として家庭用浄水器が普及してきている。[Background Art] In recent years, interest in water has increased, and mineral water has become a big boom. Some of the reasons for this are the decline in the quality of tap water due to a decline in the quality of water in water source ponds, and the increase in population in cities. , there is a risk of foreign substances entering water tanks in condominiums, etc., and household water purifiers are becoming popular as a countermeasure.

いため多孔質中空糸膜が利用されている。[0003] Household water purifiers generally contain activated carbon, which absorbs calcium and certain organic substances contained in tap water, thereby improving the taste of the water. However, in such water purifiers, if the water flow is stopped and the water is left for a long time, the activated carbon will adsorb chlorine, reducing the sterilizing power of the chlorine, and furthermore, the organic substances adsorbed on the activated carbon will form a eutrophic state, which will inhibit general bacteria. breeds. When water flow is resumed in this condition, a large amount of common bacteria is found at the purified water outlet. Therefore, porous hollow fiber membranes are used to prevent the general bacteria that have grown in the activated carbon layer from flowing out from the purified water outlet.

されている。[0004] However, the general bacteria generated in large quantities due to reproduction are blocked by the porous hollow fiber membrane, and on the porous hollow fiber membrane,
As it continues to multiply, it becomes denutrientd and eventually the general bacteria die, producing a hydrogen sulfide odor. Therefore, porous hollow fiber membrane type water purifiers have been developed that add powdered activated carbon to the system to deodorize hydrogen sulfide generated by killing common bacteria.

少し、使用者に不快感を与えるという問題点があった。However, in the above conventional configuration, the porous hollow fiber membrane is covered with powdered activated carbon charged in powder form during transportation or installation of the porous hollow fiber membrane type water purifier. There was a problem in that the hydrophilic agent used in the porous hollow fiber membrane was adsorbed by the powdered activated carbon, causing the porous hollow fiber membrane to become hydrophobic. Furthermore, as a result, the amount of water flowing out during water flow is reduced, causing discomfort to the user.

ーティングされ脱臭作用をする。Powdered activated carbon is shaped into a tablet and fixed with water-soluble paper, so even when the water purifier is being transported from a factory or installed, shocks and vibrations can cause it to shatter, causing the powdered activated carbon to scatter and become porous. There is no contact with the hollow fiber membrane. During use, raw water enters the water purifier cartridge through the raw water inlet 3, passes through the granular activated carbon 5, and adsorbs calcium and organic matter. Furthermore, water flows upward and tablet-shaped powdered activated carbon 9
At this time, the water-soluble paper 10 that fixed the tablet-shaped powdered activated carbon 9 is dissolved, and the tablet-shaped powdered activated carbon 9 is disintegrated by the water flow and becomes powder, and is coated on the porous hollow fiber membrane 8. It has a deodorizing effect.

できるものである。[Effects of the Invention] As described above, the present invention provides a cartridge in which powdered activated carbon is packaged with water-soluble paper, etc., or is made into tablets, etc., fixed to the vessel wall with water-soluble paper, etc., and separated from a porous hollow fiber membrane. By placing the activated carbon inside the membrane, the powdered activated carbon will not scatter due to shock or vibration during transportation or installation and will not adhere to the porous hollow fiber membrane, thereby maximizing the deodorizing ability of the powdered activated carbon and significantly increasing its durability. In addition, it is possible to realize an excellent porous hollow fiber membrane type water purifier that does not reduce the amount of water flowing during water purification and also improves workability such as transportation and installation work. Furthermore, it is possible to realize a powder activated carbon composition that is convenient to handle, has improved workability, and has significantly improved durability of the deodorizing ability of activated carbon.
