Abstract
The invention discloses an oily sewage treatment system. A mechanical grill is arranged at the entrance of the regulating pool, and the sewage in the regulating pool is lifted to a cyclone degreaser through a lifting pump, so that oil and water are naturally separated under the action of centrifugal force. Then the sewage enters the air flotation device, and then enters the oil-water separator to filter the oil pollution above 10 microns, and then enters the precision filter through the activated carbon filter, filters the oil pollution above 5 microns, and then goes through the anoxic pool for anaerobic nitrification reaction, and then passes through the membrane The biological reaction tank is oxidized and decomposed to meet the discharge standard. The invention adopts two-stage filtration to treat sewage with high oil content, and then conducts conventional sewage treatment. The invention has high pollutant removal efficiency, strong nitrification ability, stable water quality, low residual sludge output, compact equipment and simple operation. .
