姜成春1, 马 军1, 王志军2, 张海龙2, 李圭白1(1.哈尔滨工业大学市政环境工程学院,黑龙江哈尔滨150090;2.哈尔滨市自来水集团公司,黑龙江哈尔滨150080)   : 烧杯试验和生产应用的结果表明,高锰酸钾与粉末活性炭联用对低温低浊微污染源水具有明显的强化处理效果,能显著降低滤后水浊度和高锰酸盐指数。但高锰酸钾与粉末活性炭的投加顺序对混凝效果有一定的影响,在投加混凝剂快速搅拌后再投粉末活性炭可取得很好的强化混凝效果。生产运行结果还表明,少量剩余高锰酸钾可被粉末活性炭还原,而后被混凝过程去除。  : 微污染源水; 高锰酸钾; 粉末活性炭:TU991.2  :A  :1000-4602(2001)03-0012-04CombinedProcessofPermanganateOxidationandPowderedActivatedCarbon(PAC)AdsorptionforRawWaterTreatmentwithLowTemperatureandLowTurbidityJIANGCheng-chun1, MAJun1, WANGZhi-jun2, ZHANGHai-long2, LIGui-bai1(1.SchoolofMunic.andEnviron.Eng.,HarbinInstituteofTech.,Harbin150090,China;2.HarbinWaterSupplyGroupCo.,Harbin150080,China)  Abstract: Jartestandfull-scaleapplicationdemonstratedthatthecombinedprocessofper-manganateoxidationandPACadsorptionwaseffectiveforenhancingtreatmentofmicro-pollutedrawwaterwithlowtemperatureandlowturbidity.TheCODMnandturbidityinfilteredwaterwerere-ducedsignificantly.ItwasobservedthatdosingsequenceofpermanganateandPACaffectedthecoagu-lationefficiencytosomeextent.SoundenhancementforcoagulationcouldbeachievedwhenPACwasaddedafterrapidmixingofcoagulant.Theresultsoffull-scaleoperationshowthatasmallamountofresidualpermanganatecanbereducedbyPACandremovedbycoagulationprocess.
