In this embodiment, the specific usage flow is as follows: referring to fig. 4, the wastewater in the feeding pond is pumped into the treatment tank 110 through the water inlet mechanism 200, at this time, the wastewater is filtered by the filter plate 120 and then is discharged from the water outlet tank 110a and the water discharge tank 410, when the filter plate 120 is blocked, referring to fig. 5, the driving mechanism 400 drives the back flushing mechanism 300 to work, the back flushing mechanism 300 washes the bottom of the filter plate 120, and further keeps the filter plate 120 to continuously filter until the residue at the top of the filter plate 120 is more, when the driving mechanism 400 drives the back flushing mechanism 300 to work, referring to fig. 5, the filter plate 120 simultaneously moves upwards, the doping on the surface of the filter plate is extruded until the blocking block 110c-2 blocks the through tank 110c, and referring to fig. 6, the slag discharging mechanism 500 works, the compacted residue at the top of the filter plate 120 is pushed out through the slag discharge port, then the blocking 110c-2 is reversely ejected into the through tank 110c-1, and then the wastewater in the water inlet pipe 220 continues to enter the treatment tank 110, the surface of the filter plate 120 is continuously filtered, the back flushing is performed until the bottom of the filter plate 120 is washed by the back flushing mechanism 300, and the slag discharging structure in the water inlet pipe 220 is automatically replaced, and the frequency of the filter plate 120 is automatically cleaned, and the frequency of the filter plate 120 is reduced.
Although the invention has been described hereinabove with reference to embodiments, various modifications thereof may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the features of the disclosed embodiments may be combined with each other in any manner as long as there is no structural conflict, and the exhaustive description of these combinations is not given in this specification merely for the sake of omitting the descriptions and saving resources. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
