中文摘要：
结合国内外城市污泥处理现状，分析当前污泥处理过程中存在的主要问题。分别论述利用辐射技术处理城市污泥的2种方法：γ射线辐射法和高能电子束辐射法。对辐射技术的影响因素进行了归纳，主要包括污泥本身性质、剂量与辐照条件、基质环境。探讨辐射技术处理城市污泥的作用机理及效果，包括辐射杀灭微生物、改善污泥理化性质、提高污泥的稳定性等。最后总结污泥辐射处理技术面临的问题并对其发展前景进行展望。
英文摘要：
Problems encountered in the urban sludge treatment were analysed by combining the recent status of the sludge treatment in China and abroad. Gamma-radiation and electron beam radiation, two potential radiation technologies for the treatment of domestic sewage sludge, as well as some affecting factors including sludge properties, dose and radiation conditions, matrix environment, and etc. were expounded. Mechanisms and effects of the radiation technologies were discussed referring to inactivating microorganism, improving sludge physicochemical property and stability, and etc. Finally, faced problems and future development orientation of the radiation technologies for sludge treatment have been summed up.
