[0016] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0017] 1. Combining the structures such as the anaerobic tower, aerobic tower, guide seat, adsorption roller and filter frame, it is convenient to carry out effective filtration and purification treatment on the hydrazine hydrate-containing sewage to be treated in the future, remove the heavy metal impurities doped in the hydrazine hydrate-containing sewage in advance, and then use the adsorption roller and filter frame to filter and adsorb the impurities doped in the hydrazine hydrate-containing sewage. Finally, the hydrazine hydrate-containing sewage can be effectively treated by adding reagents and the anaerobic tower and aerobic tower. When the hydrazine hydrate-containing sewage is input into the inner side of the treatment box, the heavy metal waste scraps doped in the hydrazine hydrate-containing sewage can be effectively filtered and removed by using the guide seat and the guide groove, and then the two rotating adsorption rollers can be used to further realize the adsorption and filtration treatment of the hydrazine hydrate-containing sewage, and then the filter frame is used to further filter the sewage. The treated hydrazine hydrate-containing sewage can be finally treated by the anaerobic tower and the aerobic tower, which is convenient and fast, and has higher efficiency and better treatment effect.

[0018] 2. Combined with the first motor, eccentric wheel, guide block and reset spring and other structures, it is convenient to realize the longitudinal reciprocating motion of the filter frame when the filter frame is used to filter and adsorb sewage in the subsequent process, and then the filter frame with longitudinal reciprocating motion can be used to effectively filter and treat sewage, thereby improving the treatment efficiency and treatment effect of sewage, and the overall practicality is higher. The operation of the first motor will cause the driving wheel to drive the driven wheel to move through the internal toothed belt, and then the rotation of the driven wheel is used to realize the rotation of the eccentric wheel. When the eccentric wheel rotates, it will push the filter frame, so that it drives the guide block to pull the reset spring along the vertical rod. The reverse force generated by the rotation of the eccentric wheel and the deformation of the reset spring can realize the longitudinal reciprocating motion of the filter frame, which is convenient for the subsequent better filtering and treatment of sewage;

[0019] 3. By utilizing the second motor, rotating shaft, mixing rod, spiral blades, and chemical tube structures, the hydrazine hydrate-containing sewage after purification and filtration can be mixed and stirred. At the same time, chemicals can be added through the chemical tube during stirring, so that the hydrazine hydrate-containing sewage can be filtered and purified. Since the chemical tube runs through the side wall of the treatment box and extends to the inner side of the stirring chamber, the chemical can be input into the inner side of the stirring chamber by cooperating with the output port opened on the surface of one end of the chemical tube. Then, the second motor works to drive the rotating shaft to rotate the mixing rod, spiral blades, and other structures, so as to utilize the rotating spiral blades and mixing rods and other structures to achieve sufficient mixing and stirring of the chemical and the hydrazine hydrate-containing sewage, so as to facilitate better treatment of the hydrazine hydrate-containing sewage.
