Abstract

Abstract:

A cationic water clarifier was synthesized and its structure was characterized by IR and NMR spectra, respectively. The structure of the product was consistent with that of the target product. The water purification performance of the product is evaluated by bottle tests on a petroleum platform in South China Sea. The results show that when the dosage is 14 mg/L, its water purification performance is excellent and the amount of oil in the water of lower layer is 79 mg/L. In comparison with various water clarifiers, it was found that the treatment effect of the product was superior to several other agents.

Key words: oily sewage, cationic, water clarifier

摘要：

合成了一种阳离子型清水剂，并对其结构进行了红外谱图、核磁共振谱图表征分析，结果表明该产品与目标产物结构一致。在南海某油田对其净水性能做了现场瓶试试验，在投加量为14 mg/L时，其净水效果良好，下层水中含油质量浓度为79 mg/L。在和多种清水剂的对比试验中发现，该产品的处理效果优于其他几种药剂。
