Microwave Vitrification of Hazardous Sludge by Şırnak Asphaltite Slime, Shale and Sewage Sludge – Landfill Management by Vitrified Char Sand

Abstract

Mazıdağı Etibakır Cu ore leaching waste stockpiles, land soil and groundwater in the field should be controlled for seepages to avoid the acidic flow of solute containing the heavy metals of Pb, Cu and Zn. The heavy metal-associated liquor from Electrowinning Plant and Sulphuric acid Dissolution units threats the neighborhood in the town. Cu and Co are recovered by electrolysis and acidic solutions of Cu leaching are spent. According to this concern of waste management, a method commonly used, “vitrification of sludge,” among others such as special cementing or bituminous pasting may be used in the waste disposal and even ground stabilization. However, mixing that with glassy powder and further vitrification furnace heating yield a vitrified form of waste sludge, covered by glazed matter avoiding contact with water in the landfill. In this study, sodium silicate is used as a binder in the vitrification mixture with the sludge at 14% water under microwave radiation. The dissolved contents of Pb Zn and Fe in the yielded vitrified briquette are determined. Additionally, the strength of vitrified briquettes is investigated in terms of vitrification parameters of microwave radiation.
