The invention relates to a manufacture method of composite diatomite. The manufacture method is characterized by comprising the following steps: primarily mixing and stirring diatomite powder (200 meshes) and kaolinite powder (500 meshes) by utilizing a stirring device to obtain a mixture, calcining the mixture at the high temperature of 650 to 1000 DEG C in a rotating way, naturally cooling the mixture to 60 DEG C, adding calcium silicate (200 meshes) and calcium phosphate (200 meshes), roasting the mixture in a high-temperature rotary furnace at 150 to 180 DEG C, naturally cooling and drying the mixture, and carrying out air-type grading for the mixture to obtain a high-quality composite diatomite material. The manufacture method has the characteristics that the surface of micro-sized diatomite is decorated by utilizing micro-sized kaolinite, so that the specific surface area and porosity of the diatomite can be increased, the physical adsorption property of the diatomite can be improved, and high-quality diatomite series products can be produced by utilizing the technology.
