摘　　要：实验对恒液位SBR工艺脱氮除磷的影响因素进行了研究,结果表明:当ρ(DO)在2～3mg·L-1,碳氮比[m(C):m(N)]达到8,泥龄在17d,污泥质量浓度在4500～6000mg·L-1,温度达到17℃时,TN的去除率在55%以上,TP的去除率可达90%。The effect factors of denitrification and phosphorus removal by constant liquid-level SBR was researched. It was found that when DO was.2 to 3 mg.L^-1, the ratio of carbon to nitrogen reached 8, SRT was 17days, MLSS was 4 500 to 6 000 mg.L^-1, and temperature was 17 ℃, total nitrogen removal efficiency was higher than 55% and total phosphorus removal efficiency was about 90%.
