specific Embodiment approach 1

[0038] An intensive oil sludge treatment method, the treatment method comprises the following steps:

[0039] Step 1. Pretreatment of sludge:

[0040] Take the sewage sludge, import it into the inside of the batching tank, add the water source, stir evenly, and obtain the initial mixing liquid of the sewage sludge;

[0041] Step 2. Intensive treatment of sludge:

[0042] The sludge primary mixture liquid is transported to the inside of the stirring tank, and the sludge primary mixture liquid is simultaneously subjected to mechanical stirring treatment, ultrasonic treatment and heating treatment inside the stirring tank, and the sewage sludge slurry chemical material is obtained after the treatment;

[0043] Step 3. Separation and treatment of sludge:

[0044] Sludge material is taken for separation treatment.

[0045] In said step 1, the sludge includes fluid sludge and solid sludge;

[0046] When the sludge is fluid sludge, the pretreatment step of the sludge is as follow...

[0064] An intensive oil sludge treatment method, the treatment method comprises the following steps:

[0065] Step 1. Pretreatment of sludge:

[0066] Treatment of refinery and drilling sludge:

[0067] Take the liquid sludge, import it into the batching tank, add an appropriate amount of water, and stir evenly to obtain the initial stirring liquid of the sludge;

[0068] Treatment of solid sludge:

[0069] The solid oily sludge is taken, and after being initially screened by the screen, it is transported to the inside of the drum screening sludge washing machine by the elevator for secondary screening;

[0070] The coarse material screened out of the secondary screening enters the crusher for crushing after screening, and then enters the drum screening machine for screening again;

[0071] The fine material screened out by the second time is introduced into the inside of the batching tank, and an appropriate amount of water is added, and after stirring evenly, the initial ...

Abstract

The invention relates to a treatment method of oily sludge, and particularly relates to an intensive treatment method of oily sludge. The treatment method comprises the following steps of a step I, pretreatment of the oily sludge; a step II, multi-gradient coupling treatment of the oily sludge: conveying oily-sludge primarily mixed feed liquid obtained by mixing treatment into the interior of an agitation tank, and subjecting the oily-sludge primarily mixed feed liquid to mechanical agitation treatment, ultrasonic treatment and heating treatment at the same time in the interior of the agitation tank, so as to obtain an oily-sludge pulpified material after the treatment; a third step, separation treatment of the oily sludge. The intensive treatment method can be used for effectively solvinga problem existing in the treatment process of the oily sludge in the prior art; according to the treatment method of the oily sludge, which is provided by the invention, a chemical agent does not need to be added in the treatment process; the treatment efficiency is high; the treatment capacity is high; oil liquid, silt and water liquid in the oily sludge can be effectively separated; the disposal cost of the oily sludge can be decreased and the pollution problem of oil-containing sludge can be quickly and thoroughly solved.

Description

technical field [0001] The invention relates to a treatment method of sewage sludge, in particular to an intensive treatment method of oil sludge. Background technique [0002] Sludge is the main pollutant produced in the process of petroleum development, production and processing. According to different causes, it is mainly divided into landing sludge, tank bottom sludge, ground oil spill, oil refinery sludge, etc. [0003] The composition of oil sludge is extremely complex, and varies with geological conditions and production processes. It is generally composed of water, soil, and oily organic matter. Sludge sludge mainly has the following characteristics: high water content and large volume; complex composition and difficult treatment; it contains a large amount of dirty oil and combustible substances; most of the harmful components exceed the emission standards. At present, although there are many oily sludge pollution control technologies at home and abroad, there is ...
