MBBR宋向阳(郑州市自来水总公司,河南郑州450013) : 采用移动床生物膜反应器(MBBR)与陶粒生物滤池(BF)预处理受污染黄河源水。结果显示,MBBR和BF均能有效去除水中的天然有机物(NOM)、藻类和藻毒素等污染物,并有效降低了消毒副产物生成势;MBBR和BF对CODMn和TOC的去除效果相当,但就不同性质的有机物而言,易生物降解的小分子有机物更容易被去除;BF对三氯甲烷前体物的去除效果高于MBBR,对藻类的去除效果则相近;BF与MBBR均表现出较好的去除微囊藻毒素的能力,去除率分别为56%和63%。MBBR和BF作为生物预处理工艺,能较好地去除常规工艺难以去除的有机物,可保障供水水质安全。 : 黄河源水; 生物预处理; 移动床生物膜反应器; 陶粒生物滤池:TU991 :A :1000-4602(2008)17-0012-04PretreatmentofPollutedYellowRiverSourceWaterwithMoving-bedBiofilmReactorandCeramsiteBiofilterSONGXiang-yang(ZhengzhouWaterSupplyCorporation,Zhengzhou450013,China) Abstract: ThepretreatmentofpollutedYellowRiversourcewaterwascarriedoutusingmoving-bedbiofilmreactor(MBBR)andceramsitebiofilter(BF).TheresultsshowthatMBBRandBFcanef-fectivelyremovenaturalorganicmatters(NOM),algae,algaetoxinsandotherpollutantsinwater.Theycanalsoreducetheformationpotentialofdisinfectionby-products.MBBRandBFhavethesameremovalefficiencyofCODMnandTOC,butforthedifferentorganicmatters,thebiodegradableorganicmatterswithsmallermolecularweightsareeasiertoberemoved.BFhashigherremovalefficiencyofchloroformprecursorsthanMBBR,andthesameremovalefficiencyoftotalalgaeasMBBR.BothBFandMBBRshowbetterremovalcapacityofmicrocystin,withtheremovalratesof56%and63%respectively.Asbi-ologicalpretreatmentprocesses,MBBRandBFcanstrengthentheconventionalprocess,ensuringdrink-ingwatersafety.
