Review on Hydrodynamic Behavior of Continuous Flow Reactors for Water Treatment by Electron Beam

Water pollution is one of the most significant environmental issues in China and the world. Electron beamElectron beam water treatment (EB) treatment of water, which is a new technology for water treatment, provides a new way to remove the pollutants that can’t be degraded by traditional water treatment technology. For the past few decades, the biological and chemical effect of electron beamElectron beam water treatment (EB) on wastewater has been studied a lot. Comparatively less attention has been paid on the hydrodynamic behavior of the flow reactors for water treatment by electron beamElectron beam water treatment (EB reactors). The hydrodynamic behavior of EB reactorHydrodynamics behavior of EB reactors is crucially important for EB treatment efficiency. In this paper, EB reactors were analyzed and compared, the advantages and disadvantages of different kinds of EB reactors were briefly reviewed. Previous studies on EB reactors mainly focus on the experimental study on velocity, depth and mean absorbed dose of the flow formed by EB reactors, ignoring the detailed hydrodynamics of the EB reactorHydrodynamics behavior of EB reactors and its effect on the absorbed dose distributionAbsorbed dose distribution . Further research area on EB reactors was proposed. Computational fluid dynamicComputational Fluid Dynamic (CFD) (CFD) method should be used to study the velocity, depth and density distribution of the flow formed by EB reactors. The Monte Carlo methodMonte Carlo method , integrated with the CFDComputational Fluid Dynamic (CFD) simulation result, should be used to study the absorbed dose distributionAbsorbed dose distribution of EB reactors and therefore optimize the EB reactors to make the absorbed dose evenly distributed.
