金鱼藻(Ceratophyllum demersum)对水中氮、磷去除效率初探

随着养殖水体富营养化的加剧,利用生物净化水质受到人们的重视。水生维管束植物以其特有的组织、生态功能及易于人工操纵等特点,在净化水质、防治水体富营养化方面发挥了重要作用。本试验的目的在于研究和探讨水生维管束植物金鱼藻(Ceratophyllum demersum)对水体中氮、磷的去除效率,为水生维管束植物金鱼藻用于净化水质提供科学依据。在试验过程中,通过调控温度、光照等环境条件满足金鱼藻的生长所需。试验结果表明,金鱼藻对水体中NO3-N、NO2-N、NH3-N、PO4-P的去除效果较好;对水生维管束植物进行长效管理,是决定水质净化效果的重要因素。

Preliminary Study on Nitrogen and Phosphorus Removal Efficiency by Ceratophyllum demersum

With the eutrophication exacerbation of culture water, the biological water purification has been paid more attention to. So, the aquatic vascular plants have played important roles in water purification, eutrophication prevention because of their unique organs, ecological functions and the characteristics of easy control and so on. The purpose of this test is to study and explore the nitrogen and phosphorus removal efficiency of the aquatic vascular plants （ Ceratophyllum demersum） , and thus to provide a scientific basis for purifying the water by the aquatic vascular plants （Ceratophyllum demersum） . During the experiment, the growing conditions for Ceratophyllum demersum are satisfied by regulating the temperature and light. The results show that Ceratophyllum demersum has good effects on removing NO3-N, NO2-N, NH3-N and PO4-P. Also, it is the important determining factor for the purification effect to manage the aquatic vascular plants in the long term.
