%X A study on nitrification of low NH+4-N concentration sewage was performed in continuous flow biofilm reactor by controlling the pH,dissolved oxygen(DO) and hydraulic retention time(HRT).The results showed that under the conditions of temperature of 34℃,the influent ammonia concentration of 35~45 mg/L,dissolved oxygen of 1.4~1.5 mg/L,pH of 8.3 and hydraulic retention time of 8 h,both NH+4-N removal efficiency and nitrite accumulation efficiency could reach about 80%.The better-efficiency removal of NH+4-N and stable accumulation of nitrite can be achieved.
