چکیده مقاله:

toxic gases such as H2S , mercaptane have negative effect on waste water treatment performance and also make persecutor odour in environment after releasing in atmosphere and sudden rising amount of them as a shock , causes bateria death in activated sludge system. in B andar abbas refinery waste water tratment unit existance of these gases specialyy H2S has caused bacterial death and then high bulcking in biological surface and decreased COD Removal yield. even by existance of equaliztion process before AST system aerating system large amount of gases left to AST system. so due to this problem , lab test for suspected stream that contains the large amount of these gases specially H2S to find out the stream and amoung of gases was performed and then falsh process for remove these gases befor WWT unit was designed and then predicted recomended process was simulated by ASPEN HYSYS software to check removal potential and provide best condition to increase removel efficiency by means of case study by software. then the best process condition selected and approved for construction in desalter water line befor entering to WWt unit.
