Combined type high-efficiency floating island

Abstract

The invention provides a combined type high-efficiency floating island. The combined type high-efficiency floating island comprises a plant planting area, a biological filler hanging area and an aeration area which are sequentially arranged from top to bottom; the plant planting area is provided with a floating bed, the floating bed comprises a plurality of floating plates which are connected with one another, the floating plates are hollow and internally filled with filler, planting pits are formed in the centers of the floating plates, and hydrophilic plants are planted in the planting pits; the biological filler hanging area comprises a plurality of ropes, the upper ends of the ropes are connected below the floating bed, and the lower ends naturally droop; a plurality of groups of biological fillers are hung on the ropes; and the aeration area is provided with an aeration device, the aeration device comprises an aeration disc, a plurality of aeration pipes are fixed on the aeration disc, and aeration holes are formed in the aeration pipes. According to the invention, the hydraulic retention time can be prolonged without destroying microbial biofilm formation and plant rhizosphere stability, the three-dimensional space is saved, and pollutants are efficiently removed.

Description

Technical field: [0001] The present invention belongs to the technical field of water pollution control, particularly relates to a composite high efficiency floating island. Background technique: [0002] In recent years, rivers, lakes, reservoirs, ponds and other water bodies affected by environmental pollution, caused by eutrophication, destruction of the ecological balance of the water body. Currently, application of ecological pollution of water in the floating island of growing concern, the use of floating island ecological cultivation of plants on which polluted water to remove contaminants nitrogen, phosphorus, transition algae growth inhibition water, and also beautify the landscape of water, you do not need to have an area of ​​low cost and good repair effect and so on. [0003] Purification of the biofilm which rely mainly on floating island of plants the direct absorption of Nitrogen, phosphorus and other nutrients to achieve, in addition to adhering to the floating is...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional ecological floating islands mainly have the following problems: the purification effect mainly depends on the direct absorption of nutrients such as nitrogen and phosphorus in the water body by the floating island plants. In addition, the biofilm formed by the microorganisms attached to the roots of the floating island plants Can accelerate the degradation process of macromolecular pollutants in water

However, traditional ecological floating islands have problems such as low purification efficiency, long recovery period and inability to improve water hypoxia, which cannot meet the needs of water pollution control

Ordinary plant ecological floating islands are inefficient. After investigation, if ecological floating islands are used in some urban inland rivers and large submerged plants such as calamus and canna are placed, one is easy to block the river, and two is easy to attract mosquitoes in summer. secondary pollution
