油田污水处理剂研究进展

Research progress of oilfield wastewater treatment agents

随着水资源短缺矛盾的日益严重以及人们环保意识的不断增强,油田污水处理剂的研究及应用将会越来越受到重视。目前油田污水处理剂主要包括预脱水剂、反相破乳剂以及絮凝剂,其中絮凝剂又包括无机型絮凝剂、有机型絮凝剂、微生物型絮凝剂以及复配型絮凝剂。介绍了每一类油田污水处理剂的分类、净水机理、优缺点、应用情况等,并提出了油田污水处理剂的发展方向。

With the increasingly serious contradiction of water resources and the increasing awareness of environmental protection,the research and application of oilfield wastewater treatment agents will be received more and more attention.At present,oilfield wastewater treatment agents include pre-dehydrating agents,demulsifiers and flocculants.The flocculants are divided into inorganic flocculants,organic flocculants,microbial flocculants and compound flocculants.This article introduces the classification,water purification mechanism,advantages and disadvantages,application of each type of oilfield wastewater treatment agents,and puts forward the development direction of oilfield wastewater treatment agents.
