In this article, analysis the A2/O humic activated sludge system phosphorus removal efficiency and CODCr removal efficiency at 5°C, 10°C and 25°C. The results show that A2/O humic activated sludge system phosphorus removal rate when the influent temperature is above 10°C maintained at 86.1% ~ 97.5% performed high phosphorus removal efficiency. But at 5°C the system’s phosphorus removal efficiency decreased to 58.31% couldn’t get the sewage discharge standard. The variation of influent temperature had little influence on the removal efficiency of CODCr even at 5°C performed high removal efficiency.
