Polychlorinated dibenzo-p-dioxins and dibenzofurans in fly ash and cinders collected from several municipal incinerators in Japan.
Determination of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in fly ash and cinders collected from nine municipal incinerators in Japan was made. The concentrations of PCDDs and PCDFs in this study were generally in the same range as those in Europe and North America. However, the rather different congener composition compared with those published already...
متن کاملVitrification of Bottom Ash from A VR MSW incinerators
During incineration of municipal solid waste (MSW), various environmentally harmful elements and heavy metals are liberated either into bottom ash, or carried away with the off-gases and subsequently trapped in f ly ash. If these minor but harmf itl elements are not properly isolated and immobilized, it can lead to secondary environmental pol/ution to the air, soil and water. The stricter envi...

15 صفحه اولInvestigation of basic properties of fly ash from urban waste incinerators in China.
Basic properties of fly ash samples from different urban waste combustion facilities in China were analyzed using as X-ray fluorescence (XRF), scanning electron microscopy (SEM), X-ray diffraction (XRD). The leaching toxicity procedure and some factors influencing heavy metals distribution in fly ash were further investigated. Experimental results indicate that the fly ash structures are comple...
متن کاملProcesses for Treatment of Heavy Metals in Ash from Municipal Solid Waste Incinerators
Modem municipal waste combustors (MWC's) process approximately 100 million tons of refuse each year in the United States, Europe and Japan, producing 30 million tons of ash. The incineration process has the effect of concentrating the toxic heavy metals normally present in municipal refuse. As a result, the ash may require treatment to reduce the quantity or the mobility of heavy metals within ...
