Embodiment 1
[0010] Embodiment 1: Several reed curtains woven with fresh reeds are connected into one artificial floating island. The shape and size of the artificial floating island match the shape of the purified water surface, and the area of the artificial floating island accounts for up to 100% of the purified water surface.
Embodiment 2
[0011] Embodiment 2: A number of reed screens woven with fresh reeds are connected into one artificial floating island. The area of the artificial floating island does not completely cover the purified water surface, and a balance block is connected to the bottom of the artificial floating island to maintain the balance of the artificial floating island.

The invention relates to a method for constructing an aquatic plant artificial floating island, which is an artificial floating island formed by connecting a plurality of reed screens braided from reeds into a whole body. The method has the following advantages that: 1, the artificial floating island constructed by using the reeds can effectively absorb and assimilate usable nutrient substances insewage, and hold up and adsorb certain heavy metals and certain harmful substances, and particularly the capability of removing nitrogen and phosphonium can reach up to over 90 percent; 2, new shootsdeveloped on reed nods can transport oxygen to aerobic microorganisms at root zones through photosynthesis and promote the decomposition and the transformation of pollutants in the sewage; 3, the reeds have developed root systems, and after the root systems are connected into a whole body and the whole body is put into water, the constructed floating island has strong stability and is not influenced by the outside environment, such as the influence caused by wind waves; and 4, the process and the management for the construction are simple, and the construction cost is low.
Description
Technical field: [0001] The invention belongs to an environmental protection technology, in particular to a method for purifying water bodies by using aquatic plants. Background technique: [0002] At present, a large amount of nutrient-rich sewage is directly discharged into various water bodies without any treatment, resulting in accelerated eutrophication process. Therefore, the management of eutrophication in river courses and lakes has become the primary issue of environmental governance. In recent years, since aquatic plants can directly absorb and assimilate available nutrients in sewage, and intercept and adsorb some heavy metals and some harmful substances, people have begun to use aquatic plant purification technology to prevent and control eutrophication of water bodies. However, the aquatic plant purification technology generally adopted by people is mainly to put aquatic purification plants such as algae and water hyacinth into the water. These purification pla...
