High-efficiency treatment process for removing marine spill oil
The invention provides a high-efficiency treatment process for removing marine spill oil. The process comprises the steps that 1, sediment taken from a muddy beach at the mouth of the Yellow River is air-dried and screened to obtain particles with the particle sizes not more than 38 microns, and an appropriate number of particles and seawater are mixed to prepare a particle solution of 1.0-3.0 g/L, and the particle solution is canned and stored; 2, a waste cleaning boat is used for spraying oil dispersant and the particle solution with the appropriate concentration to the surface layer of the spill oil, and a stirring device is used for enabling a spill oil region to maintain a turbulent fluctuation state until the spill oil is cleared away; the mass ratio of the particles to the oil dispersant ranges from 7.5:1 to 12.0:1, and the use amount of the oil dispersant accounts for 15-20 percent of the amount of the spill oil. According to the process, the particles and the oil dispersant are combined to remove the marine spill oil, the oil dispersant is used for promoting dispersion of the spill oil, power is supplied through the hydrodynamic condition of the ocean, a propeller of the waste cleaning boat and the shipborne stirring device, particle materials play a role of dispersing agents and oil gelling agents, and the clearance efficiency of the spill oil is greatly improved on the basis of reducing the use amount of the oil dispersant.
