摘　　要：与开放空间相比,地下工程内空气氡含量较高,为保障内部工作和生活人员的身体健康,需进行环境空气降氡处理。目前活性炭吸附技术及静电除尘技术为地下工程局部降氡的主要技术。为保证除氡效率,活性炭吸附设备存在占地过大、能耗过高等问题,而静电除氡技术只能去除环境中未结合态氡子体,对氡气浓度及结合态氡子体无影响。通过对现有技术的介绍和对比,对新型金属有机骨架(MOFs)材料及气体膜分离组件在地下工程局部降氡的可行性进行了分析。The radon concentration is higher in the underground facilities than in the open space.In order to protect people who live or work in the underground space from radiation hazard,the radon reduction practice has become a necessity.Presently,active carbon radon adsorption technique and electric radon elimination technique are the two main techniques used in the radon reduction area.Active carbon adsorption device would take too much space and be high energy consumption when high efficiency was needed.Electric radon elimination technique had high efficiency in eliminating combined type radon decay products,but it had no influence on the concentration of radon and uncombined type radon decay products.Based on the present technique,metal-organic frameworks(MOFs)and membrane gas separation module were introduced and the possibilities of these new materials and technique were also analyzed.
