A gate valve 113 is provided on a lower side of a wall surface of the preprocessing needle tucker 110 to open the gate valve 113 when the accumulated foreign substances are discharged to the outside.

An air injector 300 is provided on one side of the pretreatment needle tucker 110 and the end of the air pipe 310 connected to the air injector 300 is disposed on the upper side of the communication hole 121, So that prompt and accurate backwashing can be achieved when backwashing.

The purifying space 120 serves to cause the sewage introduced into the pretreatment needle depositing tank 110 to flow gradually into the purifying space 120 through the communication hole 121 to be filtered.

The pretreatment needle set 110 and the purifying space 120 are connected to the purifying space 120 through the purifying space 120. The purifying space 120 includes a purifying part 200 for purifying the inflow water, Through the communication hole 121 formed through the bottom surface of the cleaning space part 120 so that the sewage water flows into the purification space part 120.

The purifying unit 200 is installed inside the purifying space unit 120 to purify the sewage introduced into the purifying space unit 120.

The purifying unit 200 includes a buoy 210 floated on the upper surface of the inflow sewage, a filter medium 220 for substantially purifying sewage water, and a filter 220 connected to the buoy 210 to selectively compress the filter medium 220 And compression means (230).

The buoy 210 is formed of a material floating on the upper surface of the sewage, or it is made to float on the upper surface of the sewage by filling air therein. The buoy 210 has a volume at which a buoyant force capable of moving a moving plate 232 As shown in FIG.

The filter material 220 is formed in the shape of spherical granules so that the degree of purification of the sewage water is changed according to the gap between the filter materials 220. When the gap between the filter material 220 and the filter material 220 is small, The foreign matter is filtered. On the contrary, when the gap between the strip 220 and the filter 220 is large, only a relatively large foreign matter is filtered.

The compression means 230 includes a circulation induction plate 231 fixed at a predetermined height of the purification space portion 120 below the buoy 210 and having a plurality of flow holes 231a penetrated therethrough, A moving plate 232 having a plurality of flow holes 231a formed therein so as to be able to move upward and downward in the purifying space 120 of the purifying space unit 120 and having one end fixed to the buoy 210 and passing through the circulating induction plate 231, And a bar 233 coupled to the moving plate 232.

The circulation induction plate 231 is fixed at a predetermined height of the purification space part 120 and restrains the movement of the filter material 220 when the buoy 210 is floated by the sewage introduced into the purification space part 120, 220 to be compressed.

For this, a plurality of flow holes 231a formed to have a size smaller than the size of the filter media 220 are formed in the plate surface of the circulation inducing plate 231 so as to pass the sewage but not the filter material 220.

The plate 220 of the circulating induction plate 231 is pressed against the circulating induction plate 231 during the washing of the filter media 220 while injecting air while increasing the compressive force between the filter media 220, It is preferable that the angle is changed so that the circulation is briskly formed.

The moving plate 232 is disposed below the circulation induction plate 231 and movably installed along the height direction of the purification space unit 120 so that the circulation induction plate 231 is lifted up by the sewage, So as to compress the filter media 220.

Like the circulation induction plate 231, the moving plate 232 is preferably formed with a plurality of flow holes passing through the sewage but not allowing the filter media 220 to pass therethrough, And is connected to the buoy 210 by the buoy 210.

The compression means 230 having such a configuration is provided for each of the plurality of communication holes 121 formed in the boundary region between the preprocessing needle room 110 and the purification space portion 120 and is provided in the purification space portion 120 with a plurality of compressions The means 230 is more effective in enhancing the purification efficiency of the sewage. For this purpose, the purification space unit 120 is constituted by a unit module, and can be installed easily by increasing or decreasing the unit module according to the capacity .

6, in the case of an excellent soil purification apparatus according to another embodiment of the present invention, a circulation induction plate 231 is fixedly disposed at a predetermined height of the purification space 120, and a fixed circulation induction plate 231b And a moving circulation induction plate 231c disposed so as to be able to ascend and descend below the fixed circulation induction plate 231b and is provided with a filter material 221 disposed between the moving plate 232 and the moving circulation induction plate 231c ), The moving circulation induction plate 231c and the filter medium 222 disposed between the fixed circulation induction plate 231b may be formed to have different particle sizes or donations.

