化学氧化强化混凝的机理及其油田含聚污水上的应用

摘要

随着三次采油技术的应用，油田污水中含有大量的聚合物。含聚污水处理通常采用以混凝和过滤为主，但由于聚合物的存在，混凝效果达不到要求。化学氧化具有助凝和破乳的作用，氧化剂投加在常规含聚污水处理工艺的混凝前，不改变常规工艺，可显著提高混凝效果，在实际工程上有一定的应用优势。%After application of the tertiary oil recovery technique, oilfield wastewater contains a large number of polymers. The treatment methods of polymer-containing wastewater usually focus on coagulation and filtration, but the coagulation efficiency cannot meet the requirements because of the presence of polymer. Chemical oxidation processes have the functions of coagulation and demulsification. Adding oxidizing agent before coagulation process in conventional polymer-containing wastewater treatment process, can significantly improve the effect of coagulation.
