Fenton oxidation process wastewater treatment process mainly includes acid regulation, catalyst mixing, oxidation reaction, neutralization, solid-liquid separation, reagent dosing and sludge treatment system. The process design parameters of Fenton oxidation method shall be determined through tests according to the requirements of inlet water quality, quantity and outlet water. The Fenton oxidation process should be operated in a continuous manner. When the amount of wastewater is small, it can be intermittent.
