Description
Technical field
The present invention relates to a kind of raceway pond microalgae cultivating system for continuing aerating collecting frustule using microbubble, specifically relate to
And a kind of raceway pond of microalgae mass culture, belong to microdisk electrode engineering field.
Background technology
Microalgae is the most important primary producer of natural water, and the CO2 being secured by it accounts for global CO2 fixed amounts
More than 40%.Meanwhile microalgae cell is contour rich in polyunsaturated fatty acid, a variety of essential amino acids, active polysaccharide, pigment
Added value bioactive substance, make it that there is important application valency in fields such as functional food, cosmetics, medicine and fine chemistry industries
Value.In recent years, as global industry process accelerates to cause demand for energy to be continuously increased, and traditional fossil energy has not
Recyclability, reserves are increasingly being reduced.Study, develop a kind of renewable, environmentally friendly energy to meet the energy need of the mankind
Ask, reduce the destruction to environment, be the key subjects urgently to be resolved hurrily of facing mankind.Microalgae, has that the speed of growth is fast, grease contains
A series of features such as amount is high, cultivation cycle is short, have become most important bioenergy candidate species.
Open raceway pond because cost it is relatively low, easily operated the advantages that, extensively using and a variety of microalgaes pilot scale culture
(Chlorella, micro- plan ball algae, spirulina etc.).Because microalgae photosynthesis needs luminous energy and carbon dioxide;Therefore, in microdisk electrode
During, improve the utilization rate of carbon dioxide, the luminous energy total amount that the frustule in unit of water body receives, may consequently contribute to improve micro-
The yield of algae culture.The mode of harvesting microalgae, in addition to spirulina, other most of microalgaes are based on being collected by centrifugation.And centrifuge
The operating power consumption of machine is very big;Therefore, ratio of the cost being harvested by centrifugation in both culturing microalgae cost is very high.Improve centrifugation effect
Rate, harvest cost is reduced, the toxigenic capacity of microalgae can be greatly lowered.
, can be to 1mm or so when the penetration range of light is minimum with the increase of cell density during microdisk electrode.This
Mean in unit of water body, few a part of cell on only top layer can obtain enough luminous energy.Microalgae is in photosynthesis mistake
Cheng Zhong, only need illumination in cloudy, turbid phase.Even lasting illumination can cause certain damage to microalgae.Micro algae growth is come
Say, light-inner room is had a rest(Flash effect)It is optimal luminous environment;Therefore, it is necessary to effectively realize algae in raceway pond incubation
The frequent exchange of liquid levels water body, to cause the frustule of unit of water body both to obtain enough luminous energy, it turn avoid top layer algae
The light injury of cell.
Due to a series of shortcomings that traditional runway cell system has, the microalgae cell density for causing it to cultivate is not high enough, from
And the efficiency of crop that directly results in centrifuge is relatively low.In order to reduce energy consumption, centrifugal efficiency is improved, most manufacturers are harvesting
Before microalgae, algae solution is transferred to sedimentation basin.Through natural subsidence after a while, to reach the purpose of initial concentration microalgae.
But the efficiency of the method is poor, especially in face of some non-benthic type microalgaes when, it is even more so.In addition, due to big absolutely
Most cells are in dark surrounds the sedimentation for carrying out the long period, therefore this process both easy breed bacteria, can also cause phase
When biomass loss.Meanwhile shift all algae solutions to sedimentation basin, then by upper strata algae solution transport can raceway pond process, it is necessary to
Consume mass energy.
Microbubble in water body is attached to fine particle, during such as microalgae, because the effect of buoyancy can bring frustule to table
Layer water body.In the presence of having a large amount of microbubbles in algae solution, it will so that the frustule of unit of water body is largely assembled on top layer.If energy
It is enough that the frustule of larger unit of water body is enriched with to the top layer compared with subsection water body, and gather it, it will the effective, realization of low consumption
The initial concentration of frustule.So as to effectively reduce the toxigenic capacity of microalgae, and control microalgae quality.
