METHOD FOR PREPARING ORGANIC ENVIRONMENTALLY FRIENDLY SNOW-MELTING AGENT FROM SALT SLURRY FROM TWO-ALKALI METHOD

Disclosed is a method for preparing an organic environmentally friendly snow-melting agent from salt slurry from the two-alkali method, belonging to the technical field of environment protection and solid waste recovery utilization. The method comprises the following steps: firstly carrying out a stirring reaction of an organic acid and a salt slurry from the two-alkali method at normal temperature, then filtering the reaction system, subjecting the resulting filtrate to pressure-reduced concentration and centrifugal spray drying to obtain a solid powder, and granulating the solid powder to obtain the organic environmentally friendly snow-melting agent. The method not only achieves cyclic utilization of the salt slurry solid waste, turns the waste into resources and greatly reduces the production cost of the organic environmentally friendly snow-melting agent, but also has significant synergistic increase with respect to the snow melting and ice thawing capability due to the presence of trace ions.
