摘　　要：基于An/O—SBR工艺,探讨了反应温度分别为15和25℃时,进水COD/TP(C/P)值对生物除磷系统的影响;并将进水总磷浓度恒定为(10±0.5)mg/L,以比较两温度下的厌氧段末释磷量和最终出水TP浓度。结果表明:在15和25℃下,随进水C/P值的升高,出水TP浓度降低,当C/P≥40时,出水TP<1 mg/L;在25和15℃下,厌氧段释磷量与进水C/P值均呈线性相关;在进水C/P值相同的条件下,15℃时对TP的去除率比25℃时的平均高5%左右。Based on An/O -SBR process, the influence of the influent COD/TP （C/P） ratio on the biological phosphorus removal system at different temperatures （ 15 ℃ and 25 ℃ ） was discussed. The influent total phosphorus concentration was constantly controlled at （ 10 ± 0.5 ） mg/L to compare the phosphorus release amount at the end of anaerobic stage and the final effluent TP concentration at both temperatures. The results show that the effluent TP concentration decreases with the increase of the influent C/P ratio at 15 ℃ and 25 ℃. When the influent C/P ratio is equal to or more than 40, the effluent TP concentration is lower than 1 mg/L. At 25℃ and 15 ℃ , there is a good linear correlation between the phosphorus release amount at the end of anaerobic stage and the influent C/P ratio. The TP removal rate at 15℃ is 5% higher than that at 25 ℃ when the influent C/P ratio is the same.
