Description
Technical field
It is that a kind of oil field mining liquid central treating station contains the present invention relates to oil field mining liquid contained Mud Treatment Technology field
Greasy dirt processing method and processing device.
Background technique
Oil field mining liquid central treating station oily sludge refers to is deposited on various storages during oil field mining liquid collection is defeated
Tank(Crude Treatment system, sewage disposal system)A kind of oily solid sludge of bottom.Currently, in entering with most oilfields
Later period mining phase, the oily sludge that oil field mining liquid central treating station generates are growing day by day.Oily sludge ingredient is extremely complex,
It is mainly made of oil emulsion, water, solid suspension and various chemical agents etc., the salt content of oily sludge is very high(Sewage mine
Change degree is 8 × 104Mg/L to 14 × 104mg/L), oil content accounts for the 10% to 20% of dewatered sludge, and viscosity is big, and mud granule is superfine, is
The hydroaropic substance of colloid form structure, the settleability and filterability of sludge are poor, and dehydration difficulty is very big.In addition, also containing in greasy dirt
There is the noxious material of the stenches such as a certain amount of benzene homologues, phenols, anthracene, pyrene.
With industrial rapid development, environmental pollution is got worse.And people to the protection of living environment and change
Good will, which is known, constantly to be reinforced, and the relevant laws and regulations of environmental protection also have stringent regulation to the discharge standard of oily sludge.Root
The new pollution emission standard formulated according to national four ministries and commissions joint:Untreated oily sludge discharge charging standard is 1000 yuan/ton, this
The production cost of enterprise will be greatly increased.Oily sludge has been put into《National Hazard waste catalogue》In oily waste water species,《State
Family's promotion law on cleaner production》It is required that innoxious and recycling treatment must be carried out to oily sludge.
The processing standard of oily sludge, is generally determined by the whereabouts after Treatment of Sludge, at domestic and international most important terminal
The mode of setting is landfill and builds the road that, to avoid generating adverse effect to soil, various countries provide the index of oil content, in state
On border, due to the difference in geology and geographical conditions, soil is different to the tolerance degree of oils organic matter for various regions, therefore for
TPH in sludge(Total petroleum hydrocarbon)Or oil content, ununified standard in the world, but many countries and regions all bases
The actual conditions of this area propose the corresponding dedicated index in scene in the form of regulation or instructional criterion.The U.S., France add and take
Great Deng state regulation oily sludge oil content, for filling, is used to build the road less than 5% less than 2%.Oily sludge is classified as danger by China
Dangerous solid waste, but quantizating index is not proposed to the oil content in oily sludge, only in GB4284-84《It is dirty in agricultural sludge
Contaminate the standard of object control》And GB/T23486-2009《Urban sewage treatment plant sludge disposes afforestation shale》In, to agriculture
It is provided with sludge and afforestation with the mineral oil content in mud, it is desirable that highest permissible level≤3000mg/kg(0.3%).
On 2 16th, 2011 publication HJ607-2011 of Environmental Protection Department《Waste mineral oil recycles pollution control technology specification》, 2011
On July 1, in implements, it is specified that 5% oily sludge of oil content >, oil-sand should carry out regeneration, and oil content is answered small after greasy filth sand separation
In 2%.
Domestic each main oilfield strengthens contained Mud Treatment Technology research, and the research departments such as each universities and colleges also assist in
Wherein, a variety of process for treating oil-containing sludge and technique have been developed at present, such as:Incineration method, extraction, bioanalysis etc., but because of place
Reason cost requires the factors such as process conditions to limit, and the practical application in industry of institute's research achievement is few, and domestic majority oil field still uses
Landfill method handles oily sludge, and it is serious to fill phenomenon not up to standard;A small number of oil fields are separated by solid-liquid separation using hypergravity, ultrasonic wave penetrates processing
The methods of recycling crude oil, but oily sludge oil content meet the requirement of environmental protection not yet after handling.Therefore, establishing one kind being capable of General Office
