A high-efficiency integrated Fenton oxidation reactor

Abstract

The invention discloses an efficient integrated Fenton oxidation reactor which comprises a mixer, a mixer bracket, a pH regulation deflection device, an effluent weir trough, a water outlet pipe, a deflection baffle, a reactor main barrel body, a partition overflow perforated plate, an overflow perforated plate bracket, a barrel body bottom reinforcing chamfer, a barrel body bottom plate, a mixerbase, a ferrous dosing port, a ferrous feeding pipeline blender, a drainage pipe, a blow-down pipe, a hydrogen peroxide dosing pipe orifice, a water inlet pipe orifice, an incoming water acid feedingpipeline blender, a reinforcing angle ring, a pH instrument monitoring point device and an ORP instrument monitoring point device. In the reactor, three reactions are integrated; through different combination forms of the reactions, the reaction rate is increased, the equipment volume and the floor area are reduced, and the equipment investment is lowered; through the combination mixing way, the agent utilization rate is increased, the dosage is reduced, and the operation cost is lowered; through the combination mixing way, the oxidation reaction effect is improved so as to increase the removal rate.

Description

technical field [0001] The invention relates to the field of sewage treatment and purification devices, in particular to an efficient integrated Fenton oxidation reactor. Background technique: [0002] The existing Fenton oxidation tank consists of a pH adjustment tank, a ferrous reactor, a hydrogen peroxide oxidation reactor, and each reactor needs to be equipped with a stirring system to form a wastewater purification system; it is widely used in the treatment of high-concentration organic wastewater; currently The Fenton oxidation pond used in the existing wastewater treatment project not only has a large area, high infrastructure investment, low reaction rate for a long time, large consumption of chemicals, high energy consumption and other problems; in view of the above shortcomings, in the traditional Fenton oxidation pond On the basis of the research and development of new high-efficiency Fenton oxidation facilities and equipment, the new high-efficiency integrated Fe...
