摘要
为使放射性科研实验产生的低放废水满足国家排放的有关规定,实现废物的最小化,减少排放量,新建了一套低放废水的处理装置,工艺设计考虑了处理含多种核素废水的适用性、经济性、运行维修简捷性,引入超滤膜处理的新技术,采用絮凝、超滤、离子交换相结合的间歇式处理工艺,并能实现离子交换循环处理的功能。装置建成后,进行稳定元素Co、Sr的模拟废水处理实验,结果表明,对Co去除率达到99%以上,Sr降到检测限以下,达到了废水处理要求和国家的排放规定。
In order to meet the national requirements for disposal of radioactive wastewater produced by scientific research,a device was constructed for wastewater concentration and volume reduction.The applicability,cost and simplicity of maintenance were considered for designing the device,into which a new technology of ultrafiltration membrane treatment was introduced.The combination of methods of flocculation,ultrafiltration（UF）,ion exchange treatment and re-treatment was adopted.The device was tested for commissioning using stable elements of Co and Sr.The results show that the removal percentage of treatments is achieved more than 99% for Co,and non-detectable level for Sr,in accordance with the national requirements for removal percentage of treatments and wastewater discharge regulations.
