When the concentration of unsymmetrical dimethylhydrazine in the wastewater is large, the flow of the wastewater can be properly reduced and the sampling amount of the catalyst can be increased, and on the contrary, the flow of the wastewater can be properly increased and the sampling amount of the catalyst can be properly reduced. Therefore, the unsymmetrical dimethylhydrazine amount treated in unit time in the degradation reaction mechanism is relatively stable, so that the fluctuation of each discharge index of the treated wastewater is relatively small.
