METHOD OF PURIFYING INDUSTRIAL SEWAGES FROM HEAVY METALS

摘要

FIELD: chemistry.SUBSTANCE: invention can be applied at enterprises of ferrous and non-ferrous metallurgy, chemical industry for purification of industrial sewages, for example, for extraction of heavy metals from acid and subacid sewages with high content of heavy metals. To realise the method processing of sewages with liquid alkaline peat-humic preparation is performed with its ratio to solution of industrial sewages from 1:100 to 1:1000. Formed sediment of metal-organic complexes is separated from purified technogenic solutions and subjected to thermal enrichment of sediment by annealing at temperature 450-600°C.EFFECT: ensuring effective purification of industrial sewages from ecologically dangerous elements - heavy metals and extraction of useful components, ie realising complex industrial recycling of industrial sewages.2 dwg, 2 tbl
