摘要
通过对上海浦东新区垃圾焚烧发电厂炉渣的性质分析,研究了其物理组成和化学组成、浸出毒性、溶解盐含量及其形貌特征和矿物组成.结果发现,炉渣由熔渣、陶瓷/砖块碎片、石头、玻璃、铁和有色金属及极少量可燃物组成;以砾状颗粒为主(>2mm颗粒占60%以上);溶解盐含量≤1%;浸出毒性小;主晶相为SiO2、CaAl2Si2O8、Al2SiO5、CaCO3、CaO和ZnMn2O4.炉渣适合于资源化利用.
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 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 wastes; its minerals were mainly SiO2, CaAl2Si2O8, Al2SiO5, CaCO3, CaO and ZnMn2O4. The bottom ash was suitable for beneficial use.
