摘要: 以北京某污水处理厂二期工程A2/O工艺为例，结合现场调查及小试试验，研究了A2/O工艺中降低供氧能耗的可行性。研究表明，已建污水厂A2/O工艺存在2种可操作的节能方法：一是严格控制曝气池中的DO，将DO控制在2～3 mg/L，避免过度曝气造成浪费；二是通过工艺调节，把好氧前段变成缺氧区，减少曝气段的长度，这种方式能节约17.1%的曝气量，同时增加约13.6%的TN去除率。

Abstract: The feasibility of saving energy for A2/O processes was studied in a wastewater treatment plant located in Beijing by means of field investigation and labscale experiment. The results indicate that there are two operable ways to save energy in A2/O processes. One is to control the DO strictly within 2～3 mg/L in aeration tank and to avoid over-aeration, the other is to shift the forepart of the aerated tank into anoxic tank, by which 17.1% of aeration could be reduced and about 13.6% of TN removal rate could be increased.
