Problems solved by technology

[0006] However, in the actual application of ecological floating beds, there are also some problems: First, we know that the roots of floating bed plants have limited absorption capacity, and the microbial biomass and species on the roots of floating bed plants are also limited. For heavily polluted water bodies, this traditional The treatment effect of the floating bed process is limited
Although the treatment effect of the floating bed technology at this stage is good, it takes a long time and it is difficult to meet some treatment projects with high timeliness requirements.

Abstract

The invention relates to a carbon fiber wetland type ecological floating bed and an arrangement method thereof, belonging to the field of sewage treatment. The carbon fiber wetland type ecological floating bed comprises a bed body, a biological carbon fiber material, floating bed plants and a wetland tank, wherein the wetland tank is arranged in the bed body; the interior of the wetland tank is filled with a porous light-weight artificial wetland filler; the floating bed plants are planted in the middle of the filler; and the biological carbon fiber material is hung on a suspension rod at the bottom of the wetland tank. According to the carbon fiber wetland type ecological floating bed, the processes of the ecological floating bed, bio-contact oxidation and the artificial wetland are reasonably combined to ensure that sewage is firstly subjected to bio-contact oxidation to degrade most pollutants, then the sewage is intercepted and further degraded through the wetland structure, and finally, through the absorption effect of plant roots, the quality of the sewage is better improve; and meanwhile, the reasonable layout of plants can be used for achieving the purposes of beautifying the environment, improving the ecological diversity and promoting the degradation effect on the pollutants of the whole floating bed system.

Description

technical field [0001] The invention relates to a carbon fiber wetland type ecological floating bed and a setting method thereof, belonging to the field of sewage treatment. Background technique [0002] Ecological floating bed technology is the application of soilless cultivation technology to transplant aquatic plants or improved and domesticated terrestrial plants to carriers made of bamboo, polystyrene foam board and other materials that float on the water surface and can bear a large weight. The technology that the strong root system of the plant penetrates into the water absorbs, absorbs, and intercepts nutrients such as nitrogen and phosphorus in the water body. At the same time, the microorganisms attached to the plant root system degrade the pollutants in the water body, and remove them from the water body in the form of harvested plants, so as to achieve purification. The purpose of water quality is a proven technique for in situ ecological restoration. [0003] I...
