4) degree of depth maintenance: the cement solidification thing tentatively condensed is carried out degree of depth maintenance;
5) landfill: by the cement solidification thing security landfill after degree of depth maintenance;
6) repeatedly wash: by the bulky grain flying dust elder generation that formed in step 1) and aqueous solution, by repeatedly washing, precipitating, form supernatant and solidliquid mixture;
7) Separation of Solid and Liquid: solidliquid mixture is separated and forms solidfied material and liquid;
8) precipitation of heavy metals: liquid reach a certain amount of after, add heavy metal complexing agent and make heavy metal precipitation, by heavy metal stabilization landfill after filtration;
9) evaporation process: the liquid of solid-liquid separation is carried out evaporation process, obtains distilled water and salt;
10) dry: drying is carried out to the solidfied material formed in step 7);
11) extruder grain: carry out extruder grain to dried solidfied material, forms shaping haydite blank;
12) constant-temperature moisture-keeping maintaining: to shaping haydite blank constant-temperature moisture-keeping maintaining.
