چکیده مقاله
Incineration followed by stabilization/solidification is identified as the demonstrated available treatment technology in the USA, according to Resource Conservation and Recovery Act In the present study S/S technology was applied on petrochemical incinerator bottom ash PI BA using Portland cement II 45 and two types of pozzolanic materials: silica fume and Nano SiO2 The leaching behavior of the cement based products was studied using standard environmental tests, TCLP and NEN 7375 effectiveness of treatmrnt was evaluated in terms of reducing the heavy metal leachability to the levels below the European and USEPA landfilling criteria An optimum composition for the PI BA stabilization was formulated as 45%Bottom ash 10% silica fume to achieve the environmental and economic criteria The results show that the stabilization process can be considered as an appropriate and cost effective alternative to hazardous waste landfill Furthermore, solidified products have a potential to be reused as construction materials in different applications
