Description
Technical field
The utility model is related to environmental technology field, specifically a kind of unpowered solar energy promotes Dissolved Oxygen in Water to answer
The device of oxygen.
Background technology
Contemporary China getting worse, with rapid economic development, the water pollution problems such as urban river, lake
It is more serious, wherein, pollution and the body eutrophication of quality of water environment become the main problem of water pollution；
Body eutrophication refer to the nutrient concentrations such as Water (N), phosphorus (P) it is excessive caused by water pollution show
As, it is unbalance so as to cause aquatic ecosystem species distribution its essence is the input and output disequilibrium due to nutritive salt, it is single
Species overgrow, and destroy the flowing of the substance and energy of system, make entire aquatic ecosystem disequilibrium, and gradually trend is gone out
It dies, under field conditions (factors), lake can also be transitioned into eutrophic state from lean nutritional status, but this natural process is very slow
Slowly, and the body eutrophication caused by industrial wastewater and sanitary sewage of the anthropogenic discharge containing nutriment then can be in the short time
Interior appearance leads to planktonic algae amount reproduction in water body, is decomposed after algae and other planktonic organism death by aerobe, no
Dissolved oxygen in disconnected consumption water, causes dissolved oxygen in water body to reduce, water degradation causes a series of water environment pollution problems；
Mainly two kinds of dynamic type and Engineering-type, power type are aerated skill to domestic and international general water reoxygenation method at present
Art, aeration is that the oxygen in air is forced the process shifted into liquid, the purpose is to obtain enough dissolved oxygens, in addition, exposing
Gas, which also has, prevents suspended substance in pond from sinking, and strengthens the purpose that organic matter is contacted with microorganism and dissolved oxygen in pond, so as to ensure pond
Interior microorganism to the oxygenolysis of dirty Organic substance in water, that is, passes through the suction of aeration pump under conditions of having sufficient dissolved oxygen
Entrance sucks gas using suction function, and high-speed rotating impeller of pump stirs liquid and gas mixing, due to the pressurization in pump
Mixing, gas are fully dissolved with liquid, and the method is although efficient, with obvious effects, but operating cost is higher, more difficult after damage to repair
Multiple, energy consumption is high, and noise is big；
Engineering-type uses various forms of hydraulic structures, water and soil building overfull dam surface to add, and rough, catalytic oxidation is permeable
The hydraulic methods such as dykes and dams, drop water aeration oxygenation, dykes and dams are built or be transformed to requirement manually to the method mostly, and not only quantities is huge
Greatly, it is difficult to realize, and serious forgiveness is low, repairs difficult in the short time.Dykes and dams, which are transformed, needs huge fund input, and improved
Dykes and dams also have ecological environment the influence for being difficult to estimate；
When one source of the Dissolved Oxygen in Water of nature is oxygen in water unsaturation, the oxygen in air is through water body table
Face is gradually dissolved from gas-liquid exchange process to water body inside and is spread and penetrate into；It is photosynthetic that another source is that aquatic plant passes through
The oxygen released is acted on, nature water body has the inner cyclic process of more rule, i.e., under sunlight, as water temperature increases
Add, the aggravation of local water surface evaporation process (between such as daytime under solar irradiation, bank soil has lower specific heat capacity than water body,
It can heat up faster under similary radiation parameter；It is for another example lower by the water surface water surface surface temperature more naked than periphery of emergent aquactic plant masking
Deng), the evapotranspiration constantly into air of healed water body, due to the upward evapotranspiration of vapor, and the slightly higher water body density of temperature is more
Small, multifactor common driving surface water constantly moves upwards, middle level and bottom lower temperature (acquisition shines upon less)
Not heating water body can constantly supplement upwards, form local upper up-flow, meanwhile, the slightly cold water body of local water surface sinks, shape
Into sinking, flowed so as to form the microcirculation of rule inside water body, the micro-circulation processes inside this surface water body increase
The contact probability of water body and air is added, and superficial dissolution oxygen is carried into mass transfer to bottom water body, so as to promote Dissolved Oxygen in Water
Recovery process；
Since in contaminated water body, plankton growth is vigorous, consumes the dissolved oxygen of water body, it is transparent to reduce water body
Degree hinders the radiation response of sunlight, limits dissolved oxygen transmission, and underwater microcirculation is weaker compared with normal water body；
If solar radiant energy can preferably be used so that this portion of energy can more make full use of promotion
In water body inner cyclic process, this clean energy resource of solar energy just can be more effectively utilized, it is more effective that Dissolved Oxygen in Water is promoted to pass
The shortcomings that matter and recovery process, this method can effectively overcome traditional reoxygenation method highly energy-consuming, and luminous energy is a kind of clear in itself
The clean energy without secondary pollution, will not adversely affect periphery ecology, be a kind of sustainable environmental-friendly efficient
The energy, it is for manager and a kind of motorless, it is low to take efficient scheme.
