Method for removing organic matters from ardealite

The invention discloses a method for removing organic matters from ardealite, which is characterized by comprising the following steps: taking ardealite, adding water, uniformly stirring and mixing, standing to layer solid and liquid, and removing black oily matters floating on the surface of water; adding quick lime and hydrogen peroxide into the phosphogypsum solid-liquid mixture, and stirring to react for 3-4 hours; carrying out suction filtration on the reacted solid-liquid mixture, and washing the solid with water until the pH value of the reacted solid-liquid mixture is 7-8; and carrying out suction filtration to obtain a solid matter which is the phosphogypsum without the organic matters. According to the method, organic matters in the phosphogypsum are removed, one part of the added quick lime and hydrogen peroxide react to generate oxygen to float the organic matters, and the other part of the added quick lime oxidizes organic compounds to be in an inorganic state; after the ardealite is treated by t
