Abstract:

以陆生观叶植物红叶甜菜为材料研究其对不同富营养化水体氮磷的去除。在冬季低温条件下,采用浮床无土种植方法,以鱼塘、华家池和污水处理厂二级出水3种水体代表不同类型的富营养化水体,在其中种植红叶甜菜去除水体中N、P,以实现在有景观效果的同时净化水体。结果表明,红叶甜菜对这3种污水中不同形式的氮磷都有较好的去除效果。在试验结束时,对鱼塘水体TN、NH+4-N、NO-3-N、PO3-4-P和TP去除率分别达到了85.72%、85.41%、93.70%、92.64%和84.24%;对华家池水体相应氮磷化合物去除率达到了87.42%、80.62%、87.73%、80.42%和81.74%;对二级出水相应的氮磷去除率分别也达到了49.93%、60.54%、48.45%、59.54%和58.44%。红叶甜菜对各供试富营养化水体表现了良好的适应性。
