摘要：
介绍了黏度法与浊度法测定三次采油污水中聚丙烯酰胺(PAM)的残余浓度和次氯酸盐法及化学凝沉法去除PAM的原理和方法，并对影响因素及技术可行性进行了探讨。结果表明:当测定温度在2～22℃范围内，浊度法受溶液中可溶性盐和有机物以及环境温度的影响比黏度法要小，结果的重现性好，适合于含油污水PAM浓度的检测。化学凝沉法可快速去除三次采油废水中残留的PAM，处理工艺简单，水质可以达到油田回注水或外排水的标准。

Abstract:
Viscosimetry and turbidimetric glacial acetic acid/sodium hypochlorite method for determining PAM concentration in aqueous solutions involved in enhanced oil recovery(EOR)operations have been investigated. It is shown from the experimental results that turbidimetric glacial acetic acid/sodium hypochlorite method is superior to viscosimetry due to little influence on environment, ion intensity and organic substance, and it has high reproducibility and stability at ordinary temperature. So it can be applied to fieldwork expediently. At the same time two methods on removal of PAMhave been studied. It’s found that hypochlorite method is the only one applied to purer water, whereas bychemical coagulation method PAMfromoil-field wastewater can be removed easily, and the treated water qualitycan meet the need ofreinjection water in the oil-field and the requirement ofdischargingstandard.
