Problems solved by technology

[0010] Moreover, the soluble electrodes widely used at home and abroad are mostly iron plates and aluminum plates as flocculants for sewage treatment, but the electrode plate material consumption is too high, it is easy to accumulate fouling, easy to age, and has a short service life (about 30 days), which increases the waste water. processing cost

Abstract

The invention relates to electrolytic equipment for sewage treatment by environment friendly technology (EFT). After using the electrolytic equipment, the treated sewage can be discharged up to the standard and the service life of the electrode plate is greatly prolonged.

Description

Technical field [0001] The invention relates to a sewage treatment electrolysis equipment of Environment Friendly Technology (EFT). Background technique [0002] The electrochemical water treatment technology is called "Environment Friendly Technology" (EFT, Environment Friendly Technology). The main points of EFT electrochemical technology are: electric flocculation / electric flotation / co-precipitation technology, which is an electrochemical method that applies electrochemical oxidation-reduction reaction principles and controls pollution. Pass a certain voltage direct current into the electrolytic cell, let the wastewater pass through the electrolytic cell, so that the anions of the electrolyte in the wastewater move to the anode, and lose electrons at the anode to be oxidized, and the cations move to the cathode, and get electrons at the cathode to be reduced. . The use of this reaction causes the pollutant components to form water-insoluble precipitates, and the generated ga...
