Embodiment 1
[0019] The immobilized microbial rubber particle filler of the present invention includes rubber particles as a carrier, an embedding agent and a microbial enzyme preparation for providing microorganisms, and the rubber particles interact with the embedding agent and the microbial enzyme preparation to form Synthesize the polymer gel, embed and fix the microorganisms in the microbial enzyme preparation in the gel network to form the rubber particle filler of the immobilized microorganisms, the microbial enzyme preparation used in this embodiment is carbonized thallus, see figure 1 , its particle diameter is 0.5-1mm, and the diameter of the rubber particle used is 5-8 millimeter (referring to figure 2 ), the embedding agent used is polyvinyl alcohol, wherein the mass ratio of rubber particles, polyvinyl alcohol and carbonized bacteria is 3:30:0.02.
[0020] The preparation method of the immobilized microbial rubber particle filler of the present embodiment is as follows: (1) ...
Embodiment 2
[0025] The difference between this embodiment and embodiment 1 is that the mass ratio of rubber particles, polyvinyl alcohol and carbonized bacteria is 6.5:38:0.08, and the others are the same as in embodiment 1, and will not be repeated here.
Embodiment 3
[0027] The microbial enzyme preparation used in this embodiment is carbonized thallus, see figure 1 , its particle diameter is 0.5-1mm, and the diameter of the rubber particle used is 5-8 millimeter (referring to figure 2 ), the embedding agent used is polyvinyl alcohol and sodium alginate, wherein the mass ratio of rubber particles, embedding agent and carbonized bacteria is 4.5:35:0.05, and the mass ratio of polyvinyl alcohol and sodium alginate is 50:1.
[0028] The preparation method of the immobilized microbial rubber particle filler of the present embodiment is as follows: (1) Preparation of rubber particles: 80% old tire powder and 20% ethylene-vinyl acetate (EVA) and activated carbon are mixed and stirred, and compressed into diameter (2) The total mass of polyvinyl alcohol and sodium alginate is 350 kg, and polyvinyl alcohol and sodium alginate are formulated into a solution at a mass ratio of 50:1; (3) 0.5 kg of carbonized The dry powder of the thalline was added i...
