Method.
Background technology
At present, algal bloom is one of worldwide water environmental problems the most prominent, and the development with global economy and
The expansion of the effect of human activity and be on the rise.China's bloom blue algae phenomenon is particularly acute, most of rivers, lake even reservoir
In all have the generation of wawter bloom to some extent, the lake algal bloom such as Taihu Lake, Dian Chi, Chaohu is even more to occur now and then.Bloom blue algae
Phenomenon large area, take place frequently for a long time, not only broken up function of lake and ecological environment, and threaten health and life drink
With the safety of water, oneself turns into one of main Environmental Problems of puzzlement China's economic sustainable development.But at present, people are blue to wawter bloom
The formation mechenism of algae is not completely clear and definite, also in the further investigation stage.

Born of the same parents, by the air bag number and volume in the pseudo- ghost of dynamic regulation, enable blue-green algae to control its buoyancy.Based on its unique physiology
(for example there is feature pseudo- vacuole to cause it has to float for the formation of cell colony, cell caused by the exocellular polysaccharide of cell secretion
Physiology to the water surface tends to), under a series of conditionings such as light intensity, temperature, wave disturbance, blue-green algae forms flocculation by colliding
Big colony, and the floating upward quickly formation visible wawter bloom in surface --- i.e. wawter bloom " outburst ".It is generally acknowledged that bloom blue algae formation includes phase
Mutually difference and continuously Four processes：Sinking and survive the winter (dormancy), --- floating shape is assembled in recovery --- biomass increase ---
Into wawter bloom, and understand blue-green algae recovery --- onset process bloom prealarming with control in it is significant.
Because the resuscitation process of bloom blue algae is considerably complicated, simultaneously as the limitation of field monitoring technology, blue for wawter bloom
Algae recovers and the understanding of process still neither one completely from bed mud into water body to outburst floating.Therefore, in a short time
In the case that bloom blue algae problem still seldom arrives basic solution, for quick, comprehensive grasp bloom blue algae outburst information, simulation is ground
Study carefully the excrescent method and apparatus of blue-green algae to be particularly important.
