The primary filter screen 13 and the secondary filter screen 14 are respectively arranged in an inclined structure. Since the primary filter screen 13 and the secondary filter screen 14 are respectively arranged in an inclined structure, after the device realizes multi-stage filtering operation of sewage through the two, the filtered impurities will roll and accumulate along the inclined surfaces of the primary filter screen 13 and the secondary filter screen 14; a sewage outlet 15 is opened at one side of the processing chamber 1, and a group of sewage outlets 15 are respectively arranged adjacent to the positions of the primary filter screen 13 and the secondary filter screen 14, and a valve cover 16 is clamped on the inner side of the sewage outlet 15, and a group of valve covers 16 are respectively clamped to the primary filter screen 13 and the secondary filter screen 14. The stage filter screen 14 is arranged in abutment with each other. After completing the regular cleaning operation, the upper and lower sets of valve covers 16 can be re-installed into the upper and lower sets of sewage outlets 15, so that the valve covers 16 can block the sewage outlets 15, and prevent the opening of the sewage outlets 15 from affecting the subsequent sewage treatment operations; a guide platform 20 is provided at the middle and lower position of the inner side of the processing bin 1, and an inclined platform 17 is provided at the lower position of the inner side of the processing bin 1. A drain outlet 18 and a sludge outlet 19 are provided on the other side of the processing bin 1 from top to bottom. The height difference between the drain outlet 18 and the sludge outlet 19 is 45 cm. Due to the height difference between the drain outlet 18 and the sludge outlet 19, this structural setting will facilitate the entire device to discharge the filtered sewage and sludge in a corresponding manner in an upper and lower graded manner.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the upper and lower groups of sealing card plates 12 are fixedly connected by bolts, and the upper diversion port 11, the diversion inner cavity 9 and the lower diversion port 7 are connected from top to bottom.

The middle position of the top end of the sealing top cover 2 is connected with the liquid inlet 3, and the liquid outlet end of the liquid inlet 3 extends to the interior of the processing bin 1 and is connected to the liquid inlet end of the diversion outer box 5. The liquid outlet end of the diversion outer box 5 is opposite to the interior of the diversion inner support plate 10. After the diversion base 6, the conduction card seat 8, and the diversion inner support plate 10 are respectively aligned and clamped into the interior of the diversion outer box 5, the upper and lower groups of sealing card plates 12 will achieve contact and abutment, so that the device can perform bolt-fixed assembly on the combined installation of the diversion structure.

[0023] Working process: Before the sewage treatment equipment in the utility model is used, it is necessary to connect the sewage discharge pipeline to the outside through the liquid inlet 3. When the multi-stage screening rural sewage treatment device is needed to treat rural sewage, as the rural sewage is first sent into the inside of the diversion outer box 5 through the liquid inlet 3, first, under the sealing connection limitation of the upper and lower sets of sealing card plates 12, the sewage treatment equipment will first use the multiple upper diversion ports 11 opened on the inner bottom end surface of the diversion inner support plate 10 to pre-divert the sewage, and then use the diversion inner cavity 9 provided in the conduction card seat 8 and the lower diversion port 7 provided on the surface of the diversion base 6 to perform multi-stage diversion treatment on the sewage, so that the sewage can be evenly sent into the inside of the treatment chamber 1 in a directional diversion manner, and then as the sewage is diverted and taken out, the sewage treatment equipment will First, the sewage is filtered once using the primary filter 13, and then the sewage is filtered twice using the secondary filter 14. Then, the sewage is guided by the diversion platform 20 so that the sludge can be naturally precipitated on the slope surface of the inclined platform 17. The treated sewage can be quickly discharged through the drain port 18, and the accumulated sediment can be quickly discharged through the sludge outlet 19. In addition, after the sewage is treated by multi-stage filtration, the filtered impurities will be concentrated at the lower right position of the primary filter 13 and the secondary filter 14. After opening the upper and lower valve covers 16 respectively, the impurities accumulated above the primary filter 13 and the secondary filter 14 will be discharged outward through the inside of the sewage outlet 15, cooperating with the entire sewage treatment equipment to complete the regular cleaning operation.
