METHOD OF PROCESSING OF SOLID MUNICIPAL WASTES

摘要

FIELD: waste processing and disposal.;SUBSTANCE: proposed invention relates to recycling of stale solid municipal wastes (SMW) by thermal treatment for the purpose of reclamation of lands occupied for polygons. Proposed method comprises their delivery, sorting with oversize separation, extraction of metal fraction and thermal processing in molten bath. Besides, natural gas and biogas, extracted as a result of SMW decomposition in the landfill (dump) body, are blown into the melt together with air containing oxygen, at total heat of natural gas, biogas and SMW combustion from 7,000 to 8,100 kJ/kg to maintain temperature melt ranging from 1,300 to 1,500 °C.;EFFECT: technical result of the invention consists in improvement of environmental protection degree, expansion of technological capabilities by means of non-waste utilization cycle and possibility of processing of biogas formed during storage and as a result of its combustion – saving heat carrier flow.;1 cl, 1 dwg, 1 tbl
