Problems solved by technology

[0011] At the same time, the soluble electrodes widely used at home and abroad are mostly iron plates and aluminum plates as flocculants for sewage treatment, but the material consumption of the electrode plates is too high, easy to accumulate fouling, easy to age, and the service life is short (about 30 days), which increases the Wastewater Treatment Costs

Abstract

The invention relates to an electrode plate of an inert composite electrode adopting environment friendly technology (EFT), in particular to a negative plate of the inert composite electrode, and a preparation method and application of the electrode plate. After using the electrode plate, 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 an electrode plate of an inert composite electrode of environment friendly technology (EFT, Environment Friendly Technology), especially a cathode plate of an inert composite electrode, a preparation method of the electrode plate and an application thereof. Background technique [0002] Electrochemical water treatment technology is called "environmentally friendly" technology (EFT, Environment Friendly Technology. The main points of EFT electrochemical technology are: electrocoagulation / electrical floatation / co-precipitation technology, which is the application of electrochemical redox reaction principle, control Electrochemical method of pollution. Direct current of a certain voltage is passed into the electrolytic cell, and the wastewater passes through the electrolytic cell, so that the anion of the electrolyte in the wastewater moves to the anode, loses electrons at the anode and is oxidized, and the cation moves to the cath...
