摘　　要：报道了实验室条件下利用活性藻反应系统对合成污水中N、P、CODCr和BOD5等的去除 效果.在26±2℃条件下,当停留时间为24h时,TN, TP, CODCr 和BOD5 的平均去除率分别为 7 7.62%, 33.23%, 90.89% 和 95.77%.当进水负荷加大一倍、停留时间相应缩短、光强、水温 同时减弱和降低时,该系统对TP 和BOD5的处理效果受到明显影响,对 CODCr的处理效果影响 不大,运行条件的改变基本上不影响活性藻系统对TN的处理效果,两种运行条件下,TN的平均 去除率分别为77.62%和77.86%.A laboratory scale activated algae-reaction system was used for the removal of nitrogen, phosphorus, chemical oxygen demand(CODCr) and biological oxygen demand(BOD5) from artificial wastewater. The mean removal rates of TN, TP CODCr and BOD5 were 77.62%, 33.23%, 90.89% and 95.77% respectively at retention times of 24h and temperature of 26±2°. When the hydraulic load was increased from 25 to 50L/d, and the retention time decreased correspondingly from 24 to 12h with the water temperature and the light intensity decreased, its treatment efficiency on TP and BOD5 was markedly effected, while that of CODCr was effected very little. It's treatment efficiency on TN was not effected basically the operation conditions had been changed; and the mean removal rates of TN were 77.62% and 77.86% respectively.
