摘要
污水厂污泥低温热化学转化是可望达到能量平衡的污泥处理新技术。借助污泥与其转化产物的元素分析、污泥的热重分析和衍生油的GC/MS分析等手段,对该转化反应过程的元素转移、转化特征温度和反应机理进行了研究。认为过程的主要反应是脂肪族化合物的蒸发、蛋白质肽键断裂和基团转移反应,参与反应的主要成份是脂肪族化合物和蛋白质,其中前者参与反应的温度低于后者,而糖类化合物参与反应的温度最高。
The low temperature thermo chemical conversion process for sewage sludge ,through which the energy can be expected to be recovered,is a new developing technology. With the help of elemental composition analysis for sewage sludge and transfered products , thermal gravimetric analysis(TGA)for sewage sludge and GC/MS analysis for derived oil, it is discussed about the elements transfer,specified transfer temperature and reaction mechanism about the transfer reaction of the conversion process. The conclusion is that main conversion reactions are the evaporation of aliphatic compounds , the fission of protein peptide bond and the group transfer reaction,and that the main compositions involved in the conversion reaction are aliphatic compounds and protein,with higher reaction temperature for the former,lower for the latter and the highest for the saccharide compounds.
