氧氯化锆生产中放射性废水排放的监管

Environmental Supervision of Radioactive Waste Water Release during Zirconium Oxychloride Production

锆行业涉及的部分物料中的伴生放射性核素浓度较高,其中伴生的放射性商业利用价值不大,但其存在可能需要对生产环节的环境影响进行控制。氧氯化锆生产环节的废水排放是整个锆行业辐射环境监督管理需要关注的重点。梳理现状、分析不足,有利于该行业辐射环境管理的开展。对氧氯化锆生产环节的放射性废水排放情况进行了分析,指出了与当前辐射监管要求相悖的问题,提出了对放射性废水单独进行处理及制定锆行业废水排放的放射性控制标准等改进建议。

The concentration of associated radionuclides in some minerals and raw materials is relatively high in the zircon and zirconia industry,and it is too small to be of commercial value. But its existence may require supervision and control by the regulatory body concerning the impact on the environment during the production. The radioactive waste water release during the production of zirconium oxychloride is the focus of radiation environment supervision of the whole zirconium industry. Combing the status quo and analyzing the peck points are beneficial to the development of the radiation environmental supervision of the industry. The discharge of radioactive waste water during zirconium oxychloride production was analyzed,and the problems in the environmental supervision of radiation were reviewed.Some suggestions for improvement such as radioactive waste water treatment separately and standard formulation for radioactive control,were put forward in the end.
