含聚污水中所含的Fe2+、S2-等还原物质和细菌对聚合物溶液有降解作用,直接用含聚污水配制聚合物溶液影响聚合物溶液的驱油效果.利用曝氧、杀菌及曝氧与杀菌相结合的3种技术,对含聚污水进行处理,再用处理过的含聚污水稀释聚合物溶液,测量稀释后聚合物溶液黏度的变化,分析曝氧和杀菌对含聚污水稀释聚合物溶液黏度的影响.实验表明,采取曝氧(10 min)及投加杀菌剂(40 mg/L)相结合的处理方法,能明显地提高所稀释聚合物溶液的黏度,并改善其稳定性,与采用单一的曝氧或杀菌技术处理污水相比,所稀释聚合物溶液黏度稳定性更好,黏度下降率仅为9.26%.%Fe2+, S2-and other reducing substances and bacteria in polymer contained waste-water, which have the degradation effect to polymer solution. Direct use of poly containing wastewater can affect the effect of polymer solution. Three kinds of treatment technologies were combined,which were oxygen exposure, sterilization, oxygen exposure and sterilization . The polymer solution was treated by the polymer contained wastewater, and the viscosity of polymer solution was measured. The experimental results show that the combination of sterilization (40 mg/L) with oxygen exposure(10 min), can significantly improve the viscosity and improve the stability of dilute polymer solution,and it is more stable than the single aera-tion or sterilization technology. The viscosity decrease rate is only 9.26%.
