FIELD: methods for temporary or constant disposal of sewage water sediment, in particular, for preservation of toxic bottom oil sludge and other kinds of sludge from storage pools in oil refining and chemical industry.
SUBSTANCE: method involves sequentially laying and compacting water-and-oil impermeable screen formed from drilling sludge and wastes which had been preliminarily dehydrated to residual moisture content of 5-30%; covering said sludge and wastes with water-and-oil impermeable screen, compacting, spilling layer of soil-plant ground thereon and planting. Dehydration of said sludge and wastes to residual moisture content is provided by evaporation in open air.
EFFECT: simplified disposal of toxic industrial wastes.
