METHOD FOR BIOLOGICAL TREATMENT OF ANIMAL WASTES Russian patent published in 2013 - IPC C05F3/00 C12N1/20 C12R1/85 

FIELD: chemistry.

SUBSTANCE: animal wastes are treated directly in animal farm facilities. A suspension of biomass of the Bacillus cereus 10.09.63 DEP strain deposited in the collection of the Russian State Centre for Quality and Standardisation of Veterinary Drugs and Feed is sprayed with number of healthy spore-forming bacteria Bacillus cereus of at least 2*10⁶ CFU/cm³, diluted with water in weight ratio of 1:60, respectively. The manure mass and manure effluent are collected and settled until separation into a liquid fraction and a solid fraction. After coagulation and clarification, the liquid fraction with pH not higher than 8.5 is used as biological fertiliser. The solid fraction is mixed with limed moss peat with pH not higher than 6.5 and coarse-grained sand with grain size of 1-3 mm with weight ratio of 1:(8-10):5. Soil with moisture content of not more than 65% is obtained.

EFFECT: invention simplifies recycling of animal wastes and enables to obtain biological fertiliser and soil.
