发明名称 PROCESS OF PROCESSING OF HIGH-TOXIC INDUSTRIAL WASTE
摘要 processing of liquid and solid radioactive waste, phosphor-organic toxic agents and pesticides. SUBSTANCE: high-toxic industrial waste is mixed with mineral binder carrying cement containing calcium in the amount of 50-70 per cent by mass and waste of metallurgical process in the amount of 30-50 per cent. Slag of alumothermal production of ferrotitanium or chromate slime won in processing of chromate ore can be used in the capacity of waste of metallurgical process. Prepared pulp is used to fill double layer basalt-titanium slag-casting reactor-container, pulp is heated to 200 C with the use of SHF energy and isothermal curing of mixture at fixation temperature is conducted. Then obtained polycrystalline cement matrix is cooled in the course of 1.0- 2.0 h. EFFECT: possibility of long-term and sufficiently reliable immobilization of high-toxic industrial waste in polycrystalline cement matrix. 7 cl, 3 tbl _
