| 摘 要： | 基于ABR-MBR一体化反应器,以低C/N比生活污水为研究对象,结合厌氧折流板反应器(ABR)微生物相分离的特性,通过优化与ABR优质供碳和脱氮除磷相耦合的膜生物反应器(MBR)硝化液回流比以实现高效反硝化除磷,并对ABR-MBR污泥回流比进行优化.结果表明,在ABR段有机负荷为2.0 kg·(m3·d)-1、系统的水力停留时间(HRT)为9 h、泥龄(SRT)为15 d,系统获得最优的处理效果时的硝化液回流比和污泥回流比分别为300%和100%.其中TN和溶解性PO3-4-P平均去除率分别达84%和94%,ABR中反硝化除磷量可达系统总去除量的87%,平均出水TN和溶解性PO3-4-P浓度分别为12.98 mg·L-1和0.43 mg·L-1.

| Abstract: | An integrated process based on combination of the anaerobic baffled reactor(ABR)-membrane bioreactor(MBR) was adopted to treat domestic sewage with low C/N ratio. In order to realize the function of highly efficient denitrifying phosphorus removal, nitrate recycling ratio and sludge recycle ratio were optimized in this study. The results indicated that the optimized denitrifying phosphorus removal efficiency was achieved under the conditions of organic loading rate of 2.0 kg·(m3·d)-1 in ABR, total hydraulic retention time (HRT) of ABR-MBR at 9 h, the SRT at 15 d, sludge reflux ratio of 100%, and nitrate recycling ratios set to 300%. The average removal rates of TN and soluble PO43--P were 84% and 94%, the amount of phosphorus removed by denitrifying accounted for 87% of the total phosphorus removed, and the average effluent concentration for TN and soluble phosphorus were 12.98 mg·L-1 and 0.43 mg·L-1 respectively. |
