The invention provides a recovery method of rectification residue liquid during tetrachloroethylene production. The method comprises the steps that during the tetrachloroethylene production, heavy ingredients of a quench tower kettle sequentially enter a light removing tower and a tetrachloroethylene rectification tower; tower kettle liquid enters a tetrachloroethylene removing tower again for secondary rectification; the tetrachloroethylene is further separated and recovered; tower kettle liquid after the tetrachloroethylene removal enters a pentachloroethane rectification tower; the tower kettle liquid enters a hexachloroethane rectification tower to obtain a hexachloroethane product. The problems of great useful ingredient discharge loss and great residue liquid processing quantity in a conventional heavy ingredient concentration recovery method can be effectively solved. The tetrachloroethylene in the heavy ingredients can be effectively recovered; the hexachloroethane product is sufficiently separated out, so that the loss is reduced; the cost is reduced; the benefits are increased.
