Description

Technical Field

Background

A large amount of animal grease and vegetable grease exist in the kitchen waste water, the grease can be recycled as raw materials of products such as biodiesel and oleic acid, and the kitchen waste water is a usable renewable resource. In the prior art, oil and fat in kitchen wastewater are generally recycled after oil-water separation, and the oil and fat removal from the wastewater generally adopts a coarse graining separation method, an air flotation separation method, a filter element filtration method, an activated carbon filtration method and the like, but the methods pay attention to how to completely separate oil and water, and the efficiency of the oil-water separation is not very good. In the prior art, for example, patent document 1 (CN 103754984A) discloses an oil-water separation device for kitchen wastewater, which introduces wastewater into an oil-water separation tank at the lower end, and then sets a hydrophobic oleophilic mesh layer at the upper end to separate oil, although oil-water separation is realized, the oil-water separation efficiency is not high, and grease floats to the upper surface due to the influence of gravity; for another example, patent document 2 (CN 102225794B) discloses a combined oil-water separation device and method for kitchen waste wastewater, which includes disposing several spindle coalescence-transmission layers in a cone shape, so that oil droplets are gathered by the spindle coalescence-transmission layers and then collected to an oil-water separation membrane for coalescence, and then excess water is removed through an oil-water separation membrane layer to achieve oil-water separation and achieve the purpose of filtering wastewater; as further disclosed in patent document 3 (CN 102659258B), a method and a device for processing kitchen swill are disclosed, wherein swill is installed in a container, and an oil absorbing transmission belt is installed, oil is absorbed by the oil absorbing transmission belt, and then oil is extruded by an extrusion wheel, so as to achieve the purpose of oil-water separation, although oil-water separation is achieved in this way, the transmission belt needs to pass through a plurality of pulleys, so that grease in the oil absorbing transmission belt is easily returned to the container, and meanwhile, the oil-water separation device is fixed, and can achieve oil-water separation only passively waiting for grease to approach the transmission belt, which undoubtedly also reduces the efficiency of oil-water separation; finally, as disclosed in patent document 4 (CN 114772773A), an adaptive oil-water separation device is disclosed, which uses an air flotation separation method to separate oil from water, and the diameter of bubbles introduced into the separation device is changed to achieve a better oil-water separation effect, but it does not improve the oil-water separation efficiency.

In summary, in the prior art, for the treatment of kitchen wastewater, oil and water separation is realized by automatically floating oil and fat on the water surface, although oil and water separation is realized by wrapping oil and fat with bubbles by using an air floatation method or rising after grease is adhered to the outside of bubbles, oil and water separation is realized by using the buoyancy of gas or oil, because oil or bubbles are light and have slow floating speed, the efficiency of oil and water separation is seriously influenced, and further the filtering efficiency of the kitchen wastewater is not high.
