Assessment and Control of Microbial Induced Corrosion in Sae Water in Nuclear Power Plant Materials 核电站材料中Sae水中微生物腐蚀的评价与控制

Microbial-induced corrosion (MIC) can occur due to the long building timeframes connected with nuclear facilities and the huge number of redundant or standby systems where water is permitted to remain stagnant for long periods of time. MIC affects carbine and low-alloy steels, stainless steels and copper alloys are all susceptible to MIC in raw water applications. Visual examination is especially helpful in performing preliminary assessments of MIC. If properly diagnosed, MIC can be effectively treated during plant development, operation and brief shutdowns. The main aim of this work is directed to investigate some methods for evaluating and controlling one of the most important economic problems arose from the presence of some microorganisms which are responsible for promoting corrosion process of metals and/or their mixtures (alloys) in cooling water systems and those in different Egyptian industrial fields such as power stations, oil fields and power plants. The study concentrated on finding applicable treatment methods for controlling Thiobacillus bacteria which represent one of the important active members of microbiologically induced corrosion (MIC) group found in seawater, through recording their growth and reducing their activities, and consequently reducing the harmful impact of its presence in different industries as mentioned above.The current research is also concerned with the scales formation studies for water and the effect of scales inhibitors on the scales formed during cooling processes. Moreover, this research includes and discusses the results of using some special biocides as a chemical method applied for reducing microbial counts and its efficiencies on Thiobacillus bacteria. Benzalkonium bromide, Sodium hypochlorite and Gluteraldehyde were chosen for the present study because of their broad spectrum and biodegradability. A strategy is developed for inhibiting Thiobacillus bacterial colonization and aerobic corrosion in biofilms on mild steel. The most effective biocide was gluteraldehyde that has been used as a reference biocide, its addition firstly prior to Thiobacillus bacterial colonization considered a valuable approach to reduce Thiobacillus bacterial induced corrosion. Gluteraldehyde form biocide which has wide a range of biocidal effects and also inhibiting Thiobacillus bacteria as shown in this study. The results indicated that 50 (mg/L) of Glutaraldehyde was sufficient to eliminate all bacterial counts, but 2.5 (mg/L) of Benzalkonium bromide and 8 (mg/L) of sodium hypochlorite were also required to achieve the same result. The results also demonstrated that high biocide concentration inhibit Thiobacillus bacteria growth more than the low biocide concentration. Finally, the findings support the construction of nuclear power plants in order to prevent aerobic bacteria from causing bio corrosion and to provide media for the growth of anaerobic bacteria such as sulphate reducing bacteria which were previously thought
微生物诱发腐蚀(MIC)可能是由于与核设施相连的建筑时间框架较长,以及允许水长时间滞留的大量冗余或备用系统。MIC影响卡宾枪和低合金钢,不锈钢和铜合金在原水应用中都容易受到MIC的影响。目视检查对MIC的初步评估尤其有帮助。如果诊断正确,MIC可以在工厂开发、运行和短暂停工期间得到有效治疗。这项工作的主要目的是研究一些方法来评估和控制由一些微生物的存在引起的最重要的经济问题之一,这些微生物负责促进冷却水系统中金属和/或其混合物(合金)的腐蚀过程,油田和发电厂。该研究的重点是通过记录硫杆菌的生长并降低其活性,从而减少其在上述不同行业中的有害影响,找到控制硫杆菌的适用处理方法,硫杆菌是海水中微生物诱导腐蚀(MIC)群的重要活性成员之一。目前的研究还涉及水的水垢形成研究以及阻垢剂对冷却过程中形成的水垢的影响。此外,本研究还包括并讨论了使用一些特殊的杀生物剂作为减少微生物计数的化学方法的结果及其对硫杆菌的效率。苯扎溴铵、次氯酸钠和戊二醛由于其广谱性和生物降解性而被选择用于本研究。制定了一种策略来抑制硫杆菌在软钢生物膜中的定植和好氧腐蚀。最有效的杀生物剂是戊二醛,它被用作参考杀生物剂,在硫杆菌细菌定殖之前首先添加它被认为是减少硫杆菌细菌诱导腐蚀的一种有价值的方法。如本研究所示,谷氨酸形成杀生物剂,具有广泛的杀生物作用,并能抑制硫杆菌。结果表明,50(mg/L)戊二醛足以消除所有细菌计数,但也需要2.5(mg/L)苯扎溴铵和8(mg/L)次氯酸钠才能达到同样的结果。结果还表明,高杀菌剂浓度比低杀菌剂浓度更能抑制硫杆菌的生长。最后,这些发现支持了核电站的建设,以防止好氧细菌引起生物腐蚀,并为厌氧细菌(如硫酸盐还原细菌)的生长提供介质,硫酸盐还原细菌以前被认为是参与生物腐蚀的最重要的细菌群。
