The contaminants settled while the contaminated water flows from the lower side to the upper side of the first sedimentation vessel 10 are moved to the second sedimentation vessel 130 side by the first outlet 13.

The rectifying pipe 20 is disposed in the up and down direction inside the first settling tank 10, and introduces the contaminated water into the first settling tank 10. According to this embodiment, the upper side of the rectifying pipe 20 is provided with a connection pipe 120 for inducing contaminated water to the rectifying pipe 20, the pollution flowing into the first region (R1) of the underground tank 190 Water is introduced into the first settling tank (10) via the connecting pipe (120). However, the installation position of the connection pipe 120 is not limited to the upper side of the rectifying pipe 20.

In the present embodiment, the rectifying pipe 20 is disposed in the center of the first precipitation tank 10, the lower end of the rectifying pipe 20 is provided with a guide plate 21. The guide plate 21 is provided at the lower end of the rectifying pipe 20, and is formed to be inclined toward the inner circumferential surface of the first precipitation tank 10 as it extends downward. That is, the inner diameter of the upper end of the guide plate 21 connected to the rectifying pipe 20 is smaller than the inner diameter of the lower end of the guide plate 21.

The space between the end of the guide plate 21 and the first inclined surface 11 forms a flow path of the contaminated water when the contaminated water is filled up from the lower end of the first settling tank 10 and rises.

1 and 3, one end of the first inclined plate 30 is coupled to the inner circumferential surface of the first sedimentation vessel 10, and the other end extends inclined downward toward the rectifying pipe 20. do.

Specifically, one end of the first inclined plate 30 is coupled to the inner circumferential surface of the first precipitation tank 10 by the first connection member 40. A plurality of first connecting members 40 are disposed along an edge circumferential direction of the first inclined plate 30, and inner circumferential surfaces of the first inclined plate 30 and the first settling tank 10 are spaced apart from each other. Is formed.

Referring to FIG. 2, a space in which one end of the first inclined plate 30 and the inner circumferential surface of the first settling vessel 10 are spaced apart when the contaminated water moves from the bottom of the first settling vessel 10 to the upper side thereof. The first sub-flow path 80 through which the contaminated water passes is formed.

1 and 5, one end of the second inclined plate 50 is coupled to the outer circumferential surface of the rectifying pipe 20, and the other end thereof is downwardly directed toward the inner circumferential surface of the first precipitation tube 10. Extends obliquely. In the present embodiment, the first inclined plate 30 and the second inclined plate 50 are alternately arranged in the vertical direction.

Specifically, one end of the second inclined plate 50 is coupled to the outer circumferential surface of the rectifying pipe 20 by the second connecting member 60. The second connecting member 60 is disposed in plural along the edge circumferential direction of the second inclined plate 50, and the outer circumferential surfaces of the second inclined plate 50 and the rectifying pipe 20 are spaced apart from each other. .

Referring to FIG. 4, the space where one end of the second inclined plate 50 and the outer circumferential surface of the rectifying pipe 20 are spaced apart from each other when the contaminated water moves from the lower end of the first settling tank 10 to the upper side thereof. Passing second sub-flow path 90 is formed.

In addition, the space formed by the end of the first inclined plate 30 and the end of the second inclined plate 50 spaced apart from each other when the contaminated water moves from the lower end of the first settling tank 10 to the upper side, A main flow path 70 is formed to move.

According to the present embodiment, the width of the first and second sub flow paths 80 and 90 is smaller than the width of the main flow path 70. Specifically, the first and second sub-flow paths 80 and 90 have a width of about 10 to 15 mm. On the other hand, the width of the main flow path 70 may be formed to about 4cm.

The reason for setting the width of the first and second sub flow paths 80 and 90 to be smaller than the width of the main flow path 70 is to determine the amount of contaminated water flowing in the first and second sub flow paths 80 and 90. This is to control the flow rate to be less than the flow rate of the contaminated water flowing in the main flow path (70).

The second settling tank 130 is disposed outside the first settling tank 10, the lower side is provided with a second inclined surface 131 to which the pollutant slips. According to the present embodiment, a second discharge port 133 is formed at the lower end of the second precipitation tank 130 through which the sedimented pollutants are discharged to the third precipitation tank 140.

The first partition plate 170 is disposed in the vertical direction between the first sedimentation vessel 10 and the second sedimentation vessel 130. The first partition plate 170 partitions a space between the first settling vessel and the second settling vessel 130.

A space formed by the first partition plate 170 and the outer circumferential surface of the first precipitation tube 10 forms a first lower flow passage 151. The contaminated water flows into the rectifying pipe 20, is filled from the lower side of the first sedimentation vessel 10, and overflows to the second sedimentation vessel 130 from the upper side, and has a second needle along the first lower passage 151. Flow down the tradition (130).

