This study investigated the occurrence and removal of 12 antibiotics (ciprofloxacin, enrofloxacin, levofloxacin, norfloxacin, nalidixic acid, azithromycin, clarithromycin, roxithromycin, lincomycin, novobiocin, sulfamethoxazole, trimethoprim) at four sewage treatment plants (STPs): two STPs in Kyoto, Japan and two STPs in Beijing, China. The STPs differed in design and operation conditions, uti...

صنعت تولید نساجی یکی از صنایع است که با توجه به افزایش جمعیت در کشور ما نیاز به گسترش و توسعه دارد. در کنار توسعه این صنعت یکی از مشکلات مهمی که در این زمینه وجود دارد خطرات ناشی از تخلیه پساب غیر استاندارد به آبهای زیرزمینی و سطحی است که بهداشت عمومی را به مخاطره می اندازه. لذا مطالعه کیفیت فاضلاب خروجی کارخانجات ریسندگی و بررسی عملکرد تصفیه خانه های موجود دارای ضرورت می باشد.در این مطالعه برآ...
in this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. for nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...

Although biological treatment of sewage by activated sludge or trickling filters is widely practiced, these processes still give rise to difficulties. The difficulties may be due to sludge bulking during the activated sludge process or to clogging during the operation of trickling filters. In his studies of biofilters and standard filters, H. Heukelekian (Sewage Works J. 17:23, 516, and 743, 19...
