摘　　要：研究了不同类型杀菌剂对腐生菌(TGB)和硫酸盐还原菌(SRB)的最低抑菌浓度(MIC)受Na+、Ca2+、Mg2+的影响。结果表明:非离子型杀菌剂异噻唑啉酮受阳离子影响最小,Na+对单季铵盐1227影响很小,但Ca2+、Mg2+对单季铵盐、双季铵盐、有机胍、季盐THPS等阳离子型杀菌剂和非离子型杀菌剂戊二醛影响都很大,可使其MIC增加数十倍,甚至上百倍。It is studied that Na^＋, Ca^2＋, Mg^2＋ have influence on minimum inhibitory concentration （MIC） of total growth bacteria（TGB） and sulfate-reducing bacteria（SRB） by using different types of bactericides. The results show that non-ionic isothiazolin-ketone （CMIT/MIT） is affected the least by cations ,and Na^＋ has little influence on single quaternary ammonium salt 1227. However, Ca^2＋ and Mg^2＋ have great influence on quaternary ammonium salt, organic guanidine,quaternary phosphonium salt （THPS）,glutaraldehyde,etc. ,which could enhance the MIC to dozens of times or even a hundred times.
