Embodiment 1

[0018] Put 6 poly-β-hydroxybutyrate-polyoxyethylene composite porous plates with a height of 20cm, a width of 4cm, and a length of 5m that have a biodegradable function for petroleum hydrocarbons. 40cm, forming the vertical surface of the floating bed; 8 poly-β-hydroxybutyrate-polyoxyethylene composite porous plates with a height of 10cm, a width of 60cm, and a length of 2.5m, which have biodegradation functions for petroleum hydrocarbons, are placed side by side in sequence. The distance between every two porous plates is 4cm to form the horizontal surface of the floating bed; the position of the horizontal surface is above the vertical surface; fiber filaments are used at the junction of the horizontal and vertical porous Rope tied. The biodegradable floating bed was applied to the treatment of seawater polluted by oil spills, and the seawater before and after treatment was sampled and analyzed. The results showed that the concentration of petroleum hydrocarbons in seawater ...

Embodiment 2

[0020] Put 7 poly-β-hydroxybutyrate-polyoxyethylene composite porous plates with a height of 25cm, a width of 5cm, and a length of 5.5m that have a biodegradable function on petroleum hydrocarbons. A distance of 40cm constitutes the vertical surface of the floating bed; 8 poly-β-hydroxybutyrate-polyoxyethylene composite porous plates with a height of 13cm, a width of 63cm, and a length of 2.8m that have biodegradation functions for petroleum hydrocarbons are juxtaposed and horizontal The distance between every two perforated plates is 5cm to form the horizontal surface of the floating bed; the position of the horizontal plate is above the vertical plate; fiber Silk rope tied. The biodegradable floating bed was applied to the treatment of seawater polluted by oil spills, and the seawater before and after treatment was sampled and analyzed. The results showed that the concentration of petroleum hydrocarbons in seawater decreased from 2.88mg / L before treatment to 0.01mg / L after t...

Embodiment 3

[0022] Put 8 poly-β-hydroxybutyrate-polyoxyethylene composite porous plates with a height of 25cm, a width of 6cm, and a length of 6m that have a biodegradable function for petroleum hydrocarbons. 40cm, forming the vertical surface of the floating bed; 8 poly-β-hydroxybutyrate-polyoxyethylene composite porous plates with a height of 15cm, a width of 65cm, and a length of 3.0m, which have biodegradation functions for petroleum hydrocarbons, are placed side by side in sequence. The distance between every two porous plates is 6cm to form the horizontal surface of the floating bed; the position of the horizontal surface is above the vertical surface; fiber filaments are used at the junction of the horizontal and vertical porous Rope tied. The biodegradable floating bed was applied to the treatment of seawater polluted by oil spills, and the seawater before and after treatment was sampled and analyzed.

Abstract

The invention discloses a biodegradable floating bed with biodegradation function on spilled oil polluted seawater, belonging to the technical field of biological treatment of spilled oil pollution on sea. 6-8 poly-beta-hydroxybutyrate-polyoxyethylene composite porous plates capable of biodegrading petroleum hydrocarbons are sequentially and vertically arranged in parallel; 8 poly-beta-hydroxybutyrate-polyoxyethylene composite porous plates capable of biodegrading petroleum hydrocarbons are sequentially and horizontally arranged in parallel; the horizontal plate surface is positioned above the vertical plate surface; and the joints of the horizontal porous plates and the vertical porous plates are bound by a fiber rope. The invention can be conveniently used for biodegradation treatment of spilled oil polluted seawater, has the characteristics of high treatment efficiency, low cost, no secondary pollution and the like, and is simple to operate.

Description

technical field [0001] The invention belongs to the technical field of biological treatment of seawater polluted by oil spills, and in particular relates to a biodegradable floating bed capable of biodegrading seawater polluted by oil spills. 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 b...
