Embodiment 1
[0018] S1: Put 50 parts of waste straw into a pulverizer and pulverize it to a size of 2mm×2mm, then add 5 parts of cellulase to it, and react at a temperature of 25°C for 5h;
[0019] S2: Add 18 parts of linalool and 10 parts of dimethyl sulfide to the reactant in step S1, and stir at a rate of 350 r / min for 20 min at room temperature to obtain a mixed solution A;
[0020] S3: Add 6 parts of selenium dioxide, 10 parts of fine silicic acid, 3 parts of zinc ferrite and 13 parts of ferric ammonium citrate into the mixed solution A described in step S2, and react at a temperature of 60° C. for 10 minutes;
[0021] S4: Add 1 part of acetylferrocene and 15 parts of glycerol phosphate to step S3, pressurize and react at a temperature of 50°C for 15 minutes; then press, dry, and shape to obtain the water purification using waste straw Material.
Embodiment 2
