The invention discloses a method for preparing sodium hypochlorite by using reverse osmosis concentrated water, which comprises the following steps: S1, the reverse osmosis concentrated water enters a softener for softening treatment and then enters a carbon adsorption device, the softened water subjected to carbon adsorption treatment enters a water storage tank, and the water storage tank pumps the softened water into an electrolytic bath for electrolysis to prepare sodium hypochlorite; s2, when the reverse osmosis concentrated water is electrolyzed in the electrolytic tank, an aeration device is used for carrying out bottom aeration treatment on the solution, aerated gas and gas generated by electrolysis enter a chlorine gas collecting system together, sodium hypochlorite generated by the chlorine gas collecting system and the electrolytic tank is guided into a sodium hypochlorite storage tank to be stored, and gas generated by the chlorine gas collecting system is discharged. The reverse osmosis concentrated water is used as an electrolysis raw material, so that the problem of water plant concentrated water treatment is effectively solved, and sodium hypochlorite can be produced as a disinfectant for each process of a water plant for later use.
