Description

[0002] Wastewater and rainwater treatment systems in the building [0003]

The present invention relates to a sewage and rainwater treatment system.

In general, building smokestacks and rainwater contain a small amount of organic substances, surfactants derived from soaps, detergents, etc., inorganic nutrients, and oil, but the amounts thereof are small, so that sufficient amount of organic The material is not included and the efficient treatment is not performed.

Accordingly, various treatment methods such as a separation membrane (MBR) method, an activated carbon adsorption method, and a high-grade oxidation method have been proposed in order to treat building dried water and rainwater.

First of all, the MBR process purifies not only particulate pollutants contained in raw water but also dissolved pollutants when applied in parallel with biological treatment. However, the membrane separation (MBR) method simultaneously inhibits the growth of microorganisms, which are essential for biological treatment, in low-concentration raw water.

In addition, when the activated carbon adsorption method is applied, the filtration of the activated carbon and the method using the adsorption force are excellent in the removal of organic substances and odors. However, when the activated carbon adsorption method is used alone, the efficiency of decontamination of activated carbon is drastically deteriorated and the quality of water is getting worse. In order to overcome this problem, a sewage water treatment system and a rainwater treatment system which use activated carbon adsorption method and membrane method at the same time are desperately needed.

The sewage and rainwater treatment system (10) according to the embodiment of the present invention includes a collecting unit (100) in which the sewage S is stored; Wherein the microbubbles and the microbubbles are connected to each other when the microbubbles and the microbubbles are supplied to the microbubbles and the microbubbles are supplied to the microbubbles, And a contact device 300 having a contact space in which the ozone contacts the first process water 1 and the first process water 1 that have passed through the separation device 200, 20); And a filter material 400 having a filter material layer 430 for filtering foreign matter not treated in the first treatment water 1 that has passed through the floating separation part 20 to generate second treatment water 2, .

The collecting unit 100 collects and collects the dried water S and rainwater of the building. At this time, the water collecting part 100 forms an auxiliary collecting part for separately storing rainwater. This is to manage the sewage S (S) and rainwater differently from each other due to their properties and pollution degree.

The collecting unit 100 collects sludge generated in a screen tank for collecting organic matters or minerals such as stenoses and soil, which are heavy foreign substances, from the introduced sewage S, and a water collecting tank for collecting the precipitated sewage water and the system And may include a storage vessel capable This is not intended to limit the form of the collecting part 100.

The floating separation unit 20 includes a separation device 200 that receives the processed water S and separates contaminants of the processed water S by using fine bubbles and a first treated water 1 And a contact device 300 for increasing the ozone dissolution rate.

1 or 3, the separating apparatus 200 includes a suction pump 210 for sucking the sewed water S of the collecting unit 100; A first tank 230 for supplying the sewage water S from the suction pump 210 and storing the sewage water S; A bubble generator 250 connected to the interior of the first tank 230 and injecting fine bubbles and ozone into the processed water S; And a first outlet 270 formed at an upper portion of one side of the first tank 230 for discharging the first treated water 1 to the outside.

The suction pump 210 delivers the sewed water S stored in the water collecting part 100 to the first tank 230. At this time, the suction pump 210 adjusts the suction valve 211 and the discharge valve 213, and injects an appropriate amount of the sewage water S into the first tank 230. It is appropriate that the suction pump 210 is discharged to the first tank 230 at a pressure of about 0.8 kgf / cm 2 or less.

In the first tank 230, a blocking wall 231, a rectifying wall 235, and a partition 233 are formed. At this time, the first tank 230 is preferably formed in a cylindrical shape or a polygonal shape. This is not to limit the shape of the first tank 230 to a cylindrical shape or a polygonal shape.

The blocking wall 231 is formed so as to extend to an inner upper portion of the first tank 230. At this time, one end of the blocking wall 231 is preferably opened. One end of the blocking wall 231 is disposed above the rotating portion 253.

When the sewed water S collides against the surface by the rotational force of the rotary part 253, the minute bubbles combined with the particles are separated from the sewage water S by the blocking wall 231. At this time, when the minute bubbles combined with the particles are separated from the sewage S, the blocking water 231 moves along the outer peripheral surface of the first treated water 1. Then, the blocking wall 231 guides the first treated water 1 to the first outlet 270.

