摘　　要：总结了含酚废水的来源及特征污染物,分别介绍了产甲烷细菌聚生体、硫酸盐还原细菌、反硝化细菌对酚类污染物的降解途径和机理,并进一步探讨了的温度、HRT、进水碳氮磷比、回流比、抗负荷冲击能力、以及酚类化合物的种类、含量和毒性等因素对升流式厌氧污泥床反应器(UASB)处理含酚废水的影响。通过投加共代谢基质、载体和生物固定化强化微生物的性能可以提高反应器的去除效率,今后可以进一步研究微生物强化、菌种筛选、反应器结构优化等方面,提高UASB处理含酚废水的运行稳定性、抗冲击负荷能力以及除酚效率。Phenolic wastewater sources and characteristics were summarized in this paper, the pathway and mechanisms of phenolic wastewater treatment by methanogentic consortium, sulfate reducing bacteria and denitrification bacteria, and the effects of operating temperature, HRT, carbon and nitrogen and phosphorus into water ratio, reflux ratio and resistance to impact load capacity, as well as the kinds and concentrations of phenolic compounds and toxic factors on wastewater containing phenol treatment by UASB processing were further discussed. By adding the common metabolizing material, the performance of the carrier and biological immobilized microorganisms could improve the removal efficiency of the reactor, microbial enhanced treatment could be studied in the future, bacteria screening, reactor structure optimization, etc., further improved the running stability of the UASB in wastewater containing phenol treatment, resistance to impact load capacity and phenol removal efficiency.
