Abstract: Pretreatment of oil samples from pyrolysis of wastewater sewage sludge was carried out using combination route of extraction, enrichment and purification for determining PAHs.Quantitative and qualitative analysis of PAHs were then conducted by GC-MS.16 kinds of PAHs were detected out in sludge pyrolysis oil.The recovery ratio of PAHs is above 80% except for naphthalene on the basis of the constructed pretreatment method and GC-MS analysis condition.Finally, distribution of PAHs was also investigated using experimental tests in three sludge pyrolysis oil samples produced from various ending temperature and heating rate.The total content of the target PAHs in three oil samples is from 2.3 mg·kg-1 to 47.8 mg·kg-1.In addition, the ending temperature and heating rate have evident influences on PAHs concentrations in sludge pyrolysis oil.

Key words: wastewater sewage sludge, pyrolysis oil, polycyclic aromatic hydrocarbons, recovery ratio
