英文摘要Optimization of running parameters in a bioreactor requires detailed understanding of microbial community dynamics during the startup and running periods. using a novel piggery wastewater treatment system termed "uasb + sharon + anammox" constructed in our laboratory, we investigated microbial community dynamics using the illumina miseq method, taking activated sludge samples at similar to 2-week intervals during a similar to 300-day period. ammonia-oxidizing bacteria (aob) were further investigated by quantification of aob amoa genes and construction of gene clone libraries. major changes in bacterial community composition and dynamics occurred when running manner was changed from continuous flow manner (cfm) to sequencing batch manner (sbm), and when effluent from an upflow anaerobic sludge blanket (uasb) reactor for practical treatment of real piggery wastewater was used as influent; differences among these three experimental groups were significant (r-2 = 0.94, p < 0.01). when running manner was changed from cfm to sbm, relative abundance of the genus nitrospira decreased sharply from 18.1 % on day 116 to 1.5 % on day 130, and to undetectable level thereafter. relative abundance of the genus nitrosomonas increased from similar to 0.67 % during the cfm period to 8.0 % by day 220, and thereafter decreased to a near-constant similar to 1.6 %. environmental factors such as load ammonia, effluent ammonia, effluent nitrite, uasb effluent, ph, and do levels collectively drove bacterial community dynamics and contributed to maintenance of effluent nh4+-n/no2--n ratio similar to 1. theses results might provide useful clues for the control of the startup processes and maintaining high efficiency of such bioreactors.
