摘　　要：目的为了探寻更简便、易行的羊毛卫生处理方法。方法分别采用环氧乙烷熏蒸法和微波消毒法对打包羊毛进行消毒灭菌处理,使用菌片法检测消毒灭菌效果。结果在环氧乙烷熏蒸处理试验中,当作用时间、温度、相对湿度恒定的条件下,环氧乙烷浓度高于临界值时,消毒效果可达到要求。在同样环境条件下,熏蒸浓度低于临界值,消毒效果达不到要求。当熏蒸浓度、温度、相对湿度恒定的条件下、作用时间对环氧乙烷的消毒效果有明显的影响。作用时间低于临界值时,不能达到消毒灭菌要求,但延长一定作用时间,可达到消毒灭菌要求。在微波消毒试验中,当温度、相对湿度恒定时,经700W微波照射12min,对羊毛中菌片杀灭率可达99.99%。结论环氧乙烷熏蒸消毒羊毛处理效果好,但作用时间长、环境条件要求严格。而微波消毒处理羊毛快速、环保,在短时间内可有效杀死细菌芽胞。在口岸卫生处理工作中,可研究推广更多的处理方法,提高卫生处理工作质量和效率。Objective In sing epoxy ethane fumigati order to seek a more simple and easier sanitary method to deal with wool. Methods U on and microwave sterilization method respectively to deal with the packed wool in a dis infection and sterilization way and use of bacteria method to test the effect. Results In the epoxy ethane fumiga tion experiment, under the same time, temperature, relative humidity conditions, the disinfection requirements can be achieved when the epoxy ethane thickness is higher than the threshold limit value （TLV）. In the same environ mental conditions, the disinfection requirements can not be achieved when the epoxy ethane thickness is lower than the threshold limit value （TLV）. Under the same epoxy ethane thickness, temperature, relative humidity, the time has apparent effect on the effect. The time is less than the limited one, the disinfection requirements can not be a chieved. But by extending the time, the requirements can be achieved. In the microwave disinfection tests, under the same temperature, relative humidity, by using 700W microwave irradiation for 12min, the killing rate about the fleece of bacteria can reach 99.99%. Conclusion Ethylene oxide is a very effective method for dealing with the wool, but the time is long and the environment condition is strictly needed. And microwave sterilization method can deal the wool in a fast and environmental way. During the sanitation work on the port, we can search more methods to improve the quality and efficiency of sanitary work.
