Abstrakt: | An effective procedure for stabilization/solidification of industrial wastewater treatment sludge has been developed and verified. The procedure consists of economically advantageous sludge solidification by fluidized bed combustion ash with an addition of highly porous carbon black as an adsorption additive, and subsequent creation of an asphalt coating on the surface of the solidified sludge by means of aqueous asphalt emulsion. The carbon black addition enables the reduction of binder dosage needed for solidification of the sludge and simultaneously reduces the leachability of organic compounds. The creation of an asphalt coating effectively prevents leaching of all pollutants observed. The method also reduces the infectiousness of the stabilized/solidified sludge. | ||||||||||
