The invention discloses a method for improving catalytic activity of a low-temperature denitration catalytic material in an industrial kiln by utilizing tourmaline and belongs to the field of environmental materials, environmental catalysis and environmental protection. According to the method disclosed by the invention, the waste acidolysis sludge produced in a titanium dioxide production processthrough a sulfuric acid process is taken as a raw material, a denitration catalytic material is prepared by adopting coprecipitation, the catalytic material is modified by doping tourmaline, and thecatalytic activity is improved. The preparative raw material of the catalytic material adopts the waste acidolysis sludge produced in the titanium dioxide production process through the sulfuric acidprocess, natural nonmetallic mineral tourmaline and the like, and waste recycling is realized; the prepared denitration catalytic material is low in cost, simple in process, short in process and applicable to industrial product
