Electromagnetic field coupling electro-Fenton reaction device

Abstract

The invention belongs to the technical field of industrial wastewater treatment and particularly relates to an electromagnetic field coupling electro-Fenton reaction device which comprises a reactor,an electrode, a solenoid coil, a direct-current voltage regulator, an air blower, an air inlet pipe, an air distribution plate, an air exhaust, a water inlet and a water outlet. The device utilizes mutual cooperation of an electromagnetic field and electro-Fenton reaction, the electromagnetic field generates a magnetic field with an adjustable strength, so that charged ions such as iron ions generate movement, and aggregation reaction is avoided; in an electro-Fenton reaction system, an air hole for air or oxygen is formed in a cathode plate, the cathode plate is reacted with the introduced oxygen to produce hydrogen peroxide under the action of currents without adding extra hydrogen peroxide, and the production efficiency of the hydrogen peroxide is improved at the same time, so that popularization and application of equipment are improved.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to an electromagnetic field coupling electric Fenton reaction device. Background technique [0002] Refractory organic wastewater has always been a major problem in the treatment of industrial wastewater. In the process of treating refractory organic wastewater, the traditional methods show shortcomings such as weak degradation ability and insufficient degradation products, which make it difficult to meet the discharge requirements. [0003] Fenton's method is an inorganic chemical reaction, using hydrogen peroxide (H 2 o 2 ) and ferrous ions Fe oxidize many known organic compounds such as carboxylic acids, alcohols, and esters into inorganic states. The reaction has a high ability to remove refractory organic pollutants, and has a wide range of applications in the treatment of printing and dyeing wastewater, oily wastewater, phenolic wastewate...

AI Technical Summary

Problems solved by technology

The reaction has a high ability to remove refractory organic pollutants, and has a wide range of applications in the treatment of printing and dyeing wastewater, oily wastewater, phenolic wastewater, coking wastewater, nitrobenzene-containing wastewater, and diphenylamine wastewater, but there are also many shortcomings. : On the one hand, a large amount of hydrogen peroxide needs to be added to the wastewater, which is costly; on the other hand, iron filings in the reactor are easy to harden, and the effluent has a high content of iron ions and a darker color

The above-mentioned defects seriously limit the popularization of this technology
