摘　　要：通过连续试验和血清瓶批式试验研究了不同种类有机物对厌氧氨氧化耦合异养反硝化脱氮性能的影响.结果表明,从TN去除率来看,对耦合反应器的影响:苯甲酸钠<邻苯二酚<间苯二酚<丙酸钠<乙酸钠;苯甲酸钠、邻苯二酚、间苯二酚、丙酸钠和乙酸钠对厌氧氨氧化菌的影响很小.苯酚反硝化菌能利用苯甲酸钠、邻苯二酚、间苯二酚、丙酸钠和乙酸钠作为电子供体进行反硝化.不同有机物对苯酚反硝化菌的影响不同,进而影响苯酚反硝化菌与厌氧氨氧化菌之间的协同和竞争关系.苯甲酸是苯酚降解过程中可能的中间产物.The effect of different organic matters on nitrogen removal performance of anammox coupling heterotrophic denitrification process was investigated by continuous cultivation and serum bottle batch tests. In view of TN removal rate, the results showed that the sequence of these orgnic matters＇ influence on the coupling reactor was （from minimum to maximum）： sodium benzoate, o-dihydroxybenzene, m-dihydroxybenzene, sodium propionate, sodium acetate;, sodium benzoate, o-dihydroxybenzene, m-dihydroxybenzene, sodium propionate and sodium acetate have a little impact on the anaerobic ammonia oxidation bacteria. Phenol denitrifying bacteria could use sodium benzoate, o-dihydroxybenzene, m-dihydroxybenzene, sodium propionate and sodium acetate as electron donor for denitrification. Different organic matters had different influences on phenol denitrifying bacteria and then affected the cooperative and competitive relationship between phenol denitrifying bacteria and anaerobic ammonia oxidation bacteria. Benzoic acid was the possible product of nhenol degradation.
