A hydraulic motor 61 and a rotary shaft 62b having a hollow space connected to the rotary shaft of the hydraulic motor 61 for transmitting the rotational force from the hydraulic motor 61 to the inside of the filter tank 50 and through which purified water passes. The rotary shaft 62b is rotatably inserted into a case (stationary member) 62a having a purified water discharge port, and a rotary joint 62 for transmitting rotational force. A rotary coupler 62c having a hollow space therein and a cylindrical filter cylinder 63 in which a plurality of water passage holes are formed. The connecting cylinder 63a inserted into the hollow space of the rotary coupler is extended from one end of the filter cylinder 63, and the rotation support shaft 63b is extended from the other end. The connecting cylinder 63a is treated water. The rotation support shaft 63b is a closed filter cylinder 63 and a bracket 66d into which the rotation support shaft 63b of the filter cylinder 63 is inserted, and a plurality of latch protrusions 66c are formed on the bracket 66d. A bracket 66d formed circumferentially at a predetermined distance from the center, and a plurality of fiber holders 66a and 66b fixed radially to the rotary coupler 62c and the bracket 66d, respectively, on both sides of the filter cylinder at both ends. Connected to the fiber holders 66a and 66b located by hooks That a plurality of fiber filters 65, connected to the rotational coupler 62c and rotation support shaft 63 b, the holding frame 67 for holding the filter unit while rotatably supporting the rotational coupler 62c and rotation support shaft 63 b, the holding frame 67 In order to enable rotation in only one direction by the action of the bracket 66d and the latch projection 66c, the rotation prevention member 67a is folded by a spring in one direction and the action in the opposite direction is performed. A discharge hose 68 connected to a discharge port formed in the case 62 a of the swivel joint 62 and guiding the processed water to be discharged to the second water pump 70 through the valve 53 outside the filter tank 50. And can be provided. Reference numeral 54 refers to an air safety valve.

ファイバーホルダー６６ａは、それぞれのファイバーフィルター６５の一方の側を保持するために回転カプラー６２ｃへと固定されており、ファイバーフィルター６５を回転させるために回転される。ファイバーフィルター６５が回転するとき、回転力が、ファイバーフィルター６５から、それぞれのファイバーフィルター６５の他方の側を保持しているファイバーホルダー６６ｂへと加えられる。したがって、ブラケット６６ｄのラッチ突起６６ｃが回転阻止部材６７ａによる掛かる作用を受けているとき、ファイバーフィルター６５の回転が制限され、このことが、フィルターユニットの一方向回転を助けるように機能する。 The fiber holder 66a is fixed to the rotary coupler 62c to hold one side of each fiber filter 65 and is rotated to rotate the fiber filter 65. As the fiber filters 65 rotate, a rotational force is applied from the fiber filters 65 to the fiber holders 66b holding the other side of each fiber filter 65. Therefore, when the latch protrusion 66c of the bracket 66d is subjected to the action applied by the rotation preventing member 67a , the rotation of the fiber filter 65 is limited, and this functions to assist the one-way rotation of the filter unit.

上述のとおり、モーター６１を動作させてファイバーフィルター６５を回転させてねじりつつ、第２の水ポンプ７０が、浄化された水をフィルター筒６３へと送るために運転される。その結果、汚水が上述のとおり回転力によってねじられた状態のファイバーフィルター６５を通過するとき、汚泥が汚水から分離され、ろ過された汚水が外筒６４およびフィルター筒６３の水通過孔を通過するとき、汚泥が汚水からさらに分離される。 As described above, the second water pump 70 is operated to send the purified water to the filter cylinder 63 while operating the motor 61 to rotate and twist the fiber filter 65. As a result, when the sewage passes through the fiber filter 65 twisted by the rotational force as described above, the sludge is separated from the sewage, and the filtered sewage passes through the water passage holes of the outer cylinder 64 and the filter cylinder 63. When the sludge is further separated from the sewage.
