The present invention relates to a water treatment apparatus for sedimentation and suspended solids which can simultaneously remove not only earth and sand contained in sewage but also suspended matter suspended in sewage.

With the increase of the population, as the industry develops, the amount of waste water discharged from homes and factories is increasing.

These sewage and waste waters are called sewage along with rainwater, and these sewage contain a large amount of pollutants, and if discharged as it is, the water quality is greatly deteriorated. do.

On the other hand, various contaminants are introduced into the water treatment facility along with the wastewater and wastewater in various pumping stations such as intake pumping stations and relay pumping stations.If the pollutants contained in the wastewater are not properly removed, the pumps or machinery installed in the pumping station Not only will there be breakdowns, but the transition to the next process will not take place, causing the entire facility to become useless.

For this reason, in most water treatment facilities, a sedimentation device or a settlement is installed between a conduit and a sedimentation basin, and the water sinks like a small gravel or sand contained in the waste water and sinks into water like plastic bottles or twigs. The floating float is to be removed by physical means.

By the way, the sewage system of large cities in Korea is mostly joined, and the urbanized area is composed of flat land and slopes. In this type of heavy rain, a large amount of rainwater flows into the sewage from the mountains behind it, and in the process, a lot of sediment flows into the sewage system, causing sedimentation of the flat sewage pipes to be blocked and sewage overflow, which causes flooding of the city.

As such, the sediment discharged during heavy rain has a large change in flow rate according to the intensity of the rainfall, and especially during heavy rain, the flow rate is very large, and thus, the general sedimentation area does not provide the effect of sedimentation. Of course, if there is a large land there is a plan to install a large settlement, but there is a problem in the practical application because it is economically troubled and difficult to maintain.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a water treatment apparatus for sedimentation and float removal, which not only removes soil contained in sewage during heavy rain, but also easily removes floating matter suspended in water. .

An object of the present invention described above, the sewage duct in which a circular flow path is formed so that centrifugal force is generated by the flow of sewage; A sediment separator formed in the outer wall side of the sewage duct to separate the sediment contained in the sewage by centrifugal force; Located in the outlet side of the sewage duct, formed to be recessed so as to be connected to the outside of the sediment separator is sedimentation and sediment is sedimentation sedimentation; is achieved by the water treatment apparatus for sedimentation and suspended matter removal.

Hereinafter, with reference to the accompanying drawings, the water treatment apparatus for removing the sediment and floats according to the present invention will be described.

As shown in FIG. 1, the water treatment apparatus of the present invention includes a sewage duct 10 largely divided into an inlet region A, an outlet region C, and a water treatment region B. As shown in FIG.

This sewage duct 10 is installed in the sewage pipe inlet or adjacent upstream to remove the soil and suspended matter contained in the valley water flowing from the mountain or green area, not the front of the pump and treatment facilities.

Here, the inlet region A and the outlet region C of the sewage duct 10 form a sufficient flow path through which the sewage flows. In the present embodiment, as shown in Figure 2, the sewage duct 10 of the inlet area (A) and the outlet area (C) has a wall shape upright perpendicular to both ends of the bottom of the flat plate-like shape. .

The water treatment area B is a place where the soil and suspended matter contained in the sewage are actually separated, and forms a circular flow path so that centrifugal force is generated when the sewage flows. Meanwhile, as illustrated in FIG. 3, the soil separation part 12 is recessed in the bottom portion close to the outer wall of the water treatment region B so that the soil is precipitated. At this time, the bottom of the water treatment area (B) is inclined surface 11 so that the earth and sand is pushed toward the outer wall of the sewage duct 10, that is, the soil separation section 12 by the centrifugal force generated while the sewage containing the soil passes through the circular flow path. Is formed. In this embodiment, the inclination angle of the inclined surface 11 is 5 to 30 degrees.

On the other hand, as shown in Figures 4 and 5, the end point of the water treatment region (B) is provided with a settling basin 13 for removing not only the earth and sand floating in the sewage. This sediment uses sedimental differences to settle or separate sediment and suspended solids from sewage.

That is, the earth and sand are collected by the soil separation part 12, and the sewage of the appropriate amount is configured to flow in the direction of the settling paper 13 outside the flow path at the end portion of the circular channel.

At this time, the suspended matter is also accumulated toward the outer wall by the same principle as the soil treatment to flow into the settlement 13, the first baffle so that the flow of the accumulation of sedimentation and suspended matter is guided to the settlement 13 14 is installed. In addition, a second baffle 15 is installed inside the settlement paper 13 to prevent the introduced floating material from overflowing to the outside of the settlement paper 13. That is, the second baffle 15 is installed at the lower side and spaced apart from the bottom of the settling basin 13 to suppress the flow of suspended matter floated in the sewage, but does not prevent the flow of sewage.

On the other hand, between the outer wall and the inner wall of the sewage duct 10 in which the sedimentation basin 13 is located, a first sluice 16 is installed to control the flow rate of sewage for maintenance of the settlement. In addition, the second sluice gate 17 and the third sluice gate 18 are also installed at the position where the sewage duct 10 enters the sedimentation basin 13 and the position where the sedimentation basin 13 is joined to the sewer duct 10 again. That is, the first sluice 16 is manipulated at the time of cleaning the suspended matter in the serge paper 13 to adjust the flow rate of the sewage flowing into the swash paper 13, the second sluice 17 and the third sluice 18 is settled ( 13) is installed in each of the inlet and outlet portion to function to prevent the sewage into the sedimentation basin 13 through the sewage duct 10 when removing the internal soil of the sedimentation basin (13).

Referring to the operation of the water treatment device for the sedimentation and suspended solids configured as described above are as follows.

When sewage flows in through the inlet area A of the sewage duct 10, the sewage continues to flow inside the water treatment area B of the sewage duct 10, which forms a circular channel, and is included in the sewage by the centrifugal force. Earth and sand are pushed to the outer wall side of the sewage duct (10). Therefore, the earth and sand pushed to the outer wall side falls to the recessed sediment separation section 12, and the contaminated suspended matter floats to the upper side of the sewage and is pushed to the outer wall side by centrifugal force similarly to the soil.

At this time, the earth and sand is prevented from being accumulated in any one of the earth and sand separation portion 12 by the continuous inflow and flowing sewage does not interfere with the flow of sewage.

Subsequently, most of the sewage flowing continuously passes through the first sluice gate 16 of the sewage duct 10 and is discharged to the exit area C, and part of the sewage duct 10 including the sediment and the suspended matter flows to the outer wall side of the sewage duct 10. The sewage is passed through the settlement 13 by the first baffle. As a result, the earth and sand are precipitated into the settled paper 13 formed more recessed than the sediment separator 12, and the suspended matter is further floated in a state of being blocked by the second baffle 15 while floating on the upper side of the settled paper 13 This will not last.

In this way, the suspended matter induced in the settlement is easily removed by manpower by controlling the water level in the settlement using each hydrology, and the soil deposited on the settlement can be removed using an appropriate equipment after emptying the sewage.

The sewage from which the earth and sand are separated through this process is discharged to the outlet area C while being joined with the sewage flowing through the sewage duct 10 through the third floodgate 18 of the settling basin 13.

As described above, according to the present invention, the centrifugal force can be used to remove not only the soil contained in the sewage but also to remove the suspended matter suspended in the sewage. As a result, it is easy to maintain and maintain the sedimentary sediment in the sedimentation end pipe line, and as a result, it is possible to promote safety of the discharged water and inundation.
