| 摘 要： | 将栅藻包埋固定在筛网上，经饥饿处理，在平行板式生物反应器中对人工污水进行深度净化后，测定藻细胞生长期和饥饿时间对NH4^＋-N和PO4^3-P去除效率影响以及净化前后藻细胞生理变化的结果表明，生长静止初期藻细胞的氮和磷去除率高于对数期的，细胞饥饿48h的氮和磷去除率大于饥饿24和12h，第2个循环中处理4h的氨氮和磷的去除率可分别达到90％和70％以上。 |

| Abstract: | Scenedesmus sp.cells were immobilized on alginate screens for wastewater treatment.Under the conditions of starvation and wastewater treatment cycles,the effects of algal ages and starvation on the NH4+-N and PO43--P removal efficiencies were studied.The results showed that cells in quiescent stage had higher removal efficiency than that in logarithmic phase.After 48 h starvation,the NH4+-N and PO43--P removal efficiencies were higher than which after 24 and 12 h starvation.And in the second starvation and wastewater cycle,NH4+-N removal efficiency exceeded 90%,while PO43--P removal efficiency was more than 70%. |
