Abstract

The invention discloses a biodegradable floating bed with a function of adsorbing sea water polluted by oil spillage and belongs to the technical field of sea oil spillage pollution physical adsorption treatment. 6 to 8 poly-beta hydroxyl butyrate composite porous boards with the function of adsorbing petroleum hydrocarbon are arranged in parallel sequentially and vertically to form the vertical plates of the floating bed; horizontal plates are positioned below the vertical plates; 5 poly-beta hydroxyl butyrate composite porous boards with the function of adsorbing the petroleum hydrocarbon are arranged in parallel sequentially and horizontally to form the horizontal plates of the floating bed; the connecting parts of the horizontal porous plates and the vertical porous plates are bound by cellosilk ropes; the cellosilk ropes are used for connecting a screen mesh bag made from poly-beta hydroxyl butyrate; and grain adsorbent with the function of adsorbing the petroleum hydrocarbon is filled in the screen mesh bag. The biodegradable floating bed can be conveniently applied to physical adsorption treatment for the sea water polluted by oil spillage and has the characteristics of high treatment efficiency, low cost, no secondary pollution, simpleness in operation and the like.

Description

technical field [0001] The invention belongs to the technical field of physical adsorption treatment of oil-spill-polluted seawater, and in particular relates to a biodegradable floating bed capable of absorbing oil-spill-polluted seawater. Background technique [0002] In recent years, with the increasing demand for oil and its products in various countries around the world, oil spill accidents have occurred frequently in the process of offshore mining, loading and unloading, transportation and utilization of oil, which not only caused a large amount of crude oil loss, but also caused serious pollution to the environment. It is increasingly threatening the ecological environment of the ocean and land, and has long-term harm to the marine environment, natural resources and aquaculture resources. Therefore, marine oil spill pollution has become a major environmental problem that people must face. [0003] At present, there are mainly physical methods, chemical methods and bio...
