<p>PURPOSE:To efficiently remove the colloidal material generated as a result of a treatment by installing a circulator to circulate waste water from a contact filter tank to a fluidized bed type reactor across the contact filter tank and the fluidized bed type reactor. CONSTITUTION:Many pulverized particles 5 to which microorganisms stick are packed into a tank 2 into which the waste water is admitted and the particles 5 are fluidized or suspended by a stirrer 16 to clean up the waste water in the fluidized bed type reactor 1. Contact filter media 12 are packed into a tank 11 into which the treated water from the reactor 1 is admitted and the above-mentioned waste water is passed in said filter media 12 to clean up the waste water in the contact filter tank 10. The stirrer 16 or other driving device is utilized as a driving source and the circulator 17 to circulate the waste water from the contact filter tank 10 to the reactor 1 is installed across the tank 10 and the reactor 1. As a result, the colloidal material generated as a result of the treatment is efficiently and economically removed and the high-degree waste water treatment is efficiently executed.</p> |
