Multifunctional combined ecological floating bed

Abstract

The invention discloses a multifunctional combined ecological floating bed which comprises a floating bed body defined by PVC plastic pipes. The bed body is divided into aquatic plant planting areas and light-catalyzed reaction areas through PVC plastic pipes, fishing nets are arranged at the bottoms of the aquatic plant planting areas, and the light-catalyzed reaction areas are formed by corrugated plates embedded into the PVC plastic pipes. Photocatalytic materials are fixed to the corrugated plates, and a biological reaction area where combined filler is hung is arranged on the lower portion of the bed body. Upper-layer aquatic plants of the multifunctional combined ecological floating bed can absorb nitrogen and phosphorus in water, the lower-layer combined filler can degrade organic matter in the water into inorganic matter by enriching microorganisms, a photocatalyst can oxidize organic pollutants and inorganic pollutants hard to degrade biologically in the water under natural light, and therefore all the reaction areas of the multifunctional combined ecological floating bed are organically combined to remove multiple pollutants in the water.

Description

technical field [0001] The invention relates to a multifunctional combined ecological floating bed, which belongs to the technical field of water treatment. Background technique [0002] There are a variety of pollutants in natural water bodies, mainly including: conventional organic pollutants that are difficult to biodegrade, such as COD remaining in the tail water of urban sewage treatment plants; rural non-point source pollution brought into the water body through runoff pesticides, herbicides and other persistent Organic pollutants; nitrogen, phosphorus and other pollutants that can easily cause eutrophication of water bodies, etc. [0003] At present, the commonly used water treatment methods mainly include physical methods, including precipitation, flotation, filtration and reverse osmosis, etc.; chemical methods, mainly including neutralization, coagulation, redox, ion exchange and electrodialysis, etc.; biochemical methods, mainly including Activated sludge method ...

AI Technical Summary

Problems solved by technology

The biochemical method is convenient to operate and manage, but because the organic matter in the wastewater is highly toxic, difficult to degrade, and has poor biodegradability, directly entering the biochemical system will cause a great impact on microorganisms and seriously inhibit the growth of microorganisms

The effect of a single technology is not very ideal, so it is necessary to develop and adopt new treatment technologies and processes, such as the method of combining multiple water treatment technologies
