A/O~2法在炼油污水处理中的应用

为探索Ａ／Ｏ２（厌氧Ａｎａｅｒｏｂｉｃ／好氧Ｏｘｉｃ／好氧Ｏｘｉｃ）法在处理炼油污水中的应用，进行了Ａ／Ｏ２法中型试验，验证ＮＨ３－Ｎ容积负荷与去除率之间的关系，以及溶解氧、含油量对处理效果的影响等几项内容。Ａ／Ｏ２法应用于炼油污水的处理是可行的，对ＣＯＤ、ＮＨ３－Ｎ、油、酚、ＳＳ等有很好的处理效果。将Ａ／Ｏ２法应用于济南炼油厂，各构筑物运转正常，处理效果很好，完全达到国家排放标准。Ａ／Ｏ２用来处理炼油污水，工艺可行、技术先进、经济合理，不仅对ＣＯＤ、氨氮去除率高，对其它排放指标去除率都很高。实践证明Ａ／Ｏ２法用来处理炼油污水是完全可行的，济南炼厂污水处理的成功经验值得推广。

Application of A/O2 Method onto Refinery Sewage Treatment

A/O 2 (Anaerobic/Oxic/Oxic) method test was carried out to probe onto its application onto refinery sewage treatment.The test verified the relationship between NH 3-N volume bear and removing rate,and the effects of dissolved oxygen and oil content upon treatment result.A/O 2 method was feasible to be uesd to process refinery sewage,which had well treated COD,NH 3-N,oil,phenol and SS.The application of A/O 2 method in Jinan Refinery had kept every structure running in gear,made good processing effect and totally reached state's discharging standard.A/O 2 method to treat refinery sewage was methodologically feasible,technically advanced and economically reasonable,which had high removing rates of not only COD,NH 3-N,but also other discharging indexes.Practice proved that A/O 2 method was entirely feasible to be used to process refinery sewage and the successful sewage treating experience of Jinan Refinery was worthy of being popularized.
