چکیده
چکیده مقدمه: آب چرخه خنک سازی نیروگاه شهید مفتح همدان از تصفیه فاضلاب تأمین میگردد. لذا کنترل شیمیایی آب به منظور کنترل خوردگی در چرخه اهمیت بالایی دارد. روش: نتایج آزمون TBC اب چرخه خنک کن نشان دهنده تعداد تقریبی کلونی باکتری برابر با cfu/ml10³ بوده که در بازه پایین قرار دارد. از سوی دیگر بر اساس نتایج آزمون های میکروبی میزان باکتریهای TRB، IRB و APB بسیار بالا و دارای مقادیر cfu/ml 1200، 2300-500 و 10⁵ می باشد. استفاده از آب تصفیه فاضلاب به عنوان تغذیه خنک سازی به دلیل وجود غلظت بالای یون کلسیم منجر به تشدید رسوب گذاری و افزایش رشد میکروبی میگ ردد. همچنین وجود نیترات بالا نیز به دلیل منشاء فاضلاب آب تامین کننده قابل پیش بینی بوده که این مقدار نیترات باعث تشدید باکتری های احیا کننده نیترات و نیتریت می گردد. از طرفی، وجود فسفات و سولفات بالا در نمونه نیز باعث افزایش رسوب گذاری و تشدید رشد میکروبی به ویژه باکتری های احیا کننده سولفات در نمونه همراه خواهد بود. یافته ها: در نتیجه غلظت های بالای باکتری های TRB، IRB و APB در اولویت اول می بایست به صورت انتخاب گزین حذف گردند. در اولویت دوم، یون های نیترات و سولفات که خوراک باکتری های NRB و SRB می باشند با روش های انتخاب گزین حذف یون های نیترات با استفاده از رزین های تبادل یون و سولفات با روش احیا بیولوژیکی می بایست حذف گردند. با توجه با بالا بودن عوامل میکروبی TRB، IRB و APB و همچنین بالا بودن غلظت خوراک عوامل میکروبی، به عنوان اولویت سوم روش های بر پایه زیست کش های غیر اکسید کننده در دستور کار قرار می گیرد.

چکیده [English]
Abstract Introduction: The water of cooling tower for Shahid Moftah power plant is supplied from treated wastewater. Therefore, chemical control of water in order to control corrosion in this cycle is very complicated. Methods: The results of the TBC (total bacteria count) test of cooling tower indicate the approximate number of bacterial colonies equal to 103 cfu/ml, which is in the light range. According to the microbial tests, the amount of TRB, IRB and APB bacteria is very high and has values of 1200, 500-2300 and 10⁵ cfu/ml, respectively. Using treated wastewater as a feed of cooling tower due to the presence of high concentration of calcium ions leads to intensification of sedimentation and increase the growth of microbial organism. Moreover, the presence of high nitrate is predictable due to the origin of water supply, which causes the increase of nitrate and nitrite reducing bacteria (NRB). On the other hand, the presence of high phosphate and sulfate in the sample increase sedimentation and intensify microbial growth, especially sulfate-reducing bacteria (SRB) in the sample. Findings: As a result, high concentrations of TRB, IRB, and APB bacteria is required to be selectively removed in the first priority. In the second priority, nitrate and sulfate ions, which are food for NRB and SRB bacteria, need to be removed by selective removal of nitrate ions using ion exchange resins and sulfate with biological regeneration method. Due to the high level of microbial agents TRB, IRB and APB as well as the high concentration of microbial agents feed, as the third priority, methods based on non-oxidizing biocides needs to be applied in this power plant.
