The preparation of functionalized reduced graphene oxide (RGO) composite materials on various fibrous substrates has been proposed. The functionalized RGO composite fibrous materials absorb various types of oils efficiently within 20 seconds, with great absorption capacity. The maximum absorption capacity values for bicycle chain oil and used motorcycle engine oil are 880.8% and 839.1%, respectively. Simply squeezing the functionalized RGO composite materials allows the removal of the absorbed oil for reuse. The functionalized RGO composite fibrous materials have been used to efficiently separate oil/water mixture through a flowing system. Having the advantages of faster absorption rate, reusability, and low-costs, the functionalized RGO composite fibrous materials holds great potential as a superabsorbent for efficient removal and recovery of oil spills, and for separation of water/oil mixtures.

The invention provides a marine oil spill recovery device based on an air grid, and belongs to the field of marine oil spill recovery devices; the marine oil spill recovery device based on the air grid is placed on the sea surface, an air pump, a water pump and an oil pump are placed on a ship, a water suction pump and the air pump are turned on, pressure in an oil cleaning device box body is lowered, the water enters the oil cleaning device box body through an oil water round tube, and high pressure gas passes out from a nozzle through a high pressure pipe, and emulsifier from an emulsifier box is atomized into a circular tube grid. Since the upper end of a round tube is provided with air holes, the gas overflows from the air holes and floats upward with a small density of oil. At the same time, the emulsifier makes the oil become free, and makes bubbles float up to the surface easier. A funnel-type oil cover contacts the oil surface to form a closed space, and then the oil pump pumpsthe floating oil for recycling. The marine oil spill recovery device based on the air grid utilizes the bubble to make the physical method of oil and water layer to separate and recover the oil and water, has the characteristics of green environmental protection, convenient and easy operation, high recovery efficiency, and application prospect is broad.

The invention relates to a foaming type degradable water surface oil spill dispersant and a preparation method thereof, and belongs to the field of water body pollution prevention and control. According to the dispersing agent, a nonionic surfactant, an anionic surfactant, an adhesive, an acid agent, an alkaline agent and a filler are compounded according to a specific proportion, so that a largenumber of bubbles are generated after the dispersing agent is added into a water body, a rapid stirring effect is achieved, spilled oil can be rapidly dispersed and emulsified, and emulsified oil drops are small in particle size and good in dispersion effect. The active agent is a bio-based environment-friendly surfactant, so that the oil spill dispersant is environmentally friendly, is easy to degrade, causes little secondary pollution to a water area, and is suitable for various water surface environments such as oceans, lakes and the like.

The invention relates to a baking dish. The baking dish includes a dish-shaped body (21), an oil spilling hole (22) is formed in the dish-shaped body (21), the baking dish is characterized in that a plurality of bulging parts (23) are arranged on the upper end surface of the dish-shaped body (21) at intervals, and a whole supporting surface used for placing foods are formed wholly by the upper endsurfaces of the bulging parts (23). The invention further discloses an air fryer including the baking dish. Compared with the prior art, the baking dish can prevent the foods from plugging the oil spilling hole, thus the foods are separated from grease, and the air fryer including the baking dish can promote hot air to heat the foods to improve the cooking effect.

The invention relates to an oil spilling repair agent, a preparation method thereof, and an oil spilling in-situ repair method. The preparation method of the oil spilling repair agent comprises the steps: a first carrier is provided and is a wood fiber carrier of a porous structure; a microbial agent suspension is provided, the first carrier is mixed with the microbial agent suspension to enable microorganisms to be adsorbed by the first carrier, and a second carrier is obtained; and an aqueous solution containing agar and a surfactant is provided, the second carrier and the aqueous solution are mixed in a container, thus the second carrier is wrapped with the agar to form an intermediate, the intermediate in the container is dispersed to form particles, the particles are blown away through airflow, and the oil spilling repair agent is obtained. The density of the oil spilling repair agent obtained through the preparation method is smaller than the density of water, thus the oil spilling repair agent can be dispersed and float on the water surface, with step-by-step crushing and degradation of the agar in the water environment, the microorganisms adsorbed by the wood fiber carrierare released step by step and make full contact with oil contamination on the water surface, and the good in-situ repair effect is achieved.
