| 摘 要： | 在SBR中接种普通好氧活性污泥,通过控制运行条件来实现短程硝化,同时提高厌氧生物转盘系统中厌氧氨氧化的氮负荷,使之与SBR出水中NO2--N的积累量相匹配,并将二者组合形成短程硝化/厌氧氨氧化自养脱氮工艺.处理含氨废水的试验结果表明:在SBR的进水NH4+-N为150～250 mg/L、温度为(28±2)℃、pH值为7～8、DO<1 mg/L的条件下,可实现稳定的短程硝化,NO2--N积累率达85%以上,NH4+-N负荷达0.129 kgN/(kgVSS·d),AOB和NOB的数量之比为103:1.将短程硝化出水加入NH4+-N后作为厌氧氨氧化反应器的进水,在(40±1)℃下可以达到自养脱氮的目的,对NH4+-N、NO2--N和TN的去除率分别达86%、97%和90%以上,TN容积负荷为0.488 kgN/(m3·d).

| Abstract: | The single reactor high activity ammonia removal over nitrite(SHARON) process was achieved by inoculating common aerobic sludge and controlling the operation conditions in a sequencing batch reactor(SBR),and the nitrogen loading rate of anaerobic ammonium oxidation(ANAMMOX) in a anaerobic rotating biological contactor was improved in order to match the accumulative quantity of NO-2-N in the effluent of SBR.The SHARON process and ANAMMOX process were combined to treat ammonia-containing wastewater.The result... |
