The ejection opening 42a is formed along the longitudinal direction of

In this case, as shown in FIG. 2, the outlet pipe 38 and the inlet pipe 42 of the aeration tank 30 are connected to the lower portion of the aeration tank 30, and the mixing injection means 50 will be described below. Since the aeration liquid is supplied by the pumping unit 52, the filtration tank 40 is arranged at the top of the aeration tank 30, that is, arranged side by side in the direction of gravity, thereby minimizing the installation space by increasing various space structures and increasing space efficiency. Can,

Therefore, it is possible to reduce the installation space for the treatment device in the present invention to increase the space efficiency, and also by adding only the filtration tank 40 to the existing equipment can be used as it is, existing facilities can be economically reduced effect of users' desire Can be satisfied.

In addition, the membrane module 44 is connected to the upper portion of each ejection opening 42a and formed in parallel to the direction of gravity, and the individual filter body 46 having the inlet portion 46a at the lower portion is formed.

And a plurality of split slots (46c) for and a fiber bundle (46d) formed in parallel to the direction of gravity on the fixture (46b), to separate the individual filter body (46).

That is, a circular fixing body 46b is formed at an upper portion of the jet port 42a, and an inlet for accommodating aeration liquid flowing into the jet port 42a through the inlet pipe 42 is formed at the bottom of the fixing body 46b. A portion 46a is formed, and the split slot 46c is formed through the fixture 46b to allow the aeration liquid to flow upward through the inlet portion 46a.

In addition, the fiber bundle 46d is formed in the upper portion of the fixing body 46b in parallel to the direction of gravity, thereby separating the individual filter bodies 46 to form a membrane.

Therefore, the individual filter medium 46 is arranged above the outlet 42a along the longitudinal direction of the inlet pipe 42, each of the individual filter medium 46 is connected to a rack (not shown) one Membrane module 44 is formed, and thus formed membrane module 44 is arranged in a predetermined number inside the filtration tank 40 to filter the aeration liquid so that the treated water can be supplied through the transfer pipe 60. do.

In addition, a storage unit 47 for treating water is formed on an individual filter body 46 of each of the membrane modules 44, and each of the storage units 47 is connected to transfer the treated water to the transfer pipe 60. A supply pipe 48 for conveying is formed.

Next, as shown in FIGS. 1 to 4, the mixed injection means 50 according to the present invention is

A pumping unit 52 for pressurizing and discharging the aeration liquid to the inlet pipe 42 of the filtration tank 40 through the outlet pipe 38 of the aeration tank 30, and the outlet 42a of the inlet pipe 42. It is connected to the, supplying the pressurized air to the aeration liquid pressurized by the pumping unit 52 to form a jet stream mixed with air, it is supplied through the electric field of the individual filter body 46 of the membrane module 44 And an air discharge part 54 for maintaining a uniform concentration of the aeration liquid.

That is, the membrane module 44 is composed of a plurality of individual filter bodies 46, the aeration liquid is formed in the individual filter body 46 through the split slot 46c formed in the fixed body 46b. 40), in this case, to supply the pressurized air from the air outlet 54 to prevent contamination of the membrane module 44,
