Steel slag-based curing agent and application thereof in curing nickel-containing polluted soil
The invention discloses a steel slag-based curing agent and application thereof in curing nickel-containing polluted soil. The steel slag-based curing agent is prepared from the following components: steel slag powder, slag powder, gypsum, cement clinker, an exciting agent, calcium bentonite, ethyl xanthate and the like, is used for curing nickel-containing polluted soil, and is prepared through a physical adsorption-chemical adsorption-chemical complexing-physical wrapping mode; the steel slag-based curing agent can play a role in curing and stabilizing nickel from multiple dimensions, the in-situ space threshold of the heavy metal nickel is achieved, the migration rate of the nickel is greatly reduced, the nickel curing stability is enhanced, the main raw material adopted by the steel slag-based curing agent is solid waste, the purpose of treating waste with waste is achieved, and the steel slag-based curing agent has great economic and environment-friendly benefits.
本发明公开了一种钢渣基固化剂及其在含镍污染土壤固化中的应用。钢渣基固化剂包括以下组分：钢渣粉、矿渣粉、石膏、水泥熟料、激发剂、钙基膨润土、乙基黄原酸盐等组分，该钢渣基固化剂用于含镍污染土壤固化，其通过物理吸附‑化学吸附‑化学络合‑物理包裹的方式，能够从多维度对镍起到固化稳定化的作用，实现重金属镍的原位空间限阈，极大地降低了镍的迁移率，增强了镍固化的稳定性，且钢渣基固化剂采用的原料主要为固废物，达到以废治废目的，具有极大的经济及环保效益。
