Energy-saving double-circulation unpowered automatic mixing Fenton reactor

Abstract

The invention discloses an energy-saving double-circulation unpowered automatic mixing Fenton reactor comprising a reactor shell, a base for supporting the whole reactor shell and an water inlet pump, wherein the top of the reactor shell is provided with an effluent weir; a reactive precipitation chamber, a reaction chamber and a mixed reaction chamber are sequentially arranged from top to bottom in the reactor shell; the mixed reaction chamber is internally provided with a diffusion system; the bottom of the reactor shell is provided with a dosing tube extending into the diffusion system; two shell walls of the reaction chamber are provided with external return pipes connected with the water inlet pump; the upper end of the water inlet pump is provided with a water inlet pipe which is communicated with the external return pipes and is provided with an acid adding system; an injection system is arranged between the water inlet pump and the diffusion system, one end of the injection system extends into the diffusion system, and the other end of the injection system is connected with the water inlet pump through a pipeline. The energy-saving double-circulation unpowered automatic mixing Fenton reactor is compact in structure, small in floor area and capable of realizing sufficient mixed reaction and sediment separation through combining double circulations in the reactor and external circulation.

Description

[0001] technical field [0002] The invention relates to the field of sewage treatment devices, in particular to an energy-saving double-cycle unpowered automatic mixing Fenton reactor. Background technique [0003] At present, for the advanced treatment of industrial wastewater, the macromolecules that are not easy to degrade in the wastewater are oxidized and reduced into small molecules that are easily degraded by adding some reagents. We usually call this kind of reaction the Fenton reaction. At present, this kind of reaction is In the reaction tank, the reaction tank not only occupies a large area, the reaction speed is not easy to control, the drug reaction is not sufficient, the sewage treatment is uneven, and it cannot be moved, which brings great inconvenience to the sewage treatment. Contents of the invention [0004] The object of the present invention is: aiming at the deficiencies of the prior art, in order to overcome the deficiencies of the prior art, the pr...
