油田采油污水处理用絮凝剂研究进展(一)

Research Progress of Flocculants Used for the Treatment of Produced Oily Water from Oilfield

简要介绍了絮凝剂的作用机理,并对近年来国内外油田采出污水处理用絮凝剂进行了综合评述,介绍它们的种类,性能以及近期在实验室和现场的研究及应用情况,指出将来油田采出污水处理用絮凝剂应向环境友好,安全高效的改性天然高分子絮凝剂、微生物絮凝剂和兼具多种功能的水处理剂方向发展。

The research status of flocculating mechanism are summarized, the flocculants used for the treatment of produced oily wastewater from oilfield are also reviewed. The categories, performance and recent research and application development of the flocculants are discussed in detail. In the future, the floeculants used for the oily wastewater should be directed to the modified natural organic polymer flocculants, the biofloeeulants, which are environment friendly, safe and efficient, and also to the wastewater treatment agent with many functions.
