Technological Advantage
(1)The alloy structure ensures that the "primary battery" continues to be highly efficient.
(2)Bigger specific surface area improves current density and better catalytic oxidation effect.
(3)High activity, low density, no passivation, no hardening, fast reaction rate, long-term stable and effective degradation resuits.
(4)Improved oxidation efficiency and expanded application range for wastewater treatment.
(5)Greatly reduces the operating intensity of workers.
(6)The treatment of wastewater by the filler integrates the oxidation, reduction, electro-deposition, flocculation, adsorption, bridging, sweeping and co-precipitation processes.
(7)The treatment cost is low and the wastewater biodegradability is greatly improved.
(8)The supporting facilities can be customized.
Application Field
1. Dye, chemical, pharmaceutical wastewater; Coking and petroleum wastewater;
-- COD value decreased significantly and BOD/COD value increased significantly after the wastewater treatment.
2. Printing and dyeing wastewater; Leather wastewater;
-- Good application for decolorization and obvious removal of COD.
3. Electroplating wastewater; Printing wastewater; Mining wastewater; Other wastewater containing heavy metals;
-- Heavy metals can be removed from the above-mentioned wastewater.
4. Organic phosphorus agricultural wastewater; Organochlorine agricultural wastewater;
-- Greatly improve the biodegradability of the above wastewater, and can remove phosphorus, sulfide.
MICRO ELECTROLYTIC FILLER / Iron carbon based catalyst


Catalyst Production
This series of catalysts is a kind of multi-component catalytic oxidation catalyst developed for the characteristics of organic wastewater which is difficult to degrade and biochemical. It has obtained a national invention patent and is the inventor of a new micro-electrolytic catalyst in China. It is a new type of unbonded micro-electrolytic catalyst, which is produced by multi-metal alloy fusion catalyst and high temperature microporous activation technology. When acting in wastewater, COD can be removed efficiently, chroma can be reduced, biodegradability can be improved, the treatment effect is stable and lasting, and the phenomenon of catalyst passivation and hardening can be avoided in the process of operation.
