FIELD: textiles, paper.SUBSTANCE: group of inventions relates to agriculture. The methods of biotechnological processing solid wastes of pulp and paper industry for obtaining biohumus comprise: a) the step of processing with fungi, which consists in the fact that fingal inoculum of basidiomycetes of white rot is applied in the solid wastes of pulp and paper industry at the rate of 0.8-1.1 litres per 10 kg of wastes or the grain mycelium of white rot fungi based on 300-350 g per 6-8 kg of wastes and the solid state cultivation is carried out during 45-65 days at a temperature of 18-28°C or within 15 days at a temperature of 10-15°C, and during the next 40-45 days - at a temperature of 18-28°C; b) the step of vermi-processing consisting in that the substrate obtained in step a) is moistened to 65-80%, then per 10 kg or per 6-8 kg of the said substrate 1300-2500 zooids or 200 pcs. adult red Californian earthworms Eisenia andrei are applied, then within 42-47 days the specified humidity is kept, at that the substrate is maintained at a temperature of 12-34°C; c) the stage of biohumus preparation consisting in the fact that the separation of worms from moist biohumus obtained in step b) is carried out, then the biohumus is dried to a moisture content of 50-65%.EFFECT: inventions enable to simplify the process of preparation of biohumus from solid wastes of pulp and paper industry, as well as to intensify the disposal of these wastes.10 cl, 4 tbl, 3 ex |
