Abstract
A sewage treatment method coupled with an organic membrane and electro-Fenton catalytic technology belongs to the technical field of sewage treatment in environmental engineering. The sewage treatment method is characterized in that a conductive polymer modified organic fabric membrane is used as a cathode membrane, while a stainless steel mesh is used as an anode, a Fenton reagent is formed in the vicinity of the membrane under the conditions of appropriate electric field, dissolved oxygen, pH value and ferrous ion concentration, and the reaction liquid is circulated through membrane filtration so that the Fenton reagent is dispersed in the system. For the characteristics of sewage, the type and the size of the cathode membrane, the voltage and the like can be optimized. Power generation microorganisms in sewage-treatment microbial fuel cells generate electric power by utilizing sewage, oxygen is reduced by using electrons transmitted from the anode while the organical membrane serves as the cathode; and hydrogen peroxide is formed to arouse Fenton reaction so as to degrade pollutants. The sewage treatment method provided by the invention has the following advantages that organic membrane separation is combined with the electro-Fenton catalytic technology, the pollution and the load of the membrane assembly are reduced, effective contact and reaction of the pollutants and the membrane electrode are enhanced by membrane filtration; and furthermore, through membrane filtration, large-particle pollutants difficult to degrade can be removed.
