Embodiment 1

[0030] Carbon nanotubes and Ti 3 C 2 MXene was dispersed in dimethyl sulfoxide solution at a mass ratio of 9:1, and the mixture was homogeneously dispersed by ultrasonic treatment for about 10 min. Then, the composite material was loaded on a polyvinylidene fluoride (PVDF) membrane with a pore size of 5 μm by suction filtration with a vacuum pump, washed with ethanol solution and ultrapure water in turn, and dried in vacuum to obtain a composite membrane electrode. See figure 1 , SEM image see figure 2 .

[0031] For the treatment of a pharmaceutical wastewater, the concentration of influent pollutants is about 20mg / L. See Table 1 for the treatment effect.

Abstract

The invention relates to a membrane electrode used for an ozone / electrical filtration coupled water treatment system as well as a preparation method and application of the membrane electrode. The membrane electrode includes a substrate filter membrane and an electro-conductive catalytic component, the substrate filter membrane is an electrode bottom layer, and the surface of the substrate filter membrane is loaded with the electro-conductive catalytic component; and the electro-conductive catalytic component is aimed at the ozone / electrical filtration coupled system, and can improve the filtering performance of the substrate filter membrane and realize a synergistic reaction between ozone and electrochemical oxidation. The invention also provides the preparation method of the electrode. Electrochemistry / ozone coupled advanced oxidation and a membrane filtration technology are combined through a certain process, so that complementation and mutual promotion of the processes in a same reaction device are realized, the treatment efficiency is significantly improved, membrane pollution is suppressed, and efficient water treatment is realized.

Description

technical field [0001] The invention belongs to the technical field of membrane electrodes for water treatment, and in particular relates to a membrane electrode used in an ozone / electric filtration coupled water treatment system and a preparation method and application thereof. Background technique [0002] The purification and treatment of water and wastewater is crucial to ensuring ecological security and human health. At present, people's requirements for water quality are getting higher and higher, and the removal effect of traditional water treatment technology on some refractory wastewater and emerging pollutants needs to be improved. Efficient and environmentally friendly water treatment technology has practical needs and a broad market. [0003] Traditional electrochemical water treatment technologies are often limited by the conductivity of the water body and the mass transfer of the system. Using new materials to prepare membrane electrodes and construct a flow-t...
