Abstract

PURPOSE: To form a stationary circulation flow speedily upon resuming the operation, in an apparatus for cycling carrier particles, to which aerobic bacteria are adhered, with air bubbles, by arranging an injection disturber for pulverizing mudd balls.
CONSTITUTION: Sewage supplied into a fluid vessel 1 rises with carrier particles 5 through an air lift pipe 8 by aerating from a sparger 6, and then falls down outside the pipe 8 for circulation. Aerobic bacteria breed on the carrier 5 to form a biomembrane adhered thereto, and are cycled to biologically decompose and separate organic substances in the sewage. The disposed sewage containing partially stripped biomembranes overflows into a sedimentation pool 2, and discharged through a disposed water vessel 10. In this case, when the operation is stopped by a service interruption or because of holiday, the carriers 5 are accumulated and formed as bulky mudd balls. Therefore, part of the disposed water from the vessel 10 is mixed with air from an air blower 30 by an ejector 40, and the mixture is injected through an injection disturber 20 at the bottom of the vessel 1. The mudd balls are easily pulverized by making the direction of injection horizontal.
