The air flotation machine for electroplating wastewater treatment according to claim 4, characterized in that: the lower sides of the first branch pipe (7) and the second branch pipe (10) are communicated with a first air pipe (15), and one end of the first air pipe (15) is communicated with a second air compressor (302).
9. The air flotation machine for electroplating wastewater treatment according to claim 2, characterized in that: the lower surface of the bottom wall of the first box body (201) is fixedly connected with a second air pipe (16), and the second air pipe (16) is communicated with the first air compressor (202) through a hose.
10. The use method of the air flotation machine for treating the electroplating wastewater is characterized by comprising the following steps: the method comprises the following steps:
s1, starting a first bubble generation mechanism: the second motor is started, the first stirring shaft drives the first fixing net to rotate, the first air compressor is started, air is filled into the first box body, the first water pump is started, water is filled into the first box body, air flow and water flow generate convection, and therefore bubbles are generated; fine bubbles enter the first branch pipe through the first main pipe;
s2, starting a second bubble generation mechanism: the third motor is started, the second stirring shaft drives the second fixing net to rotate, the second air compressor is started, air is filled into the second box body, the second water pump is started, water is filled into the second box body, air flow and water flow generate convection, and therefore bubbles are generated; fine bubbles enter the second branch pipe and the third branch pipe through the second main pipe; meanwhile, the second air compressor fills air into the first branch pipe and the second branch pipe through the air pipe;
s3, starting a stirring mechanism: the first motor is started, the first motor drives the stirring blades to rotate through the stirring shaft, and on one hand, the stirring blades can enable water flows in the first branch pipe and the second branch pipe to generate centrifugal force, so that the water flows and bubbles in the first branch pipe and the second branch pipe quickly flow out of the first branch pipe and the second branch pipe, and the bubbles are prevented from being fused; on the other hand, the stirring blade can break the air entering through the air pipe into tiny bubbles, so that the number of the bubbles is increased; the electric wastewater can be treated.
