采油废水中硫酸盐还原菌Fe(Ⅵ)杀灭试验

摘要

An experiment was conducted to eliminate Sulfate Reducing Bacteria (SRB) by Fe( VI) in oil production wastewater, which can cause corrosion, scale and barricade to water injection system. Result shows that Fe( VI) has a strong ability to eliminate SRB. Hie optimal operating conditions were obtained as Fe( VI) dosage 10 mg/L, reaction time more than 10 min, and control index (Ct) over 100 mg · min · -1.%采油所产生的废水中产生的硫酸盐还原菌(SRB)可造成注水系统的腐蚀、结垢和阻塞,严重影响原油的开发与生产.以Fe(Ⅵ)作为氧化型杀菌剂杀灭SRB,试验结果表明:Fe(Ⅵ)对SRB具有很强的灭菌能力；Fe(Ⅵ)投加量C＞10 mg/L时就能满足回注水的要求;适宜的接触反应时间为t＞10min;相应地有Ct＞100 mg·min·L-1.
