<p>To provide excreta deodorization method and apparatus which prevent malodor emission from the treatment tanks, do not generate slurry, can dispense with the dipping-up of excreta, and therefore can dispense with the discharge of the treated excreta as sewage. Excreta deodorization method and apparatus whereby excreta flowing from a toilet are completely decomposed by aerobic bacteria in a pretreatment tank and a main treatment tank and discharged in the form of carbon dioxide and water vapor. Excreta (3) flowing into a pretreatment tank (1) from a toilet (A) are preliminarily decomposed by aerobic bacteria by blowing air into the tank (1) and the decomposed excreta overflow into a main treatment tank (12), where the excreta (14) are completely decomposed into carbon dioxide while keeping the bacteria at the optimum working temperature by using a heater (22) and blowing air into the tank (12) from a blower (15) through a tubular foot (18). The generated carbon dioxide is thus deodorized and discharged through a ventilator (27). Also malodorous ammonia is deodorized, because it is decomposed into hydrogen and nitrogen gases by the action of the aerobic bacteria. <IMAGE></p> |
