Fenton coagulation integration

The Fenton coagulation integrated equipment is a necessary device for advanced oxidation of wastewater through Fenton reaction. By using fluidized bed method, most of the Fe3+generated by Fenton method is crystallized or precipitated on the surface of the fluidized bed Fenton carrier, which can significantly reduce the amount of chemical sludge generated by the traditional Fenton method (H2O2 addition is reduced by 10% to 20%, Fe2+addition is reduced by 50% to 70%, and sludge amount is reduced by 40% to 50%). At the same time, the iron oxide formed on the carrier surface has heterogeneous catalytic effect, and fluidized bed technology also promotes the chemical oxidation reaction rate and mass transfer efficiency, effectively improving the COD removal rate by 10% to 20% and saving treatment operating costs by 30% to 50%.

The Fenton method, as an advanced wastewater treatment technology, utilizes the chain reaction between Fe2+and H2O2 to catalyze the generation of highly oxidizing hydroxyl radicals (· OH), which can oxidize various toxic and difficult to degrade organic compounds. For the treatment of high concentration difficult to biodegrade wastewater, it can be used as a biological pretreatment to improve water quality, enhance the biodegradability of wastewater, and create favorable conditions for subsequent deep treatment. Especially suitable for the deep treatment of organic wastewater such as leachate that is difficult to biodegrade or is difficult to effectively oxidize by general chemical methods.
