| 摘 要： | 为了提高SBR反应器脱氮除磷的效率,研究采用SBR反应器进行了长期连续实验,考察不同浓度Cu^2＋对COD、NH4^＋-N及PO4^3--P去除效率的影响。结果表明：在反应器达到稳定运行状态后,添加Cu^2＋浓度为0 mg/L、1.0 mg/L及10 mg/L时,COD去除率分别为87.43%、88.20%与33.47%,NH4^＋-N去除率分别为70.8%、70.8%与35.95%;PO4^3--P去除率分别为90.54%、92.47%与11.11%。当Cu^2＋浓度≤1 mg/L时,对COD和磷酸盐的去除具有一定的促进作用,当Cu^2＋浓度〉1mg/L时,则产生抑制作用。

| Abstract: | In order to improve the removal efficiency of nitrogen and phosphorus,a long-term continuous experiment was carried out and the effect of copper ions on removal efficiency of COD,N and P were investigated by using SBR at different copper ion concentrations. The results show that the removal efficiency of COD is 87.43%,88. 20% and 33. 47% when the copper ion concentration were 0 mg / L,1. 0 mg / L and 10 mg / L,respectively. Furthermore,removal efficiency of NH4^＋- N is 79. 18%,70. 8% and 35. 95%,and removal efficiency of PO4^3-- P is 90. 54%,92. 47% and 11. 11%,respectively. A low concentration of Cu^2＋plays a promoting role for the removal of COD and phosphates,but a high concentration of Cu^2＋plays an inhibition role. |
