摘 要采用高效液相色谱，对江苏省徐州市三个污水处理厂污泥中多环芳烃含量进行了检测。发现污泥中含有USEPA规定的16种多环芳烃化合物中的14种。各个污水厂污泥中的PAHs具有不同的分布特征。荆马河污泥中含量位于前三位的多环芳烃是苊烯、萘、蒽，各自占28.52%、19.23%、14.19%；开发区污泥中含量位于前三位的多环芳烃是荧蒽、苊烯、蒽，各自占31.84%、17.99%、11.81%；国祯污泥中含量位于前三位的多环芳烃是苊烯、蒽、萘，各自占25.36%、21.40%、17.49%。其中萘是两个苯环的PAHs，荧蒽、苊烯、蒽是三个苯环的PAHs，可见污泥中的多环芳烃均以低环化合物为主，主要是2和3个苯环的化合物。70717

Analysis on the existence feature of PAHs in municipal sludge of Xuzhou
Abstract The content of polycyclic aromatic hydrocarbons in sewage sludge from three sewage treatment plants in Xuzhou city of Jiangsu province was detected by high performance liquid chromatography. 14 kinds of polycyclic aromatic hydrocarbons among 16 USEPA PAHs were detected in the sludge. PAHs in each sewage plant has different distribution characteristics. Acenaphthylene, naphthalene, anthracene content in sludge from Jingma river sewage treatment plants are in the top three and are respectively accounted for 28.52%, 19.23%, 14.19%. The top three PAHs in the Kaifaqu sludge are fluoranthene, acenaphthylene and anthracene, their percentage is 31.84%, 17.99%, 11.81%, respectively. Acenaphthylene, anthracene and naphthalene are the top three PAHs in Guozhen sludge, respectively accounted for 25.36%, 21.40%, 17.49%. Among PAHs, which is rich in sludge, naphthalene contains two benzene rings; fluoranthene, acenaphthylene and anthracene contain three benzene rings respectively. It can be seen that low ring PAHs were dominated, mainly of compounds containing 2 and 3 benzene rings.
