With the rapid economic development and the increase in population in the whole world, the amount of municipal sewage (MS) is increasing and lead to a rapid increasing in amount of municipal sewage sludge (MSS). Combustion of municipal sewage sludge may be a viable solution for its disposal in some cases and so is its co-combustion with coal. Whereas significant information is available on NOx and N2O emissions characteristics of sludge and coal individually, not much has been reported on sludge/coal blends. In the present paper, investigations in NOx and N2O emission characteristics from circulation fluidized bed combustion of blends of municipal sewage sludge and coal were conducted in a 0.2MWth circulating fluidized bed test facility with cross section of 0.23×0.23m2 and height of 5.9m. Coal sample selected was a kind of lignite, while a kind of paper mill sludge was used as sludge sample. The influences of sludge/coal mixing rate, excess air ratio and second air ratio on NOx and N2O emission characteristics have been studied. Test results show that co-combustion of sewage sludge and coal is feasible. With the increasing in proportion of sludge of the sludge/coal blends, the temperatures in dense bed and freeboard decrease rapidly, and the emissions of NOx decrease while the emission of N2O increases obviously. With the increasing in excess air ratio, the emission concentrations of NOx and N2O increase. While with the increasing in secondary air ratio, the emission concentrations of NOx and N2O decrease.

In the remediation of heavy metal contaminated site, determining the remediation boundary of contaminated site and amount of contaminated soil are important link of the entire work. This paper uses surfer software to draw out a picture of Pb-contamination distribution in different soil layers, determines a remediation boundary, and provides a reliable basis and brings great convenience for later repair work.
