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, there is ecosystem degradation because of pollution in some lakes, river, and because of water body, day by day eutrophication is even black smelly in some cities, seriously affects urban look and resident's living guarantee.This is the randomness discharge because of trade effluent and sanitary sewage on the one hand, causes the nutritive substance enrichments such as water bodies of rivers and lakes heavy metal, organic pollutant and N, P, occurs water quality severe exacerbation; Be many rivers quilts " sclerosis " or " canalization " on the other hand, destroyed artificially the biologic chain of natural river health, stream's self-purification ability is declined and even lose.Now there are some researches show: dissolved oxygen content deficiency is to cause the black smelly major cause of water body, in the time that dissolved oxygen is 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; In the time that dissolved oxygen is greater than 1mg/l, a lot of anaerobions cannot survive, and the thorough decomposing pollutant of aerobic microbiological is CO
2and H
2o, water body is purified.Because the dissolved oxygen in water body is mainly derived from the photosynthesis of air reaeration and waterplant, therefore, black and odorous river is carried out to 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.