The rectifying wall 235 is disposed above the blocking wall 231. The rectifying wall 235 extends downward from the upper portion of the first tank 230. At this time, the rectifying wall 235 is preferably formed vertically. When the particles of the sewed water S and the minute bubbles hit the blocking wall 231, the fine bubbles combined with the particles guide the upper wall of the first tank 230 to the rectifying wall 235. That is, the rectifying wall 235 guides the fine bubbles combined with the particles separated from the sawdust S to the upper portion of the first tank 230.

The rectifying wall 235 is disposed closer to the periphery of the first tank 230 than one end of the blocking wall 231. Further, the rectifying wall 235 is formed to have a larger opening area than the blocking wall 231 with respect to the transverse section. That is, the rectifying wall 235 is disposed between the periphery of the first tank 230 and one end of the blocking wall 231. At this time, the rectifying wall 235 and the blocking wall 231 are spaced apart from each other, and serve as a passage through which the first treated water 1 moves to a portion separated from the rectifying wall 235 and the blocking wall 231.

A foreign matter collector 239 may be disposed on the upper portion of the first tank 230 to remove microbubbles associated with the particles. That is, the foreign matter collector 239 is fixedly formed on the first tank 230 to collect fine bubbles combined with particles separated from the dried water S.

The foreign matter collector 239 may be connected to the foreign matter removing valve 237 to remove fine bubbles combined with the particles. At this time, the foreign matter removing valve 237 moves the fine bubbles combined with the particles to the collecting part 100.

Referring to FIG. 3, a partition 233 is formed at the lower end of the first tank 230. At this time, the partition 233 is formed to extend downward from the inside of the first tank 230 with respect to the transverse section, and to have a smaller width as it goes downward. That is, the partition 233 is formed in a hopper shape inclined to the lower portion of the first tank 230. This allows the partition 233 to collect the foreign substances injected from the suction pump 210 into the lower portion of the first tank 230. [

A foreign matter removing valve 237 for connecting the inside and the outside of the first tank 230 is formed in the lower part of the first tank 230. The foreign substance removing valve 237 is formed at the lower end of the tank. Then, the foreign substance removing valve 237 opens and closes during cleaning and repair work. At this time, the foreign substance removing valve 237 discharges the foreign substances and the accumulated sludge formed at the lower end of the first tank 230 to the outside at the time of work such as cleaning and repair.

A first outlet 270 is formed in the upper portion of the first tank 230. At this time, the first outlet 270 discharges the first treated water 1 to the outside of the first tank 230, and supplies the first treated water 1 to the upper part of the contact device 300. Then, the first outlet 270 collides with the blocking wall 231 to transfer the purified first treated water 1 to the second tank 310.

Referring to FIG. 3, the bubble generator 250 combines the particles of the sawtooth water S and the minute bubbles. The bubble generator 250 rotates the dried water S in the first tank 230 to generate a vortex.

One side of the bubble generator 250 is formed of a motor 251 disposed at the upper end of the first tank 230 and the other layer is formed extending from the shaft of the motor 251, S) within the first tank (230); And an injection unit 255 for injecting air and ozone into the dried water S.

The motor 251 is disposed on the outer circumferential surface of the first tank 230 and penetrates into the first tank 230 to fasten the shaft. The shaft rotates inside the first tank 230, and the rotating portion 253 is fastened. At this time, the rotation unit 253 receives power from the shaft, rotates, and rotates inside the first tank 230 to generate a spiral vortex with respect to the water multiple. Then, the rotation unit 253 generates minute bubbles due to the rotational force of the vortex. A plurality of vanes may be disposed on the outer circumferential surface of the rotary unit 253 to increase the rotational force.

That is, the rotary unit 253 rotates the sawtooth water S so that the sewed water S hits the cutoff wall 231. Then, when the sewage S is hit against the blocking wall 231, the fine bubbles combined with the particles are separated to obtain the first treated water 1.

