Embodiment 1

[0054] A photocatalytic nanofiber membrane, wherein the raw materials of the photocatalytic nanofiber membrane include 7 parts by weight of polyazineamide, 75 parts of dichloromethane, 0.4 part of chitosan, 0.2 part of methyltrichlorosilane, 12 parts by weight. 0.3 part of sodium alkyl sulfate and 0.05 part of trichloroacetic acid.

[0055] A kind of preparation method of photocatalytic nanofiber film, such as figure 1 shown, including the following steps:

[0056] S1. Introduce parts by mass of polyazineamide into dichloromethane, stir at room temperature until completely dissolved, and keep at 8°C for 12 hours to mature the polyazineamide so that its polymer chains are fully expanded in the solution to form a spinnable Good spinning solution;

[0057] S2, adding chitosan, methyltrichlorosilane, sodium lauryl sulfate and trichloroacetic acid to the spinning solution, then stirring for 5 minutes;

[0058] S3. Put the high-voltage electrospinning equipment in a closed system...

Embodiment 2

[0075] On the basis of Example 1, such as Figure 12 As shown, the inner end surface of the fixed support frame 21 is fixedly connected with the second catalytic lamp 26 for lighting evenly and equidistantly between the photocatalytic nanofiber membrane 24 and the nanocatalytic plate 25 .

[0076] When the present embodiment is in use, when the sewage is catalyzed, since the second catalytic lamp 26 is arranged between the photocatalytic nanofiber film 24 and the nanocatalytic plate 25, the second catalytic lamp 26 can maximize the The degree of illumination on the photocatalytic nanofiber membrane 24 improves the efficiency of subsequent catalysis.

Abstract

The invention relates to the technical field of sewage treatment equipment, in particular to a photocatalytic nanofiber membrane and oily sewage treatment equipment used therefor. The raw materials of the photocatalytic nanofiber membrane include: the raw materials of the photocatalytic nanofiber membrane include: 5-8 parts of polyazineamide, 60-80 parts of dichloromethane, 0.3-0.8 parts of chitosan, 0.1-0.3 parts of methyltrichlorosilane, 0.2-0.5 parts of sodium lauryl sulfate and 0.04-0.04 parts of trichloroacetic acid 0.09 part; the present invention imports polyazineamide into dichloromethane, stirs until completely dissolving into spinning solution, then adds chitosan, methyltrichlorosilane, sodium lauryl sulfate and three Chloroacetic acid is mixed and placed in high-voltage electrospinning equipment, and under the action of an electric field, it is split into fibers with a diameter of nanometers and attached to the receiving screen, and forms a dense nano-film structure, which greatly improves the performance of the fiber. The adsorption and treatment capacity of impurities in polluted water. At the same time, methyl trichlorosilane can endow the fiber membrane with low surface energy, so that the fiber membrane has excellent super-hydrophobic properties, large contact angle, and high oil removal rate when used for oily sewage treatment. .
