Technical field
The present invention relates to resource and environment technical field, process with resource innoxious particularly to a kind of oily sludge
Method.
Background technology
Oily sludge is mainly derived from oil exploration, oil development, petroleum refining and crude storage and transportation
In, comprise the big tank of crude oil deposit bed mud, sewage disposal produce oily sludge and because sudden pollusion atmospheric event etc. is former
Land oily sludge etc. because cause.Newly produce oily sludge 4 × 10 through preliminary survey China every year6T about, oily sludge is
Clearly listed in as hazardous waste《National Hazard waste register》, according to《Administrative Regulations on Pollution Discharge Fee Levy》And " row
Dirty fee collecting standard management method ", does not meet the provisions of the relevant regulations issued by the State, hazardous waste collection of drainage dues mark to disposing hazardous waste
It is accurate that for 1000 yuan per ton every time, if processing, disposal is not up to standard, enterprise will pay heavy blowdown cost,《National clean manufacturing promotees
Enter method》With《Solid waste environmental pollution prevention and control method》Also require that and must carry out harmless treatment to oily sludge.
Oily sludge technical research personnel have carried out substantial amounts of research, mainly in terms of disposal of oily sludge both at home and abroad at present
Including:Quenched-mechanical centrifugal method, concentration method, burning method, thermal desorption method, solvent extraction, biological treatment etc., quenched-machinery
Centrifuging advantage is that technique is easily realized, and petroleum substance can reclaim, non-secondary pollution, but the selection of quenched medicament is difficult, builds
If addressing requires higher;Concentration method:Removable free water, to reduce pollution volume, but processes not thorough, there is secondary pollution hidden
Suffer from;Burning method can at utmost minimizing adaptable to raw material, but high energy consumption, equipment investment is big, and process specifications are high,
General heat utilization ratio is not high, it is understood that there may be dust, SO3Deng secondary pollution;The completely inorganization hydro carbons of thermal desorption method medium can return
Receive and utilize, but reaction condition requirement is higher, operation is more complicated;Solvent extraction efficiency high, processes thoroughly, most of petroleum-type
Material extracts and reclaims, but extractant is expensive, during to there is partial loss processing cost high;Biological treatment energy consumption is low,
Processing cost is low, but long processing period, to cycloalkane, aromatic hydrocarbons, heterocyclic treatment effect is poor, and high oil content pollution mud is difficult to be adapted to
Scale, resource cannot reuse;Above technology can carry out the disposal of oily sludge to a certain extent, but can not from innoxious,
Thoroughly oily sludge is solved the problems, such as in resource, minimizing.
Content of the invention
It is an object of the invention to provide a kind of innoxious processing method with resource of oily sludge, solve oil field and produced
The recycling treatment of oily sludge in journey, solves integrated treatment and the Utilizing question of oily sludge simultaneously.
To achieve these goals, present invention employs following technical scheme:Comprise the following steps:
A, oily sludge enter mix homogeneously after reception tank dilutes 2 times by recirculated water and enter through elevator pump to fluid state
Enter thermal washing tank, oily sludge is mixed with recirculated water, heating water, filter press filtrate in hot-water cylinder, and oily sludge is heated to 60-
80 DEG C, and it is diluted to 5 times of raw sewage further, so that crude oil is separated from mud by throwing in biodegradation dispersant, then
Enter three phase separator;
B, make oil, water, mud three phase separation and from oil drain out reclaim crude oil, sewage, mud enter mud purge tank;By throwing
Plus biodegradation abluent, remain oil content in further eccysis sewage, mud;
In c, mud purge tank, sewage enters container air-floating apparatus, and sewage recycles after treatment, mud purge tank bottom
Portion's mud and container air-floating apparatus base sludge enter mud centralized pool;
In d, mud centralized pool, mud is processed through biobelt pressure filter, processes and reaches afterwards after testing by adding Biostimulation agent
Mark discharge.
Wherein, the processing equipment described in step a-d includes:Reception tank, thermal washing tank, three phase separator, dissolved air flotation device,
Mud centralized pool, biobelt pressure filter, clean water tank, settling tank, elevator pump.
Wherein, the spoil disposal of the container air-floating apparatus described in step c-d squeezes into mud centralized pool by sludge pump, and then by biobelt
Pressure filter carries out sludge dewatering, dehydrated sludge, processes rear qualified discharge after testing by adding Biostimulation agent.
Wherein, the pressing filtering liquid producing in the dehydration described in step a-d, squeezes into reception tank, thermal washing tank by elevator pump.
The beneficial effects of the present invention is:After above-mentioned processing method, the Treatment of Sludge that can meet various trait requires
And treatment effect all can reach emission request;By comparing with existing method for sludge treatment, can reach innoxious, resource, subtract
Quantify, non-secondary pollution, energy consumption are low, operating cost is low;After process, oily sludge material oil content < 0.3%, reaches innoxious
Require, can directly fill, meet environmental requirement.
