纳米活性碳纤维SBR法处理生活污水的试验研究

在SBR反应器中安装纳米活性碳纤维处理生活污水,进行正常负荷与有机冲击负荷的对比试验,并对生物相进行追踪观察.结果表明：正常负荷运行时,生物膜上的微生物种类多、活性大;出水COD去除率均在90%以上;NH3—N和TP去除率分别在95%以上和72%～85.5%之间,均能达到城镇污水处理厂污染物排放标准（GB18918-2002）中一级A标准要求.系统抗有机冲击负荷的能力强,在提高进水COD浓度3～4倍的情况下,去除率仍保持在86%以上;有机冲击负荷对脱氮效果影响较小,对总磷的去除率下降幅度较大.

Experimental Research on Treatment of Domestic Sewage by Nano Carbon Fiber SBR Process

Experiments of normal load and high impact load on domestic sewage treatment by nano carbon fiber in SBR reactor were conducted comparatively and biological phase was tracked and observed.Experimental results show:in the normal load operation,microbes had more in kinds and bigger activity in biological membrane;the removal rate of COD was over 90%,and those of NH3—N and TP were over 95%and 72%~85.5% respectively,so they can meet the requirements of urban sewage treatment plants for pollutants discharge(GB18918-2002) in A standard.The system was strong in its resistance to high impact load.When COD concentration in water was increased to 3~4 times,its removal rate remained over 86%.High impact load had less effect on removing nitrogen,but the removal rate of phosphorus declined greatly.
