Abstract: The application of A/A/O microporous aeration oxidation ditch process to the treatment of municipal sewage containing coal slurry in northern cold climate regions is presented. The actual operation results show that the adopted process can fortify the effect on the removal of nitrogen and phosphorus. When the climate environment temperature is low and the influent conditions vary, this process has pretty high removing effect on pollutants. Furthermore, it runs steadily, meeting the designed target requirements.
