Description
Technical field
The present invention relates to water pollution prevention and control field, be specifically related to a kind of marine oil overflow dispersion agent and preparation method thereof.
Background technology
The petroleum pollution in ocean overwhelming majority is from mankind's activity, wherein with ship, offshore oil and gas exploitation, and littoral discharge of industrial wastes is main, due to habitat of oil and area of consumption skewness, therefore, world's year petroliferous over half be sea borne by oil carrier, this just brings the threat of petroleum pollution to the ocean accounting for earth surface 71%, the sudden petroleum pollutions such as particularly oil tanker collision, marine oil field leakage.The destruction of petroleum pollution in ocean to Marine ecosystems is difficult to retrieve.Oil is across the sea floating, diffuses to form oil film rapidly.Oil film forms the reoxygenation effect hindering water body, affects marine plankton growth, destroys marine ecology balance, can destroy beachscape in addition, affect beach aesthetic values.
Oil-spill dispersant is by kinds of surface promoting agent and strong infiltrative solvent composition, mainly for the treatment of marine oil overflow and cleaning greasy dirt, is the necessary article administering petroleum pollution in ocean.The mechanism of action of oil-spill dispersant is by oil slick emulsification, forms fine particle and is scattered in water, be mainly applicable to the oil spilling process of exposed waters.Prior art is also few about the document of oil-spill dispersant, such as, describe in CN 102335493A a kind of for there is oil spill accident time carry out oil spilling emulsification by tensio-active agent and carry out the biological oil spilling dispersing agent of quick bio repair simultaneously with microorganism, it is characterized in that the fat corrected milk(FCM) rate of this oil-spill dispersant can reach or exceed the requirement of oil-spill dispersant product GB, and containing degraded oil spilling microorganism in dispersion agent, can with oil co-cultivation remarkable content of all kinds of main organic hydrocarbon component in degraded oil after 24 hours, directly eliminate these poisonous components fast to the pollution of physical environment and harm.Although the tensio-active agent used is rhamnolipid, undesirable in dispersion and emulsion effect.And use yeast preservation fermentation means, use scale limited, poor effect.
But the oil-spill dispersant that prior art exists is unsatisfactory in dispersion and emulsion effect, therefore developing a kind of efficient, eco-friendly oil-spill dispersant is that research in art is crucial.
