S2: the ozone generator (19) is started through an external power supply, the ozone generated by the ozone generator (19) can oxidize organic matters in the oxidation pond (17), meanwhile, the catalytic action of the magnetic field catalyst (18) can promote hydrogen peroxide to be rapidly decomposed into hydroxyl radicals, the treatment effect on the organic matters which are high in salt content and difficult to be biochemically degraded in the wastewater is good, the decomposed molecules are promoted to be in full contact with the ozone, the oxidation effect of the organic matters is improved, and then the second electromagnetic valve (16) is opened through the external control panel, so that the water after being oxidized is led into the purification pond (21);
s3: then the ultrasonic generator (24) is started through an external power supply, the ultrasonic wave emitted by the ultrasonic generator (24) can improve the purification effect of residual organic matters in the wastewater, and simultaneously, the ultrasonic generator assists the action of ozone oxidation in water, so that the organic matters can be oxidized into carbon dioxide and water, partial matters can be directly mineralized into salt, secondary pollution can not be generated in the treatment process, the water purification quality is achieved, the treatment effect on the wastewater is improved, meanwhile, the photocatalytic plate (23) can improve the catalytic decomposition capacity of the organic matters in the wastewater, the energy consumption or the cost is greatly reduced, the catalytic oxidation treatment effect is better, and then, the third electromagnetic valve (22) is opened through the external control panel, so that the water after catalytic decomposition is led into the adsorber (25);
S4: carry out adsorption filtration to the particulate matter and the precipitate of aquatic through adsorber (25), improved waste water purification effect, discharge through drain pipe (26) at last, waste water purification efficiency is high, and can improve the purification quality of waste water.
