曝气生物滤池对生活污水处理的试验研究

Experimental Study on Treatment of Domestic Sewage by Biological Aerated Filter

针对当前淡水资源短缺制约我国人民生活和经济发展的关键因素。在对曝气生物滤池工艺简单概述的基础上,针对曝气生物滤池处理工艺的填料选择提出原则,并以活性炭、混合以及碎石填料为重点研究对象,得出最佳填料和水力停留等指标;最后,采用相同思路对曝气生物滤池的填料高度、水力负荷等最佳工艺参数进行确定,可指导后续曝气生物滤池在工业中生活污水的应用。

In view of the key factors that restrict people's life and economic development in China due to the current shortage of fresh water resources.On the basis of a brief overview of the BAF process,the principles of filler selection for the BAF treatment process are proposed,and the optimal filler and hydraulic retention index are obtained by focusing on active carbon,mixed and gravel filler.Finally,the same idea is adopted to determine the best process parameters such as filler height and hydraulic load of BAF,which can guide the subsequent application of BAF in industrial domestic sewage.
