Description
Technical field
The invention belongs to algae and water concentration, environmental technology fields.It is more particularly to a kind of air recoil and washes continuous concentration
The method of algae slurry also relates to the device that a kind of air recoil washes continuous concentration algae slurry, it is suitable for algae slurry and is concentrated through two-stage
The dehydration of device drainage, compressed air back-washing system stripping algae, become the semi-solid phase algal gel that can directly pack.
Background technology
Lake blue algae wawter bloom is controlled there are many method, including physics, chemistry and biological method, wherein machinery is salvaged, cyanobacteria
The physical methods such as collection, are that can directly remove lake cyanobacterial bloom at present, and the method without negative effect.It is beaten using machinery
Fishing and blue algae collecting method can generate a large amount of algae slurries, these algaes slurry contains a large amount of moisture content, water content of Cells of Blue-green Algae living itself
90% or so, algae starches moisture content generally up to 95%-99%.Excessively high moisture content, not only pole be unfavorable for algae slurry transport and
Storage also brings many difficulties to the follow-up disposition of algae slurry.Contain in algae slurry containing abundant phosphorus and nitrogen, vegetable protein
Amount is high, easily corrupt, distributes stench, and there are secondary pollution danger.The dewatering of algae slurry is poor, using conventional vibration filtering,
The dewaterings effects such as slanted screen filtering, vacuum suction filter, press filtration are poor.In order to accelerate the dehydration of algae slurry, generally use addition flocculant
Flocculant mating band is added after coordinating the method (such as patent CN200710066435.6) of decanter centrifuge or algae slurry secondary filter
The method of formula filter press and decanter centrifuge (such as patent CN200810048488.X).But the method for using addition flocculant, both
Increase cost, and the algal gel of generation is made to be unfavorable for subsequent recycling.Therefore for a long time, algae starches reluctant problem
An important factor for as the improvement of lake blue algae wawter bloom is restricted.
Invention content：
It is easy to implement the method the purpose of the invention is to provide a kind of method that air recoil washes continuous concentration algae slurry, behaviour
