| 摘 要： | 在序批式活性污泥反应器(SBR)中,以模拟城市污水为处理对象,考察了在稳定运行期间的典型周期里COD、TP、TN、DO、pH以及ORP的变化规律。试验表明,在SBR反应器中实现短程同步硝化反硝化耦合除磷是完全可行的,在温度为20～25℃、pH值为7.12～7.43的条件下,系统对COD的去除率达到95.6%,对TP和TN的去除率分别为88.8%和87%,实现了短程同步硝化反硝化与反硝化除磷的统一。

| Abstract: | The variation of COD, TP, TN, DO, pH and ORP in a typical cycle during stable operation of SBR for simulated municipal sewage treatment was investigated. The tests show that the coupling of short-cut simultaneous nitrification and denitrification with denitrifying phosphorus removal in SBR is completely feasible. Under the conditions of temperature 20 to 25 ℃ and pH 7.12 to 7.43, the removal rates of COD, TP and TN are 95.6%, 88.8% and 87% respectively. The unification of short-cut simultaneous nitrification and denitrification with denitrifying phosphorus removal is realized. |
