油田含油废水处理絮凝剂的研究与应用

The research and application of flocculants used for the treatment of oil-bearing wastewater from oilfield

对国内外石油和石化行业含油废水处理常用絮凝剂进行了综合评述 ,较详细地介绍了它们的种类 ,使用性能和近期研究及应用进展情况 ,与无机、有机絮凝剂相比 ,复合絮凝剂具有效率高、实用范围广等优点。未来含油废水处理絮凝剂应向无毒 ,易生物降解的天然高分子改性絮凝剂。

The flocculants used for the treatment of oil-bearing wastewater from oilfield and refinery are reviewed. The categories performance and recent research and application development of the f1occulants are discussed in detail.Complex flocculants exhibit some advantages of high efficiency and wide application field over the inorganic and organic flocculants. In the future, the flocculants used for the oil-bearing wastewater should be directed to the modified organic high polymer flocculants from natural, the microbial flocculants, which are poisonless and easy to be decomposed, and also to the wastewater treatment agent with many functions.
