摘要
以赵王河水为原水,在初秋和秋末冬初对以香蒲、睡莲、芦苇、鸢尾、美人蕉为栽培植物的水培样净化微污染河水的状况进行了初步研究。结果表明,初秋,各水培植物处理下河水高锰酸盐指数增加,鸢尾最高,各植物对河水TN去除都有效果,睡莲最高,去除率在30%~40%之间,植物存在对TN处理很重要,植物对TP作用较小。秋末冬初,植物在良好保温下可继续生存,但受植物内部生长节律的影响,植物对河水净化作用较小。
In the early autumn and the late autumn,five hydroponic macrophyte species(Typha angustifolia,Nymphaea tetragona,Phragmites communis,Iris tectorum Maxim,Canna indica) were used to deal with slightly polluted water from the Zhao Wang river.The results show that: In the early autumn,CODMn in the hydroponic experiment increase,iris most strongly.Each plant to total nitrogen has certain processing power,Nymphaea tetragona most strongly.The removal rate of TN is between 30% and 40%,and the existence of TN processing plant is very important.For TP,the role of plants is limited.In the late autumn,plants can continue to survive in good insulation.But by the effect of the plant internal growth rhythm,purification of plants to the river is limited.
