DEVELOPMENT OF EFFECTIVE SOLID WASTE MELTING PROCESS AND UTILIZATION OF MELTED SLUG

开发了有效的固体废物熔融工艺，并对熔融后的弹状物进行了利用。作为结果，得出了以下结论：1.固体废物有效熔融工艺的开发灰渣的熔融特性和重金属的浸出与其碱度(CaO/SiO_2)有关。通过磨损试验评价了段塞的物理强度，明确了段塞密度与其磨损量之间的密切关系。灰的组成影响熔融过程中的熔点、磨损量、重金属的浸出和燃料消耗，它们之间存在着权衡关系。根据这些结果，提出了有效的熔炼操作。熔融段塞在自密实混凝土和瓷砖材料中的应用建立了水层模型。该模型对自密实混凝土配合比设计是有效的。实践证明，熔融粘结剂在瓷砖材料中的应用是有效的，因为熔融粘结剂制成的瓷砖的焙烧温度比传统工艺低。

Development of the effective solid waste melting process and utilization of melted slug were done. As the results, the following conclusions were obtained.1. Development of the effective solid waste melting processThe melting characteristics of ash and leaching of heavy metals contained in slug were related with its basity (Cao/SiO_2). The physical strength of slug was evaluated by abrasion test, and a close relationship between the density of slug and its abrasion masses was made clear. A melting point, abrasion masses, leaching of heavy metals and fuel expense in melting process were effected by the composition of ash, and there were the trade-off relations in each other. With these results, the effective melting operation was suggested.2. Application of melted slug to self-compacting concrete and to materials of tilesThe water layr model was devised. This model was effective in designing the mix proportion of self-compacting concrete. It was proved that application of melted slug to materials of tile is effecteve, becouse the baking temperature of tiles made from slug were lower as compared a conventional process.
