Embodiment 1

[0016] Embodiment 1: a method for preparing a water-retaining and sand-fixing agent using furfural waste residue, the method is to add 3% sodium carboxymethyl cellulose and 1% acrylic resin into 30% water, heat up to 70 ° C and stir until completely dissolved, Then add 40% water and mix well. Then add 15% fermented furfural residue, 5% laterite, and 4% sand in sequence, pulverize to 2% wheat straw with a length of 2cm, and stir evenly to obtain a water-retaining and sand-fixing agent.

[0017] The preparation method of fermented furfural residue: the base material takes furfural waste residue as the basic raw material, adds 0.02% urea to adjust the carbon-nitrogen ratio, then inoculates 0.2% BM bacterial agent, and adds water to make the moisture content of the mixture 55-65%. After mixing, the piles are piled up to a height of 2m and a width of 2m. After the temperature rises to 65 ℃, the first turn over will start, and after that, it will be turned over every 5 days, and th...

Embodiment 2

[0018] Embodiment 2: a method of utilizing furfural waste residue to prepare a water-retaining and sand-fixing agent, the method is to add 1% polyvinyl alcohol, 2% acrylic resin, and 1% polyacrylamide to 28% water, heat up to 75°C and stir To dissolve completely, then add 40% water and stir well. Then add 12% fermented furfural residue, 8% clay, 5% attapulgite in sequence, pulverize to 3% corn stalk with a length of 3.5cm, and stir evenly to obtain a water-retaining and sand-fixing agent.

[0019] The preparation method of the fermented furfural residue: the base material is the furfural waste residue as the basic raw material, adding 0.06% urea to adjust the carbon-nitrogen ratio, then inoculating 0.5% BM bacterial agent, and adding water to make the moisture content of the mixture 55-60%. After mixing, make a pile, with a height of 1m and a width of 2.5m. After the temperature rises to 65 ℃, the first turn over will be started, and after that, the heap will be turned every ...

Embodiment 3

[0020] Embodiment 3: a method for preparing a water-retaining and sand-fixing agent by utilizing furfural waste residue, the method is to add 2% polyacrylamide, 1.5% starch, 2% polyvinyl alcohol to 34% water, heat up to 80 ° C and stir to Completely dissolve, then add 30% water and stir well. Then add 20% fermented furfural residue, 3% laterite, 2% clay, and 4% sand in sequence, crush to 1.5% straw with a length of 3cm, and stir evenly to obtain a water-retaining and sand-fixing agent.

[0021] The preparation method of the fermented furfural residue: the base material takes furfural waste residue as the basic raw material, adds 0.04% urea to adjust the carbon-nitrogen ratio, then inoculates 0.7% BM bacterial agent, and adds water to make the moisture content of the mixture 60-70%. After mixing, make a pile, with a height of 1.5m and a width of 2m. After the temperature rises to 65 ℃, the first turn over will be started, and after that, the heap will be turned every 6 days, a...

Abstract

The invention relates to a method for preparing a water retaining and sand fixing agent and particularly relates to a method for preparing a water retaining and sand fixing agent by using furfural residues. The method is characterized by comprising the following steps: adding super absorbent resin into water accounting for 20-45% of the total percentage by mass, heating up to 60-90 DEG C, stirring until the super absorbent resin is dissolved, adding the rest of water, then, sequentially adding the fermented furfural residues, a fixing agent and crushed plant straws, and uniformly stirring to obtain the tan pasty water retaining and sand fixing agent. In percentage by weight, 5-25% of fermented furfural residues, 5-20% of fixing agent, 0.5-5% of crushed plant straws, 1-10% of super absorbent resin and 50-85% of water are used. The method provided by the invention is unique, the furfural residues generated in a furfural production process are used as main components to prepare an environmental-friendly and degradable water retaining and sand fixing agent, and the water retaining and sand fixing agent not only can be used for preventing wind and fixing sand, but also can be used as a liquid film and a planting lawn.

Description

technical field [0001] The invention relates to a method for preparing a water-retaining and sand-fixing agent, in particular to a method for preparing a water-retaining and sand-fixing agent by using furfural waste residue. Background technique [0002] In the process of furfural production, a large amount of corncob waste and furfural waste residue will be produced; furfural production enterprises usually use furfural waste residue as fuel for boiler room combustion, and the exhaust gas emitted by burning furfural waste residue will pollute the environment. Furfural residue is a waste produced in the process of biomass hydrolysis, and its massive accumulation will pollute the atmosphere, soil and rivers. [0003] As a biomass waste, furfural residue contains a large amount of cellulose, hemicellulose and lignin, and has good reuse value. Therefore, rational resource utilization of furfural residues, eliminating its pollution to the environment, increasing the economic add...
