Integrated floating island bio-bed for repairing black and odorous water body

Abstract

The invention discloses an integrated floating island bio-bed for repairing a black and odorous water body. The bio-bed comprises a floating island arranged above the water surface and a bio-bed arranged below the water surface. The floating island is fixedly connected with the bio-bed; aquatic plants are planted on the floating island; biological ropes sinking into the water body are suspended around the floating island; the bio-bed comprises a diffusion part and a filler part which are arranged up and down; the diffusion part and the filler part are separated through a partition plate; a plurality of meshes are formed in the partition plate; a filler capable of being attached with microorganisms is filled in the filler part; an aerator pipe is installed in the filler part; mesh-shaped open holes are formed in the periphery of the bio-bed; filter cloth covers the periphery of the filler part; and the microorganisms attached to the surface of the filler are diffused into the water bodythrough the diffusion part. By adopting the integrated floating island bio-bed for repairing the black and odorous water body, ammonia nitrogen, CODcr and nitrate nitrogen in the black and odorous water body can be effectively removed; and meanwhile, the integrated floating island bio-bed also has the effects of deodorizing, removing black color and inhibiting algae.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an integrated floating island biological bed for repairing black and odorous water bodies. Background technique [0002] Ecological floating island is an in-situ water ecological restoration technology developed in recent years. The ecological floating island uses plant roots to absorb eutrophication substances in the water body to reduce nitrogen, phosphorus and organic matter in the water body. The ecological floating island has the effect of beautifying the landscape while achieving the effect of water purification. At the same time, it is low in cost, convenient in operation and maintenance, and does not produce secondary pollution. [0003] Traditional ecological floating islands only use floating island plants to purify the water body, often due to the limitation of the amount of plants, the removal effect of nitrogen, phosphorus, organic matter, etc. is not good, especiall...

Problems solved by technology

[0003] Traditional ecological floating islands only use floating island plants to purify the water body, often due to the limitation of the amount of plants, the removal effect of nitrogen, phosphorus, organic matter, etc. is not good, especially for black and odorous water bodies, the removal effect of floating island plants is limited, it is difficult to achieve the desired effect
