| 摘 要： | 通过实验研究缺氧环境倒置，来比较对Ａ／Ａ／Ｏ工艺脱氮除功能的影响。结果表明，与常规Ａ／Ａ／Ｏ（厌／缺／好）工艺相比，倒置后的工艺具有更好的脱氮除磷效果，在同等条件下，倒置系统的出水中ＰＯ４＾３－Ｐ明显降低，而比反硝化速率却可３０－５０％，该文还进一步揭示了聚磷微生物在各种环境下的释磷和吸磷规律及其相互关系。

| Abstract: | The laboratory study on influence of reverse of anaerobic and anoxic zone on the biological denitrifica-tion and phosphorus removal process showed that in comparison with the conventional A/A/O process Anaerobic (A1)/Anoxic(A2)/Aerobic(O)], the reverse A/A/O process (A2/A1/O) has better effciency of denitrification and phosphorus removal. Under equivalent conditions, the effluent PO43--P content of the system with A2/A1/O was lower than that of A1/A2/O, whereas the specific rate of denitrification was 30% - 50% higher. It also revealed that regularity of P-release and P-uptake under different environment and their mutual relationship. |
