1. Experimental purpose and principle of the electro-flocculation reaction experimental device:
This experiment is to insert multiple sets of electrodes with alternating positive and negative electrodes into the wastewater. When direct current is applied, electrolysis, polarization of particles, electrophoresis, oxidation-reduction, interaction between electrolysis products and wastewater, etc. are generated.
When a soluble electrode (usually st*nless steel) is used as the anode for electrolysis, the metal of the anode will dissolve aluminum or iron cations and combine with hydroxyl (OH-) in the water to form aluminum and iron hydroxides with strong adsorption properties, which adsorb and condense impurity particles in the water to form flocs. This floc adheres to the microbubbles (hydrogen) generated on the cathode and is separated by *r flotation.
