A review on the water treatment reactor by electron beam
摘要
Abstract
A lot of research has been conducted to study the reaction kinetics of electron beam(EB) treatment of wastewater. However,relatively less attention has been paid to the hydrodynamic behavior and absorbed dose distribution of the EB reactor which is crucially important for the EB treatment efficiency. Existing EB reactors were classified,analyzed and compared in this paper. Advantages and disadvantages of different kinds of EB reactors were briefly discussed. The waterfall and nozzle jet reactors were widely used and their flow coincided well with the requirement of electron beam,but very few systematic studies were conducted on them. The treatment capacity of the spraying reactors was relatively small and there were very few studies on the aerosol flow formed by them. As for up-flow and plate reactors,their absorbed dose distribution was less uniform. All previous studies didn’t consider the detailed hydrodynamic of the EB reactor and its effect on the absorbed dose distribution which is also considered as the future research area for EB reactor study. Computational fluid dynamic(CFD) method should be used to study the detailed hydrodynamic of the EB reactor,including the velocity,depth and density distribution of the flow. The Monte Carlo method incorporating CFD simulation result should be used to study the absorbed dose distribution of the flow. The configuration of the EB reactor should be improved to make the absorbed dose distribution more uniform.关键词
