The invention discloses a Fenton advanced oxidation tower wastewater treatment device which comprises a cylindrical tower-shaped tower body, a water inlet, a water inlet distribution tank and a water outlet weir are arranged at the top of the tower body, a gate valve is arranged on the water inlet distribution tank and used for adjusting the reflux quantity through the opening degree, a water outlet is formed in the side wall of one side of the water outlet weir, the water inlet distribution tank is connected with a reflux pipe, the reflux pipe is connected with a reflux liquid inlet pipe, a water distribution pipe is arranged on the bottom side in the tower body and connected with a water distributor, a bottom plate is arranged in the tower body and located on the upper side of the water distribution pipe, the bottom plate and part of the inner wall of the tower body form a packing area used for stacking a solid-phase catalyst, and the water distributor is used for spraying inlet water of the water distribution pipe into the packing area. A crystal discharging opening is formed in the side wall of the middle lower part of the tower body. The solid-phase supported iron oxide catalyst carrier and the liquid Fe2+ solvent catalyst are utilized to realize catalytic oxidation of wastewater in a liquid-solid multi-phase reaction system, and the method has the advantages of small dosage, small sludge amount, reduction of secondary pollution and easiness in operation and maintenance.
Description
technical field [0001] The application relates to an environmental protection equipment used in the field of advanced treatment of biodegradable organic wastewater, in particular to a Fenton Advanced Oxidation Tower wastewater treatment device developed for efficient sewage treatment using Fenton's reagent heterogeneous catalytic oxidation process. Background technique [0002] Due to the presence of substances that are difficult to biochemically treat in some wastewater, such as long-chain organic matter in wastewater from petroleum and coal chemical industries, or effluent from biologically treated sedimentation tanks, these wastewaters are characterized by low BOD / COD values. To further reduce COD value, advanced oxidation treatment must be used. Among all the advanced oxidation treatment methods, the Fenton reagent method is a wet catalytic oxidation method that is widely used at present. The principle is H 2 0 2 Under the catalysis of Fe2+ liquid phase solution or ir...
