Burning Sewage Sludge From A Municipal Waste Water Treatment Plant – The Migreation Of Metals, Witold Zukowski, Jerzy Baron, Sylwia Chrupek, Malgorzata Pilawska

The migration of selected heavy metals has been analysed when sewage sludge from a municipal waste water treatment plant was burned in a bubbling fluidised bed. It has been shown that manganese, lead, arsenic, mercury and cadmium, as opposed to chromium, nickel and copper, leave the reactor mainly via the gas phase. To reduce the emissions of heavy metals to the atmosphere associated with the thermal utilization of sewage sludge requires more effective flue gases cleaning than is possible with filters.

A 100 kW atmospheric, bubbling fluidised bed reactor was used to study the combustion of wood waste, sewage sludge and a mixture of sewage sludge and meat-and-bone meal. Steady operation of the combustor was possible, even if the fuel was abruptly changed. With sewage sludge, the flue gas concentrations of SO2 and NOx were relatively high, as the sludge fuel contained much higher concentrations of combined S and N than e.g. wood waste. Co-combustion of sewage sludge and meat-and-bone meal presented no problems and the composition of the flue gases was similar to obtained the combustion of sewage sludge from …
