摘　　要：介绍了某低放射废水处理系统改造中的废水源项、处理目标、难度分析和措施,以及工艺系统和配套设施的改造内容。在原有工艺设施基础上,通过化学沉淀、蒸发和离子交换工艺的联合运用,使处理后废水的总α<1 Bq/L,总β<10 Bq/L,满足《污水综合排放标准》(DB 31/199—2009)。同时采用工艺自动化控制、辐射屏蔽和送排风等措施,获得了满足国家相关法规规定的低放射性废水输送、暂存和处理等要求的工艺系统,为低放射性废水处理提供了一种长期、有效的解决措施。The pollution source, wastewater treatment targets, difficulty analysis and measures in the upgrade project of a low-level radioactive wastewater treatment system as well as the process system and auxiliary facilities were presented. Based on the existing process facilities, through the combined use of chemical precipitation, evaporation and ion-exchange processes, the specific activities of treated water were less than 1 Bq/L for alpha emitters and less than 10 Bq/L for beta emitters, which meet the Inte- grated Waztewater Discharge Standard （DB 31/199 -2009）. Automatic control system, radiation shiel- ding and air ventilation system were designed for the transportation, interim storage and treatment of the low-level radioactive wastewater. Upgraded system provides a long-term and effective solution for the treatment of low-level radioactive wastewater.
