The invention discloses a combined treatment method for addition waste water and cyclization waste water in a production process of lipoic acid. The method comprises the following steps: firstly, adding ferrous sulfate into the cyclization waste water to react to generate ferrous sulfide precipitates; performing nanofiltration on filtrate and washing liquid, extracting a concentrated solution by toluene, recovering the lipoic acid in the concentrated solution and mixing concentrated solution with the addition waste water; adding ammonium sulphate and sodium sulphate into the mixed addition waste water to react to generate ammonium alum; dividing the filtrate into the concentrated solution and penetrated liquid through nanofiltration of the filtrate, extracting the concentrated solution with dichloroethane and the toluene, and respectively recovering 8-chlorine-6-carbonyl ethyl octanoate and monoethyl adipate; after mixing the extracted aqueous phase with the penetrated liquids obtained by nanofiltration for two times, performing reverse osmosis desalination on the mixed liquid, and biochemical treatment, and discharging after standards are met. Through the use of the method disclosed by the invention, the comprehensive treatment and the resource utilization of the two strands of the waste water are performed, so that all the aluminium, sulphur, organic intermediates and lipoic acid in the waste water can be fully recovered, and at the same time, byproducts ammonium alum and ferrous sulfide products are obtained.
