Fenton reactor

Abstract

The invention provides a Fenton reactor, belonging to the technical field of multi-stage treatment of water, wastewater, sewage or sludge. The Fenton reactor comprises a reaction tube and an output tube, wherein one end of the reaction tube is provided with an inlet, and the other end of the reaction tube is communicated with the output tube; the side wall of the output tube is provided with an output pump; a to-be-treated medium flows anticlockwise from the inlet to the output pump; a first adding opening and a second adding opening are sequentially formed in the inlet end of the reaction tube in a water inflow direction, and are used for adding ferrous sulfate and hydrogen peroxide respectively; the reaction tube is of a well type structure formed by connecting multiple sections of tubepieces, and at least one mixer is arranged on the well type structure; a liquid caustic soda adding port is formed in the end, connected with the output tube, of the reaction tube; liquid caustic sodapasses through the liquid caustic soda adding port; and a treated medium is discharged into a next procedure through the output pump. The Fenton reactor is applied to sewage treatment and has the advantages of small occupied space, high reaction speed and the like.

Description

technical field [0001] The application relates to a Fenton reactor, which belongs to the technical field of multistage treatment of water, waste water, sewage or sludge. Background technique [0002] In the sewage treatment process, the application of biochemical treatment is more common. However, after the current biochemical treatment, the water body still contains a large amount of refractory substances. When the conventional Fenton reactor reacts the water body after the biochemical treatment, due to its own limitations, the mixing of the dosing is difficult and cannot meet the actual requirements. The Fenton reaction requires mixing and a long reaction cycle; and its mixing, Fenton agent addition, liquid alkali addition, and water body transportation all require corresponding independent devices, which occupy a large space and are not conducive to sewage treatment.

Problems solved by technology

However, after the current biochemical treatment, the water body still contains a large amount of refractory substances. When the conventional Fenton reactor reacts the water body after the biochemical treatment, due to its own limitations, the mixing of the dosing is difficult and cannot meet the actual requirements. The Fenton reaction needs to be mixed, and the reaction cycle is long; and its mixing, Fenton agent addition, liquid alkali addition, water body transportation, etc. all need to correspond to their own independent devices, which occupy a large space and are not conducive to sewage treatment

[0003] The existence of the above problems will eventually lead to the defects of unstable water treatment effect, substandard, and increased production costs of enterprises.
