LCO ozone efficient catalytic oxidation technology


Ozone catalytic oxidation technology is an efficient advanced treatment technology for sewage and wastewater, and become a hot application point in the field of wastewater treatment in recent years. Compared with ozone as a separate oxidant, the [, O H ] formed by ozone catalyst has a higher reaction rate and stronger oxidation capacity for organic matters, and even can oxidize almost all organic matters. The catalyst can catalyze ozone to oxidize simple organic matters in water to CO2 and H2O directly., or oxidize and decompose macromolecular organic matters into small molecules., which can be biodegraded easily.


(1) The composite porous high-strength silicon-aluminum catalyst carrier is doped with catalytic components which are not easy to lapse, thus improving the stability of the catalyst.  The carrier is prepared by a special preparation process, thus making it  higher mechanical strength and longer service life.

(2) Carefully screen the carrier and active components of catalytic filler, and combined with transition metals, rare metals and rare earth metals as the effective catalytic components to ensure continuous and high ozone oxidation efficiency.

(3) Various catalytic components can enhance the adaptability of the catalyst to different wastewater and improve the catalytic activity simultaneously .

(4) The mechanical strength of the catalytic filler is more than or equal to 100N/particle, the specific surface area is more than or equal to 280 m2/g, the catalytic filler has no loss and does not need to be added regularly when use.

(5) The filler can catalyze self-decomposition of ozone in water and increase the concentration of OH generated in water, thus improving the ozone oxidation effects. The oxidation efficiency is 2 ~ 4 times higher than that of pure ozone oxidation.

(6) The activation energy of the reaction can be reduced, or the reaction routine can be changed to achieve the aim of deep oxidation and maximum removal of organic pollutants.
