Since the peripheries of the multiple rotating rods four are respectively provided with breaking rods, and each two groups of the rotating rods four and the breaking rods will be located on both sides of the upper part of a filler rack, the filler can be broken up and loosened. At the same time, the other two bevel gears three on the periphery of the three rotating rods two also drive the bevel gear four and the central rotating rod three and the surrounding stirring rack to rotate. Therefore, when the filler is broken up, the stirring rack can fully and evenly stir the mixed area of ​​the filler and sewage, thereby creating opportunities for full contact between the filler and sewage, thereby improving the denitrification and denitrification effect.

At this time, two filter frames with different filter seams distributed in parallel up and down inside the pre-filter box will separate the impurities from the sewage again. Subsequent personnel can also use the cooperation of two sets of screw grooves, bolt rods and sliding guide frames to disassemble the two filter frames. BRIEF DESCRIPTION OF THE DRAWINGS

The sewage that has settled and removed particles in the sedimentation tank will enter the pre-filter box 2 along the connecting pipe 3.

[0027] Among them, the auxiliary denitrification mechanism 8 includes a mounting frame 81, and the mounting frame 81 is fixed to one side and the top of the denitrification box 1. The mounting frame 81 and the denitrification box 1 are jointly installed with a stirring assembly 82. The stirring assembly 82 includes a rotating rod 821, and the rotating rod 821 is installed at the internal top of the mounting frame 81. The output end of the rotating rod 821 is connected to the motor 822, and the periphery of the rotating rod 821 is divided into three bevel gears 823, and the same side of the three bevel gears 823 is engaged with a bevel gear 2 824, and the middle of the three bevel gears 2 824 is fixed with a rotating rod 2 825, and the middle of each of the three rotating rods 2 825 is fixed with a bevel gear 3 826 on both sides of the middle, and one side of the multiple bevel gears 3 826 is engaged with a bevel gear Four 827, a rotating rod three 828 is fixed in the middle of the plurality of bevel gear four 827, and a stirring frame 829 is distributed around the plurality of rotating rod three 828, and a linkage breaking up assembly 83 is installed on both sides of the middle of the three rotating rods two 825, and the linkage breaking up assembly 83 includes a bevel gear five 831, and the bevel gear five 831 is distributed on both sides of the middle of the three rotating rods two 825, and one side of the three pairs of bevel gear five 831 is meshed with a bevel gear six 832, and a rotating shaft 833 is fixed in the middle of the bevel gear six 832, and a synchronous wheel one 834 is fixed around the rotating shaft 833, and a synchronous belt 835 is sleeved around the synchronous wheel one 834, and a synchronous wheel two 836 is sleeved on the inner sides of the two sides of the synchronous belt 835, and the two synchronous wheels two 836 are sleeved on the inner sides of the A rotating rod 4 837 is fixed in the middle, and a breaking rod 838 is distributed around the two rotating rods 4 837.

After the sewage is filtered through the pre-filter box 2, it will enter the denitrification box 1. At this time, the two partition plates 5 divide the space in the denitrification box 1 into three parts, and the sewage will enter the middle area in advance and undergo initial mixing and denitrification with the filler on the filler rack 7 separated from the middle area. Then the initially denitrified sewage will be diverted to the two side areas along the water inlet 6 opened above the two partition plates 5. There are also two sets of filling racks 7 on each side. Since the types of fillers above the filling racks 7 in the middle area and the two side areas are different, the sewage diverted into the two side areas can be mixed with the multi-layer fillers to achieve the effect of secondary denitrification of sewage. During the mixing process, in order to prevent the fillers on the filling racks 7 from piling up into blocks, the personnel can start the motor 822 when the sewage is mixed with it to rotate the rotating rod 1 821 and the three bevel gears 1 823 around it. At this time, the three bevel gears 1 823 will drive the bevel gears 2 824 and the rotating rod 2 825 on one side of each other to rotate. In this state, the three rotating rods 2 825 will drive the bevel gears 5 831 on both sides of each other to rotate, and make them mesh with the bevel gear 6 832 and the middle rotating shaft 833 for transmission, wherein,The synchronous wheel 1 834 provided around the rotating shaft 833 rotates with the synchronous wheels 2 836 on both sides and the central rotating rod 4 837 via the synchronous belt 835. Since the multiple rotating rods 4 837 are surrounded by the scattered rods 838, and each pair of the rotating rods 4 837 and scattered rods 838 is located on both sides above a packing rack 7, the packing is scattered and loosened. At the same time, the other two bevel gears 3 826 located around the three rotating rods 2 825 also rotate with the bevel gears 4 827, the central rotating rod 3 828, and the surrounding stirring racks 829. Therefore, when the packing is scattered, the stirring rack 829 can fully and evenly stir the mixed area of ​​the packing and sewage, thereby creating opportunities for full contact between the packing and sewage, thereby improving the denitrification and denitrification effect.

[0028] Working principle: The sewage that has settled and removed particles in the sedimentation tank will enter the pre-filter box 2 along the connecting pipe 3. At this time, the two filter racks 42 with different filter seams distributed in parallel up and down inside the pre-filter box 2 will separate the impurities from the above sewage again. Subsequent personnel can also use the cooperation of two sets of screw grooves 44, bolt rods 45 and sliding guides 41 to disassemble the two filter racks 42. Secondly, after the sewage is filtered through the pre-filter box 2, it will enter the denitrification box 1. At this time, the two partition plates 5 divide the space inside the denitrification box 1 into three parts, and the sewage will enter the middle area in advance and The fillers on the filler rack 7 separated from the middle area are mixed and denitrified for the first time, and then the initially denitrified sewage will be diverted to the two side areas along the water outlet 6 opened above the two partition plates 5. Since two sets of filler racks 7 are also provided on the two sides, and since the types of fillers above the filler racks 7 in the middle area and the two side areas are different, the sewage diverted into the two side areas can be mixed with the multiple layers of fillers to achieve the effect of secondary denitrification of sewage. During the mixing process, in order to prevent the fillers on the filler rack 7 from accumulating into blocks, the personnel can start the motor 822 to rotate the rod 82 when the sewage is mixed with the filler rack 7. 1 and the three bevel gears 1 823 around it rotate. At this time, the three bevel gears 1 823 will drive the bevel gears 2 824 on each side and the rotating rod 2 825 to rotate. In this state, the three rotating rods 2 825 will drive the bevel gears 5 831 on both sides to rotate and mesh with the bevel gears 6 832 and the middle rotating shaft 833 to transmit the power. Among them, the synchronous wheel 1 834 set around the rotating shaft 833 will drive the synchronous wheels 2 836 on both sides and the middle rotating rod 4 837 to rotate through the synchronous belt 835. Since the peripheral parts of the multiple rotating rods 4 837 are respectively provided with The breaking rod 838, and the divided rotating rod four 837 and the breaking rod 838 are located on both sides of the upper part of a filler rack 7 in pairs, so as to break up and loosen the filler. At the same time, the other two bevel gears three 826 around the three rotating rods two 825 also rotate with the bevel gear four 827 and its middle rotating rod three 828 and the surrounding stirring rack 829. Therefore, when the filler is broken up, the stirring rack 829 can fully stir the mixed area of ​​the filler and sewage, thereby creating opportunities for full contact between the filler and sewage, thereby improving the denitrification and denitrification effect.
