利用液相离子交换法,在天然沸石和人工沸石上吸附金属离子Zn2+、Cu2+和Ag+,制成抗菌沸石,并用其对采出污水进行浸泡处理,进一步评价了用该污水配制聚合物溶液的热稳定性。实验结果表明,用Ag+抗菌沸石处理的污水配制聚合物溶液黏度较未处理污水聚合物溶液的高,Ag+抗菌沸石处理效果也要优于Zn2+和Cu2+抗菌沸石。

Making use of liquid phase ion-exchange treatment, we can crack out the antibiosis zeolite by absorbing the metal ions of Zn2+.Cu2+ and Ag+ on natural zeolite and artificial zeolite, and we do the marinate process on produced water making use of antibiosis zeolite and we further evaluate thermostability of polymer solution confected by produced water. The experiment results show the viscosity of polymer solution confected by Ag+ antibiosis zeolite processed produced water is higher than that of not processed polymer solution, the process effect of Ag+ antibiosis zeolite have the advantage of Zn2+ and Cu2+ antibiosis zeolite.
