摘要
固体废物水泥资源化利用必将是我国消纳大部分工业固废的有效途径之一,然而很多工业固废中会含有大量的硫、氯、碱金属等元素,这些物质的超量存在会影响到水泥窑协同处置工艺和水泥成品质量。本文通过综述国内外文献,归纳了典型工业固废中硫、氯、碱金属元素的含量范围,并介绍了它们对水泥资源化利用技术的主要制约因素,进而提出相应的调控措施,为工业固体废物水泥资源化利用提供必要依据。
TYhe solid waste recycling as cement production material （WAC） is one of the most effective way for the consumption of the industrial solid waste. However, industrial solid waste contains high level of sulfur, chlorine and alkali mental, which will affect the cement rotary kiln co-processing and the quality of cement products. In this study, the content range of sulfur, chlorine and alkali mental in typical industrial solid waste is concluded, the restrictive factors of sulfur, chlorine and alkali mental in WAC are presented, and the relevant control measures are proposed, which provide the necessary basis for the WAC.
