In this embodiment, at least one filter medium of a fixed porous filtering media and a fluidized media is filled in the first-stage water purification unit and the second-stage water purification unit. This will be described with reference to Figs. 13 and 14. Fig.

FIG. 13 is a view for explaining a water purification unit using fluidized bed and fixed bed media according to an embodiment of the present invention, and FIG. 14 is a view for explaining the embodiment of FIG.

Referring to these figures, the first-stage water purification unit is filled with a fixed phase filter medium and a fluid phase filter medium, and the second-stage water purification unit is filled with a fixed phase filter medium. The first stage water purification unit includes a front end portion filled with a stationary phase filter medium and a fluid phase filter medium and a rear end portion filled with a stationary phase filter medium.

Referring to FIG. 14, it can be seen that the first-stage water purification unit and the second-stage water purification unit are filled with the fixed phase media and the fluid phase media.

According to this embodiment, a large amount of microorganisms may be adhered to the stationary phase media and / or the fluid phase media, thereby reducing the BOD material.

According to the present embodiment, the filtration efficiency is increased by using the stationary phase filter media, and the contact efficiency with the river water or the rainwater effluent is increased by the microbial proliferation and flow for removing the BOD material by using the fluid phase filter material .

However, the flow of sewage or rainwater flowing in the water purification unit may be configured as an upward flow or a downflow Do.

As described above, most of the problems occurring in the water treatment system using the existing filter media can be solved.

For example, water treatment systems using existing filter media are perceived as the biggest problem of operation due to sludge or the like during operation. According to embodiments of the present invention, such problems are caused by the presence of porous foamed filter media So that the problem can be solved. When the air is injected from the lower part of the backwash, turbulence is generated accordingly. In the fixed bed media completely filled in the bath, the flow due to the water flow does not occur, but the floating media, (Sludge) adhered to the filter material due to the rotation of the stationary phase filter media, friction, or the like due to the flow. In addition, since the fixed bed material has a very large porosity, the sludge adhered to the bed material can be easily removed from the flow of the water stream.

Meanwhile, in the embodiments of the present invention, the fluid phase media is manufactured to have an independent bubble structure through foaming, so that the apparent specific gravity can be realized in the range of 0.4 to 0.99, It is possible. In addition, according to the embodiments of the present invention, the porous structure can sufficiently maintain a space in which microorganisms can be accommodated, thereby making it possible to maintain a large amount of biomass inside the treatment system, .

Another problem that may occur in the existing water treatment system is that the pollutant load may be concentrated on the inflow portion due to the nature of the horizontal flow, and such a problem can be solved according to the embodiments of the present invention. That is, as mentioned above, the fixed bed material is configured to have a large porosity, so that the contamination load can be easily dispersed from the inflow portion to the inside, so that a uniform pollution load can be reduced in the entire treatment system.

According to one embodiment, in the case where the water purification unit G is configured to include the first stage and the second stage, both the first stage and the second stage purification unit are provided with air supply means at the bottom, (Normal operation), the automatic operation control system 80 receives the measurement result of the dissolved oxygen measurement unit 74 provided in the water quality purification unit G - the concentration of dissolved oxygen - and the concentration of dissolved oxygen The microbes attached to the filter medium may be weakly supplied to such a degree that the microorganisms adhered to the filter medium do not desorb.

In addition, the automatic operation control system 80 is a system that allows the multifunctional bioretention and treatment system using the fluidized bed and fixed bed media according to an embodiment of the present invention to operate at a predetermined time or in a predetermined differential pressure gauge 75 If it is determined that the pressure loss is generated, the backwash operation can be performed. In the automatic operation control system 80, when the backwashing operation (cleaning operation) sufficiently strengthens the aeration strength, the sludge adhered to the filter material can be sufficiently removed. In this case, only air in some of the air supply means It is possible to adjust the aeration strength appropriately. The basic operation of the backwash is to remove the sludge settled in the bottom of the tank during the operation period through the air lift pump (76), pump, etc., and then supply the air for about 5 minutes and then settled for 10 to 30 minutes The sludge settled in the bottom of the tank is discharged to the outside, and the predetermined purifying function can be restored by repeating the operation several times. Such an operation can be performed automatically by the automatic operation control system 80. If the backwash cycle is prolonged, it is possible to proceed manually by the maintenance personnel in consideration of economy. Through the above-described embodiments, it is possible to improve the limitations of conventional storage facilities and to efficiently operate each facility, thereby making it possible to reduce operational costs and provide convenience of maintenance.
