Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

As shown in fig. 1 and 2, the sewage treatment septic tank of the scheme comprises a tank body 1, wherein an upper cover 14 is arranged at the upper end of the tank body 1, three partition plates 2 are arranged between the upper cover 14 and the tank body 1, the tank body 1 is sequentially divided into a concentration tank, a first fermentation tank, a second fermentation tank and a purification tank by the three partition plates 2, a feed inlet 5 and a discharge outlet 15 are respectively arranged at two ends of the upper cover 14, the concentration tank is close to the feed inlet 5, and the purification tank is close to the discharge outlet 15; the three partition plates 2 are all provided with material passing holes 3, the height of the material passing holes 3 on the three partition plates 2 is reduced from one side of the feed port 5 to one side of the discharge port 15 in sequence, the feed port 5 is provided with a filter screen 4, and the filter screen 4 is fixed on the upper cover 14; be provided with cutting knife 9 in the filter screen 4, cutting knife 9 installs on rotation axis 8, and rotation axis 8 passes upper cover 14 and motor 7's pivot fixed connection, and rotation axis 8 passes through the bearing with upper cover 14 and is connected, and motor 7 passes through support 6 and installs on upper cover 14.
