摘　　要：在引进、消化、吸收日本先进的废水生化处理技术(BBR系统)及对该技术进行国产化研究的基础上,设计了一组处理量为6 m^3/d的市政污水小型动态试验,并按照曝气池的溶解氧(DO)控制方式分别进行了3组对比试验。结果表明,当曝气池按DO浓度递增的方式控制,即1~#曝气池10%、2~#曝气池20%、3~#曝气池30%、4~#曝气池40%时,BBR系统对各污染物的去除率最高,即BBR系统在该DO控制条件下的处理效果最佳。Based on the introduction, digestion and absorption of the advanced wastewater bio- chemical treatment technology （BBR system） from Japanese and the domestic research on the technolo- gy, a set of small-scale dynamic tests with the capacity of 6 m3/d were designed, and three groups of contrast tests were carried out respectively according to the control method of dissolved oxygen （DO） in aeration tanks. The experimental results showed that when DO in the aeration tanks increased incremen- tally, namely 10% for 1 # aeration tank, 20% for 2# aeration tank, 30% for 3# aeration tank and 40% for 4# aeration tank, the removal rates of various pollutants were the highest, which showing that BBR system had the optimal treatment efficiency under the DO control conditions.
