Abstract
The aspects of complex technology of sewage purification and utilization of purification sludge were investigated in the article. The authors substantiated the possibility of purifying sewage from heavy-metal ions by means of zeolite and utilizing sewage sludge in bricks production. The adsorption capacity of the zeolite from Sokyrnytsia deposit was studied for cupric and manganese ions in relation to its fractional composition. The comparative effectiveness studies of heavy metals adsorption by natural zeolite and anthracite were carried out. The optimal sorption parameters of these ions were selected based on the investigation results of their adsorption dynamics in the Cu2+ and Mn2+ solutions. The prospects of sewage sludge utilization by means of its thermal pyrolysis at the temperatures of 600–700°С were studied. The modifying additive was obtained, which can be added to the ceramic mixture and increase the porosity, reduce the density and decrease the thermal conductivity of course solid bricks.
