Biological floating island

Abstract

The invention relates to a biological floating island which comprises a plurality of biological floating island units which are combined, wherein each biological floating island unit comprises a flexible floating basin (1), a floating bottle (2), sand (3), sludge (4), natural floating stones (5) and plants; the floating bottle is arranged in a long-strip-shaped bag (6) on the side surface of the flexible floating basin; the flexible floating basin is formed by sewing corrosion-resistant and high-strength polyester reverse filtration materials; a rigid stainless steel wire ring with a supporting effect is arranged at each of the top and bottom of the flexible floating basin; the stainless steel wire rings are wrapped and sewed by the reverse filtration materials; the sludge and the natural floating stones are arranged in the floating basin and used for adhering and fixing the root systems of the plants in the floating basin and providing biofilm formation and growth conditions for microorganisms in the floating basin. According to the biological floating island, the technologies of plant absorption and adsorption, floating island filtration and adsorption and microbial biofilm formation are integrated in the whole system to purify a water body.

Description

technical field [0001] The patent of the present invention belongs to the technical field of ecological engineering treatment of water pollution, and in particular relates to the comprehensive utilization of plant absorption and adsorption technology, floating island filtration and adsorption technology, and the integration of microbial membrane technology to realize the purification of polluted water. Background technique [0002] An artificial floating island is a floating structure with aquatic or terrestrial plants. As early as the 1950s, artificial floating island technology was used by farmers in Mexico and Myanmar to grow crops. With the rapid economic growth, it has brought heavy loads to various natural water bodies. Under the combined action of foreign substances and endogenous pollution, the nutrients in the water body are excessive, causing the excessive reproduction of phytoplankton, which leads to the deterioration of water quality and the water environment.
