The invention provides a fiber natural polymeric adsorbent, and belongs to the technical field of wastewater treatment. The fiber natural polymer uses bean dregs as a fiber source. Fresh bean dregs are successively treated by distilled water, ethanol solution and sodium bicarbonate solution for processing, so as to remove water-soluble substances and small molecular substances; and then the bean dregs are subjected to drying, crushing and sieving through a 100 mesh screen. Adsorption tests prove that the fiber natural polymer adsorbent has excellent adsorption performance on wastewater containing heavy metal lead ions and copper ions, a dye methylene blue, malachite green, basic fuchsin and organic pollutant naphthol. Therefore, the fiber natural polymeric adsorbent can be used for industrial treatment on wastewater containing heavy metal ion, dyes and organics. At the same time, the adsorbent mainly comprises components including cellulose, lignin and a small amount of glycoprotein, and ...
