北京大学实验室危险化学废弃物暂存研究

北京大学作为争创世界一流大学的中国高校,教学科研工作量突飞猛进,随之实验室危险废弃物(以下简称:危废)产量大幅增长。如何保证这些危废在校期间的安全暂存,成为全校实验室安全管理和环保工作的重要内容。北京大学根据性质的不同对危废进行了分类管理,优化改进了实验室危险化学废弃物暂存柜结构;对暂存环境中挥发的VOCs进行了监测,并利用二氧化钛纳米线光催化剂对污染气体进行了净化测试研究。结果发现所有检测到的污染成分都能被光催化技术净化消除,显示出光催化技术是一种很有潜力的VOCs净化手段,可用于解决校园危废的复杂VOCs污染问题。

Study on the Temporary Storage Method of Hazardous Chemical Waste in Laboratories of Peking University

Peking University, striving to be a top university in world, has made rapid progress in research and teaching, resulting in the subsequent increase in the production of hazardous waste in laboratories. How to ensure the safety and temporary storage of these hazardous wastes during campus hours has become an important part of the laboratory safety management and environmental protection work. We manage the hazardous waste by classification according to its different natures. We have also optimized the structure of the cabinet for temporary storage of hazardous chemical waste. The VOCs volatilized in the temporary storage environment were monitored, and the purification test of the polluted gas was carried out by using the titanium dioxide nanowire photocatalyst. It was found that all detected pollutants could be degraded by the catalyst, which showed that photocatalytic technology is a promising method used to solve the complex VOCs pollution problem in campus hazardous waste temporary storage.
