Method and device for processing algae in water by using electro-catalysis oxidation way

Abstract

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.

Description

technical field [0001] The invention relates to a method and a device for treating algae in water by electrocatalytic oxidation. Background technique [0002] The treatment of algae in water is a difficult problem in water treatment technology. Algae in water can cause the following problems: 1. The water body is in anoxic state due to the growth of algae in the water, and aquatic animals die due to lack of oxygen; As a result, the content of organic matter in the water increases, and the bottom of the water body is caused by hypoxia and anaerobic bacteria proliferate and decomposes organic matter in the water, which causes the water body to stink and seriously affects the water quality; 3. Algae (mainly blue-green algae) that grow due to eutrophication of the water body , the toxins produced by the death of cyanobacteria will remain in the water body, which is difficult to deal with, which will lead to a bad impact on the water quality of the river basin and threaten the sa...

[0002] The treatment of algae in water is a difficult problem in water treatment technology. Algae in water can cause the following problems: 1. The water body is in anoxic state due to the growth of algae in the water, and aquatic animals die due to lack of oxygen; As a result, the content of organic matter in the water increases, and the bottom of the water body is caused by hypoxia and anaerobic bacteria proliferate and decomposes organic matter in the water, which causes the water body to stink and seriously affects the water quality; 3. Algae (mainly blue-green algae) that grow due to eutrophication of the water body , the toxins produced by the death of cyanobacteria will remain in the water body, which is difficult to deal with, which will lead to a bad impact on the water quality of the basin and threaten the safety of drinking water downstream. Therefore, the treatment of algae in the water body is an important part of water treatment

There are three major disadvantages in this method: first, it is difficult to filter fine algae; second, the efficiency is low no matter whether it is manual or mechanical; third, it treats the symptoms but not the root cause. , can only remove algae in a very short period of time, but failed to fundamentally solve the blue-green algae problem
