PROBLEM TO BE SOLVED: To provide a composite germicide enabling simple and safe germicidal treatment, and to provide a germicidal treatment method. SOLUTION: This composite germicide is characterized by consisting of an inorganic/inorganic composite with extremely high germicidal capability obtained by bearing a silver phosphate compound shown by Ag3PO4 or Ag4P2O7 in the pores of a porous inorganic carrier. The 2nd objective method for producing such a composite germicide is characterized by comprising synthesizing the silver phosphate compound in the pores of the porous inorganic carrier by applying multistage-fashion an impregnating crystallization method and bearing the silver phosphate compound in the pores, and the 3rd objective a germicidal treatment method for to-be-treated water or moisture-containing gases using such a composite germicide. This composite germicide has such germicidal characteristics that on contact of the bacteria in water or a moisture- containing gas with the composite germicide, the bacteria are completely exterminated within a short time by the surface characteristics thereof, namely, by the germicidal effect of the silver phosphate compound dispersed and borne in the form of microparticles therein, therefore enables the germicidal treatment of (to-be-treated) water or moisture-containing gases easily and safely. |
