The upflow biological aerated filter(UBAF) filled with grain slag was applied in Yellow River treatment. The aim is to study the reactor’s ability withstanding ammonia nitrogen volumetric loading in Yellow River water treatment. As influent NH4+-N concentration increases from 0.2mg/L to 3.0mg/L, the average removal rate of turbidity, CODMn and NH4+-N were 82%, 27% and 97% respectively, and removal of NH4+-N occurs mainly in the filter layer depth changing from 150cm to 210cm. The nitrification performance improves when PO43- -P concentration in water reach 60μg/L, and the removal of NH4+-N occurs mainly in the filter media layer depth shortened from 210cm to 90cm.
