季铵盐与聚季铵盐复配对海生物杀灭性能的评价

Evaluation on the eliminating capacity of quaternary ammonium salt and polyquaternium composition for marine creatures

为了更好控制火力发电厂循环水系统中海生物的污染问题,针对单一非氧化性海生物杀生剂季铵盐类化合物存在泡沫多、杀生率低下、易产生抗药性等缺点,将单链季铵盐杀生剂AY1001与聚季铵盐杀生剂(A和B)进行复配,评价混合复配药剂体系对海生物的杀灭性能。结果表明:投加3 mg/L(AY1001+A)或3 mg/L(AY1001+B)作用24 h,效果优于同等浓度下单一杀生剂AY1001的效果。

The single chain quaternary ammonium salt（QAS） biocide agent AY1001 and polymeric QAS biocide agent（A and B） have been combined,in order to better control the marine creature pollution problem in the seawater circulation system of power plants,and aiming at their disadvantages,such as high foam,low eliminating rate and apt to produce drug resistance etc. The eliminating capacity of the mixed agent system for marine creatures is evaluated.The results show that the eliminating effect of adding 3 mg/L（AY1001＋A） or 3 mg/L（AY1001＋B） and reacting for24 hrs.,is better than that of single biocide AY1001 with the equal concentration.
