| 摘 要： | 本文采用PLIF(PlanarLaserInducedFluorescence)技术对蛇形消毒池内部的浓度场进行了试验研究。获得了恒定流多种工况下溶质对流扩散初始阶段的非恒定浓度场变化过程 ,以及恒定情况下的场内浓度分布。测量结果表明消毒池在恒定来流和恒定投放消毒剂的情况下 ,出口处水体浓度分布均匀且随时间变化不大 ,这可以充分保证消毒池出来的水体中消毒剂的残留浓度符合要求 ,达到较好的消毒效果。

| Abstract: | In this paper,Planar Laser-induced Fluorescence(PLIF) is adopted to get the concentration fields in a serpentine disinfection tank.Time averaged and instantaneous concentration distributions at representative locations in the disinfection tank are observed.The fluctuation properties of concentration are analyzed.It is found that the intensity of concentration fluctuation is weak and the disinfectant concentration is nearly uniform at the outlet,which ensures the required residual disinfectant concentration and the satisfactory disinfection result. |
