FIELD: chemistry.SUBSTANCE: invention can be applied in technology of artificial soil production, which is applied in road-transport construction, as manure for roadside landscaping, forestation, revegetation of polygons of solid household wastes and polygons of industrial wastes, for biological revegetation of disturbed lands. To realise the method changing of initial sewage sediment humidity is carried out. Sampling of suspension of sewage water sediment from sludge accumulator is carried out. Suspension of sampled sediment is pumped via pipeline with simultaneous determination of content of dry substance in it in unit of sediment preparation, where dilution of suspension with its further disinfection, sedimentation of ions of heavy metals and neutralisation of unpleasant smells are carried out.EFFECT: method ensures possibility of utilisation of considerable volume of public utility sewage sediment in its transportation via technological line.4 cl |
