Embodiment 1
[0030] refer to figure 1 as shown, figure 1 Indicates the carrier structure of honeycomb straight inclined tube, in which 1 means the filler shaped like a honeycomb straight inclined tube, and 2 means the coating coated on the surface of the carrier.
[0031] The preparation method of the carrier is as follows:
[0032] 1) Press the PP filler into a solid filler of honeycomb straight inclined tube type by using a mold;
[0033] 2) dissolving polylactic acid in dichloromethane, dissolving, adding silicate at the same time, preparing polylactic acid-silicate solution;
[0034] 3) immersing the solid filler prepared in step 1) into the solution prepared in step 2) to coat the surface of the filler with polylactic acid and silicate;
[0035] 4) Ventilate and dry the solid filler coated in step 3), and completely volatilize the dichloromethane in the solution to obtain a composite biofilm carrier of polylactic acid-silicate coating coated PP filler
[0036] figure 2 Represent...
Embodiment 2
[0040] The packing of the support structure is corrugated:
[0041] The preparation method of the carrier is as follows:
[0042] 1) Mix ceramic particles and calcium alginate and use a mold to press into a solid filler of honeycomb straight inclined tube type;
[0043] 2) dissolving starch and calcium sulfate in dichloromethane to form a solution;
[0044] 3) immersing the solid filler prepared in step 1) into the solution prepared in step 2) to coat the surface of the filler with a coating;
[0045] 4) ventilating and drying the solid filler coated in step 3) to obtain a composite biofilm carrier.
[0046] The carrier prepared in Example 2 was subjected to a biofilm growth experiment, and it can also achieve biofilm fixation and film-hanging maturation, and has good decontamination ability.
Embodiment 3
[0048] The filler of the carrier structure is of fibrous type:
[0049] The preparation method of the carrier is as follows:
[0050] 1) Mix glass pellets and polyethylene terephthalate and use a mold to press into a honeycomb straight inclined tube-shaped solid filler;
[0051] 2) dissolving aliphatic polyester and diatomaceous earth in dichloromethane to form a solution;
[0052] 3) immersing the solid filler prepared in step 1) into the solution prepared in step 2) to coat the surface of the filler with a coating;
[0053] 4) ventilating and drying the solid filler coated in step 3) to obtain a composite biofilm carrier.
[0054] The carrier prepared in Example 3 was subjected to a biofilm growth experiment, and it can also achieve biofilm fixation and film-hanging maturation, and has good decontamination ability.
