Embodiment 1
[0045] A preparation method for embedding immobilized microbial spheres, the specific steps are as follows:
[0046] (1) Preparation of immobilized microbial particles:
[0047] Take 80 mesh halloysite nanotubes and join in the citric acid solution that concentration is 3wt% and stir evenly, obtain acid activated halloysite nanotube liquid after acid activation 3h, the weight of described halloysite nanotubes and citric acid The dosage ratio is 1:3.
[0048] The acid-activated halloysite nanotube solution was thermally activated at 500° C., and was taken out after 1.5 hours to obtain thermally activated halloysite nanotubes. The modified halloysite nanotubes are obtained by pulverizing the thermally activated halloysite nanotubes through 200 mesh.
[0049] Take 10 parts of modified halloysite nanotubes and 60 parts of brevibacillus D-1 at a concentration of 6×10 9 The cell / g seed bacterial liquid is mixed until the modified halloysite nanotube absorbs the seed bacterial liq...
Embodiment 2
[0058] A preparation method for embedding immobilized microbial spheres, the specific steps are as follows:
[0059] (1) Preparation of immobilized microbial particles:
[0060] Take 60 mesh halloysite nanotubes and join in the citric acid solution that concentration is 3wt% and stir evenly, obtain acid activated halloysite nanotube liquid after acid activation 2h, the weight of described halloysite nanotubes and citric acid The dosage ratio is 1:4.
[0061] The acid-activated halloysite nanotube solution was thermally activated at 400° C., and was taken out after 2 hours to obtain thermally activated halloysite nanotubes. The modified halloysite nanotubes are obtained by pulverizing the thermally activated halloysite nanotubes through 150 mesh.
[0062] Take 10 parts of modified halloysite nanotubes and 40 parts of brevibacillus D-1 at a concentration of 6×10 9 The cell / g seed bacterial liquid is mixed until the modified halloysite nanotube absorbs the seed bacterial liqui...
Embodiment 3
[0071] A preparation method for embedding immobilized microbial spheres, the specific steps are as follows:
[0072] (1) Preparation of immobilized microbial particles:
[0073] Take 60 mesh halloysite nanotubes and join them in a citric acid solution with a concentration of 3wt% and stir evenly to obtain acid-activated halloysite nanotube liquid after acid activation for 1h. The weight of the halloysite nanotubes and citric acid The dosage ratio is 1:2.
[0074] The above acid-activated halloysite nanotube solution was thermally activated at 400° C., and was taken out after 1 hour to obtain thermally activated halloysite nanotubes. The modified halloysite nanotubes are obtained by pulverizing the thermally activated halloysite nanotubes through 200 mesh.
[0075] Take 10 parts of modified halloysite nanotubes and 30 parts of brevibacillus D-1 at a concentration of 6×10 9 The cell / g seed bacterial liquid is mixed until the modified halloysite nanotube absorbs the seed bacte...
