Zusammenfassung:The invention provides a recycling technology for wastes generated in the synthesis process of thioacetic acid. The recycling technology comprises the steps that in the synthesis process of the thioacetic acid, a thioacetic acid synthesis reaction solution is pretreated, the reaction solution is transferred into a filter device, the solid in the reaction solution is separated from the liquid, andthe wastes in the reaction solution are separated in advance; the solid obtained after separation is treated; the solid is washed, and after washing, separation is conducted; the solid obtained afterwashing is fed into a drier to be dried, and dried solid and a condensate liquid phase are separated out; the dried solid is added into a dissolving kettle, water is added into the kettle, stirring and heating are conducted, micro-boiling for reflux is conducted, so that the dried solid is fully dissolved; a potassium hydroxide solution is added into the solution for neutralization, wherein boiling is prevented in the neut
