What is the principle of catalytic electrolysis?

Jun 03, 2018

The technology is to use microelectrolytic fillers to generate "galvanic cell" effect to treat wastewater without power.

When the water is flowing, there will be an infinite number of "original batteries" of 1.2V in the device.

The "original battery" USES wastewater as an electrolyte, and electrolysis and reduction treatment of wastewater by discharging the current to achieve the purpose of degrading organic pollutants.

In the process of the new ecological [. O H], [H], [O], Fe2 + and Fe3 + to many components of REDOX reaction and waste water, such as can break the hair colored wastewater of non-ferrous material base or base aid groups, chain scission, even achieve degradation decoloring effect;

Generated further oxidized to Fe3 +, Fe2 + them has strong adsorption of hydrate - flocculating activity, especially after alkaline adjust pH value to generate hydrogen ferrous oxide and iron hydroxide colloid flocculant, their flocculating ability is much higher than general agent hydrolysis of iron hydroxide colloid, to a large number of small particles dispersed in water flocculation, metal particles and organic macromolecules.

This technology has a wide range of application, good treatment effect, low cost, short processing time, convenient operation and maintenance, and low power consumption, can be widely used in industrial wastewater pretreatment and depth processing.

Application of wastewater types: dye wastewater, coking wastewater, pharmaceutical wastewater, pesticide wastewater, resin wastewater, fertilizer wastewater, leather wastewater, electroplating wastewater, papermaking wastewater, starch wastewater, garlic wastewater, waste leachate and other industrial waste water.

Anode: fe-2e to Fe2+ E (Fe/Fe2+) = 0.44v.

Cathode: 2H + 2e - H2 E(H + H2)=0.00V.

When aerobic presence occurs, the cathode reaction is as follows:

2H2O E (O2)= 1.23v.

O2 + 2H2O + 4e to 4OH, E (O2/OH) =0.41V.

It is composed of multi-metal alloy fused catalyst with high temperature micropore activation technology.

It can effectively remove COD, reduce chromaticity, improve biodegradability, and maintain stable and durable effects. Meanwhile, it can avoid the passivation and slacking of the packing in the running process.

This packing is an important guarantee for the continuous action of micro-electrolytic reaction, which brings new life to the treatment of electroplating wastewater.
