摘要：
本发明公开了一种保持油田污水配制聚合物溶液粘度的方法，属于采油污水处理技术领域，该方法包括以下具体步骤：油田污水中温度、矿化度、离子、硫化氢含量和硫酸盐还原菌含量的分析；同步脱硫反硝化菌种筛选；同步脱硫反硝化菌种激活剂的筛选；现场试验工艺参数的确定；现场实施，根据室内实验确定出的工艺参数进行现场试验。该方法处理后水中硫化氢含量极低，解决污水中硫化氢造成的聚合物溶液粘度下降问题，能够保持长时间的粘度稳定，节约聚合物干粉的用量，同时该发明安全、环保、成本低和投加工艺简单，能够有效减小污水中硫化氢存在对油田注水开发的不良影响。因此，本发明可广泛地应用于污水保粘处理技术领域中。
摘要（英）：

The invention discloses a method for maintaining the viscosity of polymer solution prepared by sewage in an oil field and belongs to the technical field of oil-producing sewage treatment. The method comprises the following specific steps of: analysis on temperature, degree of mineralization, content of ions, content of hydrogen sulfide and content of sulfate reducing bacteria; screening of synchronous desulfurization and denitrification strains; screening of an activating agent of the synchronous desulfurization and denitrification strains; determination of process parameters of field test; and site implementation according to the process parameters determined by indoor experiments. The method disclosed by the invention has the advantages that after treatment, the content of hydrogen sulfide is extremely low, the problem of reduction of the viscosity of the polymer solution caused by hydrogen sulfide in the sewage is solved, the long-time stability of the viscosity can be maintained, the used amount of polymer dry powder can be saved, simultaneously the method is safe and environment-friendly and is low in cost and simple in adding process, and the bad influence on the development of the sewage in the oil field due to existence of hydrogen sulfide in the sewage can be effectively reduced. Therefore, the method can be widely applied in the technical field of viscosity-maintaining treatment of the sewage.
