Background

The ecological floating island is also called an artificial floating bed, an ecological floating bed and the like. The artificial floating island is one of artificial floating islands, and aims at eutrophicated water quality, and degrades the content of COD, nitrogen and phosphorus in water by utilizing the principle of ecological engineering. The method takes aquatic plants as a main body, applies the technical principle of soilless culture, takes high polymer materials and the like as carriers and substrates, applies the symbiotic relationship among species, and fully utilizes the space ecological niche and the nutrition ecological niche of the water body, thereby establishing a high-efficiency artificial ecosystem for reducing the pollution load in the water body. It can greatly raise water transparency, and can effectively improve water quality index, specially has good inhibiting effect for algae. The ecological floating island has the main effect of purifying water quality by absorbing eutrophic substances, such as total phosphorus, ammonia nitrogen, organic matters and the like, in water by using the root system of plants, so that the nutrition of the water body is transferred, and the phenomena of fishy smell and eutrophication of the water body caused by the insufficient sealing or self-circulation of the water body are reduced. The existing ecological floating bed provides sufficient oxygen for plant growth through an aeration device, has high equipment cost and large quality, generally and directly aerates the bottom end of a filler, and the floating bed provides oxygen for plants and simultaneously ensures that algae pollutants attached to the filler obtain a better growth environment, thereby being beneficial to algae growth and reducing the efficiency of ecological restoration.
