Description of the Related Art In the present water situation, tap water and well water contain trace amounts of substances harmful to the human body and substances that impair the taste of water due to pollution of rivers and soil. It is well known that this is done. In addition, tap water is required to be added with chlorine for disinfection, and as a result, drinking water is unavoidable with a bleaching odor or musty odor. This tendency is particularly strong in the Kanto and Kansai regions, and it is not welcomed as drinking water as it is, and in order to remove these substances, water purifiers using activated carbon as a filter medium are widely used.

こともできる。A feature of the present invention is to use a module in which a subordinate filter medium capable of adsorbing an odor-causing substance such as 2-MIB is sandwiched between the activated carbon-filled portion and the hollow fiber membrane module. The subordinate filter medium used in carrying out the present invention is not particularly limited, and examples thereof include polydivinylbenzene-based polymers and molecular sheep, and specific examples of the polydivinylbenzene-based polymer include Kao ( There is a musty odor removing polymer manufactured by K.K. Co., Ltd. By using this polymer as a secondary removing material, odorous substances such as 2-MIB contained in raw water can be efficiently adsorbed and removed by 10 times or more of activated carbon. Further, as a specific example of the molecular sheep, there is the molecular sheep 5A, which is a water purifier using a general-purpose strong acidic ion exchange resin as a filter medium when a heavy metal such as lead contained in raw water is used at a high flow rate. 1 compared to
It can be adsorbed and removed more efficiently than 0 times. These subordinate filter media may be used alone or in combination of two or more.

濾材を充填することができる。When these subordinate filter media are sandwiched between the activated carbon-filled portion and the partition between the hollow fiber membrane module, the adsorption efficiency can be maximized. By using this water purifier in which the subordinate filter material is sandwiched between the partition parts, the activated carbon filling part,
It is possible to fill the secondary filter medium without pressing the volume of the hollow fiber membrane module part.

改善された浄水器とすることができる。As described above, by using the water purifier in which the subordinate filter medium is used together with the activated carbon and the hollow fiber, the load on the activated carbon in the water purifier can be reduced and the life of the cartridge can be extended. Further, in order to effectively use the subordinate filter medium, it is preferable to use them as fine particles, and when a large amount of these subordinate filter medium is used, pressure loss at the time of using the water purifier becomes high and a sufficient amount of water can be obtained. It is difficult to make a water purifier. Therefore, a subordinate filter medium is sandwiched between the hollow fiber membrane module and the activated carbon filling portion to form a relatively thin uniform layer, whereby a water purifier in which these difficulties are improved can be obtained.
