Description
Technical field
The present invention relates to the technology for inhibiting algae growth, more particularly to a kind of L-type ultraviolet irradiation algal-inhibition devices.
Background technology
The production and life of the mankind will produce the largely nutriments such as nitrogenous, phosphorous, they enter the water such as lake, reservoir
Body can cause the quick breeding of algae and phytoplankton, lead to fish in water body, shellfish and other aquatile mortalities, aquatic
Bio-diversity and stability reduce, and lead to water quality deterioration, and then cause the eutrophication of water body.The trunk river in China, such as
The Changjiang river, the Yellow River, the Zhujiang River, Song Hua River etc. and some large-size lakes, such as Taihu Lake, Poyang Lake, Chaohu, East Lake and Dian Chi occur
It crosses algae reproduction and breaks out wawter bloom phenomenon.The generation of wawter bloom can bring serious water pollution, the wawter bloom of outburst that can lead to water body
Anoxic leads to the aquatiles death by suffocation such as fish, shrimp, shellfish；Wawter bloom can generate algae superposed layer on water body surface layer, cause water body saturating
Lightness reduces.It also will produce the various secondary metabolites for having peculiar smell in algae growth course, which can emit bad smell so that
Water body is smelt as of rotten fish unpleasant；It is noxious material, such as alkaloid, polypeptide and lipopolysaccharides three that generated secondary metabolite, which has some,
Class, to the toxic effect of aquatile, aquatic bird, domestic animal and the mankind.The wawter bloom of generation can also aggravate Drinking Water and work
The processing cost of industry water.
There are the methods of biology, chemistry and physics to the inhibition of algae and inactivation treatment at present.Common physical method had
Filtering method adds clay, ultrasonic wave and ultraviolet irradiation technology etc..Ultraviolet irradiation technology is that the energy generated by ultraviolet light is led
It causes organic substance in frond to burn or make a variation, achievees the effect that algae, this method is inhibited to be widely used to sewage and drinking water
Disinfection, but for inhibit wawter bloom algal grown and prevent wawter bloom occur correlative study and put into practice it is still immature, mainly have with
Under several aspects the shortcomings that：
(1) suspended matter inhibits algae growth to have larger impact ultraviolet irradiation in algae solution turbidity and water, reduces the suppression of ultraviolet lamp
Algae effect.
(2) when long-play uv light irradiation, ultraviolet lampshade is easy fouling, and frond is easy sedimentation and is attached on lampshade,
Influence ultraviolet light appear and effect of algae restraint.
(3) conventional static ultraviolet irradiation algal-inhibition device, when providing lasting irradiation operation, algae is easy flocking settling,
It is deposited on ultraviolet lampshade, and due to lacking flowing mixing, leads to the light irradiation dark space far from ultraviolet lamp, algae inactivating efficacy
Difference, and away from the closer algae of ultraviolet lamp because the irradiation being subject to is too strong, cell can rupture, and cell inclusion, which leaks, generates secondary pollution,
It is unfavorable for the uniform inhibition and inactivation to algae.
Above-mentioned disadvantage reduces inhibition treatment effect of the ultraviolet irradiation technology to algae, is unfavorable for before wawter bloom occurs,
Inhibition to Bloom-causing Algal is also unfavorable for the prevention in advance to wawter bloom to a certain extent.
Invention content
The technical problem to be solved by the invention is to provide a kind of based on ultraviolet irradiation, portable, laboratory and open air
The L-type ultraviolet irradiation algal-inhibition device used can achieve the purpose that prevent wawter bloom by the growth of inhibition Bloom-causing Algal.
The main technical schemes of the present invention are as follows：
A kind of L-type ultraviolet irradiation algal-inhibition device, including shell, ultraviolet lamp component, magnetic-type cleaning assembly, inlet, go out
Liquid mouth and leakage hole；The ultraviolet lamp component is mounted on the medium position in the shell, institute along the length direction of the shell
It states magnetic-type cleaning assembly and is set in the ultraviolet lamp component external；The inlet is arranged in the first end end of the shell
Medium position, the liquid outlet is positioned close to the shell of the second end end opposite with the first end of the shell
On body, on the housing, the inlet is connected to the liquid outlet for leakage hole setting, liquid from the inlet into
Enter the length direction for flowing through the shell and flowed out from the liquid outlet, forms the liquid stream flow direction of L-type in the shell.
Beneficial effects of the present invention include：
The present invention irradiates that algae is inhibited to grow by built-in ultraviolet lamp component, is a kind of static and dynamic radioaction processing knot
The processing mode of conjunction, can remove in real time at runtime Transparent lamp shade outer wall attachment algae, ensure ultraviolet light appear with it is good
Effect of algae restraint, the algae caused by algae solution mixing is uneven inactivates uneven when can avoid continuous operation, and the present invention can be transported continuously for a long time
Row is realized and inhibits algae growth.Specifically：
1, feed liquor direction is along the axial direction of Transparent lamp shade (or shell), and algae solution in shell is along Transparent lamp shade (or shell
Body) axial direction on Uniform Flow, and go out from liquid outlet, form L-type flow direction in shell, algae can be inactivated to greatest extent
Inhibit.Further, under the driving of the liquid stream of the L-type inflow and outflow of design, by pump it is given in low discharge (1500ml/min~
When 3500ml/min), microalgae particle can be uniformly distributed in the device, suffered irradiation dose can with median dose (10~
15mWs·cm-2) based on, it can avoid burning and puncturing algae wall, intracellular fluid caused to leak.
2, simple and fast to the cleaning of the Transparent lamp shade in device, cleaning process is not required to stripping device, when device is run,
The cleaning that built-in Transparent lamp shade can be completed by external control ensures that ultraviolet light is good and appears and effect of algae restraint.
3, the connection between inlet and liquid outlet realizes the interior cycle of algae solution in shell, realizes the dynamic to algae solution
Inactivation treatment, the algae close apart from ultraviolet lamp caused by can preventing algae when traditional stewing process from settling are burnt thin more by irradiated
The problem of cell wall, by controlling algae solution rate of circulating flow in the device and residence time, it can be achieved that algae rapidly and efficiently inactivates.

~1.15 × 106cells·mL-1High concentration microcystic aeruginosa culture during algae cell density logarithm reduction uv light irradiation
Intensity-effect relation, the relation curve substantially conform to logarithmic curve, goodness of fit R2=0.977, specific fitting formula is as follows：
+ 1.20 (R of y=-1.33*exp (- x/250.96)2=0.977)
In 20~81mWscm-2Uv light irradiation strength range in when, the logarithm of Microcystis aeruginosa Strains density is reduced
Level off to 0, i.e. its cell density maintains a more stable numerical value, and Microcystis aeruginosa Strains were grown in 9 day time
It is suppressed.Uv light irradiation intensity-effect logarithmic relationship shows, 26mWscm-2Logarithm in dosage algae cell density 9 days subtracts
It is less 0, i.e. algae cell density does not increase, it is thereby possible to select the uv light irradiation intensity (26mWscm-2) as highly concentrated
Spend an a reference value of algae solution and ultraviolet light intensity control.
