摘要/Abstract

摘要： 利用自主设计的一套新型生物膜反应器处理传统村落生活污水，采用人工投加活性污泥的挂膜方法对反应器进行挂膜启动，研究了 COD 负荷、C/N 比以及回流比对反应器运行效果的影响．实验结果显示:投加活性污泥的挂膜方式能够在较短的时期内挂膜成功，且挂膜过程中生物膜外观以及微生物相变化都较为明显;挂膜成功后，COD 和 NH₊⁴ -N 的去除率达到 85%以上; 在运行过程中，该生物膜反应器的运行效率受 COD 负荷、C/N 比和回流比的影响较大，在 COD 负荷为 0． 25 kg/(m² ·d)、C/N 比为 10． 2、回流比为 9． 17 时，反应器的 COD 和 NH₊⁴ -N 去除率最高，分别达到 91． 46%和 88． 65%．

Abstract: A new-type biofilm reactor started up by adding activated sludge manually was designed to treat the do- mestic wastewater in traditional villages,and the influences of COD load,C/N ratio and the reflux ratio on system operation were investigated.Experimental results show that (1) the addition of activated sludge helps successfully colony biofilm with good appearance and obvious microbial morphology variation in a short time; (2) both COD and NH₊⁴ -N removal efficiencies achieve more than 85% after the biofilm colonization; (3) the operating efficiency of biofilm reactor is greatly affected by COD load,C/N ratio and reflux ratio; and (4) the COD and NH₊⁴ -N removal efficiencies respectively achieve 91.46% and 88.65% at a COD load of 0.25kg/(m 2 ·d),a C/N ratio of 10.2 and a reflux ratio of 9.17.

Key words: biofilm reactor, domestic wastewater treatment, biofilm colonization start-up, COD load, C/N ratio, reflux ratio
