摘　　要：通过静态阻垢试验研究了PBTCA和HEDP在低温条件下(2~15℃)的阻碳酸钙垢性能。结果表明:PBTCA和HEDP在2~15℃下的阻碳酸钙垢性能良好。初始钙离子+碱度对PBTCA和HEDP的阻垢性能影响较大,当钙离子+碱度从(500+600)mg/L提高至(800+800)mg/L时,PBTCA和HEDP的阻垢率从100%分别降至65%、60%。PO_4^(3-)、Zn^(2+)和浊度等的存在对PBTCA和HEDP阻垢效果的影响较小。By static experiments,the calcium carbonate scale inhibition capability of PBTCA and HEDP under low temperature conditions（at 2-15 ℃） has been investigated. The results show that PBTCA and HEDP have good scale inhibition capability for calcium carbonate at 2-15 ℃. The initial Ca2＋ and alkalinity have comparatively great influence on the scale inhibition capability of PBTCA and HEDP. When Ca2＋ ＋alkalinity concentration increases from（500＋600） mg/L to（800＋800） mg/L,the scale inhibition rate of PBTCA is dropped from 100% to 65% and the scale inhibition rate of HEDP is dropped from 100% to 60%. The presence of PO43-,Zn2＋,turbidity,etc. has less influence on scale inhibition effect.
