摘要
文章对高氨氮溶液曝气吹脱系统运行情况进行了研究,对小气泡曝气条件下氨的传质情况作了一系列的假定和简化,推导出了曝气吹脱氨氮的理论模型,并对该模型进行了分析。通过进一步的实验,分析了不同曝气条件及溶液高度对总传质系数KL的影响。
Through the study of operation conditions of air stripping system,a chain of simplifications and assumptions concerning ammonia mass-transfer rate in the fine bubble aeration were made,on the basis of which the theoretical model concerning ammonia transfer rate was established.By the results of experiments,influence of mass-transfer rate in different aeration conditions and solution height was analyzed.
