preparation example Construction

[0025] 1, the invention provides a kind of preparation method of functional furan resin, comprises the steps:

[0026] S1: Mix liquid furan resin and solid anthraquinone in a certain proportion and stir to form a uniform liquid;

[0027] S2: standing the homogeneous liquid obtained in step S1 at 10-90° C. for 0.1-24 hours to form a solid;

[0028] S3: keeping the solid obtained in step S2 at 100-150° C. for 0.5-10 hours to obtain a functional furan resin.

[0029] Wherein, in the step S1, anthraquinone has the following general chemical structure formula:

[0030]

[0031] Wherein, in the general chemical structure formula of anthraquinone, the substituent R includes but not limited to: hydrogen, sulfonic acid group, nitro group, halogen, alkyl group, alkoxyl group and hydroxyl group, and can be selected from one of the above substituent groups species, or a mixture of any two or more of the above substituents.

[0032] Wherein, in the step S1, it also includes uniformly...

Embodiment 1

[0059] S1: Mix 100g of liquid furan resin and 1g of anthraquinone and stir evenly to obtain a viscous liquid;

[0060] S2: standing the viscous liquid obtained in step S1 at 90° C. for 0.1 h to form a solid;

[0061] S3: Keep the solid obtained in step S2 at 100°C for 10 hours to obtain 81 g of functional furan resin, which contains anthraquinone 5.9×10 -5 mol\g.

Abstract

The invention discloses a functional furan resin and a preparation method thereof. The preparation method comprises the following steps: S1, mixing a liquid furan resin with solid anthraquinone according to a certain ratio, and performing stirring to form an uniform liquid; S2, allowing the liquid obtained from the S1 to stand at 10-90 DEG C for 0.1-24h to form a solid; and S3, performing continuous thermal insulation to the solid obtained in the S2 at 100-150 DEG C for 0.5-10h to obtain the functional furan resin. The provided functional furan resin can be taken as a redox mediator, can effectively increase the denitrification rate of microorganisms in a denitrification process, builds up the speed of degrading harmful substances in wastewater by microorganisms, and has bright application prospects in the water treatment field.

Description

technical field [0001] The invention relates to the fields of chemical engineering, biological engineering and environmental engineering, in particular to a functional furan resin for accelerating the denitrification rate of the microbial denitrification process and a preparation method thereof. Background technique [0002] Furan resin refers to the general term for high molecular polymers synthesized from furfuryl alcohol and furfural with furan ring structure as the main raw materials. The reaction solidifies to an insoluble and infusible solid. Common furan resins include furfuryl alcohol resins (resins synthesized with furfural alcohol, furfural, formaldehyde, and urea as the main raw materials, or resins synthesized with furfural, urea, and formaldehyde as the main raw materials and diluted with furfuryl alcohol as solvents, called furfuryl alcohol resins), Furfural resin (resin synthesized with furfural, urea and formaldehyde as main raw materials is called furfural ...
