浅谈污水处理过程中配制聚合物溶液粘度研究

45℃反应30 d内,120 mg/L稳定剂稳定处理后中十二站污水和未经处理的北1-J3-P49井口采出污水配制的聚合物溶液的粘度保留率89.2～107%,并随反应时间的延长粘度保留率值有增高的趋势。添加120 mg/L稳定剂聚驱具有代表性北1-Ⅱ污水站污水配制的1200 mg/L聚合物溶液,5～1000 S-1上、下行剪切速率条件下的抗剪切性能优于污水直接的聚合物溶液,且随反应时间的延长,添加稳定剂污水配制的聚合物溶液抗剪切性能相对污水直接配制的聚合物溶液更加显著,稳定剂稳定聚合物溶液效果良好。仅添加120 mg/L稳定剂污水配制的聚合物溶液,30 d的粘度保留率89.2～107%,稳定剂稳定污水配制聚合物溶液的效果良好,且5～1000 S-1上、下行剪切速率条件下的抗剪切性优于污水直接的聚合物溶液,可以推测添加稳定剂污水配制的聚合物溶液的实际调驱效果好于污水直接配制的聚合物驱替液。

Research on Viscosity of Polymer Solution Prepared in Sewage Treatment Process

We researched on viscosity of polymer solution prepared in sewage treatment process o The result indicated that 30d viscosity retention rate of polymer solution prepared by 120 mg / L stabilizer sewage was 89. 2 to 107%. It is conjectured that actual displacing effect of the polymer solution adding stabilizer sewage was better than polymer displacement fluid prepared by sewage directly.
