| 摘 要： | 以模拟废水为处理对象,采用一套特定的MBSBBR系统,研究了COD负荷率对COD和NH4+-N去除率的影响,验证并分析了系统的SND现象。实验结果表明:COD负荷率为2.88～4.96kg/(m3·d)时,NH4+-N的去除率在70%左右,TP去除率在85%左右。系统对有机物具有良好的去除能力,可以承受较高的有机负荷率。系统中存在SND现象,反硝化菌大量存在,反硝化过程的碳源主要来自生物膜。系统的污泥产率较低,随着COD负荷率的增大而略有提高。

| Abstract: | A type of specific MBSBBR for treatment of simulated wastewater was used to study the effect of COD load on removal of nitrogen and phosphorus.The simultaneous nitrification and denitrification(SND)of the system was validated and analyzed.Results showed that when volumetric loading rate of COD was 2.88～4.96kg/(m3·d),the removal efficiency of NH4+-N and TP was 70% and 85% respectively.The system was able to endure high COD load and had excellent removal of organic matter,with SND phenomenon and a lot of denitrification bacteria in the system. |