The injection unit 255 injects air and ozone into the sewage S or further injects microbubbles into the sewage S as well. Then, the injection unit 255 injects air and ozone to improve the oxidizing power. At this time, charging of the microbubbles occurs. In other words, fine bubbles attract particles because they electrostatically attract objects.

In addition, a separate backflow prevention device 254 is formed to prevent the injection part 255 from flowing back to the outside of the first tank 230. The injection unit 255 is connected to the ozone generator 256 from outside to supply the ozone to the rotation unit 253. In addition, the injection unit 255 may be provided with a separate supply valve 252 for supplying the ozone generator 256 and the backflow protector 254.

Referring to FIG. 1 or FIG. 4, the contact device 300 improves the ozone dissolution rate in the first treated water 1 that has passed through the separation device 200. This is to improve the purification efficiency of the first treated water 1 by improving the ozone dissolution rate.

The contact device 300 is divided into a plurality of parts in the second tank 310 and the second tank 310 receiving the first treated water 1 and ozone at the same time and the first treated water 1 and ozone An inner compartment 330 having a contact space in contact with the first compartment 330 and an inner compartment 330 adjacent to the inner compartment 330 of the plurality of compartments 330, And a second discharge port 370 for transferring the first treated water 1 that has been moved through the piping 350 and the piping 350 is formed.

The first treated water 1 purified by the separating apparatus 200 flows into the upper end of one side of the second tank 310. The second tank 310 contacts the first treated water 1 with the ozone to increase the dissolution rate. At this time, the second tank 310 is preferably formed in a cylindrical shape or a polygonal shape. This is not to limit the second tank 310 to a cylindrical or polygonal shape.

The inner compartment (330) divides the interior of the second tank (310) into a plurality of spaces. The inner compartment 330 is closed by the vertical partition 333 and the horizontal partition 331. That is, the inner compartment 330 forms one enclosed space.

At this time, the transverse bulkhead 331 of the inner compartment 330 divides the first treated water 1 into a plurality of sections while preventing the first treated water 1 from being directed to the lower portion of the second tank 310. The vertical partition wall 333 of the inner compartment 330 prevents the first treated water 1 from flowing from one side of the second tank 310 to the other side.

That is, the vertical barrier ribs 333 of the plurality of vertical barrier ribs 333 extend from the upper part to the lower part and the adjacent vertical barrier ribs 333 extend from the lower part to the upper part. The use of the horizontal barrier ribs 331 and the vertical barrier ribs 333 has the effect of changing the movement path and the moving speed of the first treated water 1. This is because the first treated water 1 comes into contact with the ozone as much as possible to have a contact space inside the contact device 400.

4 or 5, when the first treated water 1 is filled in the inner compartment 330, the piping unit 350 is connected to the first treated water 1 according to the position of the piping unit 350, Lt; / RTI > For example, as shown in FIG. 4, the piping unit 350 may control the movement path of the first treated water 1 and the ozone in the second tank 310, And the piping portion 350 is disposed away from one side of the adjacent inner compartment 330. The piping portion 350 is spaced away from one side of the plurality of inner compartments 330, Are arranged alternately. This is to form the contact area and the movement path within the second tank 310 as long as possible in order to improve the ozone dissolution rate of the first treated water 1.

Referring to FIG. 5, the piping unit 350 connects the inner compartment 330 and the adjacent inner compartment 330 with each other. That is, a first inlet / outlet 351 is formed at an upper portion of the pipe portion 350, and a second inlet / outlet 353 is formed at a lower portion of the pipe portion 350. That is, the piping unit 350 moves the first treated water 1 to the inner compartment 330 adjacent to the inner compartment 330.

Then, the piping unit 350 moves the first treated water 1 from the upper end to the lower end of the second tank 310. That is, the piping unit 350 moves the first treated water 1 into the inner compartment 330 adjacent to the inner compartment 330 of the plurality of inner compartments 330.

The first treated water 1 is injected through the first inlet 351 and the first treated water 1 is injected into the adjacent inner compartment 330 through the second inlet 353, . Conversely, the first treated water 1 may be injected through the second inlet / outlet 353 and moved to the internal compartment 330 through the first inlet / outlet 351.

