| 摘 要： | 采用包埋固定化活性污泥法进行污水深度处理脱氮,针对不同初始总氮浓度的模拟废水,基于序批式间歇反应器的小试实验,探讨了包埋颗粒的脱氮效果及其微生物种群特性.结果表明,在包埋颗粒的体积投加率为10%,实验水温为10~15℃,DO为2~4 mg·L~(-1)和初始COD浓度为80~100 mg·L~(-1)条件下,不同初始总氮浓度(10~45 mg·L~(-1))和C/N比(1.78~10)的各反应器中,稳定期包埋颗粒的最大总氮去除负荷为7.78~23.18 mg·(L·h)~(-1).扫描电镜发现,包埋颗粒具有较好的孔隙结构,且颗粒内部与表面均存在微生物附着生长,已成为微生物的良好载体.高通量测序结果表明,较初始包埋污泥,包埋颗粒内部与表面的微生物群落构成发生了显著变化,包埋颗粒内微生物多样性良好,颗粒中脱氮菌属优势明显.包埋颗粒中存在异养硝化-好氧反硝化菌属,提升了包埋颗粒内非传统生物脱氮途径的潜能.
