NOVELTY - Performing aerobic composting of sludge, involves mixing base culture medium and sludge percolate, adding mixed liquid into triangular flask, inoculating e.g. Pseudomonas aeruginosa into flask, culturing bacteria, centrifuging obtained liquid A, inoculating precipitate into decayed sludge, culturing bacteria to obtain composition A, inoculating precipitate into sludge, culturing bacteria to obtain composition B, inoculating composition A into mixture, composting mixture, covering layer of composition B on surface of the compost and composting mixture.    USE - The method is useful for performing aerobic composting of sludge.    ADVANTAGE - The method is rapid, reduces loss of nitrogen elements in sludge, reduces composting period to 10-15 days, reduces ammonia gas in the compost by 30-50%, reduces environmental pollution and enhances fertilizer efficiency.    DETAILED DESCRIPTION - Method of performing aerobic composting of sludge, involves (a) mixing base culture medium and sludge percolate in volume ratio of 1-3:1, adding mixed liquid (500 ml) into triangular flask (1000 ml), inoculating Pseudomonas aeruginosa, Bacillus subtilis, B.licheniformis, B.coagulans, Lactobacillus plantarum, B.pumilus and Nocardia into triangular flask at 28-32 degrees C, where the inoculating amount of the bacteria is 10-20%, and culturing the bacteria for 24-28 hours to obtain liquid A, (b) centrifuging liquid A for 1-3 minutes at 7000-9000 revolutions/minute (rpm), inoculating obtained precipitate into decayed sludge using high-temperature compost based on inoculating amount of 5-10%, blending the mixture, adding the mixture to culture box for every 0.5-1 hour, ventilating the box with ventilation rate of 0.5-2 m3/minute.m3, maintaining the temperature of the mixture at 30-35 degrees C and culturing the bacteria for 3-5 days to obtain composition A, (c) mixing the base culture medium and sludge percolate in volume ratio of 1-3:1, adding mixed liquid (500 ml) into triangular flask (1000 ml), inoculating Paracoccus denitrificans, Aspergillus flavus, Phanerochaete chrysosporium, and Azotobacter chroococcum (10-30%) into flask at 48-52 degrees C, and culturing the microorganisms for 24-28 hours to obtain liquid B, (d) centrifuging the liquid B for 1-3 minutes at 7000-9000 rpm, inoculating obtained precipitate to the decayed sludge using high-temperature compost based on inoculating amount of 5-10%, blending the mixture, adding the mixture into the culture box for every 0.5-1 hour, ventilating the box with ventilation rate of 0.5-2 m3/minute.m3, maintaining the temperature of the mixture at 45-55 degrees C, and culturing the microorganism for 3-5 days to obtain composition B, (e) obtaining dewatered sludge with water content of 70-75% and organic substance content of 35-80%, adding regulating agent to the mixture, where the weight ratio of sludge to regulating agent is 1:1-3, and obtaining mixture (M1) with carbon-nitrogen ratio of 25-35 and water content of 55-65%, and (f) inoculating composition A (5-10%) into the obtained mixture (M1), composting the mixture, where the height of the compost is 0.8-1.5 m, when temperature reaches 45-55 degrees C, covering a layer of composition B with thickness of 0.05-15 m on the surface of the compost, composting the mixture continuously, after the temperature of the compost reaches environmental temperature, and completing the aerobic composting of sludge. The regulating agent is mixture of pumice, corn straw and wood chip.
