中文摘要：

在生物安全管理的各环节中,感染性废弃物的处理是控制实验室生物安全的关键环节。为此,我国制定了关于感染性废弃物处理的法律、法规,以避免污染实验室或环境。本三级生物安全实验室运行的3年中,在处理感染性废弃物时遇到了若干需要认真对待的细节,如固体感染性废弃物处理过程中的灭菌环节、消毒剂使用对压力蒸汽灭菌器的损伤、液体感染性废弃物的灭菌模式等,并提出了解决措施和建议。

英文摘要：

Disposal of infectious waste is a pivotal step in biosafety management in laboratories.The Chinese government has issued constitutional laws and statutes on disposal of infectious waste for averting pollution.During our 3 years management of a biosafety level 3（BSL-3）laboratory,we encountered some contradictions in the disposal of infectious waste,including the package of solid infectious waste for sterilization and disposal,damage to the autoclave by disinfectant used in treating the waste,and disposal methods for liquid infectious waste.Additional experiences from our management of a BSL-3 laboratory are discussed.
