It should be noted that the position of the air outlet end of the air pump 90 is closely related to the shape of the algae filtering net 32, for example, when the algae filtering net 32 is in a bag shape, the bag opening of the algae filtering net 32 is communicated with the water outlet end of the algae removing box 31, and the air pump 90 is communicated with the water outlet end of the algae removing box 31, so that the air pump 90 can conveniently spray air into the algae removing box 31, and spray the algae filtering net 32 from the inside to the outside of the bag, so as to blow off impurities adhered to the outside of the algae filtering net 32.
For another example, when the algae filtering net 32 is in other shapes such as a sheet shape or a plate shape, the algae filtering net 32 separates the algae removing box 31 into a plurality of sub algae removing chambers, and when the air pump 90 is communicated with the algae removing box 31, the air pump is only required to ensure that the sprayed air flow acts on the opposite side of the algae filtering net 32 to the side attached with algae, so that a better cleaning effect can be achieved on the algae filtering net 32. Therefore, the air pump 90 may be communicated with other parts of the algae removal tank 31 except the water outlet end, and the specific implementation will not be described again.
The algae-removing aerator 100 further comprises a fourth control valve 91, and the fourth control valve 91 is installed at the air outlet end of the air pump 90.

In an embodiment of the present invention, referring to fig. 1, in order to enhance the sedimentation effect of impurities such as algae, the inner diameter of the algae removal tank 31 is tapered from top to bottom to form a funnel shape, the sewage draining end of the bath removal tank is disposed at the lower end of the algae removal tank 31, and the impurities such as algae finally slide into the sewage draining end of the algae removal tank 31 along the inclined wall of the funnel due to gravity.
In an embodiment of the present invention, referring to fig. 4, the algae removal mechanism 30 further includes an interception net 104, and the interception net 104 is disposed at the water inlet end of the algae removal tank 31. The mesh of the interception net 104 is larger than that of the algae filtering net 32, so that larger impurities can be prevented from entering the algae removal box 31, and each channel is prevented from being blocked.
When the water inlet end of the algae removal tank 31 is set as a pipeline, the interception net 104 can be sheet-shaped and cover the pipe orifice of the pipeline to intercept, or the interception net 104 can be a net frame which frames the port of the whole pipeline and can be fixed on the pipeline or the shell 11, so that larger impurities can be intercepted to enter the algae removal tank 31 or prevent the pipeline from being blocked by the larger impurities, and hard objects can be prevented from impacting the pipeline to damage the water inlet end of the algae removal tank 31.
