Method for purifying nitrogen in nitrogenous water body by using combined farmland ecosystem

The invention discloses a method for purifying nitrogen in a nitrogenous water body by using a combined farmland ecosystem, and relates to the technical field of water treatment. According to the invention, the paddy field wetland and the ecological floating bed are combined to form a farmland ecological system for in-situ remediation, and efficient bioremediation of a nitrogen-containing water body can be realized, so that the effects of purifying water quality and further solving water body eutrophication are achieved. The combined farmland ecosystem disclosed by the invention not only can enhance the removal effect of nitrogen in surface water, but also can generate certain economic benefits, and is a novel in-situ remediation technology according with reality. 本发明公开了一种利用组合农田生态系统净化含氮水体中氮的方法，涉及水处理技术领域。本发明将稻田湿地与生态浮床相结合组成原位修复的农田生态系统，可实现对含氮水体的高效生物修复，从而达到净化水质进而解决水体富营养化的效果。本发明的该组合农田生态系统既能增强对地表水中氮的去除效果，又能产生一定的经济效益，是一种新型的符合实际的原位修复技术。
