摘　　要：苯并(a)芘是一种致癌物、致畸原和诱变剂,是毒性最大的多环芳烃。本文利用微生物微电解质体系降解压裂返排液沉降底泥中的苯并(a)芘,通过对微生物的生长过程的观察与压裂返排液沉降底泥中苯并(a)芘含量的变化,优选出有效的菌群实验配比及微电解质环境。Benzo(a)pyrene is a carcinogen, teratogen and mutagenic agent. It is the most toxic polycyclic aro-matic hydrocarbon. In this paper, a microbial micro-electrolyte system was used to degradation of Benzo(a)pyrene in the sedimentation sediment of fracturing flowback fluid. By observing the growth process of microorganisms and the change of Benzo(a)pyrene content in the sedimentation sediment of fracturing flowback fluid, the effective microbial flora experiment ratio and micro-electro- lyte environment were optimized.
