Domestic sewage treatment device

Abstract

The invention provides a domestic sewage treatment device. The domestic sewage treatment device comprises a column-shaped sewage treatment box, a water inlet pipe and a water outlet pipe, wherein an inverted conical filtering funnel is arranged in the sewage treatment box; a filtering paddle is arranged at the bottom of the inner side of the filtering funnel; the filtering paddle comprises at least two filtering blades which are symmetrically arranged; each filtering blade is arc-shaped; a scraping plate is arranged at the end part of each filtering blade; the bottom surface of each filtering blade is parallel with the conical surface of the filtering funnel; a hairbrush is arranged at the bottom of each filtering blade; a through hole is formed in the side wall, on which the filtering funnel is arranged, of the sewage treatment box; the bottom surface of the through hole is parallel with the upper plane of the filtering funnel; and a U-shaped stirring paddle is arranged at the center of the bottom in the sewage treatment box and is driven by a second motor arranged at the bottom of the sewage treatment box. The domestic sewage treatment device has the advantages that the filtering device and the stirring device are combined, so the structure is compact and reasonable; garbage sundries in the domestic sewage can be effectively filtered and the maintenance cost is reduced; and the garbage sundries on the filtering funnel can effectively rotate to be separated from the filtering funnel under the action of the filtering paddle, so the filtering efficiency of the funnel is guaranteed.
