Here, the rectifying member 330 is composed of a rectifying plate 331 which is erected vertically and an inclined plate located behind the rectifying plate 331.

Then, the inclined collection chute 340 is composed of a screen of the screw conveyor is installed inclined toward the other end from the lower end of one side inside the immersion cleaning unit to discharge the settled sediment to the outside.

In addition, the inclined collection chute 340 is provided in front of the rectifying member 330 to filter out contaminants and organic matter, and the contaminants and organic matter filtered by the rectifying member 330 is discharged to the outside through the collection chute 340 with the settling. .

In addition, the supernatant in the inflow water from which the contaminants, the organic matter, and the sediment is removed is circulated again through the supernatant outlet pipe 320 to the settling tank 200.

Referring to the operation of the contaminant treatment device configured as described above are as follows.

As shown in FIG. 8, when the inflow water flows into the inlet 110 of the contaminant removal tank 100, the inclination screen 120 provided inside the contaminant removal tank 100 is driven to externally trap the contaminants included in the inflow water. To be removed. At this time, the discharged junk is contained in the junk box 140. In addition, the inflow water from which the contaminants are removed by the inclination screen 120 is introduced into the settling tank 200 through the inclined water channel 130 connected to the settling tank.

At this time, the inflow water supplied to the settling tank 200 is introduced in the tangential direction of the lower circular sedimentation tank 210 through the inclined water channel 130 to generate a swirl flow.

On the other hand, when the screen 120 of the contaminant removal tank 100 is broken or inflow water is excessively introduced, a part of the inflow water of the contaminant removal tank is bypassed to the precipitation washing tank 300 through the overflow port 310. Thus, the influent does not overflow to the outside.

The inflow water flowing into the inlet port of the circular sedimentation tank 210 of the sedimentation tank via the inclined water channel 130 of the contaminant removal tank 100 is settled along the inlet flow passage 225 of the circular sedimentation tank 210. While moving in the circumferential direction of the bottom of the circular immersion tank 210 and the bottom of the immersion separation member 220 through the through hole 222 of the lower end of the immersion separation member 220. Here, the sedimentation included in the inflow water is settled inside the conical hopper 214 formed in the lower portion of the circular sedimentation tank 210 by the load of the sedimentation, the inlet water is removed the circular sedimentation backflow prevention hole 224 It is introduced into the sedimentation separating member 220 through. At this time, the inside of the sedimentation separation member 220 is rotated by the impeller 234 for generating a swirl flow to generate a swirl flow, part of the sediment contained in the inflow water flowing through the circular sedimentation backflow prevention hole 224 By being collected by the center of the bottom portion 221 of the sedimentation separation member is settled inside the conical hopper (214). In addition, the supernatant of the inflow water rising by the swirl flow is discharged to the outlet 212 of the circular sedimentation tank through the outlet pipe 223 provided at the upper end of the sedimentation separating member 220.

Then, the sedimentation precipitated in the conical hopper 214 is transferred to the inside of the sedimentary washing tank 300 by the transfer pipe 241 by the operation of the needle pump between the needle feed pump (242). At this time, the vortex generating member 250 is driven to induce easy discharge of the sinter, and the vortices are generated in the sinter while stirring the chopped sintered material by introducing the washing water or the washing air for about 10 to 15 seconds at a predetermined cycle. The settled sediment is rapidly transported on the transfer pipe 241 by the suction force of the needle pump 242, and is supplied to the settling washing tank 300. That is, by quickly discharging the sediment settled in the conical hopper 214 to the needle pump 242, the organic matter attached to the sedimentation does not decay or scum is generated.

Impinge on (332a) and step by step through the corrugated bone, the flow rate and vortex is reduced to increase the settling efficiency.

At this time, the organic matter adhered to the sediment by washing water or washing air sprayed from the sedimentary washing water nozzle 332b installed to correspond to the lower end of the washing wrinkle plate 332a, the sediment is precipitated and separated from the sediment Organic matter is re-introduced into the circular sedimentation tank 200 through the supernatant outlet 320 located in contact with the sedimentary cleaning tank 300 and the circular sedimentation tank 200 together with water to precipitate the sediment not separated. We aim at efficiency improvement.

In addition, the immersion cleaning tank 300 is provided with a rectifying plate 331 for reducing the vortex and the flow rate generated by the washing water or the cleaning air sprayed from the washing water nozzle 332b, the back of the rectifying plate 331 An inclined collection chute 340 is provided, and the collection chute 340 passes through the rectifying plate 331 and the sediment that moves without settling with the water collides with the inclined plate 332 to collect the chute 340. It is equipped to settle on the ride. At this time, the precipitated sediment is discharged through the collection chute by the inclined sediment conveying conveyor.

Subsequently, the acupuncture supplied to the sedimentation washing tank 300 is washed with the washing water of the sedimentation washing tank 300, and the organic matter attached to the sedimentation is washed. Then, the washed sediment is settled in the sedimentation cleaning tank 300, the precipitated sediment is discharged to the outside by the drive of the collection chute 340, that is, the screw conveyor is installed obliquely and is contained in the sediment box 350. In addition, the contaminants and organics included in the influent water bypassed in the contaminant removal tank 100 are filtered by the rectifying member 330 provided in front of the collection chute, and the contaminants and organics filtered by the rectifying member 330 together with the settling. It is discharged to the outside through the collection chute 340 is contained in the immersion box 350. In addition, the supernatant in the inflow water from which the contaminants, the organic matter and the sediment are removed is introduced again into the sedimentation tank 200 through the supernatant outlet pipe 320, and the inflow water introduced into the sedimentation tank 200 is settled through the flow path of the sedimentation tank 200. After removing the discharge through the outlet pipe 223 is discharged to the outlet 212 of the circular sedimentation tank.

Thus, one embodiment of the present invention is provided with a sedimentation tank consisting of a circular tank having a sediment removal function and sedimentation removal function at the same time, having a sediment removal function and a sedimentation removal function integrally, and take up a small area with good sedimentation efficiency. By doing so, it takes up much less installation space than conventional rectangular contaminants and sediment removers, so that it can be used in small sewage treatment plants, easy to maintain, and reduce maintenance costs.

In addition, when the screen of the contaminant removal tank is broken or the inflow of the inflow water is excessive, the inflow of the contaminant removal tank is bypassed to the sedimentation cleaning tank, and the sediment deposited in the sedimentation tank is transferred to the sedimentation cleaning tank to clean the organic matter attached to the sedimentation tank. Next, the sediment and sedimentation of the sedimentation cleaning tank is discharged to the outside, and the inflow water from which the contaminants have been removed is fed back to the sedimentation tank so that some of the sediment contained in the influent is removed. Therefore, there is no need to install a separate bypass screen facility or standby facility, thereby reducing installation cost.

In addition, by quickly discharging the sediment settled in the sedimentation tank with a needle pump, the organic matter attached to the sedimentation does not decay or scum can be generated to improve the cleaning effect of the sedimentation.

The trapezoidal sedimentation reflux prevention hole 224a connecting the space between the circular sedimentation tank 210 and the sedimentation separation member 220 and the inner space of the sedimentation separation member 220 is reduced to have a minimum open volume and thus the sedimentation separation member ( Scum removal, characterized in that the inner space is not affected by the vortex environment of the space between the circular sedimentation tank 210 and the sedimentation separation member 220 to maintain the flow rate at a low speed to separate the sedimentation due to the difference in specific gravity Swirl flow type dust collector equipped with a part.
