バイオソイル脱臭装置の開発

抄録

Offensive odor as well as noise is now an important environment problem to take countermeasures for preservation of environment. In 1988 NICHIBOH Co., Ltd., developed "Biosoil Deodorizing equipment" which utilizes microorganism in deodorizing. This equipment has been effectively used in deodorizing at sewage disposal plants. This system is improved on the defects of traditional soil deodorizing equipment and is free from maintenance in many years. In the field of air pollution purifying, microbiological technology is used only for deodorizing. A benefit of microorganism deodorizing equipment is lower maintenance costs comparing to the other methods such as activated charcoal adsorption and chemical treatment which have the same level of deodorizing performance, and it has no secondary pollution. In order to realize the system, it is important to set conditions for microorganism and to decide which odor components (which type of industry) we apply. In this paper, the odor regulation standards and deodorizing technology, and characteristics of Biosoil Deodorizing equipment and examples of its actual operation are reported.
