  • 摘要: 利用计算流体力学软件Fluent,结合标准κ-ε模型和组分输运模型,建立了臭氧接触池和清水池的三维紊流模型;通过计算流体的停留时间分布曲线(RTD),对臭氧接触池的水力效率进行了模拟研究。在此基础上,提出了在清水池前段第一廊道设置臭氧接触池的合建方案。结果表明:单一的臭氧接触池水力效率较低,T10/HRT值仅为0.42;而臭氧接触池与清水池经过合建后,T10/HRT值达到0.65,其臭氧消毒水力效率提高了55%。
    Abstract: The computational fluid dynamics software Fluent was adopted to build the three dimensional model of ozone contactor and clear water tank,and a standard κ-ε model and a species transport model were employed.An optimized simulation of the hydraulic efficiency for ozone contactor and clear water tank was conducted through simulating and calculating the retention time distribution (RTD) curve.And on the above basis,the modified design of setting an ozone contactor in the first corridor of clear water tank was proposed.The results of our experiments indicated that the single ozone contactor had a low hydraulic efficiency with the T10/HRT=0.42.However,after the optimization of design by combining the clear water tank and the ozone contactor,the hydraulic efficiency increased by 55%,and the value of T10/HRT reached up to 0.65.
