| 摘 要： | 目的]减少酱油废水给环境带来的污染,降低酱油废水深度处理的费用。方法]采用曝气生物滤池对酱油废水2级好氧处理出水进行深度处理,研究其性能特点和影响因素。结果]不同气水比对废水COD去除效果的影响要大于对色度、浊度去除的影响;不同水力负荷对COD、色度的去除均有一定影响,色度的去除随水力负荷的增加去除率有所下降,当水力负荷为0.51m3/（m2·h）时对污染物的去除效果最为理想;废水色度和COD去除率与填料层高度的关系为随高度增加而升高,在100cm处对废水色度和COD去除率达到64.4%和58.4%。结论]曝气生物滤池以陶粒-海绵铁混合填料可以很好地去除酱油废水2级好氧出水中的色度和浊度,进一步降低废水COD,在气水比为2∶1、水力负荷为0.51m3/（m2·h）时对各种污染物的效果最好。
