The invention discloses a method and device for
processing algae in water by using an electro-
catalysis oxidation way. The method comprises the steps of: step 10, powering on an
anode and a
cathode arranged in water to facilitate occurrence of electro-
catalysis oxidation between the
anode and the
cathode, wherein micro-
electric shock between the
anode and the
cathode directly kills
algae spores in the water; generating hydroxyl radicals OH and O2 on the surface of the anode; and generating H2 and H2O2 on the surface of the cathode; step 20, adhering to the
algae in the water by H2 bubbles andenabling the algae to float out of the
water level to form bubble-shaped algae mud together with the bubbles; and step 30, cleaning the bubble-shaped algae mud. The method and device for
processing algae in water by using an electro-
catalysis oxidation way disclosed by the invention has the advantages that: as
hydrogen bubbles are extremely small and the amount of the
hydrogen bubbles is great, plenty of
hydrogen generated by the cathode plays an
extremely good gas drifting function; as the algae in the water can be adhered and floated out of the
water level to form the bubble-shaped algae mud together with the bubbles, fine algae becomes to be cleaned easily; as the micro-
electric shock between the anode and the cathode directly kills the algae spores in the water, the processed algae inthe water no longer breeds; and the method for
processing the algae is efficient, low in cost and environment-friendly.
