Aeration treatment floating bed for draining and raising deep water body

Abstract

The invention provides an aeration treatment floating bed for draining and raising deep water body by combining techniques of a diesel engine or a motor, an air compressor, a drainage aerator, a biological anti-pollution filter material, a bacteria drug cabin and a floating bed. The aeration treatment floating bed uses a pontoon combination as a floating support and the diesel engine or the motor as a power source to generate compressed air which is conveyed to a gapped aerator combiner of which the upper part and the lower part are provided with pipelines or ditches; a drainage pipe frame, a flow guidance pipeline (frame) or a ditch arranged on the lower part selectively guides deep sewage to raise upwards, and the pipeline or the ditch on the upper part guides the flow upwards directionally; and a microorganism preparation and a correlative medicament are added close to a sewage level surface to sufficiently purify oxygenrich sewage. A place close to the sewage level surface above the sewage level surface is provided with a biological filter material and a plant root system support to further treat pollutants in water. The aeration treatment floating bed has the characteristics of simple structure, simple and convenient mounting, strong movability, long service life, high purification efficiency, notable energy saving effect, low cost and the like.

Description

(1) Technical field [0001] The invention relates to a sewage purification and oxygenation device, in particular to a floating bed type aeration treatment floating bed device for drainage and lifting of deep water bodies, which belongs to the field of environmental protection sewage purification and oxygenation, and can be used for lifting and oxygenation of the bottom water body of aquaculture. (2) Background technology [0002] At present, many natural water bodies such as lakes, reservoirs, and rivers in our country are mostly eutrophication, black and odorous, and the pollution of rivers near cities and towns is particularly serious. In some natural water bodies, the water body has little flow and is basically in a static state. As the water depth increases, the DO value gradually decreases, and the DO value at the bottom basically drops to zero. The bottom water body is in a state of severe anoxic state, and a large amount of organic pollution accumulates to form sedimen...

AI Technical Summary

Problems solved by technology

Due to the limitations of natural water bodies such as wide area, large area, complex terrain, lack of power facilities or inconvenient use, coupled with the high operating costs of traditional water treatment, the development of water quality management has been restricted to a large extent.

After searching the patent literature, it was found: 94108064.1, the name is: floating bed filter. Although this floating bed filter can achieve deep filtration, high operating flow rate, low resistance, and has the ability to intercept pollutants, it cannot directly oxygenate the water body. aeration

01142692.6, the name is: floating bed sewage purification device, which can directly aerate the water body with oxygen, and can further treat the sewage by combining the filter material of the biological carrier and the underwater lighting lamp, but it cannot selectively supplement the oxygen to the deep sewage , and cannot adjust the depth range of water treatment according to the depth of the water environment, and is easily restricted by various complex environmental conditions of natural sewage water bodies
