The present invention relates to a contaminated water purifying apparatus for purifying contaminated water generated from a pollutant, in particular a nonpoint source.

In general, water pollution sources are divided into point pollution sources and non-point pollution sources for the convenience of prevention and management.

Polluted water by point source is generated within a certain point or relatively narrow area, such as domestic sewage, industrial waste, livestock waste, etc., and it is possible to clarify the point where the pollutant is relatively specified and where the polluted water is generated. The treatment is relatively easy.

On the other hand, contaminated water from non-point sources is generated over a wide range of discharge paths, such as farms, yards, agricultural drainage, urban road drainage, etc., and because pollutants are difficult to identify and usually occur with rain, It is difficult to process because it has a large difference, difficult to predict and quantify, and has many characteristics that are affected by weather conditions, geology, and terrain, which are difficult to artificially control.

On the other hand, pollutants include particulate matter having a specific gravity greater than that of water, particulate matter having a specific gravity less than the specific gravity of water, substances moving in a dissolved state of water, substances moving together in a colloidal state, organic matters, and the like. There are many varieties, and unlike contaminated water from point sources, contaminated water from nonpoint sources can contain all such contaminants. Here, the particulate matter having a specific gravity larger or smaller than the specific gravity of water can be separated using physical precipitation or buoyancy, and in the case of soluble materials and colloidal materials, they are separated by precipitation or flotation by chemical treatment. You can make it. For reference, a method of separating contaminants by filtration or adsorption is also disclosed.

Since the contaminated water generated from the nonpoint source is difficult to identify the contaminants and may contain all kinds of contaminants, the purification device having only a specific purification method may not have an excellent purification rate. Therefore, there is a need for a purification apparatus having various purification methods.

Conventional techniques for purifying contaminated water generated from such nonpoint source include Korean Patent Publication No. 10-0441628 (Invention name: Non-point pollutant treatment method using a cyclone separator and a rotary disk filter, and its treatment apparatus) Or quoting techniques).

According to the cited technology, a sedimentation tank, a storage tank, an inlet pump, a cyclone separator, a rotary disk filter, a metal precipitation tank, a sludge storage tank, etc. are provided in order. According to such cited technology, when the contaminated water is separated from the sedimentation tank and the coarse material having a high specific gravity is moved to the storage tank, the condensed water is sequentially passed through the cyclone separator, the rotary disk filter, and the rapid sedimentation tank according to the operation of the inlet pump. Purified and discharged.

However, the above cited technology has the following problems.

First, according to the cited technology, the inclined tubular screen is provided in the sedimentation tank to separate the suspended solids, but there is a limit in separating all the suspended solids by the inclined tubular screen, and the suspended solids (such as twigs) are not separated. This will interfere with the smooth movement of the contaminated water on the contaminated water flow path leading to the cyclone separator, the rotary disk filter, and the rapid settling tank, or result in poor processing of the device.

Second, according to the cited technology, the baffle retaining wall is provided in the sedimentation tank to separate the particulate matter having a high specific gravity, but the baffle retaining wall loses its function due to heavy rain or rainy season due to rain or heavy rain. If the baffle retaining wall is to maintain its function continuously, it is necessary to have the trouble of removing the particulate matter separated by the baffle retaining wall repeatedly, but the work in the rainy day is not only cumbersome but also waste of manpower.

Third, since the storage capacity of the storage tank becomes smaller as the fine particles are continuously deposited and deposited in the storage tank, it is necessary to take the hassle of removing the precipitate that has been deposited over a period of time.

The present invention has been made in order to solve the above problems, an object of the present invention, when the contaminated water is introduced, the suspended solids are completely separated in two times and then sent to a subsequent treatment process, to separate the sediment to separate It is to provide a contaminated water purification device that does not require any hassle or manpower.

