| 摘 要： | 对厌氧折流板反应器（anaerobic baffled reactor,ABR)在微氧条件下的运行特性进行试验研究，分析了ABR在微氧条件下高效运行的可行性。研究结果表明，适量氧的加入能使ABR的COD去除率提高，出水VFA浓度降低。进水COD为4 000 mg/L,HRT为12 h的相同条件下与厌氧相比，微氧ABR出水COD和VFA浓度的降幅分别为63.7%和66%；微氧ABR内氨氮的去除主要通过同步硝化反硝化和短程硝化反硝化作用；适量氧的加入可以提高微生物的产甲烷活性。

| Abstract: | In order to analyze the feasibility of the highly efficiently and stable operation of the anaerobic baffled reactor(ABR)under the microaerobic condition.The performance characteristic of the ABR under the microaerobic condition was investigated.The results showed that supplement of limited oxygen could increase the COD removal efficiency and decrease the effluent VFA concentration.For the influent COD of 4 000 mg/L with HRT of 12 h,the decrease percentage of the effluent COD concentration and the VFA concen... |
