FIELD: chemistry.
SUBSTANCE: invention relates to ecology and can be used in recycling wastewater sludge formed at city aeration stations. The method involves mixing wastewater sludge with storage life of less than 3 years with turf in volume ratio of 0.5:0.5 or 0.6:0.4, respectively. The obtained mixture undergoes aerobic composting in the presence of a biological activator in amount of not less than 15% of the volume of the compost mixture. The biological activator used in the compost mass is inoculating compost based on poultry droppings and microbial strains Bacillus subtilis B-168, Bacillus mycoides B-691, Streptomyces sp. Ac-154, Mukor psychrophilus F-1441, Candida utilis Y-2441 in amount of 1·106-1·107 cells per millilitre per ton of poultry droppings.
EFFECT: shorter composting time.
