模拟污水中Fe^(2+)、S^(2-)联合腐蚀规律研究

The corrosion regularity of Fe^(2+) and S^(2-) in simulated wastewater

SRB和S2-广泛存在于油田采注系统之中,给油田生产造成了严重的危害和损失,腐蚀产物与Fe2+、S2-相互作用还会带来FeS自燃等多种安全隐患。通过室内模拟实验,研究了模拟污水条件下污水中Fe2+、S2-的联合腐蚀规律,以及有SRB和铁细菌存在时Fe2+、S2-的联合腐蚀规律,实验表明Fe2+、S2-及细菌成为污水腐蚀性增强、悬浮物增加的重要因素。

SRB and S^2-are widespreaded in oil and injection system, caused serious harm and loss to oilfield production,the corrosion and Fe^2＋and S^2-interaction will create spontaneous combustion and other security risks.With simulation experiments to study the corrosion regularity of Fe^2＋and S^2-in simulated wastewater,and the joint corrosion of Fe^2＋ and S^2- while SRB and S^2-exits.Experimental results show that Fe^2＋and S^2-and bacteria become important factors affecting corrosion enhanced andsuspended solids increased.
