摘要
Sewage sludge ashes in comparison to sewage sludge are characterized by higher concentrations of heavy metals. The mobility of heavy metals in sewage sludge ashes determines their impact on the soil-water environment in the aspect of toxicology. This research statistically evaluates the influence of temperature and duration of SS incineration on the mobility of HM from SSA. For the incineration temperatures 600-980 degrees C and 2-20 min of incineration, the experiment domain was defined in accordance with the Box's two-factor experimental design. It was proved that it was not the time but the temperature of SS incineration that had the statistically relevant influence on the mobility of nickel and copper.
