Abstract
PURPOSE: To carry out the titled treatment effectively by a method wherein, in a biological waste water treating method, electric voltage is applied against organisms obstructing said treatment and only obstructing organisms are effectively exterminated.
CONSTITUTION: In a biological waste water treating method utilizing microorganism, in order to exterminate obstructing organisms such as earthworm, alga or plankton spoiling useful microorganisms by eating and obstructing the treatment, electric voltage is applied to said organisms. For example, a pair of electrodes is provided in a treating tank in an upwardly and downwardly movable manner and these electrodes are moved upwardly and downwardly while electric voltage of about 50W100V is applied between said electrodes intermittently or continuously to exterminate obstructing organisms. Moreover, in this case, if an electrolyte is added into a waste water to enhance the electroconductivity thereof, said obstructing organisms can be annihilated by applying low electric voltage or of short applying time.
