and the suspended material (B) may be put into the microorganism culture tank and filtered through the submerged membrane realized by negative pressure to discharge the treated water to the reservoir.

Meanwhile, in the water purification system of the reservoir using the float type scum and floating material removal apparatus of the present embodiment, the system of the mixture storage tank 200, the scum and suspended matter processing apparatus 300 and the dewatering apparatus 400 is installed on the ground However, in another embodiment, the mixture storage tank 200, the scum and suspended solids processing unit 300, and the dewatering unit 400 may be installed in a barge or the like in the reservoir P to purify the water quality of the reservoir .

The mixture storage tank 200, the scum and suspended solids processing unit 300 and the dewatering unit 400 are installed in the reservoir P integrally with the scum and suspended solids removal unit 100 to adjust the quality of the reservoir Or may be configured as a system to purify.

When the mixture storage tank 200 and the scum and suspended solids treatment apparatus 300 are installed in the lake, the collected scum and suspended solids can be collected and treated immediately, and float-type scum and suspended solids removal apparatus 100).

FIG. 13 is a view showing a float-type scum and suspended matter processing apparatus in a float-type scum removing system according to an embodiment of the present invention, and FIG. 14 is a block diagram of a float- 15 is a view showing a float type scum and floating material removing apparatus, a float type scum, and a floating material processing apparatus in the float type scum removing system according to the embodiment of the present invention, 16 is a view showing that a plurality of float type scum and suspended solids processing apparatuses are installed in the float type scum and floating material removal system according to the embodiment of the present invention, In a material removal system, a float-type scum and floating material removal device, a float-type scum, And the suspended material processing device are integrally formed.

As shown in FIG. 13, the float-type scum and the mixture of the flocculant and the scum collected primarily in the floating-matter removal apparatus 100 are moved to the float-type scum and suspended matter processing apparatus 500 floated in the lake. The float-type scum and suspended matter processing apparatus 500 includes a float 510, a scum and a suspended material storage tank 520, a scum, and a suspended material processing unit 530.

As shown in Fig. 13, the float-type scum and suspended matter processing apparatus 500 is floated on the reservoir by the float 510. As shown in Fig. The float 510 is made up of a floating body, and a scum and floating material storage tank 520, a scum and a suspended material processing unit 530 are installed therein. A guardrail 512 may be provided around the float 510 for safety purposes.

The scum and suspended solids storage vessel 520 is installed on the float 510. In the scum and suspended material storage tank 520, a mixture of scum and suspended material moved from the float-shaped scum and floating material removal apparatus 300 is stored. The float-type scum and suspended solids removal device 300 roughly collects scum and suspended substances in water and contains a large amount of polluted water other than scum and suspended substances. The float-type scum and suspended solids treatment apparatus 500 can treat such a mixture of scum and suspended matter directly in the reservoir without moving it to the ground. The mixture of scum and suspended material stored in the scum and suspended-material reservoir 520 is transferred to the scum and suspended material processing unit 530 by the pump.

On the other hand, the float 510 floating on the water is provided with a fixing device so that the scum and the floating material storage tank 520 are firmly fixed on the float 510 because the float 510 floats due to the water flow, wind or the like, . In another embodiment, a damper may be additionally provided between the float 510 and the scum and floating material storage tank 520 to suppress vibration.

The scum and suspended solids treatment unit 530 more precisely removes the scum and the suspended material B from the mixture of scum and suspended matter collected first and separates it into treated water and sludge and the treated water is discharged again into the reservoir do. 14, the construction of the scum and suspended solids processing unit 530 in the float-type scum and suspended solids processing apparatus 500 is similar to that of the ground-mounted scum and suspended solids processing apparatus 300, The float-type scum and the apparatus for treating the float material disposed in the floating-matter processing apparatus 500 to distinguish the float-type and floating-matter processing apparatus 300 from each other are called a scum and suspended matter processing unit 530.

Specifically, the scum and suspended matter processing unit 530 is fixed to the float 510. The scum and suspended material processing unit 530 is connected to the scum and floating material storage tank 520 via a pipe and a pump is connected to the scum and floating material storage unit 520 through a pump for separating the scum and suspended material from the scum and suspended material, Unit 530. < / RTI > The scum and suspended matter processing unit 530 includes an inflow bath 531, a float bath 532, a removal module 533, an electrolytic floating module 534, and a treatment bath 535. In the inflow bath 531, a mixture of scum and suspended solids is introduced from the scum and suspended solids storage tank 520. The inflow bath 531 is separated from the floating tank 532 by two partition walls 531a. The mixture introduced into the inflow bath 531 is communicated with the float bath 532 through the inflow channel between the partition 531a.

