中文摘要：

含油废水具有毒性大、COD浓度高、可生化性差等特点，对水体、土壤以及动植物健康都有较大危害。采用水解酸化一曝气生物滤池（BAF）两段式工艺对陕西某油田经过滤后的含油废水进行处理，分别考察了水解酸化段和BAF的运行效果，确定了BAF工艺的最优工况，并对影响系统运行效果的主要因素进行了试验研究和理论分析。

英文摘要：

Oily wastewater has some characteristics such as high toxicity, high COD concentration and weak biodegradability, and it is harmful to the water environment, soil and the health of animals and plants. According to these characteristics, this paper employed the two stages hybrid process of hydrolysis acidification-BAF to treat the filtered oily wastewater. The effects of hydrolysis acidification stage and aerobic stage were studied respectively, the optimization of these two stages were determined, and the experimental research and theory analysis of the main factors affect ing system operation were also studied in depth.
