【摘要】 <正> 随着城市污水处理量的加大及对水处理程度的深化,污泥作为污水处理的二次污染物,其产量也明显增加,如处理不当或不及时,会带来严重的二次污染,如恶臭、寄生虫卵、致病菌及对水资源和土地资源的污染。污泥处理技术已经成为当今最复杂的环境问题。污泥传统的处理方法有填埋、焚烧、填海,这些传统的方法都无法回收利用污泥中高有机质,而且其弊端在于随着污泥含量的增加明显暴露出来。近年来发展起来的污泥液化制油技术较好的实现了污泥资源化利用,使污泥处理技术走上了一条商业、环保的路线。在此实验中主要通过低温热解方法从污泥中获更多还原

【Abstract】 The oil composition produced by low temperature pyrolysis from sewage sludgewas analyzed by gas chromatography-mass spectrometry (GC/MS). The oil had aliphatic hydrocarbon and cyclic hydrocarbon, aromatic compounds, ranging from benzene derivatives to polycyclic aromatic hydrocarbons(PAHs),nitrogenated compounds. An important constituent of the pyrolysis oil from an environmental view is the PAHs which will give rise to a toxic oil. The proportion of PAHs is the highest and the bicyclic compounds such as naphthalene are present in a higher proportion than other PAHs.更多还原
