应用正交试验方法 ,对提高稳定性二氧化氯杀菌剂杀灭硫酸盐还原菌的杀菌效果进行了试验研究。确定了影响稳定性二氧化氯杀菌剂杀菌效果的 4个主要因素以及各因素对稳定性二氧化氯杀菌效果的影响程度。试验结果表明 ,稳定性二氧化氯是一种良好的油田回注水处理用杀菌剂 ,它具有用量少、杀菌速度快、杀菌效果好等特点 ,是氯系列杀菌剂更新换代的一种新型杀菌剂。水质中易氧化物含量增加会显著降低其杀菌效果。活化剂的选择和整个活化过程对稳定性二氧化氯杀菌剂的杀菌效果也有较大的影响 ,可以通过选择杀菌剂投加点来调节杀菌温度 。

This paper discusses an experimental study for improving the germicidal efficacy of stabilized chlorine dioxide by orthogonal trial method. The four main influential factors of germicidal efficacy of stabilized chlorine dioxide and their affect are determined. Experimental result shows that stabilized chlorine dioxide is a new type of bactericide that replaces the chlorine bactericide series. It has the characters of less dosage, rapid sterilization and high germicidal efficacy. The germicidal efficacy would markedly decrease with oxidized compound increased in the treated water. The type of activator and the activation process also greatly affect the germicidal efficacy. Furthermore, the delivery position of bactericide can regulate the sterilization temperature, which can improve the germicidal efficacy of the stabilized chlorine dioxide.
