摘　　要：通过中试设备,以聚合氯化铝(PAC)作为混凝剂,研究活化硅酸助凝效果,以及在投加助凝剂的情况下,分别投加活性炭和高锰酸钾作处理,对比分析两种预处理方式对原水的处理效果。结果表明:投加活化硅酸能明显提高出水水质,且在相同出水水质情况下,投加活化硅酸能明显降低混凝剂使用量;在该原水中,随着活性炭投加量的增加,水中浊度,COD_(Mn),UV_(254),嗅阈值(TON)均明显降低,而随着高锰酸钾投加量的增加,对浊度,COD_(Mn),UV_(254)的去除效果一般,仅对嗅阈值有较好的去除效果。The coagulant effect of activation silicate on pilot equipment was studied by using polyaluminum chloride(PAC)as coagulant.And with adding activation silicate and PAC,study and do a comparative analysis the pretreatment effect of activated carbon and potassium permanganate.The results shows that:activated silicic acid can improve water quality significantly and decrease the dosage of PAC;with increase of activated carbon’s dosage,turbidity,COD_(Mn),UV_(254),threshold odor number(TON)of water are significantly decrease,but with increase of potassium permanganate,the removal effect of turbidity,COD_(Mn),UV_(254)are not very good except threshold odor number.
