膜生物反应器处理黄麻生物脱胶废水的实验

Study on the Treatment for Microbial Retting of Jute Fiber Wastewater by MBR

采用水解酸化+膜生物反应器处理黄麻生物脱胶废水。实验结果表明:水解酸化对COD、氨氮有一定去除率,可以提高废水的可生化性。MBR系统在HRT=6h、8h、10h、12h运行时,在HRT=8h时对COD、氨氮的去除率较高,分别为84.8%和80.78%。出水几乎检测不到SS。

Hydrolytic acidification- MBR pwcess is adopted to treat retting wastewater. The results show that hydrolytic acidification can remove COD and NH3 - N and increase the biochemical peifocmance of wastewater; when the reactor works with HRT = 8 h, the removal rate of COD and NH3 - N is high, respectively reaching 84.8% and 80.78% ; and SS almost cant not be found out in the effluent.
