A submersible pump 5 for sucking sewage from the third side and discharging purified water from the other end 4 side, and a sewage treatment provided on the other end 4 side in the tubular body 2 and configured to allow microorganisms to inhabit. A water purification device having an air introduction means 8 for introducing air into the cylindrical main body 2 provided with an air inlet 7 that opens on the water, and the water purification device 1 is a submersible pump 5. Along with the movement of sewage in the cylindrical main body 2, air is drawn into the sewage in the cylindrical main body 2 from the air introduction port 7 of the air introduction means 8. Hereinafter, each configuration will be described in detail.

  As shown in FIG. 1, the sewage treatment apparatus 1 of this embodiment has a cylindrical main body 2 that is disposed on the bottom of the water and has both ends 3 and 4 opened. This cylindrical main body 2 is formed in a cylindrical body as shown in FIG. 3, and is disposed so as to extend in the horizontal direction at the bottom of the water. One end 3 of the cylindrical main body 2 functions as an inlet for sewage, and the other end 4 functions as an outlet for purified water.

  As shown in FIG. 2, the submersible pump 5 for sucking sewage from the one end 3 side of the cylindrical main body 2 and discharging purified water from the other end 4 side is provided on the one end 3 side in the cylindrical main body 2. Is provided. The submersible pump 5 of this embodiment is configured so that a driving source can be obtained from the water and the driving operation can be performed on the water. As described above, according to the water purification apparatus of the present invention, since the sewage flow is formed by the submersible pump, it is possible to purify the water over a wide range even if it is disposed in a closed water area with less flow, and the water purification is efficiently performed. Can be manufactured at low cost.

  On the other end 4 side in the cylindrical main body 2, a sewage treatment unit 6 configured to allow microorganisms to live is provided. The sewage treatment unit 6 is provided with a large number of carriers 9 serving as microbial habitats, and is configured so that aerobic bacteria and anaerobic bacteria adhere to these carriers 9 and inhabit. And a biological water purification process is performed by the aerobic microbe and anaerobic microbe which inhabit in the sewage treatment part 6, and sewage is purified.

  The carrier 9 disposed in the sewage treatment unit 6 may be any type as long as microorganisms can inhabit it. However, there are many irregularities, a large surface area, and a hollow portion formed inside so that microorganisms can easily adhere. Such as is preferred. For example, as such, those obtained by collecting and solidifying plastic scraps, caps of plastic bottles, etc., or those compressed and coated with a metal wire can be suitably used. In addition to resin materials and metals, materials that do not rot such as stones and fibers are suitable as the constituent material of the carrier.

  The air introduction means 8 is for introducing air into the sewage that is sucked into the cylindrical main body 2 by the submersible pump 5, and this introduction of air promotes the growth of especially aerobic bacteria, and biological water purification. Water treatment can be performed more efficiently by activating the treatment.

  As shown in FIG. 2, the air introducing means 8 of this embodiment includes an air suction device 10 communicating with the submersible pump 5, one end communicating with the air suction device 10 in the cylindrical body 2, and the other end communicating with the floater 11. A tubular body 12 that floats on the water, and an aerated sewage conduction pipe 13 that communicates with the air suction device 10 at one end and communicates with the sewage treatment unit 6 at the other end.

  The air suction device 10 is for mixing air into the sewage flowing from the submersible pump 5, communicates with the submersible pump 5 at one end side to receive the sewage flow, and communicates with the aerated sewage conducting pipe 13 at the other end side. Furthermore, it communicates with the tubular body 12 at the upper part near the center.

  The tubular body 12 is for taking in air from the surface of the water. One end of the tubular body 12 communicates with the air suction device 10 in the cylindrical body 2, the other end floats on the water by the floater 11, and the other end opening is formed. An air inlet 7 is configured. Since the water purification apparatus of the present invention has such a tubular body and employs a structure for supplying air into the cylindrical body from the water, there is no need to inject compressed air into the apparatus in advance, Even when a water purification device is provided, air can be supplied into the cylindrical main body by forming the tubular body longer than the water depth. In addition, although it is efficient and preferable for water quality purification to arrange | position the water quality purification apparatus of this invention to the water bottom which sludge etc. settles, when a sewage layer exists in water, you may distribute in water.

  The aerated sewage conduction pipe 13 is for introducing sewage mixed with air into the sewage treatment unit 6, one end of which communicates with the air suction unit 10 to receive sewage mixed with air, and the other end The sewage that is communicated with the sewage treatment unit 6 and mixed with air is introduced into the sewage treatment unit 6.

The cylindrical main body rotating tool 14 is for rotating the cylindrical main body 2 in the circumferential direction, and as shown in FIG. 1 or FIG. It is comprised with the string-like body made. And it is comprised so that the cylindrical main body 2 can be rotated by pulling up two string bodies of one side from the water, and the inside of the sewage treatment part 6 can be activated more.

Next, the operation (use method) of the water purification device 1 of the present invention will be described.
When using the water purification apparatus 1, as shown in FIG. 1, the cylindrical main body 2 is arranged so as to extend in the horizontal direction at the bottom of the water. Along with this, the other end of the tubular body 12 floats on the water by the buoyancy of the floater 11 and the air inlet 7 is opened on the water. When the submersible pump 5 is driven in this state, the sewage is sucked into the cylindrical main body 2 from one end 3 of the cylindrical main body 2 and flows into the aerator 10 through the submersible pump 5, as shown in FIG. . In the air mixer 10, air follows the flow of sewage and is taken into the sewage from the air inlet 7 of the tubular body 12. Then, the sewage into which the air has been taken in is introduced into the sewage treatment unit 6 through the aerated sewage conduction pipe 13. In the sewage treatment unit 6, biological water purification is performed by the microorganisms living in the carrier 9, and the purified water is discharged from the other end 4 of the cylindrical body 2.

  Thus, since the water purification apparatus of this invention forms a sewage flow with a submersible pump, even if arrange | positioned in the closed water area with few flows, the water quality purification over a wide range is attained. In addition, since a structure for supplying air into the cylindrical main body from the water is adopted, it is not necessary to inject compressed air into the apparatus in advance, and even when a water purification device is arranged on a deep water bottom, By simply forming it longer, air can be easily supplied into the cylindrical main body, and efficient water quality purification becomes possible.
