Abstract

The invention relates to a microwave electro-Fenton method for processing organic wastewater and a device thereof. Under the action of microwave, a boron-doped diamond film electrode is used as an anode material for electrochemical degradation processing, and organic pollutant containing wastewater is processed efficiently by an electrochemical method. According to the invention, the boron-doped diamond film electrode is utilized to continuously generate hydroxyl radical with strong oxidation capacity in a wastewater system containing divalent iron ions, and in-situ activation of the boron-doped diamond film electrode is carried out by means of thermal effect and non-thermal effect of microwave so as to increase activity of the electrode and promote mass transfer process during the degradation process of organic pollutants. Therefore, the oxidation capacity of the electro-Fenton reaction is enhanced, and mineralization reaction rate is effectively accelerated. In comparison with traditional Fenton and electro-Fenton methods, the processing effect of the microwave electro-Fenton method provided by the invention is effectively enhanced. The method provided by the invention is simple to operate, has a good effect of processing organic wastewater, and has a wide application prospect as well as development potential.
