摘　　要： 针对油田废水中含有大量难降解性物质、可生化性差、水质变化大的特点,本实验设计时充分利用生物处理应用范围广,经济合理的特性,采用了“厌氧-好氧”相结合的工艺对辽河油田废水进行了初步实验研究。实验结果表明,在稳定运行后期,出水COD质量浓度为147～160mg/L,去除率高于60%;石油类质量浓度为1.00～1.16mg/L,去除率高于89%;挥发酚质量浓度为0.023～0.068mg/L,去除率高于80%;氨氮质量浓度为1.00～1.28mg/L,去除率高于75%。 Since the effluent from oilfield is characteric of having a lot of non-degradable substances, bad biodegradability and great variety of the water quality, the biological treatment, which has a wide applicable range and is economically reasonable, has fully been used. An elementary study on the effluent from Liaohe Oilfield has been carried on by a combined technology of the anaerobic and aerobic processes. The results show that in the later period of steady running, the mass concentration of outgoing water COD is 147 ～ 160 mg/L, its removal rate is over 60%; the mass concentration of petroleum is 1.00 mg/L to 1.16 mg/L, its removal rate is over 89%; the mass concentration of volatile phenol is 0.023 mg/L to 0.068 mg/L, its removal rate is over 80%; and the mass concentration of NH3 is 1.00 mg/L to 1.28 mg/L, its removal rate is over 75%.
