摘　　要：在传统A/O或SBR工艺的基础上投加沸石粉进行强化生物脱氮,吸附饱和的沸石粉利用微生物进行再生,形成了沸石强化生物脱氮工艺。实验结果表明,沸石粉可在生物池中累积达到一定的平衡浓度;在常温下沸石粉对过量氨氮选择吸附的优势无法发挥,但在低温时可以保证处理出水中氨氮浓度达标;不同投加方式影响工艺处理效果,在低温情况下,“集中投加”的启动方式优于“逐步投加”的运行方式。Adding zeolite to the traditional A/O or SBR process for enhancing nitrogen removal, and the adsorbed zeolite could be regenerated by microorganism, and formed enhanced nitrogen removal process. Experimental result showed: ① the concentration of zeolite in the biological reactor could reach an equilibrium power,② under ordinary temperature, the advantage of selecting exchange with excess nitrogen was unable to bring into play, while under low temperature, armmonia nitrogen concentration could decrease to meet the standard quality, and ③ different ways of adding zeolite could affect the efficiency of the process, and under low temperation batch-addition was superior to step-addition
