摘　　要：铁污染软化水用树脂常用复苏剂是ＨＣｌ。为使树脂充分复苏，需用浓度高达１０％ＨＣｌ溶液浸泡树脂。本法用ＨＣｌ－ＮａＣｌ－Ｎａ２ＳＯ３混合溶液作复苏剂，各组份浓度依次为４％、４％、０．０８％，能快速使树脂充分复苏。酸浓度低、腐蚀性弱，所以对国内现有的小型软化水系统更为适用。The common resuscitative agent for polluted cation exchange resins by iron is hydrochloric acid. In order to fully resuscite them, high concentration solulion with 10% HCl must be used. This paper introduces a mixed solution of HCl-NaCl-Na 2SO 3 as resuscitative agent, their component concentration being 4%, 4% and 0.08% respectively.
