TREATMENT OF EFFLUENTS SEDIMENTS Russian patent published in 2011 - IPC B09B3/00 C05F7/00 

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of effluents sediments with subsequent use as, particularly, organic additives introduced into soil for enrichment with nutritive and biologically active substances. Proposed method comprises turning the deposit into pasty state by mixing it with paste-forming agent, granulation and drying the granules. To this end, effluents deposits with average moisture content of 67-85% are used. As paste-forming agents used are biodegradable and/or biologically available substances in the amount of 35 to 85 percent of produced pasty mix weight that feature moisture content 30-35% lower than average moisture content of processed portion of effluents sediment. Volume of granules varies from 1.4 to 18 cm³. Granules produced are dried at no higher than 50°C to granule moisture content of 12-14%.

EFFECT: ecological compatibility of granules with accelerated mechanical degradation, higher reclamative effect.
