The invention provides an oil-water separation device and application. Oil-water separation pipelines are arranged in a three-dimensional space according to a extended-range time delay principle; through layer-by-layer gravity sedimentation, water and oil in crude oil production liquid or oil-containing sewage are separated, thereby achieving a good oil-water separation effect; whether for a pre-separation, coarse separation or fine separation process, the effect of almost no oil in discharged liquid discharged from a water outlet pipe at the bottom of a pipe body can be achieved; the discharged liquid can directly enter a gravity settling tank or other processes through branch pipelines for further separation; and the water contained in the oil discharged from an oil outlet in the top ofthe pipe body can be reduced to less than 20%.

The invention discloses a garbage sorting and screening mechanism of an automatic sorting processor for kitchen wastes, in particular to the technical field of sorting and screening of the kitchen wastes. The garbage sorting and screening mechanism comprises a box body and an oily water collection box, wherein a water drain plate is horizontally and fixedly connected to the interior of the box body; reserved holes are formed in the water drain plate; and the oily water collection box is arranged at the bottom end of the water drain plate and is positioned in the box body. According to the garbage sorting and screening mechanism disclosed by the invention, through arrangement of a driving motor, rotary shafts, a frame body, a screening box, clamping slots, a cover plate, a handle and fixed blocks, the cover plate is opened, garbage is poured into the screening box, and then the fixed blocks are embedded in the clamping slots; the driving motor is started, the rotary shafts are driven through a driving shaft to be rotated; and because round holes are formed in the screening box, oily water and small solid garbage can be screened to the bottom of the screening box in a rotation process of the screening box, so that large solid garbage can be remained in the screening box, and therefore, the screening effect is better, the screening efficiency is higher, and the oily water can be conveniently separated from the solid garbage.

The invention discloses a method for preparing feed ingredients from kitchen wastes. The method comprises the following steps: (1) solid-liquid separation: performing solid-liquid separation on the kitchen wastes through a filter device, performing oil-water separation treatment on liquid obtained by solid-liquid separation, and performing solid-solid separation on a solid mixture obtained by solid-liquid separation, wherein the solid mixture contains plastic products, metal products and food residues at the same time; (2) solid-solid separation: putting the plastic products and the metal products which are subjected to separation into the solid kitchen waste retreatment procedure, and putting the separated solid food residues into the dehydration treatment procedure; (3) dehydration treatment procedure: dehydrating and deoiling the solid food residues until the moisture content is below 60 percent, putting the treated solid food residues into the drying treatment procedure, and performing oil-water separation treatment on liquid collected by squeezing; (4) drying treatment procedure: drying the solid food residues at high temperature to obtain the feed ingredients. The process is simple and controllable; the industrial chain of production is complete, so that the problem of incomplete treatment is solved.

The invention discloses a full-section overflowing mechanism of a restaurant wastewater pre-treatment device and a full-section overflowing method. The full-section overflowing mechanism comprises a machine case and a plurality of separation plates mounted in the machine case, wherein the plurality of separation plates comprise three full-section separation plates; two opposite side edges of the first full-section separation plate are fixed at two opposite sides of the machine case respectively and are vertically arranged above a bottom plate of the machine case; a transverse flow channel I isformed between the lower end of the first full-section separation plate and the bottom plate and the upper end of the first full-section separation plate is not in contact with a top plate of the machine case, so that the machine case is divided into an oil-water separation region and a liquid discharging region, which pass through the transverse flow channel I and are mutually communicated; thesecond full-section separation plate is located in the liquid discharging region; the upper end of the second full-section separation plate is fixed on the top plate and the lower end of the second full-section separation plate is not in contact with the bottom plate; meanwhile, a transverse flow channel II is formed between the upper end of the second full-section separation plate and the bottomplate; the lower end of the third full-section separation plate is vertically fixed on the bottom plate, and a vertical flow channel capable of enabling liquid to flow out from the upper end of the third full-section separation plate under the action of static pressure is formed by the lower end of the third full-section separation plate, the second full-section separation plate and the machine case.

The invention discloses a preparation method of an oil-water separation membrane, and belongs to the technical field of environmental protection. According to the method, wood stone fiber is mixedintopolyvinylidene chloride melt in a suitable temperature condition, and lignin reaches glassy state, is softened and flows under high pressure; nanofiber sponge is prepared from resin soaked activatedstone pulp; sea-foam stone powder in the activated stone pulp belongs to a magnesium-enriched silicate compound, can magnesium hydroxide crystal and ammonium phosphate under the action of ammonia gasand phosphoric acid, not only ensures that oil absorption sponge has high porosity, but also ensures that the oil absorption sponge has certain flame retardant property; firstly scale has a bionic hydrophobic structure, and a separation membrane structure with a hydrophobic exterior; finally during the process of copper film plating, the internal surface area of fiber fabric is greatly increased through activation of phosphoric acid, and a plurality of active centers are formed in the surface of the fiber fabric; granule suspension oil and dissolved oil liquid can be easily absorbed into interiors of pores, so that damage to the inner surface of the fiber sponge is weakened when the inner surface is scoured by liquid, and the oil-water separation membrane has a wide application prospect.
