Calcium-containing preparation for compacting and decontaminating sludge sediments and method of processing sludge sediments using thereof

2015 
FIELD: chemistry. SUBSTANCE: calcium-containing preparation for compacting and decontaminating sludge sediments of treatment facilities is a mechanical powder mixture comprising up to 50 wt % of at least two active components selected from the compounds: TiO 2 , SiO 2 , CuSO 4 , Na 2 SO 4 , alkali, sodium humate, ammonium humate, aminoacetic acid, cuprum glycinates, manganese, calcium, the rest - CaO. The calcium-containing preparation is mixed with slusge sediment, liquid (water) and solid phases are separated by sedimentation method and then diversion of the liquid phase (water) is carried out. Calcium-containing preparation is used at a dose of 1-30 g/dm 3 . At least one active additive selected from the compounds: CuSO 4 , Na 2 SO 4 , Na 2 CO 3 , alkali, sodium humate, ammonium humate, aminoacetic acid, cuprum glycinates, manganese, calcium at a dose of 8 g/dm 3 , is additionally added to the sludge sediment, at least after one or at one of the mixing, separating and water diverting stages. EFFECT: invention enables to ensure highly efficient processing of the sludge sediments of treatment facilities, comprising activated sludge, raw sludge or a mixture thereof, while reducing the cost of the proposed preparation. 11 cl, 2 tbl, 11 ex
