フィルタの表面に銀を蒸着している。(Means for Solving the Problems) In order to achieve the above object, the present invention uses diatomaceous earth made from algae remains deposited on the sea floor, coral fossils, maifan stone, activated carbon, etc., which have excellent adsorption ability. A granular material of porous material, a mixture thereof, a molded body of an appropriate shape, etc. are used as the filter. Silver is then vapor-deposited on the surface of the filter thus obtained.
尚、このような銀の蒸着は、高温高負圧（高温高真空）

脱臭すると共に、不純物を除去し、しかも、フィルタの
吸着能を高くすることを特徴としている。In addition, this type of silver vapor deposition is carried out at high temperature and high negative pressure (high temperature and high vacuum).
It is characterized by the fact that the heat and high vacuum used at this time deodorize the material, remove impurities, and increase the adsorption capacity of the filter.

の腐敗を防止することができるようにしている。(Function) By constructing the filter with a porous material with excellent adsorption ability, various heavy metals, organic substances, etc. contained in water are adsorbed and retained on the filter, and the surface of the filter is heated to high temperatures. Silver is deposited in a vacuum and the filter material is deodorized at this temperature.In addition, the sterilization effect of silver ions sterilizes bacteria contained in the water and prevents the water from spoiling. I'm trying to be able to do that.

に除去しておく必要がある。The manufacturing method of the filter is based on a conventionally known method, and when manufacturing a filter using a material containing salt such as diatomaceous earth or coral fossil, it is washed with running water as shown in each example. It is necessary to sufficiently remove salt, etc. contained in the material.

満足するものであることが確認された。Incidentally, a water purification filter (Example (1)) obtained by using granular particles of maifan stone as a filter and depositing silver on its surface, and a filter obtained by using granular coral fossil particles as a filter and depositing silver on its surface. Water purification filter (Example ■) (all I kg
) was used to purify tap water (raw water) that was considered non-compliant with the water quality standards of the Water Supply Act, and the following results were obtained, all of which satisfied the water quality standards set by the Water Supply Act. It was confirmed that this is the case.
尚、大腸菌液が０（検出限界２．０ｐｐｂ以下）であっ

菌に殺菌、挿画効果にも優れていることが確認された。The reason why the E. coli solution was 0 (detection limit 2.0 ppb or less) was due to the elution of silver, and it was confirmed that it was excellent in sterilizing and inserting effects on general bacteria in addition to E. coli.
尚、サンゴ化石あるいは珪藻土等のようにカルシウムに

。<Effects of the Invention> As explained above, according to the present invention, harmful substances such as heavy metals and organic substances contained in water can be accurately filtered using the characteristics of a filter manufactured using a porous material as a raw material. While adsorbing and retaining the filter, the sterilization effect of the silver deposited on the surface of the filter sterilizes general bacteria and reliably prevents their propagation. Contained harmful substances can be accurately removed. In addition, since the filter is deodorized by heating during the silver deposition process, for example, even if boiling water is filtered, no odor will be generated.For this reason, the use of water purification filters has been improved compared to conventional filters. It can also be expanded.
