<p>PURPOSE:To provide a purification method and its device which do not require an equipment for activating an aerobic biological membrane. CONSTITUTION:This purification method is to suck air to activate a medium by utilizing the water energy of a circulation pump 5. In addition, the device to use this method consists of a filtration tank 1 which is installed in a pond water and stores a purification medium for biological treatment, a circulation pump with a suction port opened on the top of the filtration tank 1 and a discharge port opened in a pond, an air aspiration pipe 7 attached to the discharge pipe 6 of the circulation pump, and an air/liquid separation device arranged on an drain pipe located behind the air aspiration pipe 7. Further, an aeration pipe of separated air is installed in the filtration tank 1, and oxygen is supplied to a purification medium automatically by driving the circulation pump 5.</p> |
