The invention relates to a method for recycling solid wastes in carbonate production, and the method belongs to the technical field of recycling of industrial wastes. The method comprises the following process steps: measuring the content of pyridine salts in the solid wastes, adding sodium hydroxide solution into the solid wastes, carrying out the reaction according to that the weight ratio of the pyridine salts to the sodium hydroxide is 1:1-3:1, then carrying out full distillation; adding solid sodium hydroxide into distillate according to the water content of the distillate, stratifying after full dehydration, then infiltrating the lower layer of concentrated liquid caustic soda into a reserve tank for treating the next batch of the solid wastes, directly injecting the upper layer of pyridine solution to a rectification tower for rectification; collecting fractions before 115 DEG C and dehydrating the fractions together with the next batch of reaction distillate, collecting the fractions after 115 DEG C and obtaining an industrial pyridine product. The method has reasonable design, simple process, strong operability, small working environmental toxicity and harm, high recoveryrate of pyridine and low cost, and the content of the recovered pyridine is more than 99 percent which achieves the industrial application standards.
