固定化微生物降解油田废水技术评述

Review of Immobilized Microorganism Technologies for Oilfield Wastewater Biodegradation

固定化微生物技术因处理效率高、抗冲击能力强、固液分离效果好、污泥产生量少等优点而广泛用于难降解有机废水的处理。文章简要介绍了固定化微生物技术的起源,发展过程,制备材料和方法,特点和优点;对其高效降解油田废水的机理进行了分析,综述了固定化微生物技术在高盐采油废水、稠油废水、舍聚废水、石油污染地表水等油田废水处理中的应用研究,对固定化微生物技术进一步提高油田废水降解效率的研究方向提出了建议。

Immobilized microorganism technology(IMT) has many advantages such as high degradation efficiency,strong antishock function,easy solid-liquid separation and less sludge.IMT has been widely applied to the treatment of refractory organic wastewaters and gradually been developed in the treatment of oilfield wastewater recently.The paper brief reviews the origin,development,prepared methods and materials,characteristic and advantages of IMT,detailsIMT's application to the treatment of oilfield wastewater and analyzesits mechanisms.Suggestions for further improving the degradation efficiency of IMT have been given.
