| 摘 要： | 采用潜水泵作为紊动诱发装置，利用PIV测量了流场，研究了不同流量下紊动对污染物降解的影响规律。结果表明，紊动对污染物的降解有明显的影响，流量越大，紊动强度越大，污染物的降解率越高。对紊动强度与有无紊动水箱COD、NH4^＋-N、TN和TP降解增加量的变化曲线进行指数函数拟合，拟合结果良好，可以认为紊动对污染物降解的影响可以描述为“一级反应”理论。 |
| 关 键 词： | 紊动 污染物降解 PIV |

| Abstract: | 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. |
| Keywords: | turbulence pollutant degradation PIV |
