Effluent Fenton Advanced Oxidation Technology
Overview of Fenton's Advanced Oxidation Technologies for Wastewater
The Fenton Fluidization Reactor is the fourth-generation Fenton series of advanced sewage oxidation equipment developed for the advanced sewage treatment section with poor biodegradability and need to be upgraded. Due to its high COD removal rate, adaptability, strong anti-interference ability, strong oxidation ability and fast degradation rate, Fenton advanced oxidation method has become the preferred technology for the advanced treatment and pretreatment of most high-concentration refractory wastewater.
The high-efficiency Fenton fluidization reactor independently developed by the company has achieved a breakthrough in the core technology of instantaneous generation of hydroxyl radicals, instantaneous full contact with COD, uniform fluidization state in the entire reactor, and high efficiency removal of COD while achieving low dosage. It has the characteristics of greatly reducing the amount of iron sludge, low investment and operation costs, high tolerance to water quality changes, easy operation and maintenance, and small footprint.
Scope of application: pretreatment of wastewater with poor biodegradability, advanced treatment of wastewater.
Core technology
The Fenton fluidized bed reactor uses a precise dosing system and multi-dimensional flow field control to realize efficient mass transfer catalysis in the fluidized bed, so that the hydroxyl radicals are fully produced in large quantities and are in effective contact with COD instantaneously, and the multi-dimensional flow field is conducive to the valence iron generated by the reaction to be attached to the surface of the monomer in a complexed state, which is an advanced technology that combines the functions of in-phase reaction, out-of-phase reaction, support crystallization and FeOOH reduction and dissolution.
