An operation method of the energy-saving and environment-friendly defoaming countercurrent type microorganism fermentation tank according to the claims 1-9 comprises the following steps: a power supply is connected, a motor (2) and an air pump (58) are started, the motor (2) drives a rotating shaft (3) to rotate, the rotating shaft (3) drives a rotary defoaming disc (41) to rotate, bubbles generated in a fermentation tank body (1) are gathered on the upper layer of liquid, the rotary defoaming disc (41) drives a defoaming trembler spring (44) to rotate in the bubbles, the defoaming trembler spring (44) trembles to enable a movable thorn (49) on the defoaming trembler spring (44) to puncture towards different irregular directions all the time, most of the bubbles penetrate through and puncture, for generated small bubbles, the bubbles can gradually enter the upper part of the rotary defoaming disc (41) through inclined defoaming through holes (43) under the action of suction and pushing force when contacting the rotary defoaming disc (41), the bubbles are rubbed in the inclined defoaming through holes (43) to retain a large amount of liquid, the surface tension of the bubbles is increased, and part of the bubbles flow down after being broken, part of the bubbles rise to the upper part of the rotary defoaming disc (41) along the inner part of the inclined defoaming through hole (43), then the air bubbles are broken after further friction of friction particles (48) above the rotary defoaming disc (41), part of fine air bubbles flow into the converging tank (45) along the overflow tank (42), then flows into the cooling ring (411) along the inner wall of the rotating shaft (3) through the converging port (413), is cooled, is contracted and liquefied, then overflows out of the cooling ring (411) and flows into the lower part, and finally returns to the inside of the fermentation tank body (1), the air pump (58) repeatedly pumps the curve twisting bag (51) through the air pumping pipe (59), the curve twisting bag (51) continuously contracts and extends, the bottom of the curve twisting bag (51) is matched with the rotary defoaming disc (41) to continuously rub and extrude bubbles to promote the bubbles to break, thereby completing the whole use process of the defoaming counter-current type microbial fermentation tank based on energy conservation and environmental protection.
