| 摘 要： | 按照20%的投配比向好氧池中投加悬浮式填料,将传统A2/O 工艺转变为A2/O复合式生物膜工艺.以实际市政污水为处理对象,考察了如何强化反硝化除磷效果的方法.结果表明,通过改变污泥龄从而适当的增加装置中污泥浓度可以有效的提高缺氧区反硝化除磷的效果,当SRT=Bd时,装置总体的处理效果最好.COD,总氮,氨氮和总磷的去除...

| Abstract: | A bench scale apparatus was set up to simulate the wastwater treatment system of anaerobic-anoxic-oxic(A2/O) with a certain amount of suspended media being added into the oxic compartment.The experiment on the system focused on enhancing the efficiency of denitrifying phosphorus removal of the wastewater from a local municipal wastewater plant by means of changing sludge retention time(SRT).Result showed that SRT of eight days comes the optimum performance of the wastewater system in terms of removals of CO... |
