The electron accelerator is one of the safest radiation sources for radiation degradation, and the degradation effect of electron irradiation mainly depends on the energy of an electron beam and the intensity of the electron beam. The higher the energy of the electrons, the larger the range of electrons in the material, and the electron range is also related to the stopping power of the irradiated material. When a charged ion with velocity v charge ze passes through a pure blocking medium composed of elements with atomic number Z, due to inelastic collision with extra-nuclear electrons of the medium, the energy loss after a unit distance is the blocking power, which is determined by the Bethe-Block formula, the larger the blocking power, the smaller the range of electrons in the blocking power. The larger the beam current intensity is, the more electrons participating in degradation are, and the degradation efficiency is also higher. In the application, organic matters in the refractory wastewater generate strong oxidizing groups such as hydrated electrons and hydroxyl radicals under the excitation action of a high-energy electron beam, and the chains of heterocycles, aromatic hydrocarbons and the like are broken and mineralized in a microchannel reactor to form easily degradable substances such as micromolecular decomposers and the like.

Furthermore, aiming at the ultrafiltration clear liquid with different concentrations, the treatment requirement of the waste water with corresponding concentration can be met by adjusting the power of the electron beam of the high-energy electron beam generator. Under an ideal operation state, after the treatment of the advanced oxidation unit, the final products are carbon dioxide and water, and no harmful gas is generated.
And finally, the secondary decomposition liquid generated by the advanced oxidation unit enters a fine treatment unit, and is sequentially treated by a nanofiltration reactor and a reverse osmosis reactor to finally obtain reverse osmosis clear water. Meanwhile, the generated filtered concentrated water and sludge are treated by a post-treatment unit.
