Study on effect of turbulence on pollutant degradation
紊动特性对污染物降解的影响研究

The effect of turbulence on pollutant degradation was studied.A submerged pump was designed to create different flux.The hydraulic parameters were measured with the PIV instrument.The experimental results indicated that the higher the flux,the larger turbulence intensity and the degradation rate of pollutant.Exponential function fitting on the turbulent intensity and degradation of COD,NH+4-N,TN and TP was made,the results were good,and the effect can be considered as thefirst order reaction.
