Grey water residue removal and oil separation device

Abstract

The invention discloses a grey water residue removal and oil separation device which comprises a shell body (1). A water inlet (2) and a water outlet (8) are arranged on the shell body (1); a collecting chamber (6), a dividing chamber (4), an oil collecting chamber (13) and a clean water chamber (5) are arranged in the shell body (1) in sequence; the water inlet (2) is communicated with the collecting chamber (6); a residue collector (3) is arranged at the water inlet position of the water inlet (2); the collecting chamber (6) is communicated with the dividing chamber (4); after entering from the water inlet (2), grey water firstly reaches the collecting chamber (6) through the residue collector (3) and then reaches the dividing chamber (4); the upper part of the dividing chamber (4) is communicated with the oil collecting chamber (13), and the bottom part of the dividing chamber (4) is communicated with the clean water chamber (5); and the water outlet (8) is communicated with the clean water chamber (5). The grey water residue removal and oil separation device is simple in structure, has low processing cost, is convenient to operate and can completely filter and remove suspended residues in the kitchen grey water and efficiently separate various oil ingredients in the grey water.

Description

technical field [0001] The invention relates to a gray water slag removal and oil separation device. Background technique [0002] Ship galley gray water refers to the sewage containing animal and vegetable oil products produced in ship galleys, dining rooms, tableware washing rooms and other cabins. In the past, due to domestic and foreign environmental protection regulations, there were no treatment requirements for ship galley gray water, and it was generally discharged directly. With the strengthening of the awareness of global marine environmental protection, this issue has attracted more and more attention. The composition of ship galley gray water is complex, with high organic content, mainly including animal and vegetable oils, dietary fiber, starch, fat, various condiments, detergents, proteins, and suspended residues of animals and plants. Pollutants in kitchen gray water mainly exist in the form of colloids, which have the characteristics of high SS, BOD, and COD...

AI Technical Summary

Problems solved by technology

Grease-clogged pipes are very difficult to unclog

If a membrane bioreactor is used to treat kitchen gray water, the oil will cause membrane pollution

After the ship galley gray water is discharged into the water, an oil film will form on the water surface, which will affect the oxygen exchange between the air and the water body and reduce the reoxygenation rate
