Based on the consideration that the limited aeration may strip hydrogen sulfide out and oxidize part of the sulfide into nontoxic elemental sulfur,limited aeration was introduced into the reactor later to reduce the inhibition.

Experimental results showed that sequencing batch reactor system to be operatted in a limit aeration schedule can not cause sludge increase rapidly.

In the starting process, stable shortcut nitrification of whole course nitrifying sludge achieved by time limiting aeration after 30d.

Fuzzy control of SBR aeration rate;

Study on effects of C/N ratio and aeration rate on the simultaneous nitrification and denitrification(SND) in MBR

The results show that the removal efficiencies of ammonia nitrogen and COD are more than 95% and 90% respectively when the aeration rate is 0.

Through a test for treatment of vehicle washing wastewater by MBR,the least aeration quantity for lessening membrane pollution was found out.

Microaerobic biological technology was used for methanol wastewater treatment through a lab-scale experiment at room temperature,the relationships of removal efficiency of COD with influent COD,aeration quantity and aeration time were discussed.

By increasing the amount of the aeration and residual effluent sludge,and improving the technological parameter,the effluent can reach the standard of the GB18918-2002 No.
