Improving the safety inspection level of university laboratories is an important guarantee for preventing risks, and protecting the safety of teachers and students’ lives and property. In view of the problems existing in the routine safety inspection of university laboratories, such as lack of full-time safety inspection personnel, insufficient professional ability to identify safety risks. The mechanism construction, qualification certification, work priorities, workflow and cases of the third-party security inspection mechanism are introduced. And The professionalism, fairness and independence of laboratory security inspection are ensured by taking advantage of multiple entities. The new mode of third-party security inspection can improve the safety management level, and safeguard the discipline construction and high-quality talent cultivation.

Benzene toluene ethylbenzene & xylene (BTEX) in indoor air has significant harm for human health. This paper designs an experiment platform for alternating adsorption-enhanced catalytic treatment of BTEX by plasma. The experiment platform consists of adsorption/catalysis dual-function module, low-temperature plasma generation module, pipeline system and control system. The development of the experiment platform achieves the green goal of continuous control of low concentration BTEX for a long time without O₃ secondary pollution. The teaching application of the platform enriches the form and content of experimental courses such as air pollution control engineering and environmental comprehensive experiment, and helps to cultivate students′ innovative thinking and comprehensive ability to solve practical engineering problems.
