When treating industrial wastewater, the micro-electrolysis catalytic oxidation method mainly removes pollutants in the wastewater through the combined effects of electrochemistry, oxidation-reduction, physical adsorption and flocculation precipitation. This method mainly uses the weak current spontaneously generated by iron and carbon elements to decompose pollutants in the wastewater during the treatment process.
Specifically, when the closely contacted iron and carbon are immersed in the wastewater solution, a weak intramolecular current will automatically be generated between the iron atoms and the carbon atoms, and this microcurrent will decompose the pollutants in the wastewater. Among them, the anode (positive electrode) reaction will oxidize organic matter and redox metal ions in the wastewater, generate harmless substances such as CO2 and water, and effectively remove and decompose pollutants such as organic matter and heavy metals. The cathode (negative electrode) reaction will reduce the redox metal ions in the water to metals, and oxygen will be precipitated at the same time, further removing heavy metal ions in the wastewater.
In addition, the micro-electrolysis catalytic oxidation method can also improve the treatment effect by aeration and oxygenation and backwashing of iron-carbon micro-electrolysis fillers. Aeration and oxygenation can provide sufficient oxygen for the micro-electrolysis reaction, promote the galvanic cell effect reaction, and weaken the concentration polarization through stirring and shaking, accelerating the electrode reaction. The backwashing of the iron-carbon micro-electrolysis packing can regularly remove pollutants on the surface of the packing and maintain the treatment effect of the packing.
