s3, controlling a water pump (8) and a liquid suction pump to start, wherein the water pump (8) pumps out farmland sewage in a storage tank (1), the pumped farmland sewage sequentially passes through a water drain pipe (9) and a spray pipe (11), finally falls down onto a vibrating plate (10) from a spray hole (31) of the spray pipe (11), the liquid suction pump pumps out liquid medicine in the storage tank, the pumped liquid medicine sequentially passes through a rotary joint (16), a hollow pipe (15), a bottom port of the hollow pipe (15) and an inner cavity of a water outlet disc (17), is finally sprayed downwards from a liquid outlet hole (18) of the water outlet disc (17), the sprayed liquid medicine also falls onto the top surface of the vibrating plate (10) and is mixed with the farmland sewage falling onto the vibrating plate (10), the liquid medicine and organic pollutants in the farmland sewage are subjected to chemical reaction to produce floccules, the floccules move downwards along with the inclined plane of the vibrating plate (10), then the liquid and the floccules enter a surrounding frame (23) of the surrounding frame (22), the liquid filter membrane (23) and the floccules sequentially pass through the filtering membrane (24) and the bottom port (24) of the hollow pipe (15), and finally fall into the water outlet hole (19) to the top surface of the filtering membrane (23) and cannot remain on the top surface of the filtering membrane (23);
s4, along with continuous operation of the water pump (8) and the liquid pump, after all farmland sewage in the storage tank (1) is pumped and discharged, the first batch of farmland sewage can be purified; then the driving motor (20) is controlled to start, the driving motor (20) drives the rotating piece (21) to rotate clockwise, the rotating piece (21) drives the surrounding frame (22) to rotate clockwise, floccules remained on the filtering membrane (23) gradually incline out of the surrounding frame (22) in the rotating process of the surrounding frame (22), and after the surrounding frame (22) rotates 180 degrees, the floccules in the surrounding frame (22) can be completely inclined;
s5, repeating the operations of the steps S2-S4, so that farmland sewage pumped into the storage tank (1) can be purified in multiple batches.
