Japanese Patent No. 15316 discloses that a cylinder for discharging solid matter such as earth and sand accumulated near the center of a rotating cylinder at the bottom of a processing tank is provided integrally with the rotating cylinder. We propose a solid-liquid separator that can be used. But,
In the solid-liquid separator, during continuous use, for example,
If maintenance or inspection of the pump for discharging solids contained in the cylinder becomes necessary, the rotating cylinder and the cylinder for discharging solids are integrated. In addition, there is a trouble that the liquid to be treated in the processing tank must be drained and then maintenance and inspection work must be performed. For this reason, normal drainage or treatment work must be stopped during maintenance and inspection work, which may cause public problems such as drainage of bad water in highly public water treatment facilities. Was. Further, in the solid-liquid separation device disclosed in Japanese Patent Application Laid-Open No. 1-215316, a pump or a spiral blade built in a cylinder for discharging solids (hereinafter referred to as a discharge cylinder) is used to remove solids. In the case of spiral blades, solids cannot be efficiently discharged unless the discharge cylinder is rotated much faster than the rotating cylinder, or a pump for discharging solids is installed inside the discharge cylinder. However, there are practical problems such as the inability to take out and install the pump for repair and the like during operation and the problem of electrical contacts during operation. Therefore, an object of the present invention is to further improve the water treatment apparatus proposed by the present inventor without impairing their advantages, and integrate the water treatment apparatus with pump equipment as needed to integrate the water treatment apparatus near the upper and lower centers of the cylinder. It is an object of the present invention to provide a novel water treatment apparatus which can easily remove and treat waste soil and suspended matter, and further facilitate maintenance and inspection work during use.

もよい。The rotating cylinder 2 is driven by driving sources 3 and 3 'such as motors attached to a support 7 fixed to the processing tank 1. The illustrated example is the shaft 3 of the motor 3, 3 '.
A drive gear 32 is provided at the end of the cylinder 1 and meshes with a band gear 33 provided around the outer wall surface of the cylinder to rotate the cylinder 2 at an appropriate speed. A flange 34 for supporting the cylinder 2 is provided on the outer side of the upper part of the cylinder, and the cylinder 2 is rotatably suspended by the motors 3 and 3 'via friction reducing means such as a ball bearing 35. In this case, when there is a possibility that the entire processing tank is tilted due to land subsidence or the like, it is preferable to provide an adjustment mechanism for maintaining the rotating cylinder vertically. In the illustrated example, the rotational force of the motor is transmitted to the rotary cylinder 2 by a gear. For example, the gear is replaced with a hard rubber or a hard rubber coating, and the cylinder is rotated by frictional force with the outer surface of the cylinder 2. Alternatively, the cylinder 2 may be rotated by other means.
In FIG. 1, two similar motors 3, 3 'are shown on the left and right. However, as long as the rotating cylinder 2 is maintained substantially vertical, one motor may be used. A method of making the rotating cylinder 2 rotatable without using the center of the rotating cylinder 2 includes, for example, a similar flange (not shown) inside the upper end of the cylinder 2 or inside the middle stage.
May be provided, and the cylinder 2 may be suspended from the support 7 so as to freely rotate, or may be rotatably supported by an arm (not shown) extending from the bottom of the processing tank 1 or the wall of the processing tank 1. Good.

However, this is not essential, and when the rotating cylinder 2 does not sway, or when other means are used. If the lateral movement is prevented by the method, the lateral displacement means 8, 8 'as shown in the figure is unnecessary. A sand passage 9 is formed substantially at the center of the rotary cylinder 2, and the earth and sand 10 is discharged together with a part of the treated water by a pump or the like (not shown), and collected and disposed of in a sand reservoir (not shown). As shown in FIG. 1, the sand removal path 9 is provided independently and independently of the structure of the rotary cylinder 2 and there is nothing at the center of the rotary cylinder. When maintenance or inspection is required, it is possible to easily inspect the inside or the like by pulling up only the facility for removing the accumulated matter such as the sand drainage path 9. In FIG. 1, a pipe 11 provided on the side of a facility for removing accumulated substances such as a sand removal path 9 is connected at its end to a compressor or the like for supplying compressed air.
Compressed air can be introduced through 1 to aid in soil removal. The above is an example, and it is natural that the removal of the earth and sand may be performed by another method. Also, as shown by a chain line in FIG. 1, this sand removal path 9 is disposed at the lower end near the water surface, preferably slightly below the water surface, to remove suspended matters accumulated at the center of the rotary cylinder 2. Can also be used.

に処理される。The rotary cylinder 2 is preferably made of stainless steel or a metal subjected to antiseptic treatment in consideration of strength, antiseptic property and the like. The wall surface of the rotating cylinder 2 is usually smooth, but a large number of holes and grooves (not shown) are formed on the wall surface.
May be provided to improve the frictional force with the water to be treated. When the rotating cylinder 2 is rotated in the same direction in the processing tank 1 by the driving sources 3 and 3 ′, the water flow is accelerated by the frictional force between the rotating cylinder 2 and the water to be treated, and the flow velocity becomes closer to the wall surface of the cylinder 2. Becomes large, and the flow velocity of the water to be treated decreases as it approaches the wall surface of the treatment tank 1. With this forced primary flow,
The suspended matter 14 existing on the surface of the treated water is attracted to the vicinity of the rotating cylinder 2, passes through the weir 12 provided inside the upper part of the rotating cylinder 2, and is accumulated in the suspended matter reservoir 13. Fine algal debris, plankton, oil droplets, etc. suspended or emulsified on the surface of the water together with the suspended matter 14 by the forced secondary flow by the rotating cylinder 2 are drawn to the rotating cylinder 2, and similarly passed over the weir 12. Is accumulated in the floating material reservoir 13. It is preferable that the weir 12 be allowed to move up and down to overflow in case the water level falls below the weir. On the other hand, earth and sand 10 suspended in the water to be treated by the primary flow and the secondary flow of the rotary cylinder 2 are collected at the bottom of the processing tank 1 at substantially the center of the rotary cylinder 2, sucked and removed by the sand removal path 9, and likewise.
