Abstract
- Every year, as a result of the activities of the Baikal Pulp and Paper Mill, from 90 to 160 thousand tons of solid waste were generated. Lignin sludge is a sludge formed during the wastewater treatment of the plant. The disposal of waste from the production of the Baikal Pulp and Paper Mill was carried out in specially equipped dumps and storages. In model experiments using the method of solid-phase fermentation, the main patterns of ecological and biochemical processes occurring during the transformation of organic substrates (sludge-lignin, sawdust) were established; substrates were obtained for creating soil-ground. To develop the optimal composition of fertile mixtures from sludge-lignin after solid-phase fermentation, experiments were carried out to create artificial soils with different ratios of the resulting soils. The content of heavy metals in ready mixtures is much less than the concentrations specified in the regulations when using organic fertilizers [ABSTRACT FROM AUTHOR]
