The invention discloses a waste water pretreatment device for food processing industry, which belongs to the technical field of food processing waste water treatment. The wastewater pretreatment device includes a filter mechanism, which includes a water passage and a filter screen; a separation tower of the oil-water separation mechanism is arranged in the outer shell, and the separation tower includes a tower-shaped skeleton and an oil-water separation membrane, and the tower-shaped skeleton includes an upwardly convex On the water-facing surface, there are a plurality of horn-shaped support frames at the bottom, each of which is a structure with a small top and a large bottom, and the dimensions of the plurality of horn-shaped supports increase layer by layer from top to bottom; The racks are connected by the outwardly inclined supporting inclined rods; the oil-water separation membrane is covered on the outside of the horn-shaped support frame and the supporting inclined rods; the storage devices are respectively used to receive the separation liquid on both sides of the oil-water separation membrane. The wastewater pretreatment device of the invention can not only well realize the pretreatment of food processing wastewater, but also saves energy and protects the environment, and has good treatment effect.
Description
technical field [0001] The invention relates to the technical field of food processing wastewater treatment, in particular to a wastewater pretreatment device in the food processing industry. Background technique [0002] The food industry has a wide range of raw materials and a wide variety of products. A large amount of water is used in the processing process. Therefore, a lot of waste water will be generated and discharged in the form of sewage. The amount of discharged waste water is large, and the water quality is obviously different. The waste water in the food processing industry is mainly floating solids. Substances, oil, protein, starch, colloid or sediment suspended in wastewater; [0003] Wastewater pretreatment in the food processing industry is a pretreatment facility set up according to the water quality requirements of the subsequent treatment process before the wastewater enters traditional sedimentation and biological treatment. At present, the existing pret...
