厌氧膜床处理小型餐饮废水的启动研究白中炎,胡勇有,黄瑞敏,梁辉强(华南理工大学造纸与环境工程学院环境工程系,广东广州　510640)　　[摘要]厌氧膜床最大的特点是用立体填料代替了传统的小粒径填料,首次以厌氧膜床处理小型餐饮废水的启动为研究对象,以满负荷的1/8,2/8,4/8,8/8逐步提高容积负荷,经过85d的启动运行,反应器达到满负荷。研究结果表明:进水pH较低,平均为5.06,经过厌氧膜床启动,出水在6.7左右;COD的去除率稳定在50%左右;启动后期的污泥上浮可能是颗粒污泥形成的预兆。　　[关键词]厌氧膜床;餐饮废水;启动　　[中图分类号]X703.3　[文献标识码]B　[文章编号]1005-829X(2003)05-0041-03Studyonthestart-upofthespecialanaerobicfilterbedfortreatingsmallscalerestaurantwastewaterBaiZhongyan,HuYongyou,HuangRuimin,LiangHuiqiangllegeofPaperandEnvironmentEngineering,SouthChinaUniversityofTechnology,Guangzhou510640,China)Abstract:TheSpecialAnaerobicFilterBed(SAFB)isanewtypeofanaerobicbioreactor.Itischaracteristicofusingspatialfiltertoreplacethetraditionalfilterwhosediametersaresmall.Thestart-upofSAFBfortreatingsmallscalerestaurantwastewaterisstudiedforthefirsttime.Thevolumetricalloadingisgraduallyimprovedby1/8,2/8,4/8and8/8offullloading.Thestart-upperiodis85days.TheresearchresultsshowthattheperformanceofSAFBforsmallscalerestaurantwastewatertreatmentisfeasibl
