To control the generation of “(*slime*)” which became a problem when the papermaking process drain was reused, we examined sterilization tests by using ultraviolet (UV) radiation and hydrogenperoxide (HP) together. It was confirmed general bacilli was able to be sterilized by changing the amount of the UV radiation and the amount of the addition HP at an arbitrary level and the proliferation control was effective.Next, we examined the number of general bacilli which existed together on the household papers, such as toiletpapers and tissues. Hundreds of general bacilli a piece in toiletpapers detected and tens of it a piece in tissues. When the UV radiation was irradiated to these papers, it was understood not to detect a general bacillus by one side 30 (mj/cm2) level if both sides were irradiated. When UV radiation was irradiated after HP do atomization, it was confirmed to be able to sterilize even with the HP a low density and the amount of the UV radiation of a low level. Sterilization and the water processing technology by UV radiation and HP using together are thought to be a technology which can be used by various scenes of the papermaking process.
