Stirenin Biyolojik Giderim Performansının Araştırılması

Abstract

Divinil benzen (stiren) kimya endüstrisinde geniş çapta kullanılan zenobiyotik organik bileşiklerdendir. Bu yüzden kimya endüstrilerindeki atıksu ve atıkgazlardan bu bileşiğin etkili ve ekonomik giderimine ihtiyaç duyulur. Bu çalışmada stirenin karışık kültür ile aerobik şartlar altında biyolojik giderim performansı incelenmiştir. Denemeler kesikli şartlarda 50-150 mg L-1stirenin farklı başlangıç konsantrasyonları için yürütülmüştür. Mikroorganizmaların büyümesi üzerine organik bileşiklerin konsantrasyon etkisi araştırma süresince çalışılmıştır. Sonuç olarak kesikli işletme şartlarında kullanılan karışık kültürün stiren gideriminde oldukça yüksek performans gösterdiği belirlenmiştir. Karbon ve enerji kaynağı olarak bu bileşikleri kullanan kültür başarılı bir şekilde stireni giderebilmiştir

Investigation of The Biological Removal Performance of Styrene

Abstract

Divinylbenzene (styrene) are among the xenobiotic organic compounds that are widely used in

chemical industries. For this reason, it is necessary to effectively and economically remove these compounds from

the waste waters and effluent gases of chemical industries. In this study, the performance of mixed cultures for the

biological removal of styrene mixture was investigated under aerobic conditions. Batch experiments were conducted

with different initial concentrations of styrene (50-150 mg L-1). The effect of the concentration of these organic

compounds on the growth characteristics of the microorganisms was studied during the conducted research. In conclusion,

mixed cultures were identified to perform highly satisfactorily in the removal of styrene in batch operating

conditions. The culture has successfully removed styrene using these compounds as the carbon and energy source.
