摘要: 采用小型反渗透装置,对反渗透处理模拟含硼放射性废水的性能进行实验研究。结果表明:提高废水的pH值、增大操作压力和降低回收率都可以改善反渗透对硼酸、放射性核素和盐分的截留效果,尤其以提高pH最为显著。当调节模拟废水的pH至9.0以上时,反渗透处理能够将出水中的硼浓度降低到5 mg/L以下,同时对模拟放射性核素铯和钴有很好的截留效果。

Abstract: Experiments were carried out on a pilot equipment to study the performance of treatment of simulated boron containing radioactive wastewater by reverse osmosis membrane.Results showed that the rejection efficiency of boron,simulated nuclides and salts in simulated wastewater could be enhanced by increasing the feedwater pH,improving the applied pressure or reducing the recovery ratio.By adjusting the simulated wastewater pH to 9.0,the boron concentration in permeate could be lower than 5mg/L and two nuclides including cobalt and cesium could be removed to a satisfied extend.
