  • 摘要: 雨污混流农村污水具有低污染、低碳氮比的特性,由于碳源缺乏导致其采用生物法处理时总氮(TN)难以去除,无法达标排放。采用芦竹碎段作为缺氧/好氧(A/O)生物滤池(2#)缺氧段填料和碳源强化对农村污水脱氮,以砾石A/O生物滤池(1#)作为对照组,研究芦竹对氮的强化去除作用,并采用扫描电镜(SEM)和实时荧光定量聚合酶链式反应(qPCR)分析生物滤池中的脱氮微生物群落。结果表明:当进水CODCr NH 4 + -N、TN和 PO 4 3 - -P浓度分别为(79.47±14.21)、(34.49±2.08)、(34.73±3.87)和(2.38±0.46)mg/L,水力停留时间为10 h时,1#和2#生物滤池对其去除率分别为88%±7%和86%±6%、90%±2%和97%±7%、38%±13%和65%±9%、27%±13%和40%±18%。芦竹作为缺氧段填料能显著增强A/O滤池对 NH 4 + -N、TN和 PO 4 3 - -P的去除效果。1#和2#生物滤池缺氧段填料上的微生物均以短杆菌为主;2#生物滤池缺氧段中微生物反硝化脱氮和厌氧氨氧化(ANAMMOX)功能基因丰度高于1#生物滤池。
    Abstract: Rural sewage mixed with rainwater always has the characteristics of low pollution and low carbon-nitrogen ratio. Due to the lack of carbon source, the total nitrogen (TN) is difficult to remove and cannot meet the discharge value when rural sewage is treated by biological method. The broken Arundo donax pieces were used as the filter media and carbon source for the anoxic column of the anoxic/oxic (A/O) biofilter (2 #) to enhance the nitrogen removal for rural sewage, and the gravel-filling A/O biofilter (1#) was set up as the control, in order to study the nitrogen removal enhancement of Arundo donax. The denitrifying microbial communities in the system were also analyzed by the scanning electron microscopy (SEM) and real-time fluorescence quantitative polymerase chain reaction (qPCR). The results showed: when the influent CODCr, ammonium ( NH 4 + -N), TN and phosphate ( PO 4 3 - -P) concentrations were (79.47±14.21), (34.49±2.08), (34.73±3.87)and (2.38±0.46) mg/L, respectively, their removal rates of 1# and 2# biofilters were 88%±7% and 86%±6%, 90%±2% and 97%±7%, 38%±13% and 65%±9%, 27%±13% and 40%±18% , respectively, at the 10 h hydraulic retention time. The biofilter with Arundo donax as the anoxic column filter media could significantly enhance the removal rates of NH 4 + -N, TN and PO 4 3 -P of A/O biofilter. The microorganisms on 1# and 2# biofilters anoxic column medias were mainly composed of short bacilli, and the abundance of denitrification genes and anaerobic ammonium oxidation (ANAMMOX) genes in 2# anoxic column was higher than those in 1# anoxic column.
