[0075] In the present invention, when in use, sewage enters the filter box 1 through the water inlet pipe 8, and then the sewage passes through the high-speed pipe 11, which can leave substances inside the sewage in the high-speed pipe 11, and the sewage in the water inlet pipe 8 enters the multiple through holes 1 and the filter box 1, and the sewage passes through the filter screen 1 23 and the filter screen 25 and falls on the inner wall of the bottom side of the filter box 1. When the substances inside the spiral rod are transported to the large object box 9, by starting the drive motor 13, the output shaft of the drive motor 13 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the first sprocket 15 to rotate, and the second sprocket 17 is driven to rotate by the first chain 16, and the second sprocket 17 drives the spiral rod to rotate. In the process of filtering, the large substances inside the sewage can be transported to the large object box 9, and then the large object box 9 The internal sewage enters the filter box 1 through the drainage net 1, and the large substances (such as suspended matter, impurities, etc.) in the sewage are intercepted and transported to the large substance box 9 through filtering, which can significantly improve the water quality and avoid clogging or wear of subsequent treatment facilities. When the sewage is filtered, the first bevel gear 18 is driven to rotate by the rotating shaft 14, the first bevel gear 18 drives the second bevel gear 19 to rotate, and the second bevel gear 19 drives the rotating shaft 20 to rotate.

After the filtering is completed, by starting the first water pump 26, the sewage enters the mixing box 2 through the pipe 1. When the sewage is added, the oxidant is poured into the feeding box 27 through the feeding port 28 to convert the toxic substances in the sewage into non-toxic or low-toxic substances. By starting the drive motor 29, the output shaft of the drive motor 29 drives the stirring shaft 30 to rotate, the stirring shaft 30 drives the third bevel gear 32 to rotate, the third bevel gear 32 drives the two fourth bevel gears 33 and the fifth bevel gear 76 to rotate, the two fourth bevel gears 33 drive the two feeding rods 34 to rotate, and the two feeding rods 34 drive the feeding plate 3 5 is rotated to open the feeding plate 35, so that the oxidant can fall into the stirring box 2.
