The invention provides a method for recycling a waste fiber glass fabric for glass production. The method is characterized in that the waste fiber glass fabric is prepared into a composite porous material, and then the composite porous material serves as a glass recovery material to be recycled for glass production; or the composite porous material adsorbs metal ions and then serves as a glass coloring agent to be recycled for glass production, and the composite porous material is formed by adhering a porous carbon layer onto the surface of the waste fiber glass fabric. The method has the advantages that the preparation system of the composite porous material is simple and easy to operate, and the obtained composite porous material can be easily ground into particular powder, so that the composite porous material can more easily serve as the glass recovery material to be recycled. Meanwhile, the composite porous material can adsorb such toxic ions as chromium in waste water and serve as the coloring agent after adsorption, cyclic utilization of the waste fiber glass fabric and removal of the toxic ions in waste water are realized simultaneously, and very good environmental friendliness and economic benefits are achieved.
