一种油田稠油污水外排达标处理方法
摘要：
本发明涉及一种稠油污水处理的方法和工艺，稠油污水采用本发明的工艺流程：稠油污水—气浮预处理—IB-BACT生化处理—臭氧-生物活性碳处理—出水，其出水的CODCr不仅可达到国家污水综合排放标准(GB8978-1996)的一级排放标准限值(CODCr不超过100mg/L)，也可达到辽宁省地方污水排放标准(DB21/1627-2008)的标准限值(CODCr不超过50mg/L)。
摘要（英）：

The invention relates to a method and a process for treating thick oil sewage. The thick oil sewage is treated by adopting the process flows of air flotation pretreatment, biochemical treatment of immobile biology-bio-augmentation and compositive technology (IB-BACT), ozone treatment, bioactive carbon treatment and water discharge, the chemical oxygen demand (CODCr) of the discharged water not only can reach the level 1 discharge standard limit (the CODCr does not exceed 100mg/L) of national sewage comprehensive discharge standards (GB8978-1996), but also can reach the standard limit (the CODCr does not exceed 50mg/L) of local sewage discharge standards (DB21/1627-2008) of Liaoning province.
