Description
Technical field
The present invention relates to field of environmental technology, relate in particular to the innocuity disposal system of a kind of high salt mud.
Background technology
Oil gas field trade effluent mainly includes well-drilling waste water, acid fracturing waste water, workover treatment waste water, recover the oil (gas) waste water
Deng, there is the features such as high temperature, high salt, high ammonia nitrogen, high COD, biodegradability is poor, generally individually needs to use flocculating sedimentation and chemical oxygen
Change processes technique, can produce substantial amounts of high salt, high organic pollution mud, generally individually carry out according to hazardous waste in processing procedure
Management and disposal, current each Sewage Disposal Treatment of Sludge mainly has two kinds of approach, and one is to fill out science and engineering at reason according to hazardous waste
Skill carries out landfill stabilization, and site selection of landfill difficulty, builds and operational and administrative expenses is the highest, and there is long-term hidden danger；Two be with
Drilling well solid refuse etc. carries out cured together, but due to mud complicated, containing the chemical agent residues such as oxidant, stone
The pollutant load such as oils, chloride ion is the highest, after cured, has many percolates the most unavoidably and oozes out, under peripherally
Water and soil earth cause bigger hidden danger, existing sludge disposal technology be very difficult to except or fixing mud in the inorganic salts such as chloride ion,
And chemical agent residue, easily cause subsoil water and soil pollution, such as Publication No. CN101172738, the time of disclosure is
On May 7th, 2008, the Chinese invention patent document of entitled " method of oily sludge harmless treatment ", disclose a kind of dirty
The method of mud harmless treatment, the method comprising the steps of 1. by oily sludge centralized collection to together；2. will collect together
Liquid oily sludge carries out homogenizing, mixes homogenizing process through one section, makes various oily sludge be sufficiently mixed, and forms physics and change
Learn the character liquid oily sludge relative to stable equilibrium；3. the liquid oily sludge after mixing homogenizing is transported to microorganism aerobic and sends out
Ferment processing means, carries out the aerobic microbiological oxidation fermentation process for the first time of oily sludge；4. oily sludge is converted into biological dirty
Mud carries out dehydration and concentrates；5. second time fermentation process is carried out；6. the mud after fermentation is converted into organic fertilizer to be used for soil and change
Good, afforestation or Crops in Applying Fertilizer.Provide the benefit that owing to the method processing cost of the present invention is cheap, simple to operate, investment
Few, floor space is little, makes the cost of sludge dewatering obtain the biggest reduction.Utilize this processing method, oily sludge can be made
Transform into the organic fertilizer of high-quality for agricultural production, thus realize cleaning and produce, the purpose of protection environment, have well
Promotion prospect, but this method, owing in oily sludge, content of chemical substances is higher, use microbial process to carry out processing its effect
Fruit is more general and relatively costly, and the mud after process still contains a lot of harmful substance.
For another example Publication No. CN102039301A, the time of disclosure is on May 4th, 2011, entitled " a kind of oily sludge money
Source, Harmless and Comprehensive Disposal technique " Chinese invention patent document, disclose the processing method of a kind of oily sludge, its mistake
Journey is divided into four steps: first step oily sludge pretreatment, and oily sludge becomes liquefaction sewage sludge after adding water, heat and stirring, and
It is sorted by stainless steel mesh；Second step oily sludge quenched, adds breakdown of emulsion in the liquefaction sewage sludge through sorting
Oily sludge is carried out quenched by agent and flocculant；The three phase centrifugation of the 3rd step oily sludge separates, and isolated oil enters profit
Piece-rate system reclaims crude oil, and isolated water is delivered in oily sludge pre-treatment step recycle, and isolated residue contains
The solid impurity and the scum silica frost that sub-elect in greasy dirt and greasy filth pretreatment enter Rotation error after drying；4th step remains
Remaining oily sludge and biomass multifuel combustion, residue oily sludge and the solid impurity sub-elected and scum silica frost are returning after mixing with biomass
Rotary kiln carries out high temperature incineration process, eliminates the secondary pollution of oily sludge, and high-temperature flue gas is carried out waste heat recovery, this side
In case, the water directly recycling after three phase centrifugation separates can make separating effect weaken, and oily sludge carries out burning and also can produce
Substantial amounts of dust and harmful vapors.
In sum, problems of the prior art are as follows:
One, prior art processes mud, if filling out reason process technique according to hazardous waste to carry out landfill stabilization, site selection of landfill is stranded
Difficulty, builds and operational and administrative expenses is the highest, and there is long-term hidden danger；If carried out at solidification together with drilling well solid refuse etc.
Reason, but due to mud complicated, containing chemical agent residues such as oxidants, the pollutant load such as petroleum-type, chloride ion is the most relatively
Height, after cured, has many percolates the most unavoidably and oozes out, to descending water and soil earth to cause bigger hidden danger peripherally, and, high
The biodegradability of salt mud is poor, and Biochemical Treatment is the best, burns and then produces even more serious secondary pollution.
Two, processing the scheme of high salt mud in prior art, step is responsible for, and processes time long process cost high, and imitates
Rate is general.
