Referring to fig. 1 and 2, domestic sewage enters the filtering ponds 1 through the water inlet pipe 2, and since the volume of impurities in the sewage is smaller than the aperture of the first filtering holes 410, the impurities can pass through the first filtering holes 410.
In addition, since the volume of the foreign matter is larger than the aperture of the second filter hole 420, the foreign matter cannot pass through the second filter hole 420, and the foreign matter is accumulated on the bottom plate 43 by the cooperation of the first filter plate 41, the second filter plate 42, and the two end plates 44.
Referring to fig. 2 and 3, the top ends of opposite side walls of the two end plates 44 are fixedly connected with main plates 5 respectively, telescopic cavities 51 are respectively formed in the opposite side walls of the two main plates 5, auxiliary plates 6 are slidably matched in the telescopic cavities 51, and two compression springs 7 are respectively propped between opposite sides of the two auxiliary plates 6 and the side walls of the corresponding telescopic cavities 51. When the end plate 44 is located in the filter tank 1 and is kept upright, the two sub-plates 6 are butted against each other.

In the same manner as described above, the remaining impurities on the bottom plate 43 can be entirely scraped off by the other end plate 44, the other main plate 5 and the other sub-plate 6.
Referring to fig. 1 and 2, as a worker removes debris from the floor 43, a portion of the sewage may be carried out of the filter tank 1 with the debris. For this purpose, the outer side walls of the filter tank 1 opposite to the two end plates 44 are respectively integrally formed with a reflux tank 11 with an open top, and a plurality of reflux pipes are communicated between the bottom wall of the reflux tank 11 and the filter tank 1.
When sundries are cleaned from the bottom plate 43 into the reflux tank 11, sewage is brought into the reflux tank 11, the sewage flows back into the filter tank 1 through the reflux pipe, and after the sundries are sufficiently dried, the worker cleans the sundries in the reflux tank 11.
Referring to fig. 1, 5 and 6, in order to avoid that unfiltered sewage is discharged from the water outlet pipe in the process of cleaning impurities in the filter assembly by workers, a plugging slot 101 is vertically arranged at a position of the side wall of the filter tank 1, which is opposite to the position communicated with the water inlet pipe 2, and a plugging plugboard 16 is inserted into and matched with the plugging slot 101.
Referring to fig. 1, 5 and 6, a through hole 161 for communicating the water inlet pipe 2 with the filter tank 1 is formed in the plugging plugboard 16, an elastic pull rope 18 is connected to the top of the plugging plugboard 16, and the elastic pull rope 18 is wound on the rotating shaft 152.
When a worker lifts the filter assembly by the lifting assembly, the plug deck 16 can be driven to move upwardly by winding the elastic pull cord 18 through the shaft 152. The plugging deck 16 has completely plugged the inlet pipe 2 before the bottom plate 43 moves above the inlet pipe 2.

The implementation principle of the municipal domestic sewage environment-friendly treatment system provided by the embodiment of the application is as follows:
the sewage passes through the first filtering holes 410 through the water inlet pipe 2 into the filtering assembly, and the foreign matters can be accumulated only on the bottom plate 43 because the diameter of the foreign matters is larger than that of the second filtering holes 420.
The worker rotates the rotary table 153, and the rotary table 153 drives the two winding wheels 155 to rotate in the same direction through the rotary shaft 152, so that the two second pull ropes 156 are matched upwards to integrally lift the filter assembly out of the filter tank 1. The worker inserts the plug pins 154 into the corresponding plug holes, locks the turntable 153, and the filter assembly is suspended.
Meanwhile, the elastic pull rope 18 is wound by the rotating shaft 152, the plugging plugboard 16 is pulled to move upwards by the elastic pull rope 18, the through hole 161 is staggered with the water inlet pipe 2, and the plugging plugboard 16 is plugged with the water inlet pipe 2.
The worker removes the hanger 9 from the hanger 10, pulls the locking pin 14 out of the locking slot, then rotates one of the end plates 44, and the end plate 44 drives the main plate 5 and the auxiliary plate 6 to rotate. When the two auxiliary plates 6 are staggered, the auxiliary plates 6 extend out of the telescopic cavity 51 and abut against the bottom plate 43 under the action of the deformation force of the corresponding pressure springs 7, the worker continues to rotate the end plate 44, the auxiliary plates 6 gradually retract into the telescopic cavity 51, and meanwhile sundries are scraped from the bottom plate 43 to the reflux pool 11. Thereafter, the worker re-attaches the hanger 9 to the corresponding hanger ring 10, rotates the end plate 44, and inserts the locking pin 14 into the corresponding locking insertion hole. The above operation is repeated, and the impurities remaining on the bottom plate 43 are scraped off into the other reflow bath 11 through the other end plate 44.
Thereafter, the worker pulls out the peg 154, rotates the turntable 153 in the opposite direction, unwinds the second draw cord 156 from the reel 155, and lowers the filter assembly back into the filter tank 1. The shaft 152 also unwinds the elastic pull rope 18, the plugging plugboard 16 moves downwards, and the through hole 161 is communicated with the water inlet pipe 2 again.
