Waste water treatment
The wastewater electrolysis treatment method is a method that uses the mechanism of electrolysis to transform the harmful substances in the original wastewater into harmless substances through the oxidation and reduction reactions on the positive and negative poles respectively in the electrolysis process, so as to realize wastewater purification. The electrolyzer is equipped with plates, which are generally made of ordinary steel plates. The electrolyzer can be divided into single polarity and double polarity according to the way of connecting the plate with the power supply. After being electrified, under the action of external electric field, the anode loses electrons and oxidizes, while the cathode gains electrons and reduces. The waste water flows through the electrolytic cell as the electrolyte, and oxidation and reduction reactions take place at the anode and cathode respectively, and harmful substances are removed.
