摘要
介绍了国内外油田污水处理用的高分子絮凝剂的种类、使用性能和应用进展情况。研究发现:与阳离子型和阴离子型高分子絮凝剂相比,两性离子型高分子絮凝剂具有pH值适应范围宽、抗盐性好、絮凝及沉降脱水能力强等应用特点。提出了油田污水处理用高分子絮凝剂的发展方向。
This paper introduces the types, performances and application of macromolecular flocculating agent for produced water treatment in the world. Compared with cat-ionic and anionic macromolecular flocculating agent, zwit-terionic macromolecular flocculating agent has the advantages of wide adaptability range to pH value, good salt resistance, and strong capability of flocculation and precipitation and dehydration. Development trend of macromolecular flocculating agent for produced water treatment is presented.
