聚合氯化铝铁对低温低浊海水混凝效果的影响聚合氯化铝铁对低温低浊海水混凝效果的影响刘伟,程方,刘振耒,李晓殷(天津城市建设学院环境与市政工程学院,天津300384)摘要:采用聚合氯化铝铁(PAFC)对低温低浊海水进行混凝烧杯试验。结果表明,在海水水温低于10℃、浊度低于50NTU时,PAFC的最佳投药量为15mg/L,此条件下浊度、CODMn及UV254的去除率分别达到91.57%,54.47%和32.56%。通过试验比较了PAFC和聚合氯化铝(PAC)对低温低浊海水的混凝效果,得出PAFC的混凝效果优于PAC。关键词:混凝;低温低浊海水;聚合氯化铝铁;聚合氯化铝中图分类号:TU991.2文献标志码:A文章编号:1673-9353(2012)06-0020-03doi:10.3969/j.issn.1673-9353.2012.06.006InfluenceonthecoagulationofPAFCfortreatinglowtemperatureandlowturbidityseawaterLiuWei,ChengFang,LiuZhenlei,LiXiaoyin(SchoolofEnvironmentalandMunicipalEngineering,TianjinInstituteofUrbanConstruction,Tianjin300384,China)Abstract:Thecoagulationjartestwasconductedfortreatinglowtemperatureandlowturbidityseawaterbypolymericaluminumferricchloride(PAFC).Theresultsshowedthattheoptimalchemicaldosagewas15mg/Lwhenseawatertemperaturewasbelow10℃andturbiditywasbelow50NTU,andtheremovalratesofturbidity,CODMnandUV254reached91.57%,54.47%and32.56%respectivelyunderthiscondition.ThecoagulationofPAFCandpolyaluminumchloride(PAC)onlowtemperatu
