The invention discloses a preparation method of modified activated carbon for removing organic malodorous gas and the modified activated carbon, belongs to the technical field of adsorption of the organic malodorous gas, and solves the technical problem of low adsorption rate of the organic malodorous gas in the prior art. The preparation method of the modified activated carbon for removing the organic malodorous gas comprises the following steps: carrying out primary carbonization treatment on a biomass raw material to obtain carbon powder; kneading carbon powder, strong alkali carbonate and an adhesive, and performing extrusion molding to obtain a green body; carrying out secondary carbonization treatment and activation treatment on the green body to obtain activated carbon; the preparation method comprises the following steps: soaking activated carbon in an oxygen-containing weak acid solution, and washing to be neutral after soaking to obtain a precursor; the precursor is soaked in an organic weak base so