A space formed by the inner circumferential surface of the first partition plate 170 and the second precipitation tank 130 forms a first upper flow path 152. The contaminated water descending to the lower end of the second settling tank 130 along the first lower channel 151 flows upward along the first upper channel 152 and then flows to the third settling tank 140. .

In this case, the width of the first lower channel 151 is smaller than the width of the first upper channel 152. That is, the first partition plate 170 is installed closer to the first settler 10 between the first settler 10 and the second settler 130.

The contaminated water flowing along the first lower channel 151 freely falls, and the contaminated water flowing along the first upper channel 152 flows while being filled from the lower end of the second settling tank 130. The moving speed of the contaminated water flowing through the first upper flow passage 152 is relatively slower than the moving speed flowing through the first lower flow passage 151. Therefore, the width of the first upper flow passage 152 is larger than the width of the first lower flow passage 151 in order to increase the flow path of the slowly moving contaminated water to secure a sufficient settling time.

The third settler 140 is disposed outside the second settler 130. The lower side of the third settling tank 140 is provided with a third inclined surface 141, the contaminant slips down, and a third hopper portion 142 is provided at the lower end of the contaminant.

According to the present embodiment, contaminants are transferred to the third settler 140 through the first outlet 13 of the first settler 10 and the second outlet 133 of the second settler 130. It moves and gathers in the 3rd hopper part 142 provided in the lower end. The contaminant moving pipe 250 is connected to the third hopper unit 142 to collect and remove contaminants. The contaminant moving pipe 250 is provided with a suction pump 260, and periodically The contaminants filled in the hopper 142 are removed.

The second partition plate 180 is disposed in the vertical direction between the second precipitation vessel 130 and the third precipitation vessel 140. The second partition plate 180 partitions a space between the second precipitation vessel 130 and the third precipitation vessel 140.

The space formed by the outer circumferential surface of the second partition plate 180 and the second precipitation container 130 forms a second lower flow path 161. The contaminated water flowing into the third settling tank 140 through the first upper flow passage 152 flows downward along the second lower flow passage 161.

The space formed by the second partitioning plate 180 and the inner circumferential surface of the third precipitation tube 140 forms a second upper flow passage 162. The contaminated water descending to the lower end of the third settling tank 140 along the second lower flow passage 161 flows upward along the second upper flow passage 162 and is then discharged through the discharge pipe 110.

In this case, the width of the second lower channel 161 is smaller than the width of the second upper channel 162. That is, the second partition plate 180 is installed closer to the second precipitation vessel 130 between the second precipitation vessel 130 and the third precipitation vessel 140.

The reason why the second partition plate 180 is installed closer to the second precipitation tank 130 is the same as that of the first partition plate 170 described above, and thus, a detailed description thereof will be omitted.

On the other hand, the non-point source treatment apparatus according to the present embodiment is provided in the underground tank 190 buried in the basement, the underground tank 190 is the first area (R1) and the first contaminated water flows into the interior and the The first, second, and third sedimentation tanks 10, 130, and 140 are divided into a second region R2, and the first region R1 and the second region R2 are divided by the partition wall 270. The first region R1 and the rectifying pipe 20 are connected by a connecting pipe 120, and contaminated water flows into the first settling tank 10 along the rectifying pipe 20 via the connecting pipe 120. do.

As shown in FIG. 1, the first region R1 is where the polluted water first enters, and contaminated water flows from the menhole 280 provided above the first region R1, or an inlet pipe is provided separately. Contaminated water is introduced through 290. That is, rainwater containing contaminants flows into the first region R1.

The first region R1 is divided into an upper portion A1 and a lower portion A2 by the mounting plate 200. The mounting plate 200 is installed in the transverse direction with respect to the first region R1.

The installation plate 200 is provided with a plurality of induction pipes 210 for communicating the upper portion A1 and the lower portion A2. As shown in FIG. 6, a plurality of through-holes 220 are formed in the induction pipe 210 protruding to an upper portion of the mounting plate 200. The contaminated water entering the upper portion A1 of the first region R1 is caught by the through-hole 220 before the contaminant contained in the contaminated water is caught by the through hole 220 before flowing to the lower portion A2 via the induction pipe 210. do.

As shown in FIG. 7, at least two entrance and exit holes 230 through which the worker enters and exits are formed in the installation plate 200. The operator needs to enter the lower portion A2 of the first region R1 in order to periodically remove the contaminants collected in the first region R1. Let's do it. Toxic gas is present in the lower portion (A2) can be usefully used when a quick escape is required.

The access net 230 is provided with a walking net 240 to filter contaminants, and the walking net 240 is detachably installed at the access hole 230. When the worker enters the lower portion of the first area R1 through the access hole 230, the worker removes the step network 240 and enters and exits.

Hereinafter, the operation and effects of the initial rainwater treatment settler of the present invention according to the above configuration will be described in detail.

