摘　　要：基于放射性废气净化的特殊性和必要性,对核电站不同类型的放射性废气的治理工艺进行了调研,分析了各工艺的优缺点。结果表明:吸附分离法对于各类放射性废气治理均具有较好的适用性,且设备及运行成本相对较低,研制出优选的吸附剂和吸附装置是该技术的改进方向;湿法吸收可用作吸附分离前端废气中气、固污染物的预处理,能延长吸附剂的使用寿命;废气净化新技术要面向安全、高效与非能动的方向发展。Investigation on purification techniques for different radioactive gaseous waste from nuclear power plant has been carried out based on its particularity and necessity. The characteristic of each technology was analyzed in detail. The results show that the adsorption method is feasible to capture all kinds of radioactive species from gaseous waste, due to both the equipment investment and operating cost are relatively low. In the improvement of adsorption technology, the goal should be to develop high-efficiency adsorbent and adsorbed. In order to increase the service life of adsorbent, the wet process absorption technology can be utilized for pretreating the gaseous and solid waste. The future development of purification techniques on radioactive gaseous waste should be safer, efficient and passive.
