It is preferable that the flow direction of raw water and ozone be opposite to each other by flowing into the 211 and flowing into the second flow hole 221 at the bottom to have a flow flow from the top to the bottom.

This is to increase the residence time of ozone in the ozone treatment chamber 120 to increase the contact time between the raw water and ozone, and at the same time improve the reaction rate between the raw water and ozone, thereby increasing the dissolved oxygen rate of the raw water and improving the sterilization treatment effect. .

On the other hand, in the ozone treatment unit 500, when ozone flowing out from the ozonizer unit 510 is not partially decomposed in the raw water, the undecomposed exhaust ozone may affect the operator. Therefore, a configuration for treating the ozone exhausted from the ozone treatment unit 500 is required, and in the present invention, the ozone treatment means 520 may be configured to treat such ozone.

It may be formed in a rectangular mesh shape on a plane so as to flow uniformly, and the size and number of the through-holes 611 at this time can be set in various ways.

Here, the activated carbon block 610 is formed in a straight line so that the through-holes 611 are aligned over the upper and lower ends, so that when raw water flows along the through-holes 611, flow resistance can be minimized, and this It is desirable to reduce the flow loss and to lower the head loss.

That is, the through hole 611 is preferably formed in a straight line so as to be parallel to the flow direction of the raw water. In the drawings, when the flow direction of raw water in the second adsorption chamber 130 is a vertical direction from a downward direction to an upward direction, the through hole 611 may be formed in a vertical direction corresponding to the flow direction of the raw water. have.

Here, as the mesh member, various mesh members such as known stainless roll mesh and stainless wire mesh are applicable.

The support frame 621 may be configured in various sizes to accommodate one or a plurality of activated carbon blocks 610 therein. That is, the support frame 621 is configured to accommodate all of the activated carbon blocks 610 in the second adsorption chamber 130 , or can be accommodated by dividing the activated carbon blocks 610 into a plurality.

In addition, the support frame 621, although not shown, may be configured to form an opening/closing part (not shown) so that the activated carbon block 610 can be easily replaced therein.

Hereinafter, with reference to FIG. 13 will look at the operation of the composite filtration device according to an embodiment of the present invention.

Referring to FIG. 13 , first, the filtration tank 100 includes a first adsorption chamber 110 , an ozone treatment chamber 120 , and a second adsorption chamber by a first bulkhead plate 210 and a second bulkhead plate 220 . (130), respectively.

And the raw water introduced from the first adsorption chamber 110 to the lower inlet 102 flows from the lower part to the upper part and flows to the ozone treatment chamber 120 through the first flow hole 211, and the ozone treatment chamber ( The raw water introduced into the first flow hole 211 of the upper part from 120) flows from the upper part to the lower part and flows to the second adsorption chamber 130 through the second flow hole 221, and the second adsorption chamber 130. The raw water (purified water) that is introduced into the second flow hole 221 and flows from the lower part to the upper part is discharged through the outlet 103 of the upper part.

In this way, in the process of sequentially passing through the first adsorption chamber 100 , the ozone treatment chamber 120 and the second adsorption chamber 130 , the raw water is mainly contaminated with water through biological treatment and adsorption in the first adsorption chamber 110 . Turbidity, which is the cause, is primarily treated, sterilized by ozone in the ozone treatment chamber 120, and desorbed biofilm and microturbidity-inducing substances are adsorbed and residual ozone is decomposed through activated carbon in the second adsorption chamber 130. .

In detail, first, in the first adsorption chamber 110 , the raw water is biologically treated while in contact with the adsorption medium 410 in which the incoming raw water is floating, and more effective biological treatment is performed through the stirring device 420 .

Next, in the ozone treatment chamber 120, ozone is supplied to the raw water that has been primarily water-treated by the filtration unit 400, so that the raw water is treated with water as well as a water treatment to increase the dissolved oxygen rate in the raw water. , the raw water flows in the opposite direction to the ozone flow direction in the ozone generator unit 510, thereby improving the treatment efficiency by ozone.

The raw water passing through the ozone treatment unit 500 finally passes through the activated carbon block 610 to adsorb fine turbidity-inducing substances and decompose residual ozone.

According to the above, the composite filtration device 700 of the present invention includes biological treatment and adsorption by the filtration unit 400 , sterilization and residual ozone damage by the ozone treatment unit 500 , and pollutants by the adsorption unit 600 .

By making it possible, high pumping pressure for circulation is unnecessary, and the loss head can be lowered, thereby reducing equipment cost and maintenance cost.

In addition, in the composite filtration device 700 of the present invention, the water treatment by the biofilm of the adsorption media 410 constitutes a high specific gravity, and since the physical filtration is a part of the method of collecting the biofilm itself, physical filtration ( Filtration due to particle size difference) has a small specific gravity. Therefore, in the composite filtration device 700 of the present invention, clogging does not occur during physical filtration and there is no need for backwashing accordingly, and it is possible to reduce the burden of sewage inlet construction, in areas where discharge is not possible and sewage pipes. It can be easily used in areas where there is no such thing.

In addition, in the composite filtration device 700 of the present invention, as the biological filtration of the adsorption media 410 proceeds, the biofilm becomes thick, and the thickened biofilm naturally occurs by agitation-circulation-collision of the adsorption media 410 . Desorbed, the biofilm thus desorbed is adsorbed to the activated carbon block 610 of the adsorption unit 600 and treated.

On the other hand, the composite filtration device 700 of the present invention is to be installed in a hydroponic facility including a water play facility, and the characteristics of water treatment for a water play area are that the use cycle is about 2 months a year, the water quality of the raw water is constant, Considering that the substances to be filtered are foreign substances (BOD-causing substances, nitrates, ammonia, etc.) that have not been filtered by the pre-filtration filter, dust from clothes, and soil or sand from shoes, the adsorption media (410 ) may need to be replaced, and in this case, the adsorption media 410 may be taken out from the first adsorption chamber 110 and washed with high-pressure water.
