description The invention relates to an oily food sewage treatment system and method. The oily food sewage treatment system and method comprises a collecting tank, an oil-water separating treating pond, an oil extracting mechanism, an oil collecting barrel, a nitrification-denitrification treating pond, a pressure filter and a Roots blower, wherein the collecting tank performs primary filtering on sewage, theoil-water separating treating pond internally completes oil-water separation, the oil extracting mechanism scrapes and collects a floating oil layer into an oil collecting barrel, flocculating agentand pH regulator are added to improve the water quality of the sewage to remove CODcr (chemical oxygen demand chromium), SS (suspended solid) and chroma, the nitrification-denitrification treating pond removes organic pollutants from the sewage to ensure that water produced through treatment can meet standards on recycling of non-drinking water, and the pressure filter can timely discharge and press residual activated slud
