Abstract：Different feeding modes with different influent substrate concentration were investigated using anaerobic SBR, with the conditions of synthetic wastewater and real mature landfill leachate, respectively. The results showed that when treating low concentration of synthetic wastewater (NO2--N￡400mg/L), the feeding mode of 5min was a better choice for Anammox. When treating high concentration of synthetic wastewater (NO2--N3400mg/L), the continuous feeding mode of 5h was the best choice for Anammox. Under the continuous feeding mode of 5h, the average nitrogen removal rate (ANRR) increased to 39.11mgN/(gVSS·h) and enhanced by 40% comparing with the feeding mode of 5min.When treating the real mature landfill leachate with nitrite concentration of 300±20mg/L, ANRR of 5h was maximum comparing with other feeding modes. Because of the mature landfill leachate contained a little of biodegradable organics and lots of hazardous substances, the ANRR of treating mature landfill leachate was lower than that of treating synthetic wastewater.
