中文摘要:

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。

英文摘要:

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.