Floating tank 532 floats the scum mixed with water in the mixture and floating material (B) to the surface of water. A floating device 532a and a guide wall 532b are provided in the floating tank 532 near the entrance of the mixture of scum and suspended matter. The floating device 532a floats the scum and the floating material B in the floating tank 532. [ The floatation device 532a is located at the lower end of the inflow channel into which the mixture of scum and suspended matter is introduced into the floatation vessel 532 and the scum and suspended matter B is floated by the floatation device 532a It floats on the upper water surface and moves.

Inside the floating tank 532, a guide wall 532b having a height lower than the water surface height is formed at a position spaced apart from the partition 531a on which the inflow water channel is formed. The scum and the floating material B float up to the surface of the water without spreading inside the floating tank 532 by the guide wall 532b. The scum and the contaminated water in the lower layer of the floating material B pass over the guide wall 532b. The contaminated water moves through the floating tank 532 and flows through the connecting water channel 532c located at the other lower end of the floating tank 532. The scum and the floating material B flow in the flow direction of the mixture flowing on the water surface .

The removal module 533 collects floating scum and floating material B on the water surface of the contaminated water (mixture). The level of the floating tank 532 increases as the mixture flows into the floating tank 532 and the removal module 533 is opened and closed according to the level of the floating tank 532 to collect the scum and the floating material B. The opening and closing operations of the removal module 533 are the same as those described in Figs. As the removal module 533 is opened, the scum and the floating substance B are introduced into the removal module 533. The scum and floating material B are collected in the removal module 533 by periodically opening the removal module 533. The sludge of scum and floating material B collected in the removal module 533 is stored in a sludge tank (not shown) or dehydrated in a dehydration device (not shown). The sludge tank and dewatering device may be provided on the float 510. When the sludge tank and the dewatering device are provided on the ground, the float 510 may be moved to water variable and the scum and floating material B may be moved to store and process.

On the other hand, the scum and the floating material that have been floated due to the disturbance of the contaminated water during the opening and closing operation of the removal module 533 may be mixed into the water. The electrolytic floating module 534 is installed below the removal module 533 to float floating scum and floating material B around the removal module 533. The detailed operation of the electrolytic floating module 534 is the same as that described with reference to Figs. 10 and 11, and therefore will not be described.

In the treatment tank 535, the contaminated water from which the scum and the suspended substance B have been removed is introduced into the floating tank 532. The contaminated water from which the scum and the floating material B are removed in the floating tank 532 and moves to the treatment water tank 535 is referred to as a treatment water. The treated water flowing into the treated water tank 535 may be immediately discharged to the reservoir P or may be filtered and discharged through a post-treatment process. A level measuring module 535a for measuring the level of the contaminated water is installed on the sidewall of the treated water tank 535 so that the elimination module 533 is operated according to the measured level value.

The float 510 is designed to withstand the weight of the scum and floating material storage tank 520 and the scum and suspended material processing unit 530 installed thereon and is used to control the float 510, A damper for suppressing vibration may additionally be provided between the floating material storage tank 520, the scum and the suspended material processing unit 530.

The float-type scum and suspended matter processing apparatus 500 can move independently within the lake. The float-type scum and suspended solids treatment device 500 independently move within the slope to receive a mixture of scum and suspended solids from the float-type scum and suspended solids removal device 100, as shown in FIG.

The float-type scum and suspended solids treatment apparatus 500 may be designed in various sizes depending on the size of the installed faucet. The float-type scum and the suspended solids removal apparatus 100 move according to the position of the float- Lt; / RTI > As shown in FIG. 16, when the size of the appeal is large, a plurality of float-type scum and floating material processing apparatuses 500 are installed, and the float-type scum and scum collected from the floating material removal apparatus 100 It is possible to remove the scum and the suspended substances by receiving the mixture of the suspended substances. When a plurality of float-type scum and suspended matter processing apparatuses 500 are used, scum and suspended matter in a lake can be efficiently removed at a high speed.

On the other hand, in another embodiment, as shown in Fig. 17, the float type scum and floating material removal device, the float type scum, and the floating material treatment device may be integrated. In this case, the scum and the suspended material B primarily collected in the float-type scum and floating material removing apparatus may be separately stored in the storage tank, or may be moved to the scum and suspended material processing unit and processed.

According to the float-type scum and floating material removing apparatus of the present invention, scum and floating material are prevented from being mixed into water while scum and floating material are removed from the reservoir, Can be effectively collected and removed. In addition, the water quality purification system of the reservoir effectively treats the scum and suspended matter collected and removed through the float-type scum and floating material removal device through the scum and floating material treatment device, discharges the purified treated water to the reservoir, Water quality can be purified. At this time, the scum and suspended solids treatment apparatus minimizes the disturbance of the contaminated water during the removal, and can remove the scum and the floating substance with high efficiency.
