Foster behavior, and light is exposed to, it adopts autotrophy behavior.Therefore, by change adjustable plate (212,213) in circulation of fluid light
Characteristic is learned, the behavior of microalgae is have modified, this is advantageously used in makes the behaviour adaptation of the microalgae be present in Cyclic culture medium
Nutrients characteristic.
Fig. 3, the culture medium for regularly preparing is injected in pipeline.The culture medium is by microalgae and aqueous mixture
Three types composition mixing.According to first embodiment, the microalgae is tied with the effluent (311) for including mineral nutrition thing
Close.This effluent is especially to be digested in advance by the bacterium of consumption organic matter.As an example, the effluent is the leaching discharged
Filtrate, methanation biogas residue and biogas liquid or building sewage.The effluent is combined with carbon dioxide (312).The embodiment is more specifically
It is suitable to produce microalgae by preferentially realizing the autotrophy behavior of the microalgae.The generation pattern makes it possible to reach per liter of a few gram quantity
The microalgae concentration of level.On the other hand, the embodiment is caused in the unusable effluent increment of other field.
According to another embodiment, effluent (313) is including organic nutrient substance.The embodiment advantageously uses food organic waste
The waste unworthy in other areas of thing, such as cannery, slaughterhouse or restaurant.The embodiment is by the way that microalgae is protected
Exist at lucifuge to use the heterotrophism behavior of microalgae.The embodiment allows to produce per liter hundred microalgae for carrying out gram quantity level.
Characteristic regardless of the effluent for being used, effluent in appropriate device (350) by micronized, to increase
Exchange surface between microalgae and the nutrients.File US2009 0029445 describes the example of atomization process.
Fig. 4, regularly extracts a certain amount of culture medium to extract microalgae.Culture medium when in culture medium microalgae it is dense
When degree with reaction more than corresponding threshold value is slowed down, the extraction is realized according to the concentration.Advantageously, fluid passes through adaptive device
And undergo flocculation operation (450).The flocculation operation makes it possible to promote to extract the microalgae, and the wherein microalgae is greatly reduced
Size does not allow to use membrane separation technique or Direct Filtration Technology, unless disappeared than reclaiming the microalgae for the filter operation
Consumption more multi-energy.Therefore, methods described (450) makes it possible to separate to prepare with the water (414) reused by the microalgae
Culture medium.Microalgae (415) is dispatched in the value-added field of energy, such as preparing biodiesel.
Advantageously, by means of making culture medium undergo the method for electric pulse to realize flocculation process.This method for example exists
Described in file WO2012 054404.
Above description and implementation example show to invention achieves expected purpose, and especially, it leads to according to positive energy process
Cross the thermal conditioning of realizing building and cause the increment of contaminative effluent.
