Abstract

The effect of DO on phosphorus removal was investigated by using Orbal oxidation ditch process. The results show that the anaerobic environment was formed in the area below the longitudinal 1.5m of the outer ditch, which was beneficial to the full release of phosphorus from the polyphosphate bacteria. In the middle ditch and the inner ditch adopt the traditional design and operation mode,when the DO concentration was kept at 1 mg.L-1 and 2 mg.L-1, the phosphorus accumulating bacteria had good phosphorus accumulation effect, and the average total phosphorus of the oxidation ditch effluence was stable at 0.14 mg.L-1.
