[0021] Further need to be explained, the water pump 3 water inlet pipeline is connected with waste water pipeline, when water pump 3 starts, can through the connection of water inlet pipeline and waste water pipeline, waste water is pumped into and is exported to nanobubble generator 4.

[0022] Further worth mentioning, the ozone generated by the ozone generator 1 is input into the nanobubble generator 4 through the air inlet pipe 2, and is mixed with the waste water pumped by the water pump 3, and then the step of generating ozone nanobubbles in waste water is realized.

[0023] Further, the oil discharge pump 6 is communicated with the top end of the air floatation device 5, the sludge discharge pump 7 is communicated with the bottom of the air floatation device 5, and the water outlet 8 is communicated with the middle lower position of the side of the air floatation device 5.

[0027] Further worth mentioning, after the waste water is input into the air floatation device 5, in the process of gradually rising, the nanobubbles continuously adsorb and flocculate the oil droplets and suspended particles in the waste water, so that the oil droplets and light suspended particles float to the top of the tank body and are discharged, the heavy suspended particles are settled to the bottom of the tank body 10 and are discharged, and the clean water flows downward and is discharged into the conical barrel 11, at this time, a large amount of hydroxyl radicals (·OH) are generated by the collapse of the ozone nanobubbles, and COD, BOD, ammonia nitrogen and the like are oxidized and decomposed, and heavy metals are passivated.
