The present invention is a hydrogen peroxide solution (4 to be concentrated, a concentration method of an aqueous hydrogen peroxide solution to form two or hydrogen peroxide streams of different concentrations of the device containing the pre-evaporator (1), the distillation column (2) and vapor compressor (3) ) it was supplied continuously to the pre-evaporator, recovering the vapor (5) generated by evaporation from the pre-evaporator fed to the distillation column, and as a bottom product (6) first concentrated hydrogen peroxide stream (7) to be obtained in the pre-evaporator and the a bottom product (9) is recovered for steam (8) from the distillation column at the top of the distillation column and compressed through the vapor compressor and used to heat the pre-evaporator, and obtained in the distillation column which is generated in the distillation column 2 It relates to a method for the recovery of a concentrated hydrogen peroxide stream (10). In this way, by supplying a portion of the bottom product obtained in the pre-evaporator a distillation column in a liquid form, the hydrogen peroxide can be produced at the same time of two or rates the concentrated hydrogen peroxide solution freely selected of the different concentrations of 50 to 70% by weight .