The contaminated water purifying apparatus according to the present invention for achieving the above object is a chamber in which the inlet and the outlet are respectively formed to separate the sediment and the suspended matter from the contaminated water, and the contaminated water is introduced into and discharged from the chamber. A separator having a hydrocyclone separator and a suspended matter separator in order in the direction; A reservoir in which contaminated water from which sediment and suspended matter are separated from the separator is transferred by gravity; A chemical treatment apparatus for adding a chemical to the contaminated water from the reservoir; A first transfer pipe for transferring the contaminated water from the reservoir to the chemical treatment device, among which a first pump is installed; A reaction tank having a reaction space for reacting with the chemical substances added from the chemical treatment apparatus and having a purified water outlet through which purified water is discharged from the reaction space; A storage tank for storing the precipitated material precipitated in the separator and the reaction tank; A second transfer pipe for transferring the precipitated material precipitated in the hydrocyclone separator of the separator to the storage tank, in which a second pump is installed; And a third transfer pipe which transfers the precipitated material precipitated in the reaction tank to the storage tank, in which a third pump is installed. The hydrocyclone separator of the separation device may include a floating material removal opening or an opening, and a radius of a predetermined portion of the side wall may be extended to the outside, so that the contaminated water flowing into the side wall of the separation device may be extended. It is characterized in that it is introduced in the tangential direction to receive a large centrifugal force.

The bottom surface of the reservoir is characterized in that the inclined material precipitated from the contaminated water in the reservoir can be collected at the end side of the first transfer pipe.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment according to the present invention will be described in more detail.

The contaminated water discharge pipe 12c is configured such that one side passes through the contaminated water discharge port 12a-3 to allow the contaminated water treated in the casing 12a to be discharged to the floating material separator 13 side. However, it has a U-shape to drain only the contaminated water from which sediment and suspended matter are separated without disturbing the rotational force of the contaminated water.

The floating material separator 13 defines a separator 13a in which a passage hole 13a-1 through which contaminated water from which suspended substances are separated passes is formed, and a passage hole 13a-1 of the separator 13a. Shielding at intervals, but comprises a shielding film (13b) for moving the contaminated water from which the suspended solids separated to move downwards and then again from the downward direction to pass through the passage hole (13a-1). The suspended solids separator 13 also applies to the inventors of the present application filed in advance (registration number: 10-0464640).

The reservoir 200 passes through the hydrocyclone separator 12 and the floating material separator 13 in order in the chamber 11 of the separator 100 and is discharged through the outlet 11b of the chamber 11. Contaminated water is stored. And the bottom surface of the reservoir 200 is inclined so that the precipitated material precipitated from the contaminated water in the reservoir 200 can be collected at the end side of the first transfer pipe (400).

In the chemical treatment apparatus 300, chemicals (eg, NaHO, Alum, etc.) may be added to the contaminated water from the reservoir 200, and then discharged to the reaction tank 500.

The operation state of the contaminated water purifying apparatus configured as described above will be described with reference to the flowchart and reference diagram of FIG. 4.

1. Separation of sediment and suspended solids <S401>

The contaminated water introduced into the casing 12a through the inlet 11a of the chamber 11, more precisely, through the contaminated water inlet pipe 12b of the hydrocyclone separator 12, is the contaminated water inlet 12a-2. After being introduced into the expanded side wall 12a-1, it descends downward while rotating along the side wall as shown in FIG. 5 with a large centrifugal force. At this time, the particulate matter greatly affected by the centrifugal force moves downward through the side wall while sticking to the side wall side, and settles to the bottom of the casing 12a, and the floating material having a small specific gravity floats upward. Subsequently, the contaminated water moved downward while the sediment is separated is moved upwards on the vertical center line of the casing 12a by the ascending swirling vortex as shown in FIG. It is discharged to the floating material separator 13 side through the contaminated water discharge pipe 12c.

On the other hand, the contaminated water discharged to the floating material separator 13 side is blocked by the shielding film 13b and does not immediately pass through the passage hole 13a-1 of the separator 13a, as shown in FIG. After moving in the direction to exit through the through hole (13a-1), at this time, the floating material that is not separated in the hydrocyclone separator 12 is separated again while floating in the upward direction.

