摘　　要：目的筛选能够有效杀灭氦氧饱和潜水舱室中真菌的消毒剂。方法采用悬液定量杀菌试验,测定4种常用消毒剂对氦氧饱和潜水环境中分离的9株真菌的杀灭效果。利用综合评分法从中筛选出最佳的消毒剂以及最佳的处理时间。结果 0.3%二癸基二甲基溴化铵溶液消毒效果最好,作用10 min对真菌杀灭对数值均达到3以上,最佳消毒处理时间为30 min;其次为0.2%醋酸氯已定溶液;0.4%苯扎溴铵溶液和0.4%过硫酸氢钾溶液对真菌消毒基本无效。结论 0.3%二癸基二甲基溴化铵溶液处理30 min具有良好的杀真菌效果,能够用于氦氧饱和潜水舱室的真菌消毒。Objective To choose disinfectant that can effectively kill fungi in the cabin of heliox saturation diving. Methods Suspension quantitative germicidal test was used to determine the disinfection efficacy of four commonly used disinfectants to 9 strains of fungi isolated from the cabin environment of heliox saturation diving. The optimal disinfectant and treatment time were screened out by mixed-level orthogonal design and comprehensive evaluation method.Results Among four disinfectants,0. 3% didecyl dimethyl ammonium bromide solution had the best germicidal effect,the average killing logrithm value was above 3 for 10 minutes contact time. 0. 2% chlorhexidine acetate solution possessed lower germicidal effect of fungi,while 0. 4 % benzalkonium bromide solution and 0. 4% potassium monopersulfate solution had almost no effect to fungi. Conclusion 0. 3% didecyl dimethyl ammonium bromide solution exhibited excellent anti-fungus effect in 30 min and could be used for the cabin of heliox saturation diving disinfection.
