| 摘 要： | 采用SBR反应器(厌氧/缺氧/好氧工艺),分别研究了乙酸盐及硝酸盐浓度变化对反硝化除磷的影响特性。试验结果表明,当进水COD浓度>230mg/L时,乙酸盐浓度的变化对释磷、除磷速率等影响并不显著。在硝酸盐浓度<30mg/L时,硝酸盐浓度越高,缺氧段除磷速率也就越高。在C/P>23,C/N>5条件下,SBR系统对磷、氮去除率在90%以上。

| Abstract: | Investigation on the nitrogen and phosphorus removal characteristics was carried by denitrifying dephosphorization responsible for variety of acetate concentration and nitrate concentration respectively in SBR. The experimental results showed that when the influent COD was higher than 230 mg/L,the rate of phosphorus release and uptake have no significant change responsible for variety of substrate concentration and the nitrate concentration was lower than 30 mg/L, the higher the nitrate concentration in anoxic, the higher the rate of phosphorus uptake. In anaerobic-anoxic-aerobic process, under the condition of C/P>23 and C/N>5, more than 90% removal efficiency of phosphorus and nitrogen was observed in SBR system. |
