[0025] The lower end of the pebble layer 71 is fixedly connected to the upper end of the quartz sand layer 72, and the lower end of the quartz sand layer 72 is fixedly connected to the upper end of the activated carbon layer 73;

[0026] The pebble layer 71 , the quartz sand layer 72 and the activated carbon layer 73 are sequentially connected from top to bottom and are all wrapped and arranged.

[0027] As can be seen from the above, the pebble layer 71 and the quartz sand layer 72 can filter particulate impurities of different sizes, while the activated carbon layer 73 can remove the odor in the sewage.

[0028] like Figure 3 , Figure 4 As shown, the stirring mechanism 8 includes a driving box 81, the left side of the driving box 81 is fixedly connected to the right side of the purification box 1, a motor 82 is arranged at the bottom of the inner cavity of the driving box 81, and a main rotating wheel 83 is arranged at the output end of the motor 82. The main rotating wheel 83 is sleeved and rotated with the outer wall of the auxiliary rotating wheel 85 through a belt 84, and the inner key of the auxiliary rotating shaft is connected with a screw rod 811, and the outer wall of the screw rod 811 is sleeved with a protective sleeve 812, and the outer wall of the screw rod 811 is threadedly connected with a scraper plate 813, and a limit plate 86 is welded to the left part of the lower end of the protective sleeve 812, and the limit plate 86 is fixedly connected to one side of the scraper plate 813 through a telescopic rod 87, and the output end of the motor 82 is drivingly connected with a rotating rod 88, and the outer wall of the rotating rod 88 is symmetrically welded with a plurality of stirring rods 89;
