摘要：

针对我国油田废水处理过程中普遍存在着的费用偏高,处理效果不够理想以及处理后的二次污染问题,采用改性淀粉分别对四种典型油田废水的处理效果,药剂的毒性及其经济可行性进行了系统的考察和分析.研究结果表明,此类化合物的综合评估效果优于聚丙烯酰胺类水处理剂,将其用于石油工业废水的净化处理是可行的.

关键词: 改性淀粉, 油田, 废水处理

Abstract:

Aiming at the problems that agent cost is expensive,clean water efficacy is lesser and water secondary pollution caused by traditional flocculants employed,a starch derivative flocculant is developed and assessed in water treatment efficacy, to xicity and economical reasonableness.The results indicates that the starch polymeric modifier is superior to polyacry lamide flocculants in comprehensive effectiveness.It is practical to use it in the purification of wastewater in oilfields.

Key words: starch polymeric modifier, oil field, wastewater treatment
