摘　　要：摘 要 采油废水具有含盐度高、成分复杂、处理难度大等特点,采用传统的活性污泥法难以有效处理.文章采用实验室筛选出的嗜盐菌与序批式活性污泥法（SBR）工艺相结合处理高含盐的采油废水.结果表明：采用嗜盐菌结合SBR法对高盐度的采油废水进行处理,COD的去除率在32.2％～76.2％;SBR反应的最佳pH值为5.5,最佳反应时间为4～10 h.Oil exploitation wastewater possesses the characteristics of high salinity,complex composition and difficult management,etc,and it is hard to be treated efficientlyby traditional activated sludge method.This article use the screened halophilic bacteria from laboratory and sequencing batch reactor activated sludge process (SBR) to deal with high salinity oil exploitation wastewater.Results showed that the removal efficiency of COD was 32.2%-76.2%by the process combing with halophilic bacteria and SBR.The optimum pH value of SBR reaction was 5.5 and the best reaction time was 4-10 h.
