The invention provides a barium residue detoxifying method which comprises the step of adding barium residue in the cement production process, wherein the barium residue is 0.2-0.8% of the cement raw material by mass percent. According to the barium residue detoxifying method provided by the invention, the aim of recycling the waste barium residues generated in the industrial production of barium salt is achieved; what is more, the barium residues are thoroughly detoxified to solve the pollution to the environment, particularly the pollution to the water quality; through the method, barium-containing cement is obtained; compared with the traditional Portland cement, due to the introduction of barium, the fracture resistance and the compressive strength of the cement are remarkably improved (both the early and later strengths of the calcium barium sulphoaluminate mineral are relatively high, and the Ba<2+> enters in the crystal lattice of C2S to enable the crystal to warp so as to improve the hydration activity of C2S), and strong absorption function is brought to the gamma-ray so as to bring a certain radiation protection performance.
