7. A method for treating land-based industrial mariculture tail water, which is characterized in that the land-based industrial mariculture tail water treatment device according to any one of claims 1-6 comprises the following steps:
s1: the method comprises the steps of (1) primarily filtering, enabling culture tail water in a culture pond to flow to the bottom end of a drainage channel (2) through a drain pipe (12), enabling waste water to flow rightward in the drainage channel (2), enabling a biological filter membrane (21) to primarily filter the waste water, and enabling the waste water to slowly flow along a W shape through a baffle plate (22);
s2: the vertical sedimentation is carried out, the wastewater is shunted through a shunt tube (23), then, the wastewater flows to the inner side of the vertical sedimentation tank (3) through a diffusion tube (4), the diffusion cover (41) and the conical body (5) are mutually matched, the wastewater is diffused in the vertical sedimentation tank (3), then, the wastewater slowly flows upwards, the sand filter bed (43) is used for blocking and filtering the wastewater, and the particle impurities are precipitated at the bottom end of the vertical sedimentation tank (3) and are discharged through a sludge tube (31);
s3: the motor (53) is enabled to operate to drive the conical body (5) to slowly rotate through the transmission rod (52), the conical body (5) improves the diffusion effect of wastewater through the guide vane (51), meanwhile, the transmission rod (52) drives the hairbrush (54) to rotate, the hairbrush (54) is enabled to adsorb suspended matters at the top end of the vertical sedimentation tank (3), and then water at the top end of the vertical sedimentation tank (3) flows into the overflow pipe (34) through the overflow weir (32) and the water collecting cover (33) in sequence;
s4: the water flowing out of the overflow pipe (34) flows into the aeration tank (6) through the collecting pipe (61), so that the wastewater flows mutually in the aeration tank (6), the filtering dam (62) further filters the wastewater, and meanwhile, the centrifugal fan (71) operates to aerate and aerate the wastewater in the aeration tank (6) through the aeration pipe (7) and the aeration head (72);
s5: biological purification, wastewater flows into the biological treatment tank (8) through the connecting pipe (81), the wastewater flows forward in the biological treatment tank (8), aquatic plants on the ecological floating bed (83) purify the water body, and then the purified water body is discharged outwards through the water outlet pipe (82).
