The invention relates to a fluorine-containing hazardous waste stabilized solidified body. The solidified body is obtained through oxidative degradation and ion recombination reaction of a fluorine-containing hazardous waste raw material, a curing agent and a water mixture, the content of fluoride, cyanide, heavy metal and other harmful ingredients is within the national safety landfill pollution control standard range, and flexible landfill can be carried out. The invention further relates to a preparation method of the fluorine-containing hazardous waste stabilized solidified body. According to the method, the fluorine-containing hazardous waste is solidified and stabilized through a novel formula and technological operation conditions, the leaching toxicity of fluoride, cyanide, heavy metal and other harmful ingredients in the hazardous waste is greatly reduced, and the requirement for safe landfill is met. The method is simple in process, low in cost, small in equipment number and easy to implement.
本发明涉及一种含氟危废稳定化固化体，该固化体其由含氟危废原料与固化剂和水混合物经氧化降解及离子重组反应获得，其中氟化物、氰化物、重金属等有害成分的含量在国家安全填埋污染控制标准范围以内，可以进行柔性填埋。本发明还涉及上述含氟危废稳定化固化体的制备方法，该方法用新型配方和工艺操作条件对含氟危废进行固化稳定化，使危废中氟化物、氰化物、重金属等有害成分的浸出毒性大幅降低，满足安全填埋的要求。本发明工序简单，成本低廉，设备数量少，易于实现。
