چکیده

در سال‌های اخیر، حضور ترکیب‌های دارویی در محیط زیست به علت تأثیر نامطلوب آن بر ارگانیسم‌های مختلف، توجه بسیاری را به سوی خود جلب کرده است. در نتیجه، نگرانی‌ها به علت ورود این ترکیب‌ها به محیط زیست رو به افزایش است و در سال‌های اخیر مطالعمطالعه‌ها روی یافتن راه‌های جدید و کارآمد برای حذف مؤثر این ترکیب‌ها از خروجی واحدهای تصفیة پساب متمرکز شده است. یکی از روش‌هایی که در سال‌های اخیر به آن بسیار توجه شده است، استفاده از فناوری آب زیربحرانی و فوق‌بحرانی برای از‌میان‌بردن ترکیب‌های آلی است. در پژوهش پیش رو تخریب سه مادة دارویی کاربامازپین، متوپرولول و سولفامتوکسازول با استفاده از آب زیر و فوق‌بحرانی در رآکتور ناپیوسته در محدودة دمایی °C500-250 و مدت‌زمان 5 الی 50 دقیقه بررسی شد. در اکثر موارد، درصد حذف داروهای ذکرشده بیش از 90 درصد بود که این میزان حذف از روش‌های مرسوم بیشتر است. همچنین نشان داده شد که حذف بهینة داروهای کاربامازپین، متوپرولول و سولفامتوکسازول به ترتیب در دماهای °C350، °C400 و °C300 و مدت‌زمان 20 دقیقه صورت پذیرفت. در نهایت، نتایج حاصل نشان می‌دهد که فناوری آب زیربحرانی و فوق‌بحرانی می‌تواند به عنوان گزینة مناسبی برای حذف مؤثر ترکیب‌های دارویی از واحدهای تصفیة پساب مطرح شود.

چکیده [English]

The presence of pharmaceutical compounds in the environment and waste streams has received lots of attention in recent years due to its adverse effects on the health of different organism. The emerging of these compounds in the environment is a growing concern and recent researches have focused on finding new ways for enhancing the pharmaceutical compound’s removal efficiency in the effluent of wastewater treatment plants. Removing organic compounds using sub- and supercritical water technology has gained lots of attention in recent years. In this research paper the application of subcritical and supercritical water technology for destruction of pharmaceutical compounds (carbamazepine, metoprolol and sulfamethaxazole) inside batch reactor in temperature range of 250°C to 500°C with different residence times of 5 to 50 minutes was investigated. Using this treatment method more than 90% of above-mentioned compounds were destructed that is higher than the conventional methods. It was shown that carbamazepine, metoprolol and sulfamethaxazole are optimally destructed in 20 minutes at 350°C, 400°C and 300°C, respectively. Consequently the results of the study illustrated that this technology can be used as an alternative for efficient removal of pharmaceutical compounds from wastewater treatment plants.
