Electro-Fenton reaction waste water treatment equipment

Abstract

The invention relates to electro-Fenton reaction waste water treatment equipment comprising electro-Fenton main equipment and an advanced reactor, wherein the electro-Fenton main equipment is internally provided with a first anode plate, a cathode plate and a second anode plate which are horizontally opposite, wherein both sides of the cathode plate are provided with extending cathodes, and the upper part is provided with a water outlet pipe connected with the depth reactor; the advanced reactor is internally provided with packing, an overflow pipe and a reflux pipe; negative poles of two DC power supplies are connected, and positive poles are respectively connected with a first anode and a second anode; an ampere meter respectively monitors working currents of the two DC power supplies; a water inlet pump, a reflux pump and a draught fan supply water and aerate from the bottom of the electro-Fenton reaction waste water treatment equipment; the first anode is a dimensionally stable anode with a titanium based surface coated with a stannum-antimony-iridium-tantalum composite oxide catalyst, and the second anode is a steel plate. When the electro-Fenton reaction waste water treatment equipment works, aerated air generates H2O2 in a cathode region and Fe<2+> in a second anode region, the H2O2 and the Fe<2+> form electro-Fenton reaction with waste water, organic pollutants contained in the waste water are degraded through hydroxyl radicals generated from the electro-Fenton reaction, the electro-Fenton reaction is continued after the H2O2 and the Fe<2+> enters the advanced reactor, therefore reaction retention time is ensured, and large-flow reflux is realized.
