摘　　要：分别采用悬浮藻和固定藻处理鸡粪厌氧发酵液，在不同的季节和温度条件下进行试验，结果表明，藻类对沼液中的ＮＨ＋４Ｎ、ＴＰ等污染成分有较高的净化效率。处理后，悬浮藻对污染物的平均去除率为：ＮＨ＋４Ｎ６２４％，ＴＰ６２７％；固定藻对污染物的平均去除率为：ＮＨ＋４Ｎ８４０％，ＴＰ７３８％。试验结果稳定。Floating algae and fixed algae were employed respectively to treat the anaerobically digested wastewater of chicken waste.The tests were conducted in different seasons and under different temperature.The results show that wastewater purification efficiency is high.After treatment,the average removal rate of pollutant in floating algae are:NH + 4—N 84 0%、TP 62 7%;and NH + 4—N 84.0%、TP 73.8% in fixed algae.
