In the drawings, reference numerals 232 and 241 denote handles fixed to the cover A 230 and the cover B 240, respectively.

Each member of the filtration unit 600 of the present invention uses a stainless steel and a synthetic resin that is corrosion-resistant material.

In addition, the filtration unit 600 is manufactured so as to have a treatment capacity of 10M ³ / DAY, for example, one or two or more are installed as necessary. 2 illustrates a form in which three filtration units 600 are installed. However, there is no reason to limit the treatment capacity and the installed quantity of the filtration unit 600.

In this way, the noise-free hollow fiber membrane sewage treatment apparatus of the present invention can complete the facility only by depositing the filtration unit 600 inside the aeration tank 3.

The aeration tank 3 is installed in a suitable size according to the capacity to be treated, the filtration unit 200 is installed in one or two or more prefabricated according to the size of the aeration tank (3). In addition, even when the filtration unit 600 is installed in the existing septic tank, the upper wall of the septic tank is formed by cutting according to the opening rule size, and the filter unit 600 can be easily deposited and installed through the opening as described above. have.

Wires for supplying power to the submersible pump 400, the submersible blower 500, and the level switch 150 are transferred through the wire connecting pipe 212, and then connected to an operation panel installed in a management room or the like. In addition, the automatic control unit provided in the operation panel enables unmanned automatic operation and is controlled to be operated alternately at predetermined intervals according to the throughput and the concentration of the raw waste water, so that foreign matter filtration and separation processes are alternately performed, and the submersible pump ( 400 and the underwater blower 500 is configured to be controlled by hand as needed for the operation test and repair of the device.

Hereinafter, the operation of the noise-free hollow fiber membrane sewage treatment apparatus of the present invention as follows.

After the treated water is filtered through the screen of the inlet part 1, the coarse suspended matter is introduced into the aeration tank 3 through the flow adjusting tank 2, where appropriate aerobic microorganisms in the aeration tank 3 are promoted as necessary. This can be committed.

Number of processed flows into the aeration tank 3 is connected to the home hollow water tubes 121 by a movable Sikkim to pump the water pump 400 of the filtering unit 200 to the low pressure of 0.3kg / cm ² to 0.6kg / cm ² Since the suction force acts on the inside of the yarn 131, it is sucked into the inside of the hollow fiber 131, and various foreign substances are caught on the surface of the hollow fiber 131. The filtered water collected at 121 is discharged through the discharge tank 4 by the pumping force of the submersible pump 400.

When such a filtration process is performed for a predetermined time, various contaminants are attached to the surface of the hollow fiber 131 of the hollow fiber membrane separator 120. Accordingly, when the suction resistance is higher than a predetermined value, the hollow fiber 131 ), The filtering power is lowered. Therefore, in this case, the operation of the submersible pump 400 installed in the filtration unit 200 is stopped, and the air blower 500 is operated to supply air to the diffuser 320 at a high supply pressure. Air is strongly blown out through a plurality of discharge holes 321 formed in the), and the hollow fiber membrane 130 of the hollow fiber membrane separator 120 is installed in the transverse direction so that the bubble is raised and disposed across the traveling direction of the bubble. Since it is vigorously swinging, foreign matter attached to the hollow fiber 131 is easily separated and collected at the bottom of the aeration tank 3 to be decomposed and removed by aerobic microorganisms.

At this time, if the hollow fiber 131 is made of a hydrophobic material as in the prior art, the dirt attached to the surface of the hollow fiber 131 will continue to stick without being separated, but may be more easily separated because it is made of a hydrophilic material.

In the present invention, since the submersible pump 400 and the submersible blower 500 are installed in the submerged body together with the filtration unit 600, the operation noise of the submersible pump 400 and the submersible blower 500 is increased. This does not occur, and thus it is possible to drive in a very quiet atmosphere.

On the other hand, if you want to simply check and repair the noise-free hollow fiber membrane sewage treatment apparatus of the present invention as necessary, the cover B 240 coupled to the manhole 231 of the cover A 230 is opened.

The apparatus of the present invention as described above has the advantage that the noise-free hollow fiber membrane sewage treatment apparatus can be easily installed by depositing a filtration unit manufactured in a manufacturing plant in an aeration tank of a sewage treatment plant.

In addition, since the hollow fiber membrane separator, the submersible pump, and the submersible blower are installed together to install the filtration unit set, there is no need for a separate machine room, and the installation area is greatly reduced.

In addition, in order to increase the treatment capacity, since the hollow fiber membrane module can be expanded in a stacked type, there is no need for a separate site for expanding the aeration tank, thereby increasing the treatment capacity more easily.

In addition, it can be exchanged in case of partial breakdown, and its material is corrosion-resistant polyethylene and stainless steel, and its life is semi-permanently, and its installation and management cost is low.

Therefore, the above-described apparatus of the present invention is an excellent apparatus that can be very advantageously applied to wastewater treatment facilities as well as sewage.

While the embodiments of the present invention have been described so far, the present invention is not limited thereto, and various embodiments which can be modified and changed within the true spirit and scope of the principles described and claimed are within the protection scope of the present invention. You will have to understand.
