放射性废物治理浅析——以广东省某稀土厂为例

The Simple Analysis of the Radwaste Treatment——A Case Study of a Rare Earth Mineral Factory in Guangdong Province

稀土矿是放射性伴生矿,其生产过程中产生的废渣伴有较强的放射性,属于危险废物,需要妥善处理。本文以广东某稀土厂为例,总结放射性较高的优溶渣、镭渣的处理措施,按照国家和地方环境保护法律、法规的要求,提出这些废渣及在处理废渣过程中产生的废水的最终处理方式。分别为:综合利用后剩余废渣进行暂存,镭渣经水泥固化后送坑道封存,增加重晶石吸附(除镭)工序,降低废水中的总α、β。通过这些治理,实现明显的环境效益和社会效益。

The rare earth mineral is radioactive associated ore, the waste solid created in the process of producing which usually have intense radioactivity and belong to the hazardous wastes, so it＇s need to be properly disposed. This paper takes one of rare earth factories in Guangdong province as example, to summarize the disposal measures about the preferential solution waste solid and the radium waste solid which have much more intense radioactivity. According to the national and local environmental. legislation,the ultimate disposal measures of the waste solid and the waste water which produced in the process of the waste solid disposing is put forward. It included that the preferential solution waste solid put to temporary storage, the radium waste solid sent to tunnel after solidifying with cement, in order to reduce concentration of total α, β, added the process of adsorption using barite. With these treatments, carrying out the obvious environmental benefits and social benefit.
