好氧硝化污泥启动厌氧氨氧化试验研究

Study on the Anammox Treatment Cultivated by Aerobic Nitrification Sludge

以好氧硝化污泥为培养污泥,采用经稀释的猪场废水启动厌氧氨氧化反应器,经过125 d的培养,根据ASBR反应器出水水样监测结果显示:ASBR反应器稳定运行后NH4+-N、NO2--N的去除率分别达到91.7%、92.0%,说明采用ASBR反应器,接种好氧硝化污泥可成功启动厌氧氨氧化反应器,验证了利用厌氧氨氧化工艺处理类似养殖废水的高氨氮废水的可能性。

Taking anaerobic nitrification sludge as inoculating sludge,the start-up of anammox reactor is adopted to treat the diluted piggery waste water,the ASBR reactor output water after 125 days operation showed the removal rates of NH4^ ＋-N, NO2^--N for ASBR reached 91.7 %, 92.0% respatively. It indicated that with anaerobic nitrification sludge, anammox reaetor was started successfully by ASBR reactor. The results indicated the possibility of anammox for treating the high strength ammonia waste water like piggery waste water.