The pipe portion 350 is suitably formed in a cylindrical shape, a square shape, and a polygonal shape. This is not intended to limit the shape of the piping section 350.

A second outlet 370 is formed on the upper portion of the second tank 310. Then, the second outlet 370 moves the first treated water 1 to the filtration apparatus 400. At this time, the second outlet 370 is formed on the opposite side from which the first treated water 1 is introduced. This is to increase the ozone dissolution rate with the first treated water 1 in the second tank 310.

Further, the second outlet 370 prevents the backflow of the filtration apparatus 400. [ At this time, one side of the second outlet 370 passes through the transverse bulkhead 331 and is formed as a lower portion of the second tank 310, and the other side is connected to the filtration apparatus 400. Then, one side of the second outlet 370 is disposed below the second tank 310, thereby generating a water pressure difference. That is, the second outlet 370 prevents the second treated water 2 from moving to the contact device 300 due to the hydraulic pressure difference in the filtration device 400 in the reverse flow.

A foreign matter removing valve 237 for connecting the inside and the outside of the second tank 310 is formed in the lower part of the second tank 310. The foreign substance removing valve 237 is formed at the lower end of the second tank 310. Then, the foreign material removing valve 237 is opened and closed for cleaning and repairing the internal compartment 330. At this time, the foreign substance removing valve 237 discharges the foreign substances and the accumulated sludge formed at the lower end of the second tank 310 to the outside at the time of work such as cleaning and repair.

1 and 6, a distribution pipe 411 for introducing the first treated water 1 is formed in an upper portion of the filtration apparatus 400, and a third pipe 411 for introducing the first treated water 1 A tank 410 and a distribution tank 411. The filter 410 is disposed in the lower portion of the third tank 410 and filters the first treated water 1 to generate second treated water. 430 and a water tank 450 for storing the second treated water 2 purified.

The upper end of the third tank 410 receives the first treated water 1 and the lower end discharges the second treated water 2 to the outside. The third tank 410 is formed of a metal material in consideration of durability and corrosion resistance. At this time, the third tank 410 is preferably made of stainless steel. This is not to limit the material of the third tank 410 to stainless steel. In addition, the third tank 410 may be subjected to surface treatment with epoxy or the like in consideration of the influence of chlorine ions, OH ^- radicals, and the like contained in the dried water S to ensure durability.

The distribution pipe 411 is formed on the upper side of the third tank 410 and moves the first treated water 1 through the contact device 300 to the third tank 410.

The backwash discharge pipe 470 is disposed between the distribution pipe 411 and the filter material layer 430 and regulates the flow rate of the first process water 1. That is, the backwash discharge pipe 470 regulates a predetermined flow rate of the first process water 1 within the third tank 410.

At this time, the backwashing discharge pipe 470 always moves pollutants and foreign matter to the catching part 100. This is because the injected first treated water 1 always injects a larger amount than the purified second treated water 2. That is, the counterflow discharge pipe 470 always regulates a constant flow rate in the third tank 410.

Further, the backwashing discharge pipe 470 always regulates a predetermined flow rate during purifying or backwashing.

The filter material layer 430 is disposed below the distribution pipe 411 and filters and adsorbs the first treated water 1 in the third tank 410 to purify the second treated water 2. That is, when the first treated water 1 moves downward due to gravity, the filter medium layer 430 filters the first treated water 1 to obtain purified second treated water 2.

It is preferable that the filter material layer 430 is sequentially provided with sand, an upper separation barrier plate 431, activated carbon, sand, gravel charcoal, and a lower separation prevention plate 433. At this time, the upper part of the upper departure prevention plate 431 forms sand, so that the sand can be replaced periodically.

In addition, the filter material layer 430 controls the type and composition ratio of the filter material according to the first treated water 1. At this time, the filter medium layer 430 is preferably composed of 70% by weight of activated carbon, 20% by weight of filter paper (sand), and 10% by weight of filtration sludge (gravel).

The upper detachment prevention plate 431 is formed of a stainless steel (STS) perforated plate, a stainless steel (STS) mesh net, a polyethylene (PE) supporting net, and a stainless steel (STS) perforated plate from above. At this time, the upper departure prevention plate 431 is formed on both sides with a stainless steel (STS) perforated plate, thereby preventing the activated carbon from being detached during purification and backwashing.

