摘　　要：以某城市污水为处理对象,采用A^2O-MBR集成工艺,研究了季节性变化对其脱氮除磷效果的影响。结果表明,COD、NH_3^-N、TN、TP的月平均出水浓度范围分别为(17.4~45.4)、(0.82~4.00)、(6.55~15.61)、(0.30~0.38)mg/L,且对COD的去除在12月份(温度<13℃)受到影响,月平均出水浓度明显升高;对TP的去除基本未受季节性变化的影响;对TN和NH_3^-N的去除受季节性变化的影响较大,在冬季低温下去除效果明显下降。The effect of seasonal variation on nitrogen and phosphorus removal efficiency in A^2O/ MBR for treatment of the municipal wastewater from a city was investigated. The results showed that the monthly average effluent concentrations of COD, NH3 - N, TN and TP were 17.4 to 45.4 mg/L, 0.82 to 4.00 mg/L, 6.55 to 15.61 mg/L and 0.30 to 0.38 mg/L respectively. The removal efficiency of COD in December （less than 13 ℃ ） was affected, and the monthlyaverage effluent concentration of COD was increased. TP was not affected by seasonal variation. TN and NH3 -N were signficantly affected by seasonal variation, and their removal efficiency decreased significantly in low temperature in winter.
