核工业废水是一种具有微量放射性的高盐度废水，对核工业废水的治理仍是世界各国未能解决的难题。本文提出采用低温蒸发技术处理核工业废水，研究了蒸发温度、压力、浓缩倍数以及单次加料体积对核工业废水的CODCr、氯离子浓度以及TDS去除率的影响，确定了最佳浓缩倍数、单次加料体积等工艺参数。实验结果表明：用蒸法技术处理核工业高盐度废水是可行的，核工业废水蒸发浓缩到可以结晶时的蒸发出的冷凝液中不含放射性物质，其水质能够达到废水排放或部分回用水的水质要求，结晶出的固体废物可采用固化技术进行处理，可彻底解决核工业废水对环境的污染。

Nuclear industry wastewater is a kind of high slinity wastewater with trace -level radio activity . It is still an unsolved problem to treat nuclear industry wastewater all over the world .This paper put forward to using low -temperature evaporation to treat nuclear industry wastewater and studying the effect to CODCr、chloride ions concentration and TDS of condensate by evaporation temperature、evaporation pressure、multiple of concentration of wastewater .It is feasible to treat nuclear industry wastewater by evaporation means , because the distillate is still meet the wastewater discharge criterion or criterion of some reuse water when the wastewater is concentrated to the situation that the condensate can form crystal .The crystal can be solidified using cement . This method has solved thoroughly the pollution from nuclear industry wastewater to environment .
