Effects Of Chemical Dispersants On The Formation Of Oil-suspended Particulate Matter Aggregates

With the rapid development of offshore oil transport industry,the oil pollution caused by marine oil spill happens more frequently.People are paying increasing attention to the environmental issues,and the research of the beach oil spill treatment and disposal is gradually putting on the agenda.People found that one kind of oil-mineral particulate matter aggregates formed in the natural environment during the process of dealing with the beach oil pollution can promote the diffusion of the oil to the ocean,besides,it could make great contribute to the biological degradation of the oil.It is discussed in this paper that the impact of the typical sedimentary particulate matter in Lai Zhou Bay to the oil-condensation kinetics,which means that it is researched in this paper that the influence of the characteristics of the typical sedimentary particles which is produced in the process of the formation of the oil-mineral-aggregate.It is the reciprocating oscillator that is used to simulate the tidal movement in the marine environment,Sheng Li oil、Sheng Cai Er Kuang oil and Tuo Si oil are chosen to be the polluting oil samples,while the sedimentary particles include the beach sediments.And the sea water processed by filtration is used as the reaction medium.It is explored and analyzed is 2:10 which contains the impact of the size of suspended particle,the impact of oil property,and the impact of species of the size of suspended particle,the impact of oil property,and the impact of species of suspended particulate as well as the influence of salinity and so on.The conclusions are listed as the following.The impact of the size of the suspended particles on the formation amount begins to be prominent in 0.038 mm.and start from this size,the smaller the particle size is,the bigger the growth rate of the aggregates formed in the beginning time of the process is,and the greater the total formation is;the part of the sample which plays a major role in the process of aggregates formation is the suspended particulate matter.Reciprocating oscillator was used in the experiment to simulate the tidal movement.Choose the suction filter water as reaction medium.The smaller the particle size of oil removal effect is better;the same same size sediment is different.The amount of the mixing energy determines the rate and the intensity of the reaction.Increase in the number of particles,OSA agglomeration of incremental into increasing trend.
