Description
Technical field
The present invention relates to Sludge in Oilfields recovery technique field, specially a kind of biological expedient of tillage oily sludge soil is repaired
Multiple construction technology.
Background technique
The compound for a kind of complexity that oily sludge is made of water oil, water oil emulsion and suspended solid, comprising various
Alkane, aromatic hydrocarbon etc..China generates nearly million tons of oily sludge every year.How harmless treatment is carried out to it, had become
One technical problem urgently to be resolved.
The technology for repairing oily sludge soil at present mainly has peripheral doses, chemical remediation and biological prosthetic, peripheral doses
It is high with the rehabilitation cost of chemical remediation and easily cause secondary pollution, such as a kind of petroleum hydrocarbon contaminated soil renovation technique (patent No.:
CN108246791A) propose that using 60-80 DEG C of air to shorten repairing efficiency to contaminated soil progress stripping with this is then easy to make
Hydrocarbon, which is evaporate into atmosphere, in soil generates secondary pollution.It is biological prosthetic because of its high treating effect and without secondary pollution
The characteristics of, it has broad application prospects；Aiming at the problem that biological prosthetic consuming long period, therefore there is an urgent need to research and develop one
Kind can shorten the restorative procedure that repairing efficiency reduces the oily sludge soil of cost again.
Summary of the invention
In order to achieve the above objectives, the present invention proposes a kind of biological expedient of tillage oily sludge soil remediation construction technology.Including
Following steps:
(A) oily sludge soil is excavated and is stacked；
(B) by the oily sludge soil cutting stacked in step (A), smash, loose puddle；
(C) soil particle after rotary tillage in step (B) is sieved；
(D) by the soil addition Sludge in Oilfields degradation element in step (C) after screening (patent No.:
ZL201010603102.4 it) is puddled；
(E) by the soil planting plants after being puddled in step (D).
Further, it tells to excavate oily sludge soil according to the sequence of from low to high in step (A) and stack, stack and be
Long * wide * high is respectively the heap body of 10*2*1m, and site requirements meets national standard HJ 2035-2013, needs in digging process
Boundary soil is constantly detected, until in soil without obvious hydrocarbon.
Further, mixing is smashed for the first time to soil using Cultivator first in the step (B), utilizing rotary tillage
The blade cut of machine rotation, the oily sludge for smashing bulky grain, it is loose to puddle soil, increase soil porosity, accelerates in soil
The evaporation of moisture.
Further, in the step (C) screening of soil particle to be using sieving machine by partial size be more than 5mm soil
Particle screening, which comes out, to be further crushed, and it is respectively 66* that soil particle of the partial size less than or equal to 5mm, which then tiles as long * wide * high,
The unit of 10*0.35m is further processed.
Further, the microbial flora in Sludge in Oilfields degradation element puddled in the step (D) be by with
What indigenous bacterium compounded.
Further, it needs to add cow dung when puddling Sludge in Oilfields degradation element in the step (D), uses rotation secondary
The machine of ploughing is loose by soil and Sludge in Oilfields degradation element, puddles, smooth.
Further, cow dung is added in the step (D) primarily to carbon N:P ratio in balanced soil, increases soil
The porosity and specific retention of earth are that good environment is created in the growth of microorganism and plant.
Further, in the step (D) spray water primarily to guaranteeing that the humidity of soil meets the growth of microorganism
Required moisture, specific moisture content of the water of sprinkling according to soil.
Further, the plant planted in the step (E) is mainly clover.
The invention has the benefit that
This construction technology process is simple, homogenizes the oily sludge in soil by rotary tillage and screening, tinyization, increases
The specific surface area that Sludge in Oilfields degradation element is reacted with oily sludge, effective to reduce the reaction time, treatment effect is good.
