The invention relates to a method and a device for strengthening oil-water separation and coupled desalting functions in a cold low pressure separator. The method comprises the following steps: performing countercurrent mixing on water-containing low-content oil and desalted water with the volume ratio of 0-1 percent at the inlet section, allowing the mixture to enter a T-shaped liquid-gas separator for being subjected to degassing treatment, rapidly separating the gas phase subjected to step-down flash in the low-content oil, and allowing the oil-water mixture to flow to a rectification distributor on the lower part of the low-pressure separator from a left seal head to a right seal head so as to realize uniform distribution on the radial section; rapidly separating the oil water by virtue of a coarse graining module and a CPI module sequentially, discharging one part of water, allowing oil and trace water (0-0.01 percent) to enter a deep separation section by virtue of a separator, performing deep dehydration on the oil by virtue of a fiber combined module, discharging the oil, performing further deep deoiling on the intercepted water by virtue of the combined fiber module, and discharging the water. According to the method and the device disclosed by the invention, the oil-water separation performance of the cold low pressure separator can be strengthened, the desalting function in the oil can be realized, the occupied area of the low pressure separator is reduced, and the defects of the conventional low pressure separator are overcome.

The invention discloses a crude oil electric desalination dehydrator used in the petrochemical industry, in order to solve the problems existing in the existing electric desalination dehydrator that adopt a weak electric field to feed materials, which weakens the electric coalescence in the strong electric field area and the crude oil moves from bottom to top Its main feature is that it can use strong electric field to directly feed and crude oil to flow horizontally during operation. In the electric desalination dehydrator of the present invention, a strong electric field coalescence zone (5) is provided along the axial direction of the tank body from the oil-water mixture inlet end of the tank body (1), and an oil outlet pipe (5) is provided on the top of the tank body purified crude oil outlet end ( 10), the strong electric field coalescence area is provided with at least two layers of planar electrode plates (6) perpendicular to the axis of the tank body, and the electrode plates of each layer are parallel to each other. A feed distributor (4) is arranged in the tank, and a spout is arranged on it, and the oil-water mixture is sprayed into the strong electric field between all adjacent two-layer electrode plates. A settling separation zone (7) can also be set between the strong electric field coalescence zone and the outlet end of the purified crude oil in the tank.

The invention relates to a composite biological agent and a preparation method thereof. The composite biological agent is mixed by seaweed physiological activator extracting solution and rhizosphere promotion bacterium liquid according to the volume ratio of (1-20):100. The composite biological agent contains a plurality of physiological activators and rhizosphere promotion flora, and has a plurality of advantages of resisting disease, moving soil, being free of public nuisance and the like.

The invention discloses a device for collecting and classifying leaked oil, which belongs to the technical field of oil pollution cleaning on the water surface. The device includes: a separation processing component, which is arranged on a water surface moving component, and the separation processing component is extracted through an external liquid suction power part and a liquid transfer pipe The oil-liquid mixture on the water surface, the separation treatment component includes a treatment box, one side of the treatment box is provided with a mixed liquid inlet pipe connected to the liquid transfer pipe, and at least two inlet guide sleeves are arranged in the mixed liquid inlet pipe, and the two inlet guide sleeves The ports are round and of different sizes. The small end of the aperture is set at the end of the outlet direction of the oil-water mixture, and the large end of the aperture is set at the end of the flow direction of the oil-water mixture. The treatment box is equipped with a first oil-water separation chamber and a second oil-water separation chamber. chamber and drainage chamber. The invention promotes the rupture of the oil particle film through centrifugal separation and sedimentation separation to improve the oil particle coalescence effect to increase the recovery of leaked crude oil, and ensures the recovery of oil slicks with a particle size of less than 100 μm, reducing the pollution of the leaked crude oil to the environment and leakage loss.
