Micro-charge sewage treatment method

Abstract

The invention discloses a micro-charge sewage treatment method, which comprises the following steps of: feeding the sewage into a water distributor through a water inlet, and implementing aeration treatment; conveying the sewage to the bottom layer of a reaction tank through the bottom of the water distributor, and forming an aerobic layer, an anoxic layer, an anaerobic layer and a natural breath layer for a biochemical reaction in the reaction tank from bottom to up by the sewage; conveying the sewage of the natural breath layer on the upper layer of the reaction tank to a micro-charge water groove by a flow impeller, wherein the sewage forms pool flow and participates in a reaction in the micro-charge groove; placing a metal medium and a neutral conductive connecting terminal in the sewage, electrically connecting the metal medium to the positive electrode of a direct current power supply and connecting the neutral conductive connecting terminal to the negative electrode of the direct current power supply, in order to form an electric loop; after the pool flow reaction in the micro-charge water groove, refluxing the sewage into the water distributor of the step 1; and treating the sewage from the step 1 to the step 5 in a circular manner, and discharging the sewage until the quality of the treated sewage meets the demand. Therefor, the problem of generation of a great amount of organic sludge is solved, and the secondary pollution is relieved.

Description

technical field [0001] The invention relates to a method for treating active sewage, in particular to a method for treating micro-charged sewage. Background technique [0002] In the process of organic wastewater treatment, the biochemical reaction of microorganisms is used to hydrolyze the particulate organic matter, carbohydrates, suspended pollutants and soluble organic matter in the sewage; the macromolecular organic matter is decomposed into small molecular organic matter; the insoluble organic matter is converted into soluble Organic matter, after hydrolysis, is further decomposed by oxidation-reduction reaction in the reactor. In order to speed up the reaction speed, make the reaction complete, and improve the reaction efficiency, metals are often added to the reactor as reaction catalysts to participate in the reaction, such as iron, etc., and the anode iron atoms release electrons (Fe: Fe- 2e→ Fe 2+ ), the reaction produces a large amount of Fe 2+ Into the water b...

Problems solved by technology

[0003] The invention provides a micro-charge sewage treatment method, the main purpose of which is to solve the problem of passivation on the surface of the metal medium block. The charge makes the metal medium oxidize continuously and effectively to produce cations, so as to improve the reaction activity and catalyze the oxidation-reduction effect.
