上海市建筑垃圾中转站垃圾理化特性研究

Study on physical and chemical characteristics of waste from construction waste transfer stations in Shanghai

针对上海老港末端处理的建筑垃圾残渣组分差异较大问题,本文对上海市九个区建筑垃圾中转站的建筑垃圾可燃组分和不可燃残渣的组分质量比例、含水率、热值、灰分、碳浓度和硫浓度进行了研究分析。结果表明,上海市各区建筑垃圾之间的组分差异较大,对建筑垃圾组分质量比例、含水率、热值和焚烧灰分等指标的影响大小分别为塑料、竹、布和纸,建筑垃圾残渣中总有机碳(Total Organic Carbon,TOC)的含量均在5%以下,硫元素含量为0.11%~0.54%,与生活垃圾的含硫量基本相似。

In view of the great difference in the composition of construction waste residue treated at the end of Shanghai Laogang,this paper analyzes the mass ratio,moisture content,calorific value,ash content,carbon concentration and sulfur concentration of combustible components and non-combustible residues of construction waste from construction waste transfer stations in nine districts of Shanghai.The results show that the components of construction waste in different districts of Shanghai are quite different.The influences on the mass ratio of components,moisture content,calorific value and incineration ash of construction waste are plastic,bamboo,cloth and paper respectively.The total organic carbon(TOC)content in construction waste residue is below 5%,and the sulfur content is 0.11%~0.54%,which is basically similar to the sulfur content of domestic waste.
