中文摘要：
试验以A^2／O工艺为研究对象，动态模拟实际污水处理厂的运行情况，对该工艺连续动态监测了40h。研究结果表明，进水流量和进水水质变化对系统的去除效果并未产生较大影响，有机物、氨氮和磷的平均去除率可分别稳定在83％、98％和98％左右，这表明系统具有较强的抗冲击负荷能力；但对脱氮率和聚磷菌的厌氧释磷量会产生较大的影响；在同一连续流反应装置中同时实现了较为明显的缺氧吸磷和同步硝化反硝化作用，曝气量和碳源需求量可分别节省15．1％和11．5％。
英文摘要：
A^2/O process was continuously monitored for 40 hours in the experiment to simulate dynamically the operating condition in the practical wastewater treatment plant. It was indicated from the results that the average removal rate of organic matter, ammonia nitrogen and phosphorus in A^2/O process were 83%, 98%, 98%, respectively; A^2/O process was hardly influenced by the change ofinfluent flow and influent quality and had strong capacity of anti-impact load; but it had a rather large influence on the total nitrogen removal rate and anaerobic phosphorus release of phosphorus-accumulating organism in the reactor. In addition, the obvious anoxic phosphorus removal and simultaneous nitrification and denitriflcation were instantaneously achieved in the same continuous-flow reactor, which could save aeration quantity by 15.1% and carbon resource demand by 11.5%.
