<p>PROBLEM TO BE SOLVED: To provide a device for efficiently and easily adding and proliferating a group of multiple microbial germs at a low cost in a short time without giving a sudden shock to the group when it is thrown in an aeration tank to culture and proliferate them. SOLUTION: This device comprises a combined cylindrical body 3, longer than is wide, consisting of an inner tube 1 and an outer tube 2 which are set concentrically to be freely attached/detached. The peripheral side wall of the inner tube 1 is formed to have a meshed screen 4, plural circulation holes 5 are formed on the peripheral side wall of the outer tube 2 and a space 6 is provided between both of the peripheral side walls to flow liquid. Plural pieces of carriers 8 on which the group of multiple microbial germs is supported are filled in the inner tube 1. The body 3 thus prepared is immersed in the aeration tank to start activity of the group and proliferate them.</p> |
