曝气生物滤池(BAF)用于建筑中水处理试验研究

曝气生物滤池是一种介于生物接触氧化法与生物流化床之间的生物膜污水处理工艺,其紧凑性、能耗及运行维护亦介于两者之间,非常适合用于建筑中水处理。为检验曝气生物滤池处理建筑中水的性能,分别采用人工配水和洗浴废水进行了试验测定和实际验证。验证试验表明,经曝气生物滤池处理后的洗浴废水几乎不需任何后续处理(混凝、沉淀、过滤)便可满足中水回用标准要求。

Experimental study of BAF treating building grey-water for reuse

Biological aerated filter(BAF)is a process of biofilm between bio-contact oxidation process and biological fluidized bed for wastewater treatment,which is especially suitable for build- ing grey-water treatment.In order to evaluate the general performance of BAF,a pilot experiment with a single stage up-flow BAF was initiated with synthetic wastewater,and then the practical behaviors of the BAF were testified using bathing wastewater.The experiment using bathing wastewater demonstrated that the BAF could remove pollutant effectively without any post-treat- ment processes such as coagulation,sedimentation and filtration unit.The treated bathing wastewater could meet the needs for current reused water quality standard.
