Abstract

The invention discloses an electro-catalytic oxidation device and method for sewage treatment. The device comprises a transparent tank body and a plurality of electrode groups arranged in the tank body in sequence in a criss-cross manner from bottom to top; each electrode group comprises a plurality of electrodes horizontally arranged in parallel; each electrode is fixed on the side wall of the tank body through an electrode support; the part between the tank body and the electrodes is filled with a filler which comprises activated carbon, lanthanum ferrite, silicon dioxide and titanium dioxide which are uniformly mixed. The method comprises the steps of pH regulation, electro-catalytic oxidation and activated carbon filtration which are carried out in sequence. According to the electro-catalytic oxidation device and method disclosed by the invention, as the mixed filler of the activated carbon, the lanthanum ferrite, the silicon dioxide and the titanium dioxide is arranged in the tank body, on one hand, the current efficiency of electro-catalytic oxidation is improved, and the electricity consumption is reduced; on the other hand, by utilizing the light sensitivity of the lanthanum ferrite, visible light transmits through the tank body to irradiate to absorb and decompose macromolecular organic matters; moreover, the waste heat effect of silicon dioxide, titanium dioxide and electro catalytic oxidation reaction is realized, and the mineralization of the organic matters in sewage is accelerated.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to an electrocatalytic oxidation device and method for sewage treatment. Background technique [0002] Electrocatalytic oxidation technology is a recently developed "green technology" with great application prospects for the treatment of toxic and refractory pollutants. base, so that the refractory organic matter is converted into biodegradable organic matter, or the refractory organic matter is converted into carbon dioxide and water. [0003] At present, the electrocatalytic oxidation technology used for sewage treatment has multiple functions such as oxidation, reduction, neutralization, coagulation, and air flotation. In the process of treatment, no drugs are added, no new pollutants are produced, the amount of sludge is greatly reduced, and it can be combined with other technologies to achieve the purpose of comprehensive treatment. It is called an environmentally friendly new te...
