Abstract:
首先采用分段进水多级A/O工艺处理低C/N值生活污水,通过投加乙酸钠强化反硝化性能,并针对试验过程中出现的污泥膨胀、碳源利用率低等问题,提出了多级A/O耦合生物膜反硝化强化脱氮工艺。探究C/N值对多级A/O工艺以及耦合系统性能的影响,并对比两者的异同;同时通过批式试验考察了碳源类型对污泥沉降性能的影响。当进水C/N值为2~5时,两种工艺对COD的去除效果差异不大,出水COD均低于50 mg/L。两者去除NH_4~+-N的差异较大,当C/N值=5时多级A/O工艺对NH_4~+-N的去除率为88.8%,出水NH_4~+-N高于5 mg/L,而耦合工艺受C/N值的影响不大,对NH_4~+-N的去除率...
