Abstract

Three different control methods based on oxidation reduction potential (ORP) and dissolved oxygen (DO) for determining aeration time were evaluated for swine wastewater treatment at full-scale SBR. For determining the Ending Point of Ammonia Oxidation (EPAO), the plateau in ORP profile, the derivative of DO, and absolute DO were tested. Below 0.5 kg NH4_x000D_ +-N/m3·day of influent loading rate, three control methods produced good results; however, above this loading rate, only absolute DO method was feasible. The volumetric ammonia nitrogen load at the sub-cycle (Kg NH4 +-N/m3/sub-cycle) had an effect on the period of aeration. To put it more concretely, the higher loading rate required a longer ammonia nitrogen oxidation period. To estimate nitrogen load, the length of low DO period, which was defined as the required time to reach 3 mg DO/l from the start of aeration, was the most proper parameter.