As such, almost all particulate suspended solids (such as tree branches) are separated from the separating apparatus 100, which may be caused by the particulate suspended solids on the contaminated water moving path that is subsequently moved to the treatment process. Remove it. Of course, the liquid suspended solids (oil, etc.) are also largely separated together.

2. Storage <S402>

The contaminated water discharged through the outlet 11b of the chamber 11 after passing through the floating material separator 13 is temporarily stored in the reservoir 200 installed thereafter.

Here, fine particulate matter (mud, etc.) that could not be separated in the hydrocyclone separator 12 may be precipitated, and these precipitated materials are referred to in FIG. 9 because the bottom surface of the reservoir 200 is inclined. The first transfer pipe 400 is collected toward the end of the end.

3. Addition of chemicals <S403>

On the other hand, the contaminated water stored in the reservoir 200 is moved to the chemical treatment apparatus 300 by the operation of the first pump 410, the chemical is added to the chemical treatment apparatus 300. At this time, as shown in Figure 9, due to the suction force of the first pump 410 is also drawn to the bottom surface of the reservoir 200 because the sediment material precipitated on the bottom surface of the reservoir 200 is moved together. Precipitates can be almost removed.

4. Chemical reaction and purification water discharge <S405>

Subsequently, the contaminated water to which chemicals are added in the chemical treatment apparatus 300 is moved to the reaction tank 500, and while the chemical reaction occurs in the reaction tank 500, fine precipitates are reprecipitated again. At this time, since the precipitate and suspended matter is further generated by a chemical reaction occurring in the reaction tank 500, as shown in Figure 10, the precipitate is precipitated and deposited on the bottom of the reaction tank 500, purified water Above, the suspended solids will drift. The purified water located between the suspended solids and the sediment is to be discharged to the outside through the purified water discharge port (500b) formed on the side.

5. Removal of sediment and suspended solids <S405>

On the other hand, the sediment deposited on the bottom of the hydrocyclone separator 12 and the bottom of the reaction tank 500 is the second conveying pipe 700 and the third in accordance with the operation of the second pump 710 and the third pump 810. Moving to the storage tank 600 along the transfer pipe 800, the administrator later opens the cap 600b to deposit the sediment deposited in the reservoir 600, as shown in Figure 11 to remove the pollutants 600a By removing through, the sediment separated by each device is finally removed.

In addition, the suspended solids separated by the hydrocyclone separator 12 and the suspended solids separator 13, and the suspended solids suspended in the reaction tank 500 may be used for the types of suspended solids through the suspended solids removal ports 12a-4 and 500d. Therefore, it is removed by garden cloth (such as tree branches) or by an adsorbent (oil or the like).

Although the above-described embodiments have been mainly described in terms of precipitates and suspended solids and pollutants that are easily treated chemically, it is obvious that other purifiers (filters, adsorbers) may be further configured according to the implementation.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings, but the above-described embodiments have been described by way of example only, and the general knowledge in the technical field to which the present invention belongs. The person having ordinary skill in the art can easily carry out other forms of the present invention within the same scope as the above embodiments, or can implement the invention in an equivalent area to the present invention only by the description of the embodiments of the present invention. Therefore, the present invention should not be construed as being limited only to the above-described embodiments, but should be construed to include the contents described in the following claims and their equivalents.

As described in detail above, according to the present invention, when contaminated water is introduced, the suspended solids are almost completely separated in two times, and then sent to a subsequent process, whereby particulate matter is transferred to the contaminated water moving path during the subsequent process. It is possible to prevent the occurrence of problems caused by the suspended solids, there is a convenience to treat the sediment precipitated from the hydrocyclone separator, reservoir, reactor in a storage tank at once.

In addition, the bottom surface of the reservoir is inclined to pump fine particulate matter that may be deposited on the bottom of the reservoir so that it can be settled again in the reaction tank after being sent to the subsequent treatment process, thereby maintaining a low capacity of the reservoir. There is no need to go through the work.
