摘　　要：针对核电厂废液中腐蚀产物的去除提出一种化学絮凝强化处理工艺。通过对配制胶体水样的定性定量分析，表明胶体形态可较好地模拟核电厂腐蚀产物源项。根据胶体的粒径分布（200～300 nm ）和含量特性（受pH值影响）进行絮凝剂（高分子聚合物与无机金属盐）选型和复配试验，结果表明：投加高分子聚合物B或高分子聚合物B＋无机盐Y后，对模拟废液絮凝净化效果较好（出水均达到工艺要求：去污因子DF＞50），但综合考虑胶体去除效率（絮凝反应时间），后续工程设计优先推荐絮凝剂B。Flocculation as an enhanced treatment process was put forward to remove corrosion products in liquid radwaste from nuclear power plant （NPP） .It is found that the prepared colloidal solution can simulate source terms of corrosion product in NPP through qualitative and quantitative analysis of water samples .Experiments of floccu-lant selection （polymer and inorganic salt ） were done focusing on colloidal particle size distribution （200-300 nm ） and content features （influenced by pH ） .Results indicate that both polymer B and B＋inorganic salt Y show better purification effect via floccula-ting （effluent met engineering requirements of DF 〉50） and flocculant B is recommen-ded in subsequent engineering design considering of removal efficiency （flocculation reaction time） of colloids .
