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PO43--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。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 PO4^3-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 PO4^3-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 PO4^3-P removal efficiency was more than 70%.
