| 摘 要： | 目的研究A2/O-膜生物反应系统(MBS)工艺中水力停留时间、温度、载体粒径对生活污水化学需氧量(COD)去除率的影响以及粪大肠菌群浓度的变化。方法采用一座6层办公楼的污水,经A2/O-MBS工艺处理,测定水中COD的去除率以及粪大肠菌群浓度,进行检验及分析。结果水力停留时间为12 h、室温下、选择粒径为100~120目的竹炭/聚乙烯醇缩甲醛为载体,经A2/O-MBS污水处理装置处理后,出水COD平均去除率为99.45%;粪大肠菌群下降至23.0个/L,下降率为99.999%。结论A2/O-MBS工艺对生活污水中的有机物均有较好的去除作用,而且能够有效去除污水中的粪大肠菌群。

| Abstract: | ObjectiveTo study the influence of anaerobic-anoxic-oxic-membrane biofilm system(A2/O-MBS) on chemical oxygen demand(COD) and fecal coliform concentrations in domestic wastewater.MethodsThe domestic wastewater was treated with an A2/O-MBS.The concentrations of COD and fecal coliform in the wastewater were analyzed before and after the treatment and the difference was measured.ResultsUnder the condition of bamboo charcoal/polyvinyl formal composite material of 100-120 mesh diameter as a carrier,at normal temperature and 12 hours of hydraulic retention time,the removement rates of COD was 99.45%,and the decrease rate of fecal coliform was 99.999% for the wastewater after treated with A2/O-MBS.ConclusionThe most of the organic matter and fecal coliforms in domestic wastewater could be removed by using the A2/O-MBS. |
