摘要: 介绍了BIOFOR反应器在江西某医药集团混装制剂废水处理中的工程应用。采用自然挂膜和接种挂膜相结合的方式快速启动BIOFOR池。BIOFOR池处理混装制剂废水具有良好的效果、较高的耐冲击负荷能力、运行稳定。COD平均去除率达72.45%,NH3-N平均去除率达56.8%。BIOFOR池出水可稳定达GB 21908—2008《混装制剂类制药工业水污染物排放标准》。BIOFOR池处理混装制剂废水的最佳运行气水比为5∶1。反冲洗宜采用水气联合反冲洗。Abstract: The recent research progress of highly hydrophobic membrane technology was reviewed in treating the oil-water emulsion wastewater,methods to the treatment and demulsification of the oil-water emulsion wastewater were introduced,the mechanism of the hydrophobic membrane phase splitting and demulsification was focused on,the influencing factors of hydrophobic membrane oil-water separation were discussed. Some directions of highly hydrophobic membrane in treating the oil-water emulsion wastewater in the future are finally proposed.
