| description | The overall objective of this study was to develop and innovate sludge
treatment technology especially related to sewage sludge combustion. And to
investigate the thermal destruction of sewage sludge.
Sewage sludge characteristics were studied. Sewage s1udge is composed of
organic containing macro-nutrients such as nitrogen (N) and phosphor (P) and a
number of trace of heavy metals as e.g. zinc (Zn). However, sewage sludge also
contains components that are considered to be harmful to the environment.
Moisture content was found to be 70%, specific gravity was equal to 1.107, and
finally ash content was equal to 50%.
The temperature effect at the different gas emissions during sewage sludge
incineration using electrical muffle furnace was studied. It was found that
increasing the temperature would increase both sulphur and nitrogen oxides (NO,
N02),whereas it would decrease carbon oxides (CO. C02). The optimum temperature for sewage sludge incineration with minimum air pollution was found
to be 900 dc.
A study of the effect of limestone addition at the different gas emissions
during sewage sludge incineration was performed. It was found that adding
limestone during sewage sludge incineration win slightly increase nitrogen oxides
by 5-10% and carbon oxides by 0.02-11% while it effectively decrease sulphur
dioxide emissions by 65% at 900°C. The optimum reduction in sulphur dioxide
emissions can be achieved by using 2.0 CaiS mole ratio. |
