Oil separation tank with dissolved air release function

Abstract

The invention discloses an oil separation tank with a dissolved air release function. A dissolved air release port and a dissolved air water pipeline are designed in the oil separation tank; the oil separation tank can separate and remove suspended oil on the surface of sewage; waste water and gas can form microbubbles, and oil and particles deeply dissolved in the water are separated from the water under the action of the microbubbles and float on the water surface; the oil and particles suspended on the water surface are collected through an oil collecting pipe system, the oil separation effect is more obvious, and operation is more convenient and faster; a nano oil-water separation membrane is arranged in a third compartment, and clear water can be further filtered and separated; an oilguide pipe is arranged in the third compartment, oil absorption treatment can be further conducted on the clear water separated out by the nano oil-water separation membrane, and thus it can be guaranteed that residual oil in the clear water is separated from water.

Description

technical field [0001] The invention relates to a grease trap, in particular to a grease trap with dissolved air release. Background technique [0002] Existing ordinary oil separation treatment equipment, set baffles in the pool to divide the pool body into several grids, when oily wastewater passes through each grid pool, part of the oil is blocked by the baffles, and then enters the next level of grid tank to treat the wastewater Do similar processing, there are no other settings inside it. [0003] Each cell of the grease trap only acts as a barrier to the waste water, and uses the difference in specific gravity between oil and water to separate and remove the suspended oil with larger particles in the sewage. However, the treatment effect on the oil dissolved in the waste water is poor, and only It is difficult to treat the oil suspended on the water surface, and it is difficult to treat the oil dissolved in water, and it can only be manually salvaged for suspended oil...
