き出している。(Prior art and its problems) Hollow fiber filters are economical because they have a large membrane area per unit volume, and are used in various fields such as semiconductors, medicine, and food. By reducing the diameter of the hollow fibers, it is possible to increase the number of membranes packed per unit volume, but there is resistance to water flowing through the hollow fibers, so hollow fiber filters with a length of about 1 inch are usually used. There is. However, recently, in nuclear power plants and the like, there is a tendency to increase the length of hollow fiber filters in order to minimize the installation area. The filter used in nuclear power plants is a suspended type filter with external pressure total filtration.
The lower end of the filter is closed and the filtrate is drawn out to the -L end of the filter. Therefore, i+! When the length of the filter becomes longer, the amount of filtrate hardly increases even if the length of the filter is increased due to the resistance of water flowing through the hollow fibers. JP-A No. 60-206415, 'I! r Kaisho 60-2443
In order to solve these drawbacks, No. 05 has one water intake pipe in the center of the filter, a pneumatic feed pipe running parallel to it, and a large number of hollow fibers surrounding the water intake pipe and the pneumatic feed pipe. (Japanese Unexamined Patent Publication No. 60-206415), or by using two or more filtration member units in which hollow fiber bundles are fixed in a U-shape to the inner surface of a nap member, a U-shaped hollow fiber bundle can be obtained. They are arranged to face each other, and one filtrate pipe is arranged in the center or four filtrate pipes are arranged in the four corners (Japanese Patent Application Laid-Open No. 60-244305), and the I! ! Excess water is removed.

が困難である等の問題点があった。However, in this type of system, the number of hollow pipes is extremely small (one or several), and their placement position is limited, for example, only in the center, so the filtration performance of the hollow fiber membrane is good. In this case, it is necessary to increase the diameter of the hollow pipe for extracting the discharged water, which inevitably reduces the number of hollow fibers that can be filled in the filter, resulting in a decrease in filtration capacity. Furthermore, in order to remove attached metal colloid, etc., such a filter periodically performs air backwashing or air scrubbing, vibrates the hollow fibers, and discharges metal colloid, etc. from the system. When the number of filled hollow fibers is increased, the vibration of the hollow fibers decreases even when air backwashing or air scrubbing is performed, and the removal performance of attached metal colloids etc. decreases, and the removal of attached metal colloids etc. There were problems such as metal colloids being caught between the hollow fibers and difficult to extract from the system.

In the present invention, as shown in FIG. 2, thick hollow fibers 11 having an inner diameter of 1 to 5 mm are uniformly dispersed and mixed into the ordinary hollow fibers 10 in a range of 1 to 30% of the total number of hollow fibers. ing. This thick hollow fiber acts as a water collecting pipe while filtering the liquid to be treated.The thick hollow fiber with an inner diameter of 1 to 5 mm mixed in with the normal hollow fiber may be made of the same material as the normal hollow fiber. Even if thin hollow fibers are made thicker in a similar manner, the compressive strength will decrease slightly when used under external pressure.Moreover, hollow fibers related to nuclear power are generally used as microfilters with pore diameters of about 0.05 to 0.3 gm. is used, and the amount of filtrated water decreases in proportion to the membrane thickness, so increasing the inner diameter will lower the flow resistance, but the compressive strength and amount of filtrated water will decrease, so the inner diameter of the hollow fibers to be mixed should be 1 to 5 mm. is preferred. Further, the mixing ratio is preferably 1 to 30%, and if it is less than 1%, the water collection effect is small, and if it exceeds 30%, the membrane area will decrease and the amount of filtrated water will decrease, which is not preferred.
