Abstract

The invention provides a tubular porous titanium membrane-ozone contact reaction device and its water treatment method, a cavity, a tubular membrane electrode and a counter electrode; the tubular porous titanium membrane electrode is arranged in the center of the cavity, and the counter electrode is arranged in the tubular membrane Inside the electrode, a separation material is provided between the counter electrode and the tubular porous titanium membrane electrode to prevent short circuit; the bottom and top of the cavity are respectively provided with an air inlet and an air outlet, and the lower end and upper end of the tubular porous titanium membrane electrode are They are water inlet and water outlet respectively, which are used to make waste water flow into and out of the tubular porous titanium membrane electrode; when in use, when the tubular porous titanium membrane electrode is used as the cathode, the counter electrode is used as the anode, and when the tubular porous titanium membrane electrode is used as the anode, the opposite electrode is used as the anode. electrode as cathode. The device can realize bubble-free and high-efficiency mass transfer of ozone in the whole system, and at the same time, efficiently transform at the membrane-electrode interface to generate hydroxyl radicals, which are used for the rapid degradation of refractory organic matter.

Description

Technical field[0001]The present invention relates to the field of water treatment, and more particularly to a tubular porous titanium film-ozone contact reaction device and a water treatment method thereof.Background technique[0002]In recent years, ozone catalytic oxidation technology has been widely used in the field of water treatment. However, in order to improve the effect of ozone catalysis, enhanced ozone mass transfer has become the main direction of research. In recent years, membrane-ozone contact reactors based on membrane-free agents have become a hot spot study. Patent (Application Number 201710583322.7) by using an inorganic hydrophobic film material such as polytetrafluoroethylene (PTFE), a membrane material such as PTFE (PVDF) as a gas diffuser, using film material special porous characteristics, the ozone is realized in the film interface. Effective mass transfer. Due to the occurrence of air bubbles during the entire mass transfer, it causes high mass transfer effi...
