Catalytic Combustion of Wastewater Sediments from Community Facilities
Chemistry for Sustainable Development
Boreskov Institute of Catalysis SB RAS
A process was studied concerning the combustion of municipal wastewater sediments from sludge fields of the Gorvodocanal Co. (Novosibirsk), in the fluidized bed of a catalyst. It was found that at the process temperature of 700 °C, the burnout level of the sediment amounted up to 98 %. In this case, the content of toxic substances (Hg, HCl, SO3, P2O5, СО, NOx meets the sanitary standards. It was demonstrated that the combustion of sediments is possible after its preliminary drying up to obtaining the moisture level equal to 54 %.
