Air treating method using photocatalyst under interior illumination

摘要: A method of treating with a photocatalyst the air in bacteria-contaminated patient's room and malodorous substance-floating room. film an optical catalyst consisting semiconductor, such as titanium dioxide is set on inner surface wall or dwelling The irradiated light from general illuminating source, fluorescent lamp, optically excited small quantity ultraviolet rays contained lamp. wattage lamp distance between are selectively determined so that intensity energy which not less than band gap becomes 0.001-1 mW/cm2, preferably 0.01-0.1 mW/cm2. bacteria chemical compounds deposited photodecomposed.
