Description

A kind of processing method of oily sludge
Technical field
The present invention relates to a kind of processing method of oily sludge more particularly to a kind of safety and environmental protection processing base oil mud, drosses With the method for residual active sludge caused by biochemical treatment unit, belong to field of environment engineering.
Background technology
Demand with the world to oil and mineral products is continuously increased, surging oil and mineral products price, and each oil is stimulated to provide Source state, which tries to be the first, develops new resources, new technology, will produce during oil exploitation, transport, refining and oily waste water treatment a large amount of Oily solid sludge-oily sludge.Oily sludge includes base oil mud, residual activity caused by dross and biochemical treatment unit Sludge;General oil content is 10% ~ 50% in sludge, and moisture content is 40% ~ 90%.According to statistics, in China's oil chemical industries, grand celebration Oil field generates oily sludge nearly 1.43 × 10 every year5m3, Shengli Oil Field generates oily sludge 1.0 × 10 every year5T or more, and And yield is also rising year by year;More seriously, in petrochemical industry generated greasy filth quantity far more than oil field greasy filth number Amount.In oily sludge containing a large amount of benzene homologues, phenols, fear, the noxious material of the foul smellings such as pyrene, if oily sludge cannot have Effect processing, it will seriously pollute environment.There are biological ground till, biological einforcement method, centrifugation to the method for disposal of oily sludge Method, wet oxidation process, solvent extraction etc..
Domestic and foreign scholars are directed to oily sludge large viscosity in the past 20 years, and emulsification degree is high, and oil, mud, the separation of 3 phase difficulty of water etc. are asked Topic, on biological ground, till, biological flotation method, centrifugal separation, wet oxidation process, solvent extraction etc. have all been done a large amount of Research work, but so far, still not fairly perfect processing method.The processing of oily sludge is always to annoying the country The a great problem in outer oil field and petrochemical industry.
Currently, the processing to oily sludge is still in the centrifugation rank that traditional plain sedimentation concentrates and effect is undesirable Section.
It is in sticky colloid since the moisture content and oil content that centrifuge arranged solid formation are all higher, thus it is inconvenient Transport, it is inconvenient
Directly burn, it is also inconvenient to carry out drying and other treatment(Moisture content is high, causes energy consumption too high).Since demulsifier can will be in greasy filth Water and the single-phase mixture of oily emulsification state become the two-phase liquid of oil and water, it is active high, quick the advantages that, add demulsification Agent is the most common breaking method of current oil extraction.But in greasy filth demulsification, because greasy filth component is complicated, source quantity is more The factors such as change, moisture height, so that there is oil recovery rates is low for common demulsifier directly use, biological degradability difference etc. is scarce Point.And demulsifier disclosed in existing literature is not directed to the demulsifier of greasy filth, and of high cost, is unfavorable for practical application.Demulsification Greasy filth afterwards still needs to carry out following process, could form effective final process.It can be seen that still lacking a kind of effectively to containing The resource reclaim that utility in greasy dirt is carried out, separation or drying process to Residual water in oily sludge, and To the method for the harmlessness disposing that the pollutant in oily sludge is carried out.Therefore it provides a kind of operation operation is simple, resource is returned Harvest that complete, moisture removal is controllable and the method for abatement of pollution economic, reliable and safe processing " oily sludge " more thoroughly, tool There is important meaning.
Invention content
It is an object of the present invention to provide the composite demulsifying agents and system of a kind of effective and perfect integrated treatment oily sludge Processing method, this method can effectively recycle petroleum substance useful in base oil mud and dross, solve oil Grease, the oil possibility that separation problem generates oily sludge in storage and disposal process admittedly, which leak, in mud pollutes ring into air The odorant in border is thoroughly purified, and with advanced treating qualified discharge and original exhaust treatment system can be added, not generated smelly Gas pollutes.
