Description
Technical field
The utility model relates to a kind of street cleaner's environmental protection ship waterborne, relates in particular to a kind of street cleaner's multifunctional environmental-friendly ship equipment waterborne.
Background technology
It is global problem that blue-green algae breaks out.The lake nutrient laden day by day seriously is the main cause that causes blue algae growth and break out, and global warming, water temperature rising also are the inducements that blue-green algae breaks out simultaneously.As long as the lake nutrient concentration pollutes even cut off external source fully for a long time in the higher level fluctuation, as long as conditions such as temperature, current, illumination are suitable, blue-green algae breaks out probably on a large scale.Even this phenomenon under the condition of taking very strict control measures, still can continue 3-5 even longer time, this trend can't change in the short time.So the blue-green algae in lake is administered and ecological recovery is a long-term process.
Large-scale blue-green alga bloom was broken out in important waters such as Chinese yunnan Dian Chi, Taihu Lake, Jiangsu in succession in recent years.Serious environment pollution endangers the drinking-water water source on the one hand; Brought great influence to tourist industry on the other hand.Especially Taihu Lake is as the important drinking water earth surface water source in Wuxi, and blue algae bloom causes the Wuxi that the water crisis takes place.How to alleviate even eliminate blue-green algae and pollute, become a problem that presses for solution.
The eutrophication in lake has been the gesture that bad old practices die hard at present, wants thoroughly to solve the blue-green algae problem in the short time, all goes back the good method of neither one maturation both at home and abroad.
It is very general that the blue-green algae phenomenon takes place storehouse, large-area lake water body, and blue-green algae is all taken place in many lakes both domestic and external.Body eutrophication is meant nutriments such as nitrogen that admittance in lake, reservoir and the river is too much and phosphorus, and the ecologic structure of water body and function are changed, and causes the algae particularly unusual breeding growth of blue-green algae and the blue-green alga bloom phenomenon that occurs.When blue-green alga bloom is serious, the water surface forms thick blue-green water bloom, give off an unpleasant smell, not only destroyed aquatic ecosystem in a healthy and balanced way, and the drinking water safety of humans and animals has been constituted serious threat because of frustule discharges multiple algae toxin after breaking.
At present, the frequency of freshwater lake blue-green alga bloom generation is serious day by day in the world.In the past, lake blue algae is stacked formation secondary pollution easily behind the elsewhere based on artificial salvaging.The algae moisture that Nanjing University Yixing environmental protection science and technology research and development centre relates to the blue-green algae pick-up boat from, concentrate world-class technical barrier such as mummification and assault, they and Jiangsu Ding Ze Environmental Projects Inc. unite tackling key problem, only used more than 30 day test and research, obtained important breakthrough with regard to the key technology that makes " blue algae dewatering belt filter press ".After " blue algae dewatering belt filter press " sucked green algae water, the way that adopts composite flocculation was discharged by concentrating press filtration the initial gross separation of algae water then with clear water, form the algal biscuit of mummification simultaneously.The birth of this technological achievement is that the mechanization of blue-green algae fishing is laid a good foundation.At present, Jiangsu Ding Ze has finished the production of first batch of equipment and has come into operation.The expert thinks, this pick-up boat of blue-green algae is efficiently salvaged blue-green algae, is the most direct, the most effective at present, blue-green algae improvement method the most fast.
But above-mentioned technological achievement exists, and hull is huge, complex process, equipment heaviness and the low shortcoming of treatment effeciency, especially can only merely handle blue-green algae and can only handle the blue-green algae layer in other words.

3, operating principle
Blue-green algae breaks out, and is that flow rate of water flow is slow excessively because eutrophication is comparatively serious in the water body, and water exchange capacity is little.
As Fig. 5, studies show that, there is air bag in the blue-green algae cell, there is gas in the air bag.Air bag is piled up by numerous cylindrical bubbles and forms, and people are the pseudo-cavity of these bubble called afters.It mainly acts on is to provide buoyancy for cell.The pseudo-cavity of blue-green algae is to be taper by its two ends that protein constitutes, middle for cylindrical hollow, be filled with the cell inner structure of gas; Wall thickness is 2nm only, wide 45-110nm, long 100-800nm or longlyer do not wait.
Pseudo-cavity feature:
1) has hydrophobic inner surface, can stop hydrone to enter, and gas molecule can freely spread turnover.
2) have rigidity, when pseudo-cavity increased 0.1MPa at the pressure that bears, its volume only dwindled 1/1000.
As long as pseudo-cavity does not break, just can provide buoyancy for blue-green algae.By the blue-green algae characteristic as can be seen, want to remove the buoyancy that blue-green algae will be destroyed blue-green algae, the algae on design water body top layer (0-200mm) removes the pressurization of blue-green algae system through fore, destroys blue-green algae air bag and eucaryotic cell structure, reduces cell buoyancy, impels blue-green algae to sink.When removing the work of phytem system, water inlet sucks the blue-green algae cell suspension on top layer, removing the pressure of phytem system generation breaks up the group of the blue-green algae in the water, and make the balloon rupture of blue-green algae cell, cytoclasis through the absorption of kieselguhr efficient flocculant, is discharged through delivery port more then, sink in the water body, reach purpose except that algae.
According to noted earlier, generally about 100nm, therefore can get the ruined pressure of blue-green algae is about 0.4MPa to the blue-green algae diameter.Show that by the blue-green algae pressure test when pressure during greater than 0.4MPa, algae can be precipitated rapidly, illustrates that blue-green algae air bag and eucaryotic cell structure are destroyed.Therefore the minimum working pressure power of determining the balancing gate pit is 0.4MPa.The balancing gate pit is realized by compression pump and backflow safety valve, can satisfy minimum working pressure power.
Kieselguhr (clay mineral) blue-green algae flocculant is the fabulous rare natural materials of absorption blue-green algae, not only has higher usefulness, and the source is sufficient, with low cost, nontoxic pollution-free, also less to the influence of non-algal tufa biology, be considered to a kind of natural flocculant of administering algal tufa.The big 50-60m of kieselguhr blue-green algae flocculant specific area
2/ g can be adsorbed on blue-green algae in its human body and is sunken to lakebed.
Blue-green algae is adsorbed in the kieselguhr human body and is sunken to lakebed this be of the present utility model one big characteristic:
One can also can discharge toxic gas harm water body by a large amount of consumption lakebed dissolved oxygens if be sunken to lakebed after blue-green algae is vanished separately, and existing just the parcel by kieselguhr absorption can not endangered water body
Its two, kieselguhr is sunken to the eutrophy-nitrogen that can block the sunlight of bed mud in the lake behind the lakebed and cause bed mud, phosphorus and is not released, the growth of blue-green algae will be curbed like this.
As everyone knows, " blue-green alga bloom " be lake water by the sign of severe contamination, be the serious eutrophication of water body and cause the principal element of blue algae bloom, eradicate blue-green algae and must set about from eutrophication.For this reason, main task of the present utility model is exactly that denitrogenation is scaled, and fundamentally roots out the material base of blue-green algae existence, bad five class lake water is handled rising to more than the four class water quality, and handling blue-green algae is the byproduct of street cleaner's environmental protection ship waterborne.
4, result of the test
