Abstract:

选取溶解氧(DO)浓度和出水氨氮(NH_4~+-N)浓度作为控制因素,探究不同温度和有机碳源投加量(COD/NH_4~+-N)下,实现生物膜工艺短程硝化的可行性和对DO/NH_4~+-N值(R值)的需求.15,20,25℃时,实现短程硝化的R值分别约为0.08,0.17,0.25,说明比值控制可实现短程硝化,且R值的降低可弥补温度降低的不利影响;DO为3.5mg/L,NH_4~+-N浓度为14mg/L时,短程硝化实现,而DO和NH_4~+-N浓度分别为1.8,3mg/L,短程硝化破坏,说明实现生物膜反应器短程硝化,由DO/NH_4~+-N决定,而不仅仅是DO;有机碳源含量分别为0,60mg/L...
