Background technology

In recent years, body eutrophication problem has been subject to whole world water surrounding domain expert's extensive concern.China's immediate offshore area and most of river course, lake ecological environment worsen, mankind's activity reduces even aquatic macrophyte to the aggravation of ecosystem impact to disappear gradually, and recovering large-scale aquatic vegetation becomes one of main contents that nutrition enriched shallow water ecology repairs.

Submerged vegetation can effectively be repaired by absorbed nitrogen, phosphorus and the reply eutrophication water that gram comes into force.Photosynthesis is the most important Metabolic activity of submerged plant, and the photosynthesis of submerged plant is subject to the restriction of low light photograph conventionally.Due to the impact of water body solute, suspended particle and the depth of water, solar luminous energy is decayed rapidly, and in the loss (10% left and right) of air and water intersection, the phenomenon of illumination deficiency the most easily occurs in water body in addition.It is generally acknowledged, the not enough incident light of water-bed light intensity 1% time, submerged plant just can not be settled down.The Photosynthetic Characteristics such as the photosynthetic light compensation point of submerged plant, have determined full depth and photosynthetic yield and competitive capacity that submerged plant can distribute under water.

Because whole plant materials is immersed in water completely, be subject to coercing of the Water Factors such as transparency, substrate, stormy waves the most obvious.Polluted-water transparency is low, and Underwater Optical is according to not enough, and submerged plant cannot obtain enough luminous energy.When running into the disaster of unexpected generation, as causing water level, flood, morning and evening tides etc. raises, and submerged plant is often because of can not get sufficient illumination, can not carry out normal photosynthetic and respiration and death gradually, and finally cause the exhaustion of submerged vegetation group.Therefore,, although the example that aquatic vegetation recovers is a lot, group's system of restore vegetation is often difficult to stable survival.China also there is no one and has realized the case that the ecosystem recovers completely at present.How to recover submerged plant, how to make newly-built Population adaptation environmental change and environmental disaster, and progressively tend towards stability, this is the key that submerged vegetation recovers.

Existing floating bed technology is to utilize the waterplant of planting on the water surface floatable bed body and bed body, by the root system filtration of plant and the pollution substance in absorption sewage, this technology is obvious to the decontamination effect improving of eutrophication water quality, but the plant in floating bed only limits to emergent and the floatingleaved plant that can surface, and has ignored the cleaning action of submerged plant in water body.There is investigator to propose the concept of Liftable type floating bed, the denomination of invention that is (CN201031181Y) as publication number is " biological sewage treatment liftable artificial plant floating bed and making method and using method ", introduced a kind of liftable artificial plant floating bed of middle micro polluted source as processing object of take, but this technology is mainly used in solving the problem that floating bed cannot be survived the winter, there is no and consider the low restriction to submerged plant growth of transparency.Also have investigator to propose gradually heavy formula mattress technology, and difference is hung to the degree of depth and done transplanting experiment, but the shortcoming of the method is cannot realize piling in the darker waters of the depth of water.
