摘　　要：在DO质量浓度为1.5 mg/L、温度为28℃等条件下,NO2--N积累率>50%,系统实现短程硝化。硝化率为77.35%,反硝化率83.25%,SND率64.74%,HMBR实现同步短程硝化反硝化。COD平均去除率为91.61%,NH3-N去除率77.34%,TP去除率45.13%,且膜对COD、TP有截留作用。在系统实现耦合作用后对有机物有去除效果。Under the DO=1.5 mg/L and temperature for 28 ℃ condition, accumulation rate of NO2-N 〉50%, HMBR has achieved shortcut nitrification. The removal rates of NH3-N, d-enitrification, SND are 77.35%, 83.25%, 64.74%, HMBR has achieved SND. The removal rates of COD, NH3-N, TP are 91.61%, 77.34%, 45.13%. Membrane has inter-cept effect on removaling COD, TP. When HMBR has achieved couple action, it has effect on removaling organics.
