More Information
Summary:The invention relates to a metronidazole pharmaceutical wastewater treatment method. The treatment method comprises the following steps: S1, constructing a pulsed electro-Fenton reactor: taking an inert electrode and an iron electrode as anodes, taking an air diffusion electrode as a cathode, and taking metronidazole pharmaceutical wastewater as an electrolyte; s2, operation: alternately electrifying the inert electrode and the iron electrode, and continuously electrifying the cathode to form pulse current. According to the treatment method disclosed by the invention, the metronidazole pharmaceutical wastewater is treated by adopting a pulse electro-Fenton technology, and the metronidazole in the metronidazole pharmaceutical wastewater can be efficiently removed through cooperation of various conditions. In addition, the step S1 and the step S2 of the treatment method do not need to additionally add a ferrous catalyst, the problems that a traditional Fenton oxidation method needs to additionally add the ferro
