The invention belongs to the field of utilization of bromine-containing brine resources such as salt lakes, seawater, underground brines and industrial waste water, etc., which specifically provides a method for preparing hydrobromic acid and sodium bromide in a short process from bromine-containing brines. The process flow mainly includes the oxidation of bromine-containing brine, absorption of alkaline solution, preparation of hydrobromic acid by distillation, and preparation of sodium bromide by crystallization. This technology provides a new process scheme for preparing hydrobromic acid and sodium bromide by extracting bromine from brine. Compared with the traditional process, the process is greatly shortened and simple, easy to industrialize. Thus, the application prospect of this process is broad.
