摘　　要：对茂石化炼油厂循环水用杀生剂MN - 2 0 2的杀菌性能进行了实验室静态模拟 ,并与新洁而灭进行了研究比较 ,表明前者是一种广谱、高效、低毒的杀生剂 ,对水中不同的菌种 :异养菌、硫细菌、硫酸盐还原菌 ,MN -2 0 2的杀菌效果略好于新洁而灭 ,且随浓度、作用时间不同又有其特点。在投配浓度为 2 0mg/L时 ,杀菌效果良好。Experiments about static simulation of microbicide MN-202 and Xinjiermiing to treat recycling water in refinery have been carried out.The results show that MN-202 is a widely used,higher efficient and lower toxic microbicide.MN-202,compared with Xinjiermie,has better performancc especially for heterotrophs bacteria,sulfobacter and dedulfurella. Each of them has their own features depending on concentration of microbicideand and contact time.MN-202 when its concentration is 20mg/L can kill bacteria and save microbicide.
