Description

Energy-saving oil-water separation device Technical Field The utility model relates to the technical field of sewage pretreatment, in particular to an energy-saving oil-water separation device. Background Municipal wastewater treatment is a critical ring in the process of urbanization, wherein an oil-water separation device plays a key role. Along with the increasing of the urban speed, the oil content in the wastewater in the fields of catering, industry and the like is increased increasingly, and higher requirements are put on the oil-water separation technology. In the technical background, the municipal sewage oil-water separation device mainly adopts methods such as gravity separation, centrifugal separation, cyclone separation and the like. The device can effectively separate oil stains from the wastewater, and reduce pollution to water. For example, the Monk oil-water separator adopts an eddy sedimentation separation method, and utilizes centrifugal force generated by different specific gravities of three oils, water and mud in restaurant sewage to realize rapid and efficient separation.
