Hyperthermophilic aerobic fermentation inoculant prepared by using municipal sewage sludge and its method

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.
