摘要:異化硝酸鹽還原為銨（DNRA）是全球氮循環(huán)中不可缺少的部分，但目前關(guān)于污水處理系統(tǒng)中DNRA的研究較少。為此，以乙酸鈉、葡萄糖和無水乙醇等比例混合碳源為底物，采用兩個(gè)相同的ASBR反應(yīng)器（分別代表生物膜系統(tǒng)和活性污泥系統(tǒng)），考察不同污泥形態(tài)及進(jìn)水方式對(duì)DNRA菌富集及產(chǎn)銨性能的影響。結(jié)果表明，經(jīng)過145 d的馴化培養(yǎng)，兩套反應(yīng)器均具備一定產(chǎn)銨能力且成功富集出DNRA菌，平均產(chǎn)銨率分別為15.08%和3.34%，屬水平上DNRA菌占比分別為4.66%和3.37%，其中優(yōu)勢(shì)菌屬均為Desulfobulbus。對(duì)比發(fā)現(xiàn)，當(dāng)進(jìn)水方式為間歇流時(shí)，兩個(gè)系統(tǒng)的產(chǎn)銨率相當(dāng)且均低于5%；而將生物膜反應(yīng)器進(jìn)水方式改為連續(xù)流，運(yùn)行穩(wěn)定后系統(tǒng)的產(chǎn)銨率最高可達(dá)到16.57%，遠(yuǎn)遠(yuǎn)高于活性污泥系統(tǒng)，說明連續(xù)流更有利于DNRA菌產(chǎn)銨。
Abstract:Dissimilatory nitrate reduction to ammonium (DNRA) constitutes an essential component of the global nitrogen cycle. However, limited research has been conducted on DNRA within wastewater treatment systems. In this study, sodium acetate, glucose, and anhydrous ethanol were utilized as substrates, and two identical anaerobic sequencing batch reactors (ASBR), biofilm system and activated sludge system, were employed to investigate the effects of different sludge forms and influent modes on the enrichment and ammonium production of DNRA bacteria. Following 145 days of acclimation and cultivation, both reactors achieved certain capability in ammonium production and successfully enriched DNRA bacteria. The average ammonium production rates were 15.08% and 3.34%, respectively. At the genus level, the proportions of DNRA bacteria were 4.66% and 3.37%, respectively. Desulfobulbus was identified as the predominant bacterial genus. When the reactors were operated in intermittent flow, the ammonium yield in both systems was comparable and remained below 5%. However, upon switching the inflow mode of the biofilm reactor to continuous flow, the system achieved a maximum ammonium production rate of 16.57% after reaching stable operation， which was significantly higher than that of the activated sludge system, suggesting that continuous flow was more favorable for ammonium production by DNRA bacteria.
