摘　　要：臭氧接触池的水力特性直接影响着微生物消毒效果。利用计算流体力学(CFD)技术,采用欧拉多相流模型和标准k-ε湍流模型对单管臭氧接触池内的流场进行数值模拟。结果表明:单管式臭氧接触池内臭氧分布比较均匀,基本上没有"死区"现象的产生,可以保证较高的消毒效率,但是气体气泡大量聚集在接触池出口槽下方。模拟结果对单管式臭氧接触池的优化有一定的借鉴作用。The hydraulic characteristic of ozone contactor has a great impact on the disinfection effect of microorganism.Computational fluid dynamics(CFD) technique was used to simulate the flow field of a single-column ozone contactor.The Eulerian multiphase model and the standard k-ε turbulent model were used in the simulation.The results show that ozone distribution is relatively uniform in the single-column contactor.In general,there does not exist the phenomenon of 'dead zone',which helps to guarantee high disinfection efficiency.However,gas bubble was found to accumulate underneath the outlet trough.The results offer a sample for optimizing the ozonation system.
