粉末活性炭和二氧化氯在长距离原水输水中除嗅研究 苏掂， 康雅， 王琰， 周全 (郑州自来水投资拉股有限公司，郑州，450007) 摘要：针对水厂原水长距离输送的工艺特征，研究了黄河中下游地表水体单独投加粉末活 性炭、单独投加二氧化氯以及两种水处理剂同时投加三种方法的除嗅效果．试验结果表明： 粉末活性炭投加量为10m#L接触2h时，臭阑值的去除率可迭到83．1％；二氧化氯投加为 药剂同时投加时，会产生抑制作用，对臭阈值的去除率不及单独投加粉末活性炭． 关键词：嗅味；粉末活性炭；二氧化氯；臭阈值 Odorin DistanceRawWaterTransmission RemovingLong PACand Pipelineby C102 Su Zhe，KangYa，WangYan，ZhouQuan Water (Zhengzhou Corporation,Zhcngzhou,450007) Supply in withthree as Abstract：TheremovalrateofOdor waterof ground Huanghe methods，such at PAC C102 and thetwowatertreatment same solelydosing agents times， dosingsolely,dosing results that were by distancelawwatertranmission test showsthe investigatedlong pipeline．The PACin in2h removalrateofodorswere ofresidence C102 83．1％bydosing X0mg／L time；adding in l 160min removalratesof werelittledifference and odors 0．5mg／L mg／L，in contactingtime，the than 50．2％and the ofPAC、Ⅳith insametimeswerewo培e 57．2％；and C102 by process adding PAC ofinteractionwitheachother． solely,because and Odor；PAC；C102；TON Keywords：Taste 目前国内许多地区饮用水水源都存在嗅味问趔1H4]，对饮用水品质带来很大影响。对
