3、ntal Science, 2003,23(4) 395398 Abstract Characteristics of bottom ash from Shanghai Pudong Municipal Solid Waste Incineration Plant were studied, including physical and chemical composition, leaching toxicity, content of soluble salts, morphology and mineralogy. The results showed that, the bottom
4、ash was composed of slag, crushed ceramics and bricks, stones, glasses, ferrous and non-ferrous metals as well as very few combustibles; gravel-sized particles (2mm) were the main component over 60%; soluble salts content 1%; leaching toxicity was lower than the Identification standard for hazardous
5、 wastes; its minerals were mainly SiO 2 , CaAl 2 Si 2 O 8 , Al 2 SiO 5 , CaCO 3 , CaO and ZnMn 2 O 4 . The bottom ash was suitable for beneficial use.
