Abstract

<P>PROBLEM TO BE SOLVED: To provide a cultivation apparatus by thermophiles which can simply treat contaminants in situ by a compact apparatus. <P>SOLUTION: When a driving apparatus 5 is operated, a rotary container 3a is rotated in a closed container 4, and a processing material and the thermophiles are agitated in the rotary container 3a and moved vertically and repeatedly in the container 3a while being mixed. When the driving apparatus 5 is operated, a warm air producing apparatus 6 is operated approximately simultaneously. As a result, warm air passes through from piping 7a through channels 7b, 7d, and 7f in turn and is ejected form an ejection opening 3b into a mixer 3 to heat the processing material and the thermophiles. Since the warm air supplied into the mixer 3 is kept at a temperature suitable for the propagation of the thermophiles, the thermophiles propagate while eating the processing material in the mixer 3, so that the contaminants such as PCB and dioxin in the processing material are decomposed. <P>COPYRIGHT: (C)2004,JPO
