Abstract

The invention relates to a method for deeply transforming water pollutant perchlorate and a reactor, and belongs to the field of application of a water treatment technology. According to a technical principle, electrochemical reaction and microbial hydrogen autotrophy are organically combined; the perchlorate is firstly reduced into a chloride ion under the action of a cathode producing hydrogen and hydrogen autotrophic bacteria through electrolysis, then the chloride ion is oxidized into active chlorine under the action of electrochemical anodic oxidation, so that the deep transformation from the perchlorate to the chloride ion to the active chlorine is realized. The method disclosed by the invention can be used for thoroughly transforming the perchlorate into the active chlorine by organically combining the process with microbial hydrogen autotrophy reduction by sufficiently utilizing two aspects of reaction, namely electrochemical cathodic reduction and anodic oxidation, and can be used for further enhancing the quality of effluent water because the active chlorine has bactericidal effect. The method disclosed by the invention can be used for sufficiently overcoming the defects of non-thorough perchlorate transformation of the tradition biological technology and the like and realizing the thorough transformation of the perchlorate. The reactor disclosed by the invention has the advantages of high time and space efficiency and easy management and maintenance.

Description

Technical field

[0001] The invention relates to a method for removing perchlorate in water and belongs to the application field of water treatment technology. The present invention proposes a method and reactor for the deep removal of perchlorate from water by the synergistic effect of electrochemistry and biohydrogen autotrophic action. Specifically, the electrochemical reaction is organically combined with microbial hydrogen autotrophic. Perchlorate is first electrolyzed at the cathode Hydrogen-producing and hydrogen-autotrophic bacteria are reduced to chloride ions, and then chloride ions are oxidized under the action of electrochemical anodization to generate active chlorine. Active chlorine has the function of sterilizing and improving water quality, thereby realizing perchlorate β†’ Chlorine ion β†’ deep conversion of active chlorine. technical background

[0002] At present, due to the development of modern industry, perchlorate-containing substances are widely used. They are...
