Two, the principle of work of multi-functional environment-protection method
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.
Like Fig. 5, research shows, has air bag in the blue-green algae cell, has 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 for cell buoyancy to be provided.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, and long 100-800nm or longer does not wait.
Pseudo-cavity characteristic:
1) has hydrophobic inner surface, can stop hydrone to get into, 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 buoyancy be provided for blue-green algae.Can be found out by the blue-green algae characteristic, 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, removes the pressure of phytem system generation the group of the blue-green algae in the water is broken up; And make the balloon rupture of blue-green algae cell; Cytoclasis through diatom earth enhanced flocculation agent absorption, is discharged through water outlet 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 through the blue-green algae pressure test when pressure during greater than 0.4MPa, algae can be precipitated rapidly, explains that blue-green algae air bag and eucaryotic cell structure are destroyed.Therefore the minimum working pressure power of confirming the pressure chamber is 0.4MPa.The pressure chamber is realized by force lift and backflow safety valve, can satisfy minimum working pressure power.
Diatom earth (clay mineral) blue-green algae flocculant is the fabulous rare natural material 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 that non-algal tufa is biological, be considered to a kind of natural polycoagulant of administering algal tufa.The big 50-60m of diatom earth blue-green algae flocculant specific surface 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 diatom earth human body and is sunken to lakebed this be of the present invention one big characteristic:
One of which can also can discharge noxious gas harm water body by lot of consumption lakebed dissolved oxygen if be sunken to lakebed after blue-green algae is vanished separately, just can not endangered water body by diatom earth absorption parcel at present
Its two, diatom earth 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 out, 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 gross pollution, 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 invention is exactly the denitrogenation dephosphorization, fundamentally roots out the material base of blue-green algae existence, bad five types of lake water is handled rising to four types more than the water quality, and handling blue-green algae is the side production of street cleaner's environmental protection ship waterborne.