According to the present embodiment, first, contaminated water containing contaminants is introduced into the upper portion A1 of the first region R1 of the underground tank 190. The contaminated water flows from the upper part A1 to the lower part A2 through the induction pipe 210, and at this time, the contaminant is primarily by the through-hole 220 and the walking network 240 of the induction pipe 210. Is removed.

The contaminated water flowing into the lower portion A2 is introduced into the first settling tank 10 via the connection pipe 120 and the rectifying pipe 20. The contaminated water is filled from the lower end of the first settling tank (10).

The contaminated water contained in the contaminated water is precipitated while the contaminated water flows from the lower portion to the upper portion of the first sedimentation vessel 10 as follows.

As shown in FIG. 1, the contaminated water filled in the lower part of the first settling tank 10 flows upward along the space formed between the guide plate 21 and the first inclined plate 30.

At this time, a part of the contaminated water flows upward through the first sub flow path 80. That is, a large amount of contaminated water moves upward along the space formed between the guide plate 21 and the first inclined plate 30, and a small amount of contaminated water moves upward through the first sub-flow path 80. do.

At this time, the contaminants contained in the contaminated water flowing between the guide plate 21 and the first inclined plate 30 are settled along the guide plate 21 due to natural precipitation, and the pollution slipped along the guide plate 21. The material moves downward along the first inclined surface 11 of the first precipitation vessel 10 and descends to the second precipitation vessel 130 through the first outlet 13.

In addition, the space between the first swash plate 30 and the inner circumferential surface of the first settling tank 10 is to secure a time for the pollutant, such as sand to settle while the flow rate of the contaminated water is somewhat slow. In this process, contaminants contained in the contaminated water are sufficiently precipitated.

Subsequently, a large amount of contaminated water from the contaminated water moving upward along the guide plate 21 and the first inclined plate 30 is formed by the first inclined plate 30 and the second inclined plate 50. Move upward along 70.

In addition, a small amount of contaminated water moves to the second sub-flow path 90 formed to be spaced apart from the outer circumferential surface of the second inclined plate 50 and the rectifying pipe 20.

The small amount of contaminated water flowing into the second sub-flow path 90 is sufficient to allow the contaminants contained in the contaminated water to settle while the flow rate is slightly lowered in the space between the second inclined plate 50 and the rectifying pipe 20. You will have time.

Meanwhile, the contaminated water passing through the main flow path 70 further moves upward along the space formed between the second inclined plate 50 and the first inclined plate 30.

As such, when the contaminated water flows to the upper part of the first settling tank 10, the contaminated water flows along the main flow path 70 in the zigzag direction, and is slowly moved upward through the first and second sub flow paths 80 and 90. Ensure sufficient settling time of contaminants while moving to.

The contaminated water flowing up to the upper part of the first settling tank 10 flows to the second settling tank 130 and passes through the first lower channel 151 and the first upper channel 152 before the third settling tank ( Overflow to 140). At this time, the contaminant settled in the second sedimentation vessel 130 through the second outlet 133 provided in the lower portion of the second sedimentation vessel 130 is the third hopper portion (3) 142). The contaminants collected in the third hopper 142 are periodically removed by pumping to the suction pump 260.

Subsequently, after passing through the second lower flow passage 161 and the second upper flow passage 162 of the third settling tank 140 sequentially, the discharge is discharged through the discharge pipe 110.

As such, in the non-point source treatment apparatus according to an embodiment of the present invention, since the contaminated water passes through the first, second, and third settling tanks (10,130,140), the flow path is secured and contaminants contained in the contaminated water are precipitated. It secures sufficient time and provides the effect of improving the sedimentation efficiency by securing enough space for the pollutants contained in the contaminated water to settle.

In addition, when the contaminated water moves from the lower portion to the upper portion of the first settling tank 10, it forms an zigzag flow path to provide a time to ensure that the contaminants contained in the contaminated water can sufficiently settle.

In addition, the first sub-flow path (80) and the second sub-flow path (90) are formed separately, so that a small amount of contaminated water can move through the first and second sub-flow paths (80, 90), 1 in the space formed between the settling tank 10 and the first inclined plate 30 and the space formed between the rectifying pipe 20 and the second inclined plate 50, the flow rate of the contaminated water is slowed down. Ensure sufficient time for natural settling.

In addition, the first inclined plate 30 and the second inclined plate 50 are formed to be inclined downward, the space between the first settling tank 10 and the first inclined plate 30 and the first of the rectifying pipe 20 The space between the two inclined plates 50 provides the effect provided as a space for activating the precipitation.

In addition, the contaminated water is introduced into the first region R1 of the underground tank 190 to remove contaminants first and then pass through the first, second, and third settling tanks 10, 130, and 140 to improve the purification efficiency of the contaminated water. Let's do it.
