固定化藻类细胞流动床处理生活污水研究

Research on Immobilized Algae Cell Flow Bed for Treatment Living Sewage

本文采用藻类固定化方法实现了对生活污水除氮脱磷的工艺路线。一方面提高N、P的去除率及氧的保存效率;另一方面解决了藻类细胞的流失现象。本文实验结果表明,在藻类固定化过程中,当藻体用量为0.75gVSS/L且AS,PVA,CaCl2分别为10%,0.6%,2%时,藻体的机械强度、传质及除氮脱磷效果好。

This paper adopt aglae immobilized method ,which realized the technologic course of denitrification dephosphorization. On the one hand , it improved removal rate on N、P and oxygenic preservation efficiency . On the other hand , it solved the phenomenon on algae cell being lost .this paper experiment effect indicate ,on the course of algae immobilized, when Algae=0.75gVSS/L AS=10%,PVA=0.6%,CaCl2=2%, the effect on aglae machine intensity、passed matter and denitrification dephosphorization is the best .
