摘要：对模型氧化塘离散数d进行了相似分析,结果表明,模型塘的离散数d可以推广到原型中去.在试验资料基础上,提出了计算氧化塘离散数d值的经验公式,该公式反映了氧化塘内的极慢流动特征.应用该公式预测了有横向导流墙时氧化塘内的离散数,与试验结果符合较好.

Abstract：It has been shown in this paper that the dispersion numbers obtained in models may be applied to prototypes. Based on the results of several tracer studies, empirical equations were obtained to predict d values of the ponds, which are more reasonable than those proposed by Arceivala and Polprasert. The d values of ponds with lateral baffles were predicted, which are in good agreement with those from tracer studies by Kilani and Ogunrombi.
