The utility model discloses a system for separating leaked ammonia-containing wastewater and waste oil. The system comprises a liquid separator, a waste oil-water collection tank and a waste oil-water pump, wherein the ammonia-containing wastewater and lubricating oil leaked by an ammonia pump, an ammonium carbamate pump and other conveying equipment is led to a trench through an adapting pipe to be collected in the waste oil-water collection tank, and then is pumped from the waste oil-water collection tank to the liquid separator which is arranged at the position seven meters from the ground to be separated into oil and water phases; and the ammonia-containing wastewater with higher density enters an ammonia tank from a drainage pipe at the bottom of the liquid separator to be recycled to the system for utilization. The oil and water in the liquid separator are divided into an upper layer and a lower layer due to incompatibility, the ammonia-containing wastewater in the lower layer flows from a water outlet pipe to the ammonia tank and enters the system; the lubricating oil in the upper layer flows from an overflow pipe to a waste oil-water tank and is conveyed to an industrial waste water treatment system through a waste oil-water pump.
