摘要
采用模拟生活废水对比分析了生物膜反应器的2种挂膜方法 (自然挂膜法和接种挂膜法),并探究了HRT和DO对生物膜反应器去除COD和NH_4^+-N的影响。结果表明:同等工况条件下,采用接种挂膜法和自然挂膜法的COD和NH_4^+-N去除率分别为85.3%、67.8%和84.6%、66.2%,采用自然挂膜法完全可以取得接种挂膜法的效果;HRT和DO对生物膜反应器去除COD和NH_4^+-N有着重要影响,当HRT为6 h,DO为4.0 mg/L时,COD和NH_4^+-N去除率分别为90.2%和85.5%。
Two bio-film forming methods of bio-film reactor,including natural bio-film formation,and inoculation bio-film formation,have been comparatively analyzed,using simulated domestic sewage. The influences of HRT and DO on the removal of COD and NH4＋-N in the bio-film reactor are implored. The results show that the removing rates of COD and NH4＋-N by inoculation bio-film formation and natural bio-film formation under the same working condi-tion are 85.3%,67.8%and 84.6%,66.2%,respectively. Using natural bio-film formation can completely obtain the same effect as that obtained by inoculation bio-film formation. HRT and DO have important influences on the remov-ing rates of COD and NH4＋-N in bio-film reactor. When HRT is 6 h and DO 4.0 mg/L,the removing rates of COD and NH4＋-N are 90.2%and 85.5%,respectively.
