Abstract

Thermal disposal of sewage sludge is likely to cause serious nitrogen related environmental problem, since it contains considerable amount of nitrogen. Considering that iron oxide (Fe2O3) is widely applied chemical condition for sewage sludge treatment, this study was focus on investigating the role of Fe2O3 in N-containing gaseous products distribution during sewage sludge thermal decomposition in a tube/fixed-bed furnace at 900oC with or without oxygen, respectively. According to the result, conditioner Fe2O3 had little influence on N-containing component transformation when using raw sludge sample, while NO rose roughly with the increasing amount of Fe2O3 as de-mineralized sludge was used. Oxygen content promoted the formation of nitrogen oxidative products while inhibited the reductive ones. In practical application, adjusting oxygen content can make N-containing components to convert into reductive products, which reduced the NOx emission ultimately.
