Problems solved by technology

Chemical wastewater has high content of organic matter, poor biodegradability, high chroma and a large amount of toxic substances
Traditional physical and chemical treatment has limited ability to remove chroma and organic matter, and cannot meet emission requirements
Biochemical treatment has a high removal rate of organic matter, but this type of wastewater has poor biodegradability and contains a large amount of toxic substances, which will destroy the activity of microorganisms and make it difficult to operate the biochemical treatment system, so it is difficult for this type of wastewater to meet the discharge standards

Abstract

The invention discloses a micro-electrolysis double-Fenton reaction tower which is characterized in that an aerator pipe, a water inlet pipe, a hydrogen peroxide feed pipe, a backwash water inlet pipe and a manhole are formed in the periphery of a base of a cylinder; a mounting and supporting layer is tiled between the base and the cylinder; iron-carbon packing is filled inside the cylinder through a filling hole formed in one side of the cylinder; an annular overflow weir is arranged on an inner edge on the top of the cylinder; and a water outlet pipe is arranged on a cylindrical wall of the cylinder which corresponds to the annular overflow weir. According to the arrangement, the micro-electrolysis double-Fenton reaction tower disclosed by the invention has the advantages that synchronous electrolysis and oxidation of sewage are realized, most of organic matters and chroma in wastewater can be removed, and the biodegradability of the sewage is improved.

Description

technical field [0001] The invention relates to a device for treating refractory organic matter and chromaticity in sewage, in particular to a micro-electrolysis Fenton double reaction tower combining micro-electrolysis technology and Fenton oxidation technology. Background technique [0002] With the continuous development of chemical technology, more and more chemical wastewater is discharged, especially printing and dyeing, pharmaceutical, plastic wastewater and food wastewater. Chemical wastewater has high organic matter content, poor biodegradability, high chroma and a large amount of toxic substances. Traditional physical and chemical treatment has limited ability to remove chroma and organic matter, and cannot meet emission requirements. Biochemical treatment has a high removal rate of organic matter, but this type of wastewater has poor biodegradability and contains a large amount of toxic substances, which will destroy the activity of microorganisms and make it dif...
