Description

Mulberry floating island for treating water eutrophication
Technical Field
The invention relates to the technical field of water purification, in particular to an ecological floating island device.
Background
With the rapid development of society, the rapid population increase and the industrial development cause the pollution of rivers and lakes in different degrees, and a large amount of nutrient substances such as nitrogen, phosphorus and the like required by organisms are discharged into a water body, so that the phenomena of rapid propagation of algae and other plankton, reduction of dissolved oxygen of the water body, deterioration of water quality and mass death of fishes and other organisms, namely the eutrophication phenomenon of the water body, are caused. In recent years, China pays attention to the protection of water environment. In particular, in water areas where there is no vitality, artificial aids are required. The ecological floating island aims at eutrophic water, uses plants as main bodies, establishes a high-efficiency artificial ecological system, and can play a role in degrading COD (chemical oxygen demand), nitrogen and phosphorus contents in water, weakening water pollution load and improving water quality. The existing ecological floating island has some defects: (1) the purification mode is single, and the effect is relatively poor, and current artificial floating island generally only plants aquatic plant on the floating island, only relies on the absorption of plant, but the plant absorptive capacity is limited, and purifying effect is poor, and is efficient. (2) Is easily influenced by water environment, plants naturally grow in eutrophic water, the survival rate is not high, and the plants are easy to die due to oxygen deficiency, thereby influencing the purification effect of the floating island.

The device is simplified into a yarn package fixed on the main trunk of the mulberry, granular water-absorbing sponge is wrapped in the yarn package, the diameter of the water-absorbing sponge is 3-10cm (gaps of the granular sponge are used for air flowing and providing oxygen), the water-absorbing sponge wraps the root, the root system is not arranged at the bottom of the yarn package, and the water-absorbing sponge at the bottom of the yarn package is in contact with a water body so as to continuously supply water and nutrients in the water body. The yarn package outside the mulberry can sink the water, and the micro-nano bubble device is relied on to provide oxygen.
The invention fully utilizes the advantages of the micro-nano bubbles and the mulberry and can effectively treat the water eutrophication. Has the advantages that: at present, most of ecological floating islands adopt aquatic plants, and water eutrophication is treated by the aquatic plants. The method adopts a mode of combining the micro-nano bubbles and the mulberry trees, and can effectively and quickly solve the problem of water eutrophication. The mulberry has strong capability of absorbing nitrogen and phosphorus, also has ecological functions of enriching heavy metal elements and the like, can adapt to the environment in a water body due to waterlogging tolerance, and can kill a part of algae due to allelopathy of the mulberry to the algae; the good characteristics of the micro-nano bubbles enable the micro-nano bubbles to form a relatively stable gas-liquid two-phase space at the root of the mulberry to meet the conditions required by the survival of the mulberry, and besides oxygen is provided for the mulberry, the micro-nano bubbles can also aerate anoxic eutrophic water to slow down the death phenomenon of organisms such as fishes and shrimps due to oxygen deficiency, and can also provide the activity of aerobic microorganisms in the water to accelerate the decomposition of dead animals and plants, thereby promoting ecological cycle. The solar energy is used for providing energy, the solar energy is clean and environment-friendly, and basically no cost is generated in the operation process; nitrogen and phosphorus causing eutrophication of the water body are taken as nutrients and transferred into the mulberry and the mulberry leaves, so that the wastes are recycled and certain economic benefits can be generated; the floating mulberry floating island can provide a habitat for birds and fishes, and is an environment-friendly artificial floating island; the micro-nano bubble emitting device can freely rotate so as to freely float on the water surface, and manual maintenance is not needed. The invention has the main significance that aiming at large-area lakes with eutrophication, the combined application of a plurality of mulberry floating islands can quickly and efficiently solve the problem of water eutrophication, promote the ecological cycle of the lakes and purify the ecological environment, and lead black and odorous water to be recovered to green water and green mountains.
