摘　　要：铁污染软化水用树脂常用复苏剂是盐酸。为使树脂充分复苏，需用浓度高达１０％ＨＣＩ溶液浸泡树脂。作者用氯化氢—氯化钠—亚硫酸钠混合溶液作复苏剂，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，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 resin by iron is hydrochloric acid. In order to fully resuscite, the percentage of hydrogen chloride in hydrochloric acid is as high as 10%. This paper introduces a mixed solution of HCl-NaCl-Na 2SO 3 as resuscitative agent, in which these percentages of components are 4%, 4% and 0.08% respectively.
