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(BAF)用于建筑中水处理试验研究·建筑给排水·曝气生物滤池(BAF)用于建筑中水处理试验研究仇付国郝晓地陈新华(北京建筑工程学院可持续环境生物技术研发中心，北京100044)摘要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。关键词洗浴废水曝气生物滤池(BAF)生物膜建筑中水处理ExperimentalstudyofBAFtreatingbuildinggrey。waterforreuseQiuFuguo，HaoXiaodi，ChenXinhua(TheR&DCenterforSustainableEnvironmentalBiotechnology。BeijingInstituteofCivilEngineeringandArchitecture，Beijing100044，China)Abstract：Biologicalaeratedfilter(BAF)isaprocessofbiofilmbetweenbio-contactoxidationprocessandbiologicalfluidizedbedforwastewatertreatment，whichisespeciallysuitableforbuild—inggrey—watertreatment．InordertoevaluatethegeneralperformanceofBAF，apilotexperimentwithasinglestageup—flowBAFwasinitiatedwithsyntheticwastewater，andthenthepracticalbehaviorsoftheBAFweretestifiedusingbathingwastewater．TheexperimentusingbathingwastewaterdemonstratedthattheBAFcouldremovepollutanteffectivelywithoutanypost—-treat
