The invention provides an electrochemical membrane filtration device based on a titanium fiber composite electrode and a water treatment method thereof, comprising: a cavity (1), a hollow fiber membrane (2), a titanium fiber composite anode (3) and a titanium fiber composite cathode (4); the hollow fiber membrane (2) is installed in the center of the cavity (1), the titanium fiber composite anode (3) is wound on the outer wall of the hollow fiber membrane (2) in a spiral shape, and the titanium fiber composite cathode (4) is Helically attached to the inner wall of the hollow fiber membrane (2); the membrane wall of the hollow fiber membrane (2) is used as an electrode separation material to avoid short circuit; the side walls of the cavity (1) are respectively provided with water inlets (5 ) and a water outlet (6), used to pass into and discharge the water to be filtered, the two ends of the hollow fiber membrane (2) pass through the top and bottom of the cavity (1) through the pipeline respectively, so that the hollow fiber membrane ( 2) The inside of the electrode is directly connected with the outside, and this device can significantly reduce the cost and improve the utilization rate of the electrode quality.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an electrochemical membrane filter device based on a titanium fiber composite electrode and a water treatment method thereof. Background technique [0002] In recent years, electric filtration technology has received extensive attention in the field of water treatment technology. Since this technology fully couples electrochemistry and filtration technology, especially making full use of the forced convection in the filtration process, the pollutants are continuously transported to the electrode surface, which significantly reduces the mass transfer limitation of the electrode, thus improving the electrochemical system. current efficiency and oxidation efficiency. Based on the above technologies, many new conductive membrane materials based on water treatment membrane substrates have been developed, mainly organic or inorganic membrane materials with carbon materials as ...
