The experiment used micro-pressure swirl reactor (MPSR) as the object to investigate removal of pollutants and distribution of dissolved oxygen (DO). The results show that the average removal rates of chemical oxygen demand (COD), ammonia nitrogen (NH 4 + -N), total phosphorus (TP) and total nitrogen (TN) were 92.4%, 98.6%, 98.0% and 73.8%, respectively. In aeration stage, DO at outlet and central points was obviously different, and the anoxic and aerobic zones were formed naturally. Such as Spirostomum, Macrobiotus and Amphileptus observed during microbiological examination, which indicates a good operating state in MPSR.
