为了提高脱氮除磷的效率，采用序批式生物反应器（SBR）工艺处理模拟生活污水，考察了不同温度下N/P、污泥龄（SRT）对厌氧/好氧/缺氧序批式生物反应器（AOA-SBR）工艺同步脱氮除磷效能的影响。结果表明：当温度为10℃、N/P为2～3、SRT为20 d时，NH4+-N、TN和TP去除率分别为78%、69%和56%，污泥产率YS为0.339 kgSS/(kgBOD5)，污泥含磷率PC为4.68%。当温度为25℃、N/P为3～5、SRT为15 d时，NH4+-N、TN和TP的去除率分别为88%、83%和91%，污泥产率YS为0.253 kgSS/(kgBOD5)，污泥含磷率PC为6.35%。当温度为35℃、N/P为5～7、SRT为10 d时，NH4+-N、TN和TP去除率分别为80%、66%和73%，污泥产率YS为0.225 kgSS/(kgBOD5)，污泥含磷率PC为7.42%。污泥产率YS随着温度和污泥龄的增加而降低，通过调节温度和污泥龄能够实现污泥减量。
為瞭提高脫氮除燐的效率，採用序批式生物反應器（SBR）工藝處理模擬生活汙水，攷察瞭不同溫度下N/P、汙泥齡（SRT）對厭氧/好氧/缺氧序批式生物反應器（AOA-SBR）工藝同步脫氮除燐效能的影響。結果錶明：噹溫度為10℃、N/P為2～3、SRT為20 d時，NH4+-N、TN和TP去除率分彆為78%、69%和56%，汙泥產率YS為0.339 kgSS/(kgBOD5)，汙泥含燐率PC為4.68%。噹溫度為25℃、N/P為3～5、SRT為15 d時，NH4+-N、TN和TP的去除率分彆為88%、83%和91%，汙泥產率YS為0.253 kgSS/(kgBOD5)，汙泥含燐率PC為6.35%。噹溫度為35℃、N/P為5～7、SRT為10 d時，NH4+-N、TN和TP去除率分彆為80%、66%和73%，汙泥產率YS為0.225 kgSS/(kgBOD5)，汙泥含燐率PC為7.42%。汙泥產率YS隨著溫度和汙泥齡的增加而降低，通過調節溫度和汙泥齡能夠實現汙泥減量。

The simulated sewage wastewater was treated continuously using SBR process in order to improve the removal efficiency of nitrogen and phosphorus. Effects of mass ratio of nitrogen to phosphorus(N/P)and sludge retention time(SRT)on simultaneous nitrogen and phosphorus removal were investigated by using anaerobic/aerobic/anoxic sequencing batch reactor (AOA-SBR) at different temperatures. The results showed that removal efficiencies of NH4+-N,TN and TP were 78%,69%and 56%,respectively,and sludge yield (YS)was 0.339 kgSS/(kgBOD5),and phosphorus content in the sludge was 4.68%under the condition of N/P of 2-3 and SRT of 20d at 10 ℃. The removal efficiencies of a NH4+-N,TN and TP weer 80%,66%and 73%,respectively and sludge yield (YS) was 0.225 kgSS/(kgBOD5), and phosphorus content in the sludge was 7.42%under the condition of N/P of 5-7 and sludge age of 10d at 35 ℃. The removal efficiencies of NH4+-N,TN and TP were 88%,83%and 91%,respectively and sludge yield) (YS)was 0.253 kgSS/(kgBOD5),and phosphorus content in the sludge was 6.35%under the condition of N/P of 5-7 and SRT of 15d at 25 ℃. Sludge yield was reduced with the increasing temperature and SRT,and sludge reduction can be realized by adjusting the temperature and SRT.
