摘要
通过实验研究缺氧反硝化聚磷 ,揭示DPB细菌在厌氧和缺氧交替环境下的厌氧释磷、缺氧反硝化吸磷及CODCr变化规律。结果表明 ,DPB细菌在缺氧条件下可利用NO-3 作最终电子受体进行吸磷 ,其吸磷效果及反硝化速率高于常规脱氮除磷工艺。
The laboratory study on anoxic denitrifying dephosphatation revealed the regularity of COD Cr and how the DPB bacteria take up or release phsphate under both anaerobic environment and anoxic environment by turns.It showed that the DPB bacteria under anoxic environment employ the nitrate as the electron acceptor to uptake phosphate ,and better effciency of phosphorus uptaking and faster rates of denitrifying were observed.
