[0100] Step 4: When the sewage flows, the solid impurities at the bottom will flow into the collecting box 90 through the feed hole 91 and remain in the collecting box 90, so that the solid impurities in the sewage can be filtered.

[0101] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
