Modularized artificial floating island for multi-medium reinforced repair of polluted water body and application of modularized artificial floating island

Abstract

The invention relates to a modularized artificial floating island for multi-medium reinforced repair of a polluted water body and application of the modularized artificial floating island. The modularized artificial floating island comprises one or more transparent floating island frames which are sequentially communicated. Each floating island frame is internally provided with a supporting mesh plate for dividing the floating island frame into an upper layer frame body and a lower layer frame body. Each upper layer frame body is internally and sequentially filled with a base body medium layer and a filler layer from top to bottom. Each base body medium layer is provided with a planting hole led to the corresponding filler layer. A plurality of check holes are formed in the side wall, corresponding to the corresponding filler layer, of each upper layer frame body. The bottom in each lower layer frame body is laid with a substrate. A plurality of check holes are formed in the side wall of each lower layer frame body. The check holes are provided with detachable mesh. Compared with the prior art, the modularized artificial floating island has the advantages that by adopting the light base body medium layers, establishing the filler layers easy to install and replace and suitable for microorganism adhesion, establishing a complete biological system layer and the like, manufacturing time is shortened, occupied land is reduced, long-term durability and efficient pollution removal are achieved, water quality purification and landscape functions are achieved due to modularized combination, and the effect of repairing the polluted water body is good.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to an ecological restoration technology of polluted surface water, in particular to a modular artificial floating island for multi-media intensified restoration of polluted water bodies and its application. Background technique [0002] Artificial floating islands have been widely used in sewage treatment, especially in the restoration of polluted surface water such as rivers, lakes, etc. . [0003] However, after decades of research and development, some artificial floating islands that have been built or are under construction at home and abroad have some problems and deficiencies, which are mainly reflected in: 1) the decontamination effect is not good due to the single effect of emergent plants 2) Most artificial floating islands use matrix materials such as PVC, which have limited service life, are easily damaged, and have insufficient buoyancy, which affects the stabil...

Problems solved by technology

This patent uses a relatively traditional PVC material as the main frame material. It is easy to be exposed to the sun for a long time outdoors and cause aging. At the same time, substrates such as zeolite and ceramsite are used as carriers for the growth of plants and microorganisms. The resulting bed body sinks into the water body, etc., and the hollow tube of the lower frame is planted with plants. If the pipe enters water, the settlement of the bed body will be accelerated due to the increase in weight.
