Abstract

The invention discloses a food waste oil removing treatment method. Water-containing food waste is sequentially subjected to flocculation pretreatment, a buffer tank, a micro-bubble gas oil spill absorption device, an oil catalysis, re-solution and absorption reactor, a pH regulation tank, a primary sedimentation tank, an organic rhodium catalytic-reaction tank, a biological denitrification tank, a secondary sedimentation tank and a clear water tank. The method creatively utilizes the oil molecule catalysis action of a pi-allyl nickel compound, when the oil in wastewater is adsorbed by modified diatomite and is at the temperature of 200-250 DEG C, the C-H bonds in the oil molecules can transiently break under the catalysis action of the pi-allyl nickel compound and are rapidly recombined into C-C bonds or C-H bonds, the C-H bonds break again, while the C-C bonds do not break again due to the limited catalysis action of the pi-allyl nickel compound. Therefore, oil molecules shorter in carbon chain can be gradually synthesized into heavy oil molecules longer in carbon chain.
