the difference between grease trap and grease trap: \x1d\ grease trap is a kind of building structure, which has a good grease trap effect, but occupies a large area, and grease trap is a special equipment for separating impurities, oil and water from oily wastewater in restaurants. If the amount of sewage is particularly large, it will be better to use the grease trap, but if the amount of sewage is small, the installation of the grease trap is more convenient and convenient. \x1d\ The operation method of the oil separator can refer to its working principle: \x1d\ Oily wastewater flows into the oil separator box through the water inlet pipe, and coarse and large particles and residues are filtered by the mechanical grille installed at the water inlet of the oil separator, and the residues are discharged into the slag collecting barrel regularly for recycling; After the wastewater is baffled by the baffle device, it enters the oil gathering device. At the same time, the micro-bubble generator generates a large number of micro-bubbles. Due to the surface tension, the oil adheres to the micro-bubbles, and the oil particles change from small to large through the continuous collision of coalescence groups, thus accelerating the movement, so that oil and water with different specific gravity can be separated and layered, and the floating oil floats to the water surface. The floating oil is scraped to the oil collecting tank by the oil scraper, and then flows into the oil drum from the oil collecting pipe for recovery. After degreasing, the wastewater enters the water collecting tank and is discharged by the drainage pipe. The seal of the oil separator is fully sealed, and an air pipe is arranged on the oil separator, which is connected with the ventilation pipeline in the building to discharge the odor of wastewater outdoors; Vent pipes are provided to facilitate equipment maintenance. An overrunning pipe is arranged between the inlet and outlet pipes of the oil separator for draining water during equipment maintenance.
