Abstract: Two types of operation means “SBBR reactor alone (Sreactor)” and “adding zeolite powder into SBBR reactor (Z-Sreactor)” were used to treat municipal wastewater. The test results showed that zeolite added in reactor could improve the activity of the activated sludge. Due to the combination of zeolite adsorption for NH4+-N enhanced simultaneous nitrification andde-nitrification (SND), a higher nitrogen removal was observed in Z-S reactor compared to the S reactor, and the addition of zeolite powder is helpful to inhabit sludge bulking. Inaddition, through long-term parallel shock load test, it was found that the zeolite added in reactor could enhance the ability of activated sludge inresisting the shock load of organics and ammonium.
