Background
With the continuous promotion of new rural construction, the rural environment construction becomes an important link, and the water environment construction plays a role in guaranteeing the safety of citizens' drinking water and rural agricultural irrigation water. In recent years, river and lake pollution caused by eutrophication problems is one of the current major environmental problems, which is mainly reflected in that the concentrations of nutrient substances such as nitrogen and phosphorus in rivers and lakes exceed the self-purification capacity, and further algae grows excessively, breeds and even blooms. Eutrophication causes changes in water transparency and dissolved oxygen, which causes deterioration in water quality of rivers and lakes, and further causes obstruction and destruction of river and lake ecosystems and water functions.
The traditional physical, chemical and biochemical methods for treating the polluted water bodies in rivers and lakes have the problems of huge investment, difficult operation, low treatment efficiency, easy generation of secondary pollution and the like, the control of the exogenous pollution of the water bodies by using plants is always a hotspot of domestic and foreign researches, and the ecological floating island technology is one of the hotspots of the researches. The ecological floating island technology is utilized to achieve the ecological restoration effect in the treatment of river and lake pollution. The ecological floating island technology is characterized in that emergent aquatic plants are cultivated on the water surface of a natural water area by utilizing a carrier according to the self rule of the nature, the nutrition of soil is not needed, and pollutants such as TN (total nutrient) and TP (total nutrient) in the water body are removed by utilizing the effects of absorption and adsorption of nutrient-rich salt substances in the water by plant root systems, degradation of the nutrient-rich salt substances by microorganisms and the like, so that the purposes of purifying the water quality, creating a landscape effect and even harvesting the yield are achieved.
With respect to the related art in the above, the inventors consider that there are the following drawbacks: the existing ecological floating island comprises a frame body floating in a water body and groups of green plants inserted in the frame body, wherein root systems of the groups of green plants continuously grow underwater; in natural waters in rural areas, due to the fact that precipitation seasons are not uniformly distributed, the root systems of green plants continuously grow into the riverbed in a dry water period, and the root systems form an anchoring effect on the frame body in the riverway; when the ecological floating island enters a rainy season, the water level on the river channel is continuously raised, the frame body floating in the river channel is stretched by the green plant root systems of all the groups, the frame body is submerged, branches and leaves of all the groups of green plants are submerged, and the submerged green plants are easy to rot due to oxygen and illumination in water, so that the service life of the ecological floating island is shortened, and an improved space exists.
