The invention discloses a method for recycling halogenated short chain quaternary ammonium salt waste. The method comprises the following process steps: the halogenated short chain quaternary ammoniumsalt waste is dissolved in water and decomposed under the action of inorganic base, a tertiary amine organic layer is produced and separated from a water layer, and raw material tertiary amine is recovered from the tertiary amine organic layer through distillation and applied to production of halogenated short chain quaternary ammonium salt; the water layer is subjected to extraction through trichloromethane, an extracted organic layer and an extracted water layer are produced, trichloromethane is recovered from the extracted organic layer through distillation for recycling, halogenated shortchain quaternary ammonium salt after recovery of trichloromethane is recrystallized, and qualified halogenated short chain quaternary ammonium salt is obtained; distilling concentration, crystallization and centrifugation are performed on the extracted water layer, and an inorganic bromide byproduct is obtained for recycling. The efficient, economical and environment-friendly method for recyclinghalogenated short chain quaternary ammonium salt waste is provided, so that the environment-friendliness of production of halogenated short chain quaternary ammonium salt is improved, waste dischargeis reduced, and production cost is reduced.
