DETAILED DESCRIPTION - Ozone catalytic oxidation wastewater treatment device comprises a pure oxygen source bin, an ozone generator and a membrane element reactor connected in sequence, and a rotameter arranged between pure oxygen source bin and ozone generator. There is an electronic flow meter and a pressure sensor between the ozone generator and membrane element reactor. There is also a first ball valve and a second ball valve between the electronic flowmeter and pressure sensor, and a membrane module is installed in the membrane element reactor. The lower portion of membrane element reactor is connected to the waste water tank through peristaltic pump, and the upper portion is provided with a sampling detection port and an ozone degradation outlet, and a third ball valve is provided on the ozone degradation outlet. The components of ozone catalyst contains two or more mixtures of transition metal corresponding oxides, oxyhydroxide powder, ferrocene and magnetic iron oxide. The components of promoter contain oxides corresponding to nickel, cobalt, and molybdenum, or molybdenum disulfide, or a co-precipitated double-layer hydroxide that is an effective component of catalyst and promoter. The catalyst is nano powder, and ratio of the catalyst and co-catalyst is 16:1-2:1 ratio. The composition of adsorbent is mixture of two of coconut shell or nutshell activated carbon powder of more than 400 mesh, hydroxyl or carboxyl carbon nanotubes, graphene oxide, acid-base diatomaceous earth and nitrogen carbide powder modified by acid and alkali. The binder is an aqueous emulsion or suspension of polytetrafluoroethylene or polyvinylidene fluoride, and has 40-80 wt.% solid content. The pipe joints used between equipment are all PTFE polytetrafluoroethylene wear-resistant portion. An INDEPENDENT CLAIM is included for a method for treating the wastewater, which involves modifying surface, preparing coating solution, coating, applying the membrane module to a membrane element reactor to form an ozone catalytic oxidation membrane element reactor with 15-45% packing density, treating wastewater, and performing exhaust gas collection and sampling detection.
