Further, a negative electrode portion 7 is connected to the center cylinder 4. Therefore, the cylindrical portion 21 and the ion generating metal 22 are negatively charged when energized.

Next, the foreign matter removal and sewage purification action by the foreign matter removal water purification device 1 in the present embodiment will be described. Sewage containing foreign matter is removed from the introduction pipe 9 by the foreign matter removal water purification device 1
Is introduced into the body 2 </ b> B of the hollow outer cylinder 2. In some cases, the on-off valve 13 is opened and the compressed air is introduced from the air introducing means 12 in a state of being mixed with the sewage. Thereby, the introductory introduction force of the sewage is increased, and the separation of the foreign matter can be performed more effectively. Since the introduction pipe 9 is connected to the body 2B of the hollow outer cylinder 2 in a tangential direction, the sewage introduced into the hollow outer cylinder 2 swirls in the body 2B. As a result, a negative pressure is generated at the center of the hollow outer cylinder 2, and sewage is introduced between the inner cylinder 3 and the center cylinder 4. Since the inner cylinder 3 is positively charged and the central cylinder 4 is negatively charged, a potential is applied to the sewage, the clusters of water in the sewage are miniaturized, and the foreign substances adhering to the water are mixed with water. The hollow outer cylinder 2 is separated and is guided downward by the influence of the centrifugal force due to the rotation and its weight, moves to the tapered portion 2A side of the hollow outer cylinder 2, is discharged from the foreign matter discharge section 16, and is processed by the foreign matter processing means 17.

On the other hand, the sewage from which the foreign matter has been separated enters the center cylinder 4 through the elongated hole 23 of the center cylinder 4, and at this time, it is more strongly affected by the potential and becomes fine clusters, and the filth in the sewage becomes the center. The water is purified while remaining on the outer side of the cylindrical body 4, becomes purified water, and is introduced into the central cylindrical body 4. In this case, the purified water is sterilized by touching the ion generating metal 22. Bacteria and purified water are supplied to a purified water discharge pipe 5 inserted in the central cylinder 4.
A biological filtration means 15 using bacteria or the like is provided if necessary, whereby the degree of purification can be further improved. In addition, when the water reforming material is filled in the central cylindrical body 4, the purified water is further purified and activated by this. However, even without the water modifying material, the sewage is sufficiently purified and discharged. You. When the backwashing means 14 is attached to the purified water drainage pipe 5, backwashing of the inside of the central cylindrical body 4 and the water reforming material is performed.

Gases and air are generated in the foreign matter removing and purifying apparatus 1 during the above-mentioned sewage purifying operation, and these are discharged to the outside through exhaust holes 18 and 19 provided in the upper lid 10. Thereby, the pressure in the foreign matter removing and purifying apparatus 1 is constantly maintained at a constant pressure state, and the above operation can be performed smoothly. The oil contained in the sewage pools on the upper side, is discharged to the outside via the drain pipe 8, and is appropriately treated.

Although the sewage is generally at room temperature, in the case of a high temperature body, heat exchange is performed by a heat exchange means (not shown) attached to the hollow outer cylinder 2. When the high-temperature sewage becomes low in temperature due to heat exchange, the separated foreign matter becomes sticky, easily adheres to the inner wall, and the foreign matter is more effectively separated and removed.
