摘要： 研究了尿素(NS)、氯化铵(LA)、丙氨酸(BA)3种氮源对好氧颗粒污泥系统中的氮形态、污泥理化特性及微生物群落的影响。结果表明:LA组好氧颗粒污泥对溶解态氨氮去除率较低,NS组对总氮去除率最高;实验结束时(40 d),NS、LA、BA 3组污泥中的吸附态有机氮与吸附态氮的比值分别为73.28%、44.6%和77.3%,表明以氯化铵为氮源的污泥吸附态有机氮含量最低;好氧颗粒污泥胞外聚合物(EPS)中类色氨酸、辅酶F420峰荧光强度从大到小顺序为BA、NS、LA;在第40 d时BA组污泥亚硝酸盐氧化酶相对20 d时增加了91.8%,而NS和LA组分别增加了2.8%和40.8%,表明以氯化铵为氮源会提高污泥的亚硝酸盐氧化酶活性;微生物群落表明3组中优势菌均为Proteobacteria、Candidatus saccharibacteria、Bacteroidetes,以氯化铵为氮源的污泥Candidatus saccharibacteria丰度最高,丙氨酸的添加会增加脱氮细菌Proteobacteria、Bacteroidetes的丰度;京都基因与基因组百科全书(KEGG)二级通路图表明氨基酸代谢、碳水化合物代谢、膜运输为主要通路,其中BA组氨基酸代谢最高(13.11%)。总体而言,以丙氨酸为氮源的污泥脱氮性能更佳、脱氮功能菌丰度更高。

Abstract: The effects of urea (NS), ammonium chloride (LA) and alanine (BA) on nitrogen form, physical and chemical characteristics and microbial community of aerobic granular sludge were investigated. The results showed that LA group had less removal of dissolved ammonia nitrogen, while the total nitrogen removal rate was the highest in NS group. The ratio of adsorptive organic nitrogen to adsorptive nitrogen in NS, LA and BA groups were 73.28%, 44.6% and 77.3% at the end of the experiment (40 d), indicating that the content of organic nitrogen in the sludge adsorbed state with ammonium chloride as the nitrogen source was less; The fluorescence intensity of tryptophan-like and coenzyme F420 peak in theextracellular polymeric substances (EPS) of the sludge was BA＞NS＞LA. At the end of the experiment, the nitrite oxidase of BA group increased by 91.8%, while that of NS and LA group increased by 2.8% and 40.8%, indicating that the use of ammonium chloride as the nitrogen source increased the activity of nitrite oxidase in the sludge. Microbial community showed that the predominant bacteria in the three groups were Proteobacteria, Candidatus Saccharibacteria and Bacteroidetes at phylum level. The abundance of Candidatus Saccharibacteria using ammonium chloride as a nitrogen source was the highest. The addition of alanine could significantly increase the abundance of denitrifying bacteria Proteobacteria and Bacteroidetes, which was the lowest in the LA group, indicating that taking alanine as the nitrogen source could make the denitrifying bacteria accumulate well. Kyoto Encyclopedia of Genes and Genomes (KEGG) secondary pathway diagram showed that amino acid metabolism, carbohydrate metabolism and membrane transport were the main pathways, among which the amino acid metabolism of group BA was the highest (13.11%). In general, the sludge with alanine as the nitrogen source had better denitrification performance and higher denitrification functional bacteria abundance.
