【摘要】 核能作为一种清洁的一次能源,其应用越来越广泛。但随着核工业的不断发展,核废物的产生也源源不断。核废物又称放射性废物,其毒性只能按照固有的规律衰变到无毒水平,无法通过现有的技术手段进行消除。因此实现放射性废物的安全处置,是目前核能发展中十分重要的一个问题。此外,核工业废水中会含有一定量的尿素,如果不经过处理直接进行后续的废物处置,有可能会对设备产生一系列的影响,因此优先对其进行降解处理是十分必要的步骤,能够降低后续处理成本,以及提高废物处理的效率。本文对放射性废水的来源、分类及危害进行了简要的介绍,同时总结了几种尿素的降解方法。以期对未来核工业废水中尿素的去除提供一定的方法。更多还原

【Abstract】 As a kind of clean primary energy,nuclear energy is more and more widely used. However,with the continuous development of the nuclear industry,the generation of nuclear waste has also continued. Nuclear waste is also called radioactive waste. It’s toxicity can only decay to a non-toxic level in accordance with the inherent laws,and cannot be eliminated by existing technical means. Therefore,achieving the safe disposal of radioactive waste is a very important issue in the development of nuclear energy. In addition,the nuclear industry wastewater will contain a certain amount of urea. If the subsequent waste disposal is directly carried out without treatment,it may have a series of impacts on the equipment. Therefore,it is a very necessary step to give priority to its degradation treatment,which can reduce Follow-up treatment costs,and improve the efficiency of waste treatment.This article briefly introduces the source,classification and hazards of radioactive wastewater,and also summarizes several urea degradation methods. In order to provide a certain method for the removal of urea in nuclear industry wastewater in the future.更多还原
