| 摘 要： | 为研究不同进水碳氮比对缺氧/好氧SBR亚硝化系统的影响,在室温下(18～20℃),调节进水的碳氮比为0,2/3,1,4/3,2,3,6,对反应器的运行情况进行研究.结果表明:在进水COD和氨氮负荷分别为0. 2,0. 3 kg/(m~3·d)时,仅历经24 d就成功获得了亚硝化絮状污泥,比进水无COD的污泥系统能较快启动亚硝化工艺.在碳氮比小于6时,污泥系统均能保持良好的亚硝化性能,亚硝化率大于90%;碳氮比为6时,亚硝化率下降至70%.进水碳氮比为4/3时,异养菌充分利用进水COD进行脱氮,总氮的去除率达到49. 8%,且COD的去除率保持在80%以上;进水碳氮比小于4/3时,污泥系统缺乏碳源,总氮去除率随着碳氮比的增加而增加;当碳氮比为4/3～2时,COD和总氮去除率几乎没有变化;当碳氮比为2～6时,由于进水氨氮负荷的降低,COD和总氮的去除率呈下降趋势,运行末期(154 d),COD和总氮的去除率分别为64. 8%,18%.由COD的增加而引起碳氮比的增加时,蛋白质(PN)呈逐渐增加的趋势,多糖(PS)几乎不变,而由氨氮的减少引起碳氮比的增加,PN和PS均下降,但PN与PS比呈上升趋势.
