Study on Artificial Inoculation of Municipal Solid Waste Thermophilic Aerobic Composting
Artificial inoculation of municipal solid waste by thermophilic aerobic composting was studied. The prime microorganism species of various periods were screened from thermophilic aerobic composting in constant cultivator, in which temperature is similar to the centre of thermophilic aerobic composting. The screened microbiology, cultivated individually, blended, were inoculated into large scales thermophilic aerobic composting. The degradation at different temperature and quantity of microbiology was assessed. Results indicated that it is feasible to intimate temperature of thermophilic aerobic composting by constant cultivator. The inoculation of first fermentation has no remarkable effect because of the quantity, but inoculation of the mold increases temperature of composting and enhances degradation in second fermentation. Finally the article indicated adding microorganisms may improve quality of composting and show clearly the direction for microorganisms screening.
