Abstract

The invention discloses a layer disintegrating type circulating aeration technology belonging to the field of environmental protection. A layer disintegrating aerator collects over-saturation dissolved oxygen on the surface and water body with higher temperature, the over-saturation dissolved oxygen and the water body are transported into an oxygen-poor low-temperature water body in a soil layer, and an upper water body and a lower water body are exchanged, so that the natural layering of the water body is broken, the layer disintegration of the water body is realized, further the dissolved oxygen of the whole water body is in the higher level, the dissolved oxygen content in the water of soil layer is increased, the natural layering of the water body is eliminated, the activation of microorganism groups at the bottom of the water body can be enhanced, and the self-cleaning capability of the water body can be strengthened. In the invention, the dissolved oxygen content in the water body can be increased by the layer disintegrating technology, the self-cleaning capability of the water body can be improved obviously, and various pollution indexes of the water body can be improved obviously.

Description

Separate laminar cyclic aeration technology

Technical field

The present invention relates to a kind of green technology, relate in particular to a kind of laminar cyclic aeration technology of separating, be specially adapted to lake, reservoir, Landscape River, park water etc. mobile relatively poor, water body is darker, easy stratified water body.

Background technology

As shown in Figure 1, traditional water body oxygenation notion all is by inject air or pure oxygen in water body, make oxygen contact and be transferred in the water body with water body, realize the purpose of oxygenation, and in the actual nature a kind of phenomenon is arranged is exactly that the water body top layer all contacts with atmosphere, surface water is in state of saturation always, especially at high temperature season, the algae of water surface carries out strong photosynthesis and discharges a large amount of oxygen and make the water body surface water be in the over-saturation state, the dissolved oxygen that in time is not diffused into the bottom directly overflows the water surface, is diffused in the atmosphere and goes.

As shown in Figure 2, mobile relatively poor easy again stratified water body such as lake, reservoir, increase along with the depth of water 1, dissolved oxygen concentration 2 in the water progressively reduces, lakebed exhaust gas concentration 3 increases, whole water body can be divided into natural reaeration 6, aerobic district 7, oxygen balance district 8, anaerobic zone 9, mud layer V according to the difference of the depth of water, and water surface can be passed through wind-force reoxygenation 4 and photosynthesis 5 automatic reoxygenations; For the lake, the poor easy again layering water body of flowabilities such as reservoir carries out oxygenation, general all improve dissolved oxygen in the water body by mechanical aeration oxygenation way or blast aeration oxygenation way, make the organism in the aerobic microbiological decomposition digestion water in the water body, thereby excessive multiplication such as algae and degraded all contaminations in the control water body, but these aeration process need large-scale aerator, has the energy consumption height, equipment is installed inconvenience, problems such as power supply difficulty, mass transfer process when contacting with water body because of air or oxygen again can not make the oxygen that contacts with water be absorbed fully, the utilization ratio reality of oxygen only has about 15%, and this has caused the significant wastage of the energy.

Summary of the invention

In order to solve deficiency and the defective that exists in the existing aeration process, the invention provides a kind of novel, less energy-consumption, separate laminar cyclic aeration technology efficiently, utilization is separated layer principle water body top layer heavy-oxygen-enriched water is squeezed into the mud layer anoxic water, the natural layering of water body is broken in the upper and lower circulation of realization water body, with the most natural mode oxygenation in water.

Design of the present invention: it is very high that the water body of eutrophication has a top layer COD, the characteristics that BOD is very low again, the algae activity is extremely strong, the top layer algae-containing water is moved by wind, and under photosynthesis, make super-saturated dissolved oxygen, become very thin dissolved oxygen over-saturation laminar flow, and the ability of natural reaeration exists always under the effect of wind-force, collect water body epidermis heavy-oxygen-enriched water by specific equipment, it is delivered in the cryogenic water body of mud layer anoxic again, make, following water body exchange, break the natural layering of water body, the realization water body is separated layer, makes the dissolved oxygen of whole water body all be in a higher level, and the self-purification capacity of water body is improved.

Based on above-mentioned design, the present invention adopts and separates the laminar aerator, it partly is made of special-purpose floating drum, aeration power plant module, Water collecting tube, guide shell, rectified diffusion device, waterproof junction box etc., can directly collect and be transported to oxygen enrichment epidermis water in the oxygen-starved area of water body mud layer, the water body of oxygen-starved area moves up owing to being squeezed, realize two kinds of effects of oxygenation and round-robin thus, break the phenomenon of water body natural layering, the realization water body is separated layer.

Described aeration power plant module mainly adopts the water pump of low lift high flow capacity that power is provided, and simultaneously in order to increase the dynamic efficiency of aeration, separates the laminar aerator simultaneously and also can select for use wind energy to drive and corollary apparatus.

The present invention breaks the phenomenon of water body natural layering, make water body separate layer, realization is with " oxygen " oxygenation, reach the purpose of water bottom oxygen-starved area oxygenation, concrete grammar is: the effect of natural wind wind-force reoxygenation exists always, make surface water the superiors epidermis water be in the high-solubility oxygen district, be rich in algae by the surface water collection mouthful collection water body top layer that Water collecting tube is provided with above, the super-saturated water body of dissolved oxygen is forced by the aeration power plant module, utilize the powerful rotary thrust of aeration power plant module then, to be transferred to bottom hypolimnion low temperature low dissolved axygen district with the rectified diffusion device in its guide shell, and diffusion rapidly, thereby reach purpose to water body oxygenation, make bottom water and surface water replace and circulate, make no longer anoxic of the bottom, reduced the deposition of mud layer pollutent, simultaneously in bottom low temperature and the more weak zone of light, algal grown is suppressed, thereby also has the effect of certain control algae.

The mode that the present invention breaks traditions with gas oxygenation, utilization is separated layer principle water body top layer heavy-oxygen-enriched water is squeezed into the mud layer anoxic water, the natural layering of water body is broken in the circulation up and down of realization water body, with the oxygenation in water of the most natural mode, be specially adapted to lake, reservoir, Landscape River, park water etc. mobile relatively poor, water body is darker, easy stratified water body.
