Description
Technical field
It is that one kind is used for deep water type (water the invention belongs to environmental science, environmental project, discharge water science and engineering field
Deeply more than 10 meters, similarly hereinafter) lake, reservoir destruction water body seasonality structural stratification, carry out water correction and are filled with the vertical flow repaired
Oxygen mixer.
Background technology
Deep water type Hu Ku summer and autumn be bullied temperature rise influence can cause water temperature gradient Vertical Difference so that cause water
The density variation of body interlayer, so as to water column structure stabilization lamination, abbreviation thermally stratified layer occur.Thermally stratified layer hinders water body Vertical Square
Upward exchanges of mass and energy, causes that top layer water environment dissolved oxygen content is higher, pH value is raised, algae distorted proliferation, and bottom
Layer water environment promotes total phosphorus, ferrimanganic etc. in deposit to be discharged in overlying water to anoxic and anaerobic state transition, causes Hu Kushui
Body ferrimanganic concentration over-standard and eutrophication.Thermally stratified layer induces deep water type Hu Ku periodicity endogenous pollutions, causes the seasonal evil of water quality
Change, management, the operation of downstream water-purifying process and the induction system of water purification to water source Hu Ku cause certain difficulty.
Oxygenation hybrid technology in situ can effectively destroy/disturb water body layering, improve the vertical mixing intensity of reservoir, increase
Reservoir bottom dissolved oxygen concentration, the internal loading for suppressing pollutant in deposit and algae abnormality propagation, are to solve thermally stratified layer
The fundamental way of the water quality endogenous pollution of Hu Ku, is a kind of directly efficient Water quality restoration improving environment.Typical aeration in situ
The hybrid technology peripheral doses skill such as including stratospheric (air or pure oxygen) aeration, the mixing of bubble plumage, blooming cylinder mixing, mechanical mixture
Art is the water correction method of representative, and achieves more successful application.However, above-mentioned technology focus mostly on it is shallower in the depth of water
Non-layered or weak laminated devices source water, and the aspect such as feasibility in technology application, stability and economy remained not
Foot.The aeration process that pumps up water is at present more typically for the mixing oxygenation technology under the big depth of water and strong stratified environments, the technology
With the direct oxygenation of bottom water body and the upper and lower indirect oxygenation function of water layer of mixing, control endogenous pollution can be reached, suppress algae
Growth, the purpose for improving source quality.But the technology there is also the shortcoming for being difficult to overcome simultaneously, element of installation mistake is mainly manifested in
Many, composition is complicated, overall both bulk, is that in-site installation and operation management bring difficulty；Meanwhile, analyzed from operation principle,
Bottom water body is promoted to top layer and participates in mixing by the equipment by the way of gas bullet piston, is consumed energy larger, less efficient, it is contemplated that to reach
Thoroughly improve, it is necessary to reservoir is integrally thoroughly mixed, this is difficult to bear in the consumption of power to deep water lake storehouse water quality.Heat
Layering effect causes that surface water temperature is higher, dissolved oxygen is higher close to saturation, pH, and algae is enriched, and bottom water temperature compared with
Low, dissolved oxygen content is too low, pH is relatively low, so if making full use of the characteristic of surface water, lake bottom of the reservior portion is introduced into, the bottom of with
Layer water mixing, will reduce aeration energy consumption, improve aeration efficiency, suppress algal grown；Surface water is located at Hu Ku surfaces, has
Larger potential energy, as long as therefore make it possible to be introduced into lake bottom of the reservior portion by overcoming density contrast, will in terms of power consumption
More existing aeration process reduction of pumping up water；The mixed water body of oxygenation and residual exhaust density are smaller, will be moved to Hu Ku top layers
It is dynamic, hierarchy will be carried out to destroy/disturb.
The content of the invention
