摘要
室内空气中的苯系物对人体健康危害大。该文研制了基于吸附、催化和低温等离子体技术的净化室内苯系物的综合实验平台,平台由吸附/催化双功能材料模块、低温等离子体发生器、风道系统和控制系统构成,可长时间连续净化低浓度苯系物,实现吸附/催化材料的原地再生和无O_(3)二次污染的绿色目标。该平台提高了大气污染控制工程、环境综合实验等实验课程的高阶性、创新性、挑战度,有助于培养学生创新思维和解决实际工程问题的综合能力。
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 O_(3) 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.
