Preparation method of steel slag-based curing agent and treatment system and method of Cd polluted soil
The invention discloses a preparation method of a steel slag-based curing agent and a treatment system and method of Cd-polluted soil. The preparation method comprises the following steps: weighing desulfurized gypsum and steel slag for later use; and fully and uniformly mixing the desulfurized gypsum with steel slag to obtain a curing agent for heavy metal polluted soil; a Cd polluted soil treatment system comprises a treatment unit located on a crawler excavator and a film covering unit located on a soil pressing machine, and the treatment unit comprises an excavator master control room, anexcavator master operation table, a first excavator arm and a second excavator arm; The Cd polluted soil treatment method comprises the following steps: putting a prepared curing agent into a curing agent storage tank; controlling a ground breaking stirrer to break and crush the Cd polluted soil through the excavator arms; spraying mixed curing agent powder of the steel slag and the desulfurized gypsum and water into the soil. The preparation method of the curing agent adopts industrial waste residues, and is green, environment-friendly, economical, wide in source, easy in material obtaining and simple and easy in preparation mode.
本发明公开一种钢渣基固化剂制备方法及Cd污染土的处理系统及方法,称取脱硫石膏和钢渣备用；将上述脱硫石膏与钢渣充分混合均匀，得到重金属污染土壤固化剂；一种Cd污染土处理系统，所述处理系统包括位于履带式挖掘机上的处理单元和位于压土机上的覆膜单元，处理单元包括挖掘机总控制室、挖掘机总操作台、第一挖机臂和第二挖机臂；一种Cd污染土处理方法，所述处理方法包括以下步骤：将权利要求中制备的固化剂装入固化剂储存罐中；通过挖机壁控制破土搅拌器对Cd污染土进行破土粉碎；将钢渣和脱硫石膏混合固化剂粉末及水喷入土中。本发明固化剂制备方法均采用工业废渣材料，绿色环保，经济且来源广泛，易于取材，制备方式简单易于实现。
