Choice of regime parameters of the process of heat treatment of waste- water sediments

  • V. V. Voznesenskii


A review of the main features that determine the choice of techniques of high-temperature treatment of waste-water sediments formed, for example, in refractory enterprises and often combined with sewage water is presented. The physicochemical compositions of the dried sediments are analyzed. The special features of the chemical composition of ash of mechanically dehydrated sediment fired in furnaces with a fluidized bed are presented, and the concentration of harmful substances in the worked-out heating agent is analyzed. It is shown that the parameters of high-temperature treatment of waste-water sediments are chosen with allowance for the composition of the precipitates arriving for treatment.
