Description
Technical field
The present invention relates to a kind of wastewater treatment equipment, it is adaptable to the process of high concentration hard-degraded organic waste water, belong to technical field of waste water processing.
Background technology
Fenton's reaction is named because French scientist Fenton finds, Fenton (Fenton) reagent method is to add Fenton reagent in an acidic solution: hydrogen peroxide (H2O2) and ferrous ion (Fe2+), there is Fenton reaction when both contact, generate hydroxyl radical free radical (OH), react as follows:
H2O2+Fe+2→2·OH+Fe+3 (1)
If the H in Fenton reagent2O2And Fe+2Produced by electrochemical method scene, the most referred to as electro-Fenton reaction.
Electrocatalytic oxidation waste water treatment process is mainly anodic oxidation reactions, organic pollution at anode by direct oxidation and indirect oxidation.Anode in electrolysis bath is the core of electrocatalytic oxidation method, and modal anode is with titanium as matrix, at its surface metallization oxide (MOx) anode of catalyst, cause changing size, referred to as dimensional stable anode, i.e. DSA (Dimensional Stable Anode) anode owing to it is difficult to be corroded.When applying certain potentials to anode, H2O or OH-First on anode, electric discharge produces the hydroxyl radical free radical (OH) of physical absorption state, reacts as follows:
