Description
Technical field
The invention belongs to the biologic treating technique field that is subjected to the oil spill seawater, be specifically related to a kind of biodegradable floating bed that the oil spill seawater is had biological degradation function.
Background technology
In recent years; Along with the demand of countries in the world to oil and goods increase thereof; At sea exploit, load and unload, transport and utilize that oil spill accident happens occasionally in the oil process; Not only cause a large amount of crude oil to run off; Also environment is caused severe contamination, threatening the ecotope of ocean and land-based area with being on the rise, ocean environment, natural resources and culture resources etc. are all had secular harm; Therefore, marine oil spill pollutes has become the great environmental problem that people must face.
The method of disposing the marine oil spill pollution at present both at home and abroad mainly contains physics method, chemical method and biological process.Chemical method is the technological line of comparative maturity in point-source pollution is administered, and is promoted widely and uses.But in the marine oil spill Pollution abatement, adopt chemical method, need in the ocean, add chemical agent, the chemical agent that wherein adds possibly produce secondary pollution on the one hand, can produce short-term or secular influence to the marine eco-environment on the other hand.Characteristics such as bioremediation technology has efficiently, economy, safety, non-secondary pollution; Become the on-the-spot important selection approach that marine oil spill pollutes of removing; The oil sheet that can't remove mechanism particularly; When chemical agent was used in restriction again simultaneously, the utilization biological restoration can be showed its bigger superiority.Physisorphtion is a kind of processing efficiency height, low, the no sediment pollution of cost, simple to operate and can not cause secondary pollution and destructive method to the marine eco-environment, can solve the existing problem of chemical method preferably.But; The cycle of bioremediation technology is long; Be subjected to whether to exist the restriction of highly effective petroleum alkane degradation bacterium simultaneously; Physisorphtion faces the problem that absorption need be remarketed sorbent material after saturated; Then can remedy the deficiency of the two if physisorphtion and biological degradation can be combined, be used to dispose the marine oil spill pollution and will have bigger advantage.
But; Pollute at marine oil spill for technology that physisorphtion and biological degradation are combined and further to be promoted and to use in handling; Develop the physical adsorption associating biological degradation measure of various ways; For improve operational efficiency, the cost and reduce working cost and have great importance of reducing investment outlay, but also lack the technology and research report of this aspect at present.
Summary of the invention
The purpose of this invention is to provide a kind of biodegradable floating bed that the oil spill seawater is had biological degradation function.Particular content of the present invention is following:
The technical scheme that the present invention adopted is: with 6 to 8 height is that 20～25cm, width are that 4～6cm, length are 5～6m has biological degradation function to petroleum hydrocarbon the compound porous plate of poly beta-hydroxybutyrate-polyoxyethylene vertical display arranged side by side successively; At a distance of 40cm, form the vertical plate face of floating bed between per two porous plates; With 8 height is that 10～15cm, width are that 60～65cm, length are that 2.5～3.0m puts the compound porous plate of the poly beta-hydroxybutyrate-polyoxyethylene level arranged side by side successively that petroleum hydrocarbon has biological degradation function; At a distance of 4～6cm, form the leveling board face of floating bed between per two porous plates; The position of leveling board face is above the vertical plate face; The binding of fiber yarn rope is used in the porous plate junction of porous plate that level is put and vertical display.
It is said that petroleum hydrocarbon is had the compound porous plate making processes of poly beta-hydroxybutyrate-polyoxyethylene of biological degradation function is following:
(1) distilled water is spurted in the container that liquid nitrogen is housed quick freezing and made subsphaeroidal ice hockey particle, after the screen cloth screening, the ice hockey particle of choosing size range respectively and be 50～100 μ m is for use;
(2) garbled ice hockey particle is placed in the mould cavity and compacting;
(3) the preparation massfraction is 10% poly beta-hydroxybutyrate chloroformic solution; The preparation massfraction is 10% polyoxyethylene chloroformic solution; In the volume ratio of poly beta-hydroxybutyrate chloroformic solution and polyoxyethylene chloroformic solution be 5: 1 ratio with the two thorough mixing, and this mixed solution is cooled to-15 ℃;
(4) mixed solution in the step (3) is poured in the mould in the step (2), and together put into liquid nitrogen freeze settled 6 hours, obtain solid mixt after the taking-up demoulding; To obtain the compound porous plate of poly beta-hydroxybutyrate-polyoxyethylene behind this solid mixt vacuum lyophilization removal chloroform and the ice hockey particle;
(5) the compound porous plate of poly beta-hydroxybutyrate-polyoxyethylene in the step (4) is cultivated 24h in the petroleum hydrocarbon degradation bacteria culture fluid; Petroleum hydrocarbon degradation bacterium is absorbed and fixed on the compound porous plate of poly beta-hydroxybutyrate-polyoxyethylene, and wherein the bacteria containing amount of petroleum hydrocarbon degradation bacteria culture fluid is 5 * 10
