【摘要】 以人工配制的含氮废水为研究对象,通过控制反应器内废水的pH>8.48、碱度>1 439 mg/L、DO<0.1 mg/L、氨氮容积负荷为0.27 kg/(m3.d),在长污泥龄(106 d)活性污泥亚硝化系统中成功实现了反应器出水NH4+-N与NO-2-N的浓度比例接近1∶1的稳定亚硝化积累结果,为早日能够运用亚硝化/厌氧氨氧化生物脱氮工艺实现高效生物脱氮提供了科学依据。更多还原

【Abstract】 Taking synthetic nitrogen-containing wastewater as research object,through controlling pH at above 8.48,alkalinity at above 1 439 mg/L,dissolved oxygen at below 0.1 mg/L and volumetric loading of NH+4-N at 0.27 kg/(m3·d),a stable nitrosation accumulation with NH+4-N/NO-2-N ratio of 1 ∶1 in the effluent of the reactor was successfully realized in the long sludge age(106 d) nitrosation system,which provides the precondition for realizing high efficient biological nitrogen removal in anaerobic ammonium oxidation process.更多还原
