摘要:在国内某台年产5万t卫生纸机上进行了一种新型弱氧化型杀菌剂的应用，并与传统杀菌剂进行了应用效果对比。结果表明，该类弱氧化型杀菌剂相比传统杀菌剂有明显优势，能使造纸系统中的细菌、真菌等微生物数量显著降低，微生物得到很好的控制，体系变得更干净。与在其他纸种上的应用相比，该类型杀菌剂用于卫生纸机微生物控制时，控制效果与预期还有差距，这可能是由于卫生纸生产过程中采用了较低的上浆浓度，相同吨纸杀菌剂用量的有效浓度偏低导致的。

Abstract:A new weak-oxidation bactericide was applied on a domestic toilet paper machine with an annual output of 50000 tons， and its application effect was compared with the traditional bactericide. The results showed that the weak-oxidation bactericide had obvious advantages in comparison with the traditional bactericide and could be used to significantly reduce the number of microorganisms like bacteria and fungi in the papermaking system. The microorganisms were well controlled and the system became cleaner. Compared with the application in other kinds of paper， the effect of this weak-oxidation bactericide used for the microbial control of toilet paper was still lower than expected. It may be due to the lower pulp concentration used in the production process of toilet paper， which resulted in the lower effective concentration of bactericide for the same amount of paper.
