However, the coarse screens and fine screens have limited effect in filtering hair. Hair may be retained on the coarse screens and fine screens. Once the hair is retained and accumulated for a long time, it may easily cause pipe blockage once it falls off, or the hair may flow downward from the gap between the coarse screen and the fine screen, and the hair cannot be effectively filtered. The hair enters the next stage of wastewater recycling and treatment, interferes with the wastewater recycling and treatment, affects the effect and efficiency of the wastewater recycling and treatment, and also has the risk of clogging the pipe.

That is to say, the dehairing piece can be a whole spherical piece, a cylindrical piece, or a plurality of spherical pieces passing through a rotating shaft side by side. When a dehairing piece is used, a large spherical piece is generally used, and the large spherical piece occupies the gap between the water inlet and the water outlet. When there are two or more pieces, spherical pieces that rotate relative to each other can be used, or cylindrical pieces or a plurality of spherical pieces passing through a rotating shaft side by side can be used.

[0007] In the above scheme: the comb teeth are made of plastic.

[0008] In the above scheme: when there are two or more hair removal pieces, adjacent hair removal pieces are driven to rotate relative to each other by the motor gear structure.