In addition, the filter medium 220 may be a general high-elasticity filter medium for removing contaminants contained in sewage, but may further include a special filter medium capable of adsorbing heavy metals contained in contaminants in addition to the high- It is a matter of course that applicable filter material is also applicable.

A separate holding space 400 is provided in front of the space forming part 100 along the direction in which the sewage flows in. The sewage flows into the holding space 400 and stays for a predetermined time, To flow into the flow space portion 110 through the inflow pipe 112 connected to the flow path portion 110.

This is because the foreign substances included in the sewage introduced at the early stage after storm surge are firstly deposited on the bottom surface of the retention space unit 400 and then introduced into the pretreatment settling tank 110 side.

A separate gate valve (410) is disposed on one side wall of the holding space (400) to allow the foreign substances to be discharged to the outside, Respectively.

A filtered water storage part 500 provided with a gate valve 510 is provided behind the space forming part 120 through which the sewage flows out to a part of the purified sewage so that a certain level is formed and stored.

This is for backwashing the filter media 220 using the filtered water stored in the filtered water storage part 500 at the time of backwashing the filter media 220 and to allow the filtered water to be discharged to the filter material 220 only when backwash is necessary A gate valve 510 is installed at one side of the filtered water storage part 500.

The process of purifying sewage and backwashing the filter media using the excellent toil purification apparatus according to the present invention having such a configuration is as follows.

When a large amount of sewage having a high degree of contamination due to rainstorms flows into the interior of the retention space 400, the interior of the retention space 400 is gradually filled with water from the bottom of the retention space 400, When the water level is higher than the inlet, the sewage flows into the interior of the pretreatment needle-sink 110 through the inflow hole 111 while passing through the inflow pipe 112.

At this time, the heavy foreign substances contained in the sewage water accumulate on the bottom surface of the retention space part 400 while staying in the retention space part 400 until the sewage is filled in the retention space part 400 at a certain level or more. It is removed from sewage.

The sewage introduced into the pretreatment needle depositing tank 110 is secondarily deposited and removed from the sewage until the sewage is filled at a predetermined level in the pretreatment needle depositing tank 110. If the sewage is continuously supplied, The sewage flows into the purification space part 120 through the communication hole 121.

Foreign matter deposited on the bottom surface of the retention space 400 and the pretreatment needle bearer 110 is discharged to the outside by closing the gate valves 113 and 410 when the sewage is purified and the water level is lowered .

When the sewage is continuously introduced into the purification space part 120 through the communication hole 121 and the water level of the sewage is increased in the purification space part 120, the buoy 210 floats up to the surface of the sewage, The moving plate 232 is lifted along the buoy 210.

As the moving plate 232 is moved upwards, the filter media 220 disposed between the circulation plate 233 and the moving plate 232 are compressed to narrow the gap between the filter media 220, The filtration water is partially filtered by the filtered water storage unit 500 and the remaining filtered water is discharged to the river to complete the purification.

Meanwhile, the process of backwashing the excellent soil purification apparatus is as follows.

When the air injector 300 is driven, the air generated in the air injector 300 passes through the air pipe 310 and flows into the purification space part 120 through the communication hole 310.

The filter medium 220 flows between the circulation inducing plate 231 and the moving plate 232 by the air introduced into the purifying space 120 and the foreign matter adhered to the filter medium 220 is removed, As shown in FIG.

Then, the gate valve 113 provided at one side of the preprocessing settling tank 110 is opened to discharge the foreign matter adhering to the filter media 220 to the outside, thereby performing a primary backwash.

Thereafter, the gate valve 510 provided in the filtered water storage part 500 is opened to allow the filtered water stored in the filtered water storage part 500 to be ejected toward the filter material 220, So that the backwashing is completed by backing up the filter material 220 more cleanly.

It is to be understood that the scope of the present invention should not be construed as being limited to the embodiments described above, It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