The lower detachment prevention plate 433 is formed of a stainless steel (STS) mesh net, a polyethylene (PE) net, and a stainless steel (STS) perforated plate from above. At this time, the lower separation preventing plate 433 has an effect of preventing the separation of sand and activated carbon at the time of backwash by arranging a stainless steel (STS) perforated plate at the bottom. The lower detachment prevention plate 433 prevents the filter medium layer 430 from being lost due to the flow rate of the treated water supplied from the backwash pump 610 to be described later. More preferably, the upper detachment prevention plate 431 and the lower detachment prevention plate 433 prevent the activated carbon from escaping.

The water tank 450 is connected to the filter material layer 430 and stores the second treated water 2. That is, the water tank 450 is connected to the lower departure prevention plate 433, and the purified second treated water 2 flows into the inside and stores it. The second treated water 2 is transferred to the filter 500 through the treated water pump 451 at one side of the water tank 450.

The treated water pump 451 is provided with a treated water intake valve 453, a treated water discharge valve 455 and a treated water conveyance valve 457 to adjust the capacity of the second treated water 2. The treated water pump 451 has a motorized valve 459 that is automatically driven by selecting a treatment process and a backwash process.

At this time, when the second treated water 2 is moved from the water tank 450 to the filter 500, the treated water pump 451 moves the second treated water 2 to the filter 500, (451) is normally operated, and the water treatment motor valve (459) is opened to close the backwash motor valve (630).

The backwash pump 610 is connected to the water tank 450. The backwash pump 610 sucks the third treated water 3 stored in the treated water storage tank 600. At this time, the backwash pump 610 regulates the backwash flow rate of the third treated water 3 by the backwash suction valve 613 and the backwash discharge valve 611. In addition, the backwash pump 610 is provided with a backwash motor valve 630 that is automatically operated by selecting a treatment process and a backwash process.

Then, during backwashing of the filtration apparatus 400, the treatment water pump 451 for sucking the second treated water 2 is stopped. When the movement of the second treated water 2 stops, the process water hydraulic valve 459 gradually stops the flow of the flow.

The backwash motor valve 630 and the backwash pump 610 are then opened to transfer the third treated water 3 of the treated water storage tank 600 to the filtration apparatus 400. The third treated water 3 of the treated water storage tank 600 is injected into the water tank 450 so that the contaminants adsorbed to the filter medium layer 430 are mixed with the second treated water 2 and the third treated water 3, Together with the second tank 410, At this time, the floating contaminants and foreign matter move to the counterflow pipe 470. Then, the backflow discharge pipe 470 moves the contaminants and foreign matter to the collection tank 100.

The filter 500 receives the rainwater from the second treated water 2 or the auxiliary collected portion and filters the filtered water with the third treated water 3. At least one filter 500 is disposed and is replaceable.

At this time, the pressure reducing valve 510 is disposed in the filter 500 before the second treated water 2 is injected. That is, the pressure reducing valve 510 regulates the pressure of the second treatment water 2 before the filter 500 is injected. When the pressure of the second treated water 2 supplied from the treated water pump 451 is supplied to the filter 500 at about 0.8 to 1.2 kgf / cm 2, it exceeds the allowable operating pressure of the filter 500. Therefore, the pressure reducing valve 510 is installed to lower the pressure of the second treatment water 2 by itself.

The filter 500 may be formed using at least one of a globe bag filter, a globe sideline filter, a globe carbon filter, and a globe membrane filter, or two kinds of filters may be used in combination with each other.

The filter 500 transfers the third treated water 3 to the treated water storage tank 600. At this time, the filter 500 may be provided with a flow meter 530 for checking the flow rate of the third treated water 3.

The treated water storage tank 600 stores the third treated water 3. That is, the process water storage tank 600 stores the third process water 3 purified through the filter 500. [

The process water storage tank 600 is connected to the backwash pump 610. Then, the process water storage tank 600 supplies the third treatment water 3 to the backwash pump 610 during the backwashing of the filtration apparatus 400.
