摘要：
A modified, laboratory-scale, oxic/anoxic process with zeolite circulation achieved a high efficiency (97%) of nitrogen removal from synthetic wastewater. This process lowered the turbidity and the suspended solid concentration in the effluent. The zeolite was effective as a biomedium due to the formation of biofilm on the surface of zeolite and the continuous biological regeneration.
