چکیده

     افزایش روز افزون فعالیت صنعتی بویژه صنایع مرتبط با ترکیبات نفتی، باعث مشکلات زیست­ محیطی عدید می­ شود. آلودگی منابع آبی، خاکی و هوا منجربه ایجاد صدمات جبران ­ناپذیری به محیط زیست شده است. ازین­ رو، پژوهشگران به دنبال ارائه راهکارهایی جهت احیا و بازیابی این منابع هستند. در این مطالعه، کارایی فرایند هیبریدی شست­وشوی خاک/ ازن­زنی/ راکتور ناپیوسته متوالی در احیای خاک آلوده به آرسنیک و ترکیبات نفتی اطراف پالایشگاه نفت جنوب تهران، مورد بررسی قرار گرفت. تأثیر متغیرهای pH اولیه، زمان واکنش و غلظت سورفاکتانت (Surfactant) در فرایند شست­وشوی خاک (حالت بهینه به ­ترتیب 6/6، 100 دقیقه و 7/47 میلی­گرم بر لیتر) و pH اولیه، زمان واکنش و غلظت گاز ازن در فرایند ازن­زنی (حالت بهینه به­ ترتیب 2، 10 دقیقه و 5 میلی­گرم بر لیتر) و متغیرهای زمان ماند هیدرولیکی، زمان ماند لجن و غلظت اکسیژن (حالت بهینه به ­ترتیب 30 ساعت، 3/6 روز و 36/3 میلی­گرم بر لیتر) توسط روش­ شناسی سطح پاسخ (RSM) بهینه­ سازی شدند. نتایج مشخص کرد که فرایند شست­وشوی خاک می­ تواند 7/1±3/84 درصد از فلز آرسنیک و 2/1±3/82 درصد از کل COD را حذف کند و از فاز خاک به فاز مایع تبدیل کند. همچنین در فرایند ازن­زنی، حداکثر میزان حذف COD برابر با 8/0±0/91 و آرسنیک برابر با صفر درصد بود. در نهایت، فرایند SBR موفق به حذف 16/2±82 درصد آرسنیک 87/2±6/84 درصد از COD شد و غلظت نهایی آرسنیک و COD را به ­ترتیب به 22/5 و 4/297 میلی­گرم در لیتر رسید.

چکیده [English]

 
Today, soil pollution is one the most concerning issues relating to environment (Mishra et al, 2019). Soil pollution leads to transfer of organic and inorganic contaminants to plants and animals and finally to human food chain which causes detrimental effects on human health (Wu et al, 2017). One of the metals that have been used by humans is Arsenic. This metal and its compounds are used in medical and dentistry purposes, electrical industry, pesticide and herbicide industry, alloy manufacturing, etc. Arsenic is one of 10 dangerous elements which is considered a threat to public health by World Health Organization (WHO; Beykpour and Arghavan, 2020). To eliminate and mineralize organic contaminants, multiple processes have been utilized. For example, different oxidizers including Chloride or hydrogen peroxide degrade contaminants throughoxidating agents like hydroxyl and superoxide radicals (Xiao et al, 2015). Moreover, soil washing process was observed to eliminate Cadmium and lead from polluted soil (Feng et al., 2020). Furthermore, biological processes are one of the methods to remediate organic and inorganic pollutants. In this regard, sequencing batch reactor (SBR) is used to treat municipal and industrial wastewater. Due to some special features, this system has gained increasing attention in Europe, China, USA (Jafarinejad, 2017). The purpose of this study is to determine the efficiency of soil washing/ ozonation/ SBR as a hybrid process to remediate polluted soil.
