It wants, light source is timed switch, is controlled by programmable controller 14.
In fill phase, sewage is pumped into reactor cylinder 2 by intake pump 6 through water inlet pipe 3.
In agitation phases, stirring motor 10 works, and drives stirring rod 11, paddle 12, stirring turn brush 13 to synchronize same
The rotation of heart circle.The rotation of paddle 12 makes to form upward rotating vortex in reaction column, not only makes microorganism equal in sewage
Even distribution also provides certain shearing force for the culture of bacterium-algae granule sludge.And with the beginning of stirring, it increases stirring newly and turns
Brush 13 also with its rough surface but has certain elastic material property, as the friction with 2 inner wall of reactor cylinder will adhere to
Microalgae wadding body cleans on 2 inner wall of reactor cylinder, in case microalgae adherence growth is to influence inside reactor cylinder 2
Intensity of illumination.Simultaneously it has been investigated that compared to the free microalgae in reactor cylinder 2, the activated sludge of inoculation be easier with
The microalgae wadding body cleaned combines to form bacterium-algae symbiosis granule sludge.
In aeration phase, air compressor 8 is started to work, by compressed air through aeration head 7 in the form of micro-bubble
It is uniformly diffused into entire reactor cylinder 2.The bubble of aeration phase provides not only needed for nitration reaction and microbial metabolism
Oxygen, while also providing shearing force necessary to Granular sludge formation.
When entering bleeding stage by precipitate phase, drain valve 5 is started to work, by reaction sewage by drainpipe 4
Discharge.
In incubation, if sludge needs to be discharged, it can be discharged through mud discharging mouth 9.
Illumination, water inlet, aeration and draining in the above operation have programmable controller 14 to be controlled, and make whole system
It is more convenient, efficiently.
