The working method of the embodiment is as follows: firstly, accumulating a certain amount of surface water by using a muddy water tank 1, and intercepting large suspended matters such as branches, rots and the like in the water through a coarse filter screen 10 in the accumulating process; then, the surface water accumulated in the muddy water tank 1 is led into the filter cartridge 41 through the water inlet assembly 42 and filtered through the sediment filter screen 414, at the moment, the driving assembly 601 drives the rotating wheel 423 and the belt water pump 602 to operate, and further the filter cartridge 41 is driven to rotate so as to realize the process of filtering while discharging sediment and flushing; when the flowmeter 202 detects that a certain amount of surface water has been filtered or when the hall sensor 201 detects that the rotation speed of the filter cartridge 41 is reduced to a certain degree, the lifting bracket 6 is used for lifting to enable one end of the filter cartridge 41 to be lifted to be inclined, meanwhile, the blowdown assembly 43 is opened to discharge sediment accumulated in the filter cartridge 41, and after sediment discharge is finished, the bracket 6 is automatically lowered and the blowdown assembly 43 is closed.
It should be noted that: 1. when the actually required irrigation area has the topography of the altitude difference, the placement altitude of the muddy water tank 1 is higher than the placement altitude of the filtering water tank 3, namely, the muddy water tank 1 and the filtering cylinder 41 form the altitude difference, so that the surface water accumulated in the muddy water tank 1 naturally flows into the filtering cylinder 41 through the water inlet assembly 42 to be filtered by the topography; when the irrigation area actually required does not have the topography of the altitude difference, the surface water accumulated in the muddy water tank 1 needs to be powered by the submersible sand suction pump so as to flow into the filter cartridge 41 for filtration through the water inlet assembly 42. 2. In the filtering process, because sediment is continuously accumulated in the filter cartridge 41, the weight is increased, the rotation speed of the filter cartridge 41 is reduced, and the sediment can be fed back to the controller through the Hall sensor 201; further, in actual use, a threshold value of the water amount or the rotation speed may be set in advance, and when any factor is reached, the filter cartridge 41 is lifted and lowered to perform sand removal treatment.
