Therefore, recently, a method of separating and removing the suspended matter in the waste liquid by a hollow fiber type filter using a hollow fiber membrane filter has been adopted. In a nuclear power plant, a large amount of water is processed, and in order to reduce radiation, the equipment area of a filter device is limited, and a long filter is generally used. When the long hollow fiber type filter is used under external pressure, the amount of filtered water hardly increases even if the length of the filter is increased due to the resistance of water flowing in the hollow fiber. In order to solve such a drawback, in JP-A-60-206405, both end portions of the filter hollow fiber are opened, a water collecting pipe is inserted inside the filter, and a water collecting chamber is provided under the filter. Then, a method has been proposed in which the filtered water taken out to the lower part of the filter is collected in a water collecting chamber, and further, it is drawn out to the upper end of the filter through a water collecting pipe to lower the filtration resistance in the hollow fiber. In addition, since nuclear power plants contain radioactive suspensions, it is necessary to regularly perform air backwashing and air scrubbing to drop the suspensions adhering to the outer surface of the hollow fiber membranes and take them out of the system. There is. However, when the filters are connected in multiple stages in series, it becomes very difficult to introduce air for air scrubbing. For example, in JP-A-60-206415, although a pipe for introducing air is provided around the water collecting pipe in the filter with a double pipe and a spacer is provided at a connecting portion of the filter, a cross-shaped water intake hole and water intake are provided. Air holes have to be provided where they do not intersect the holes, and the air holes must be sealed, which makes the filter complicated and makes it difficult to assemble and inspect the filter. Therefore,
It has been desired to develop a long hollow fiber type filter in which scrubbing air can be easily introduced and which is connected in multiple stages in series. The present inventors have previously proposed Japanese Patent Application No. 61-93437 and Japanese Patent Application No. 62-3474, and have attempted to develop this point. However, this time, the present invention is further proposed.

When the filtration differential pressure of the hollow fiber type filter exceeds a certain pressure,
In order to remove metal colloid etc. adhering to the hollow fiber membrane,
Filtering is stopped and backwashing or air scrubbing is performed. That is, backwashing in which air is introduced from the air introduction pipe (18) provided in the filtrate take-out pipe (13) to push out the water accumulated above the partition plate (2) in the pressure vessel (1), or pressure Air is introduced through an air introduction pipe (15) provided below the container (1). The air that has entered from the air introduction pipe collects in the skirt-shaped recess (6) provided in the lowest filtration unit (A), and the air is slit (7) and air introduction hole (8),
Or, further, through the air distribution holes (19) of the partition plate (20) (Fig. 2), enter the lowermost filtration unit (A) and rise along the hollow fibers (10) in the filtration unit. Perform air scrubbing to vibrate the hollow fiber. The rising air is extracted from the raw water supply port (17) at the upper part of the filtration unit, collected in the upper skirt-shaped recess (6), and used again for air scrubbing of the upper filtration unit. In this way, air scrubbing of each filtration unit is performed from the bottom to the top. The air discharged from the hole (17) of the uppermost filtration unit is discharged to the outside of the system from the air vent (21) provided above the pressure vessel.
