Hereinafter, the brief operation of the nutrient solution purifying apparatus for growing a plant according to an embodiment of the present invention will be described.

6 is a view for explaining the operation of the nutrient solution purifying apparatus for growing a plant according to an embodiment of the present invention.

First, as shown in FIG. 6, the operation of recycling the waste water such as the nutrient solution at the cultivation facility is briefly described as follows. As shown in FIG. 6, the waste water inflow pipe (p1) 21 is connected in a frangible manner and when the waste water is fed by using the pressure feeding pump 8 provided on the wastewater inlet pipe p1, the wastewater is transported along the jetting pipe 21, do.

When the wastewater flows into the main container 1, the microorganisms in the filter 3 (in this case, the sand filter is built in) decompose the organic matter including nitrogen and phosphorus remaining in the wastewater into a certain concentration do.

At this time, the wastewater is jetted at a high pressure even without a separate stirrer, so that turbulence is generated. As a result, the filter is actively moved and more effectively performs purifying action.

The waste water purified by the water spraying means 2 and the filter 3 in the main container 1 moves through the filtration hole 42 and flows into the screen member 4, Is performed.

The foreign matter is filtered and the waste water that has moved into the receiving space of the screen member 4 flows into the inside of the light blocking member 5 through the water inflow hole 511 provided in the upper portion of the light blocking member 5, The sterilizing action by the UV-C light irradiated from the lamp of the sterilizing light source 6 is carried out. At this time, since the light blocking member 5 is formed of a material that can not transmit light, it is prevented from being irradiated with UV-C rays into the main container 1 and the screen member 4, Can be prevented.

Thereafter, the supernatant of the cleaning water, which has been sterilized by the sterilizing device 6, is introduced into the water inflow part 72 of the water discharging member 7 and discharged to the place of use.

If the waste water is discharged to the natural water system, it should not exceed the environmental standard. Therefore, as the filter 3 to remove N and P, The biofilter is filled in the main container 1 and used. When the biofilter is inserted into the main container 1, the microorganisms inhomogeneously decompose organic matter including nitrogen and phosphorus remaining in the wastewater.

At this time, even if a separate stirrer is not provided, the waste water is jetted at a high pressure to generate turbulence. As a result, the biofilter is actively moved and more oxygen is supplied to the biofilter. Therefore, the microbial metabolism is active, . At this time, the sterilizing light source 6 is turned off to prevent microorganisms decomposing organic matter from being killed.

As described above, the wastewater from which organic matter and the like have been removed by the water jetting means 2 and the biofilter in the main container 1 moves through the filtration hole 42 and flows into the screen member 4, The foreign substance removing action is performed.

The foreign matter is filtered and the waste water that has moved into the receiving space of the screen member 4 flows into the inside of the light blocking member 5 through the water inflow hole 511 provided in the upper portion of the light blocking member 5, The supersonic water flows into the water inflow portion 72 of the water discharge member 7 and is discharged, so that it can be discharged to the natural water system.

As described above, the present invention is not limited to the above-described embodiment, but can be applied to the present invention, as described in the claims below, It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
