Claim 0:
1. A preparation method for a hyperthermophilic aerobic fermentation inoculant prepared by using sewage sludge, comprising:
fermenting hyperthermophilic aerobic bacteria to obtain a fermentation broth,
removing supernatant from the fermentation broth,
mixing the fermentation broth with protective agent to obtain a mixture,
drying the mixture,
pulverizing the dried mixture, and
sieving the pulverized mixture for packing;
wherein a culture medium for the fermentation is prepared by:
taking sewage sludge and adding water to the sewage sludge to regulate a solid content of the sewage sludge;
adding antifoaming agents of polyethers, yeast powder, ammonium chloride, sucrose, soluble starch, and potassium dihydrogen phosphate to the sewage sludge;
regulating pH of the sewage sludge;
adding composite carrier into the sewage sludge, and stirring the sewage sludge for uniformly mixing the composite carrier and the sewage sludge;
sterilizing the mixture of the composite carrier and the sewage sludge; and
cooling the sewage sludge to obtain the culture medium for the fermentation.
