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

[0028] S1: Put 80 parts of waste straw into a pulverizer and pulverize it to a size of 2mm×2mm, then add 10 parts of cellulase to it, and react at a temperature of 50°C for 8h;

[0029] S2: Add 25 parts of linalool and 15 parts of dimethyl sulfide to the reactant in step S1, and stir at a rate of 450 r / min for 30 min at room temperature to obtain a mixed solution A;

[0030] S3: Add 12 parts of selenium dioxide, 20 parts of fine silicic acid, 9 parts of zinc ferrite and 18 parts of ferric ammonium citrate into the mixed solution A described in step S2, and react at a temperature of 80° C. for 16 minutes;

[0031] S4: Add 6 parts of acetylferrocene and 25 parts of glycerol phosphate to step S3, pressurize and react at a temperature of 80°C for 20 minutes; then press, dry and shape to obtain the water purification using waste straw Material.

Embodiment 3

[0038] S1: Put 60 parts of waste straw into a grinder and pulverize it to a size of 2mm×2mm, then add 6 parts of cellulase to it, and react at a temperature of 30°C for 6h;

[0039] S2: Add 20 parts of linalool and 12 parts of dimethyl sulfide to the reactant in step S1, and stir at a rate of 400 r / min for 25 minutes at room temperature to obtain a mixed solution A;

[0040] S3: Add 8 parts of selenium dioxide, 15 parts of fine silicic acid, 5 parts of zinc ferrite and 14 parts of ferric ammonium citrate into the mixed solution A described in step S2, and react at a temperature of 70° C. for 12 minutes;

[0041] S4: Add 2 parts of acetyl ferrocene and 18 parts of glycerol phosphate to step S3, pressurize and react at a temperature of 60°C for 15 minutes; then press, dry, and shape to obtain the water purification using waste straw Material.

Abstract

The invention discloses a water purifying material prepared from waste straw.The water purifying material is prepared from, by weight, 50-80 parts of waste straw, 5-10 parts of cellulose, 6-12 parts of selenium dioxide, 10-20 parts of superfine silicic acid, 3-9 parts of zinc ferrite, 10-15 parts of dimethyl sulfide, 13-18 parts of ammonium ferric citrate, 1-6 parts of acetylferrocene, 15-25 parts of glycerophosphate and 18-25 parts of linalool.By using the purifying material, metal impurities in water can be effectively degraded and removed, and an effective way is provided for recycling waste straw.

Description

technical field [0001] The invention belongs to the field of water treatment materials, and in particular relates to a water purification material utilizing waste straw and a preparation method thereof. Background technique [0002] my country is a large agricultural country, so there are a lot of crop straws produced every year, but the utilization rate of straws is seriously insufficient. At present, the common practice for straw is still simple and rude in-situ burning. The incineration of straw not only causes serious environmental pollution and fire hazards, but also a large waste of resources. As the country advocates five-in-one, sustainable development of circular economy and ecological economy, how to make better use of straw resources and turn waste into treasure has become a research hotspot. At present, most of the research is on the use of biomass degradation for power generation, but there are few reports on the field of water treatment. Contents of the inv...
