The invention relates to a method for producing environment-friendly chloride snow melting agents from chloride-calcium type bittern. The method specifically comprises the step of subjecting chloride-calcium type mine bittern to procedures such as multiple evaporation, separation, sprinkling, granulating and drying to directly produce pure sodium-chloride type, pure chloride-calcium type, sodium-calcium complex type, calcium-sodium complex type and liquid snow melting agents. According to the method, a variety of chloride snow melting agents can be simultaneously produced by adopting one production process, so that the investment is reduced, the production cost is reduced, and the requirements on snow melting at different environments can be simultaneously met; meanwhile, the produced environment-friendly chloride snow melting agents are added with a corrosion inhibitor, so that the chloride snow melting agents play a role in protecting roads and bridges, are economical and environmentally friendly and are good in snow melting effect; the produced chloride-calcium type or sodium-calcium complex type snow melting agent products contain calcium chloride, thereby being capable of being used at lower atmospheric temperatures and accelerating a snow melting speed; and the produced chloride complex type snow melting agents are granulated by a fluidized bed after a solution is concentrated to a certain concentration through evaporation, calcium chloride and sodium chloride are mixed uniformly, and thus, the snow melting speed is uniform.
