Description
Technical field
The invention belongs to nature clean energy technology field, particularly relate to the oxygen enrichment nanometer matrix complex ecological floating bed of a kind of wind and optically-coupled.
Background technology
In the last few years, ecosystem degradation occured because of pollution in some lakes, river, and the city that has seriously affects urban look and resident's living guarantee because of water body eutrophication even black smelly day by day.This is the randomness discharging because of trade effluent and sanitary sewage on the one hand, causes water bodies of rivers and lakes heavy metal, organic pollutant and the nutritive substance enrichments such as N, P, the water quality severe exacerbation occurs; Be many rivers quilts " sclerosis " or " canalization " on the other hand, destroyed artificially the biologic chain of natural river health, so that the stream's self-purification ability descends even forfeiture.Existing studies show that: the dissolved oxygen content deficiency is to cause water body to deceive smelly major cause, when dissolved oxygen during less than 1mg/l, anaerobion amount reproduction, because of its thoroughly decomposing pollutant produce H
2S, (NH
4)
2S, CH
4Deng toxic substance, cause water body black smelly; When dissolved oxygen during greater than 1mg/l, a lot of anaerobions can't survive, and the thorough decomposing pollutant of aerobic microbiological is CO
2And H
2O, water body is purified.Because the dissolved oxygen in the water body is mainly derived from the photosynthesis of air reaeration and waterplant, therefore, black and odorous river is carried out artificial aeration's oxygen enrichment and illumination compensation, and then suppress anaerobion and grow, promote growth of aerobic microorganisms, can effectively remove water pollutant, purify water, improve or alleviate the black smelly phenomenon of water body.
At present restoration of the ecosystem is the major measure of safeguarding lake, river health, wherein biological floating bed because it has good purification, can improve species diversity, the advantages such as operational management is relatively easy, cheap, non-secondary pollution, become common technology in the polluted water body restoration of the ecosystem of lake, present river.That Chinese patent application 200910026735 has proposed is a kind of " purification of water quality combined biological floating bed ", Chinese patent application 201010285641 has proposed a kind of " matrix-plant coupling connected type flowing water floating bed ", these schemes belong to and adopt waterplant and matrix fill to combine to process the method for river wastewater, the more common plant floating bed larger improvement that has for the treatment of effect, but fail to solve the low problem of dissolved oxygen content in the water body, so that microorganism is slower for hypoxgia, degradation speed on the filler, it is poor effect still; Chinese patent application 200820156779.6 has proposed a kind of " wind driving underwater aerator ", Chinese patent application 201110283034.2 has proposed a kind of " solar-energy ecological set composite ", these schemes are to utilize wind energy or sun power to water body aeration oxygen enrichment, the propulsion source off-set facility such as store battery or generator need be equipped with but, these off-set facility not only cost are high, and have also can cause secondary pollution; Chinese patent application 200710031242.7 has proposed " a kind of energy source self-help river water contamination treating apparatus ", this scheme adopts the mechanically operated mode water of harnessing a river to pollute, though it has saved the facilities such as power supply, generator or store battery, but because blocking of floating bed bed body weakened the water body intensity of illumination, benthos can not normal growth because illumination is not enough, causes the reduction of species diversity.
How to overcome the deficiencies in the prior art and become one of emphasis difficult problem that needs to be resolved hurrily in the current natural clean energy technology field.
Summary of the invention
The oxygen enrichment nanometer matrix complex ecological floating bed that the object of the invention is to overcome the deficiencies in the prior art and a kind of wind and optically-coupled are provided, the present invention not only has organic pollutant in the effective removal unhurried current water body and the advantage of nutritive salt, and have good looking appearance, simple in structure and economical and practical advantage, be applicable to city get dirty improvement and the reparation of the common water bodys such as lake, river.
