摘要
介绍了无机、有机与微生物3类型絮凝剂的分类情况。综述了国内外在絮凝剂领域研究与应用的发展现状,阐述了各类型絮凝剂处理油田废水的优势和缺点,结合采油废水的复杂情况,分析了已使用的絮凝剂在达标治理过程中存在的问题,并探讨了开发廉价、高效、可降解絮凝剂的发展趋势。
In this paper three types of flocculants-inorganic, organic and microbial are introduced. The development in research and application of the three types at home and abroad are discussed. Then the advantages and disadvantages of each type of flocculants are analyzed respectively. Combined with the complicated situation of oil extraction wastewater, the application of flocculants to wastewater treatment is reviewed. Finally the research trend of cheap, efficient and biodegradable flocculants is probed.
