高碳醇类消泡剂在炼化常减压工艺污水中的应用研究

Application Research of Higher Alcohols Antifoaming Agent at Atmospheric and Vacuum Distillation Refinery Wastewater Treatment

对本单位开发的高碳醇类消泡剂,在某厂常减压工艺装置污水中进行了应用研究。对消泡性能、COD贡献量、活性污泥友好性等进行了测试研究。并在污水处理现场进行了消泡剂的应用测试。测试结果表明,此高碳醇类消泡剂能够有效解决常减压工艺污水的泡沫问题,且对COD处理不增加压力,对生化污泥不会造成运行影响。

A kind of higher alcohols antifoaming agent is used in petrochemical refinery wastewater treatment meaner biological reactor. Research progress of agent use the water from some refinery wastewater treatment to research the antifoam performance, agent toxicity for activated sludge. The antifoaming agent is used in some petrochemical for Application research. The result of research makes clear that the antifoaming agent can solve the foam problem in refinery wastewater, and be friendly for COD and activated sludge.
