Abstract

PURPOSE: To reduce feed frequency of a stock solution of a microorganism to facility for carrying out treatment by utilization of the microorganism and enable long-term continuous operation. CONSTITUTION: The stock solution of EM bacterium from a stock solution chamber 4 of EM bacterium is mixed with a nutritive source-supplying solution and fed into a culturing tank 1 in which porous bodies 2 containing bacteria and EM stones 3 are put. The stock solution of EM bacterium is cultured at ordinary temperature so as to become nearly the same extent as stock solution concentration in the culturing tank 1 and fed through a chemical pouring pipe 11 to the desired treating facility 13 by a chemical pouring pump 12 and dropped. Part of the cultured solution is taken out by a circulating pump 10 in order to increase culturing efficiency and recycled through a EM stone packing cylinder 8 to the culturing tank 1. Feed amounts of the stock solution and a supply solution can also be controlled by water level-controlling floats 14 and 14a.
