In this paper, seven kinds of aquatic plants as the main study, including the round of Ceratophyllum demersum Ceratophyllum demersum, Potamogeton Potamogeton distinctus, Phnom Penh, Acorus gramineus Acorus granzineus, rush Aquatic grass, Iris Iris tectorum, mushrooms grass Potamogeton malainus, poly grass Cyperus glomeratus, respectively adult workers in their wetlands to build simulation systems, to carry out different types of aquatic plants in wetland removal efficiency of total nitrogen, through experiments to have higher water purification capacity of the landscape at the same time the effect of both types of aquatic plants, and ultimately the water used in water treatment landscape in. The experimental results show that: (1), Ting-water plants, floating-leaved plants, submerged plants, in addition to the ability of nitrogen followed by Phnom Penh Acorus gramineus> Iris> rush, mushrooms and grass> poly grass, hornwort> Potamogeton in the Landscape Water processed, will be in Phnom Penh Acorus gramineus, mushrooms Ceratophyllum demersum grass and common application of artificial wetland system can achieve the water quality purification, the diversity of plant species at the same time also increased the effectiveness of its landscape. (2), submerged plant nitrogen in addition to high efficiency, to deal with three weeks, Ceratophyllum demersum and Potamogeton water on the total nitrogen concentration decreased from 3.00mg / l and 3.24mg / l, is therefore submerged plants can be applied to be Rapid purification of water quality projects. (3), aquatic plants and denitrification of nitrogen in water of total nitrogen concentration close to trend. (4), aquatic plants in water and ammonia nitrogen concentration of NOx was the shift in the relationship. (5), aquatic plants for removal of ammonia in water between species, but on the total nitrogen removal and denitrification of nitrogen than the existence of significant differences in effect.

Article 7 species of Aquatic plants as the main research object, including round Ceratophyllum algae demersum, goldfish pondweed Potamogeton distinctus Acorus calamus, JinBianShi granzineus, grass, Aquatic buttercups tectorum, mushrooms, Iris Iris malainus Potamogeton grass, grass glomeratus Cyperus, with its constructs simulation system, the artificial wetland in different types of Aquatic plants in total nitrogen removal efficiency of wetland, through experiment with high water purification capacity, at the same time, both the landscape effect of Aquatic plants species, and eventually application in landscape water treatment. Experimental results show that: (1), water plants, plant, water plants in addition to JinBianShi calamus for nitrogen ability > > buttercups and mushrooms grass iris > >, goldfish grass cluster algae pondweed in landscape water treatment, will JinBianShi calamus, mushrooms, grass and common used in the goldfish algae artificial wetland systems, which can realize water purification plants species diversity, at the same time, it also increases the landscape effect. (2), and the submerged plant except nitrogen efficiency, after three weeks of treatment, goldfish and pondweed total nitrogen in water fell to 3.00 mg/l and 324 mg/l, therefore the submerged plant can be used to quickly in purifying water quality in the project. (3), aquatic plants, total nitrogen in water and nitrate nitrogen concentration trend. (4), the aquatic plants in the water of ammonia and nitrate concentrations of nitrogen is reciprocal relationship. (5), aquatic plants for water in the ammonia nitrogen removal of the difference between the total nitrogen, but not for nitrate nitrogen removal and the effect is obvious difference.

The main body of a book is used for 7 kinds hydrophytes studying a marriage partner mainly, dish Potamogeton distinctus , Phnom Penh rhizoma graminei Acorus granzineus , lampwick grass Aquatic grass , fleur Iris tectorum , mushroom grass Potamogeton malainus, gather grass Cyperus glomeratus including wheel cedar moss Ceratophyllum demersum , eye son , establish the manpower wet land simulation system respectively with whose structure, the general nitrogen dislodges effect in the wet land carrying out the different type hydrophyte , purify an ability by the fact that experiment put forward has higher water quality , is utensil landscape concurrently at the same time the effect hydrophyte kind, And ultimate apply to landscape wave water quality is processing. The experiment bear fruit is indicated: (1), straight of water plant, floats to gather grass , cedar moss> eye son in leaf plant , heavy water plant except that the nitrogen ability is Phnom Penh rhizoma graminei> fleur> lampwick grass , mushroom grass in proper order> dish, the wave is processing in landscape, in applying Phnom Penh rhizoma graminei , mushroom grass and cedar moss to manpower wet land system commonly, both and can realize the water quality purification, plant kind diversity has also increased it's landscape effect at the same time. (2), sinks water plant after except that the nitrogen is efficient , handling three cycles , the cedar moss and eye general nitrogen thickness in you dish wave come down right away till 3.00 mg/l and 3.24 mg/l, in sinking water plant therefore but applying to the project requiring a fleetness to purify water quality. (3), in hydrophyte wave, the general nitrogen and saltpetre nitrogen thickness change trend make up to. (4), in hydrophyte wave, the ammonia nitrogen and saltpetre nitrogen thickness assume this eliminating that long relation. The hydrophyte takeoff interspecific crossing difference to ammonia nitrogen in wave is not big (5), the takeoff to the general nitrogen and the saltpetre nitrogen there exists more obvious difference in effect but.
