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 ,以达到提高杀菌效果的目的
The orthogonal experiment was used to study the bactericidal effect of improving the stability of chlorine dioxide bactericide to kill sulfate reducing bacteria. Four main factors affecting the bactericidal effect of the chlorine dioxide bactericide were determined and the influence of each factor on the bactericidal effect of the chlorine dioxide. The test results show that the stability of chlorine dioxide is a good disinfectant for oilfield injection water treatment. It has the characteristics of less dosage, quick sterilization and good bactericidal effect. It is a new type of bactericide for chlorine series bactericide renewal Agent. The increase of easily oxidizable matter in water will significantly reduce the bactericidal effect. The choice of activator and the entire activation process have a greater impact on the bactericidal effect of the chlorine dioxide bactericide. The bactericidal temperature can be adjusted by selecting the point of addition of the bactericide so as to achieve the purpose of improving the bactericidal effect
