Treatment of Simulated High Salt Wastewater by Salt-tolerant Bacteria Enhanced SBR
The SBR reactor added with salt-tolerant bacteria has a COD degradation rate of about 93%at 3%salinity.With the increase of salinity,the SBR2 reactor has stronger resistance to salinity,which makes the system still have a good degradation effect on COD.The SBR reactor added with salt-tolerant bacteria has a significantly higher degradation effect on COD than the control group.When the salinity is less than 3%,the average NH4+-N removal rate of the SBR reactor is stable at 90%in the stable operation stage.When the influent salinity is lower than 3%,the SBR still has a high NH4+-N removal rate,and the synchronous nitrification and denitrification are significantly inhibited when the salinity is above 3%.Excessive salinity caused the death of sludge microorganisms.
