Description
Technical field
The invention belongs to contaminated soil process fields, and in particular to a kind of application low concentration oil-polluted soils prepare slope protection
Brick method.
Background technique
Low concentration oil-polluted soils fecund is raw in industries such as oil refining, coal gas, coal tar processing, pitch processing.With me
The transition of state's development, such plant area gradually moves, is transformed, but the low concentration oil-polluted soils earth volume carried over is huge
Greatly, the restorative procedure of low concentration oil-polluted soils (total petroleum hydrocarbon concentration is no more than 5mg/kg) is more mature, but repairs
Soil outlet afterwards is always the problem that government, enterprise face.The processing mode of soil after China is repaired at present mainly has green
Change, backfill, paving the way, making 4 kinds of cement.Wherein afforest more demanding to soil soil property and the content of organic matter, and dosage is less；
Whether backfill is higher to the mechanical property requirements of soil, furthermore backfill and also need to be determined according to the requirement of owner；It paves the way by soil
The limitation of earth transportation range, cost improves rapidly when long-distance transport；Production cement products then have strictly the chemical component of soil
It is required that additionally demand of the heavy dependence locality to cement products.In summary 4 kinds of methods, it can be seen that the pollution after reparation
Soil outlet is limited, and now the contaminated soil after many site remediations in China take concentration bank up also demonstrate its be difficult to again it is sharp
Difficulty.
In order to solve the problems, such as to dispose after soil after repairing, low concentration oil-polluted soils are prepared as gently by present invention proposition
The method of matter revetment brick, so that low concentration oil-polluted soils can be with disposal of resources.Publication No. CN10235870A's is special
Benefit discloses a kind of method with high chromium-polluted soil sintering preparing ceramsite, and briquetting pressure is high, calcining time is long, roasting temperature
Degree is high, causes the cost of manufacture of haydite very high, and the haydite density produced is high, deficiency in economic performance；Publication No.
The patent of CN102173850A discloses the energy-saving contaminated soil of one kind and desilting sediment disposes potting grain technology jointly,
Demand to river bottom mud seriously limits the application region of the technology, and its calcining time is long, leads to ceramic product cost
It improves.In conclusion now China's contaminated soil preparation resource utilization haydite or revetment brick technology there are it is at high cost, by
The problem of to territory restriction.
Summary of the invention
The purpose of the present invention is to provide a kind of application low concentration oil-polluted soils to prepare revetment brick method.
The present invention to achieve the above object, using following technical scheme:
A kind of disposal of resources method of low concentration oil-polluted soils, comprising the following steps:
(1) petroleum soil is crushed to 80 mesh by physics mode hereinafter, and carrying out partial size screening by vibrating screen；
(2) different according to soil chemistry component, the Extra-fine sand of 0-40%, the coarse sand of 0-10%, suitable quantity of water are added, and will be former
Material is uniformly mixed.
(3) mixed raw material is sent into brickmaking machine and carries out brickmaking, obtain raw adobe.
(4) it by the life brick blank drying in step (3) and is sent into rotary kiln and roasts certain time at high temperature.
(5) after being burnt into revetment brick natural cooling, the revetment brick prepared with low concentration oil-polluted soils is obtained.
(6) tail gas that step (4) generates discharges after reaching standard by cooling, dust removal process, detection indices.
In the present invention, it is preferred to, physics crumbling method described in step (1) is refered in particular to using ball milling to low concentration petroleum
Contaminated soil is ground.
In the present invention, it is preferred to, Extra-fine sand in step (2), coarse sand additive amount test obtain in accordance with the following methods: will
Low concentration oil-polluted soils are separately added into the Extra-fine sand of 0-40% and the coarse sand of 0-10%, form after mixing, are placed in a furnace
Roasting, maturing temperature are selected as 850-1250 DEG C, and calcining time is 10-25 minutes.Natural cooling after roasting obtains lightweight slope protection
Brick product.Oil content, revetment brick product quality in revetment brick are detected, when the former is up to standard, the latter is product demand value, at this time
Proportion scale, temperature, the time be actual demand value.Preferably, low concentration oil-polluted soils, Extra-fine sand, coarse sand and water
Ratio are as follows: 100:10:3:5-100:20:5:0；Maturing temperature is 1000-1250 DEG C；Calcining time is 15min；
In the present invention, it is preferred to, Extra-fine sand described in step (2) is that desiccation Extra-fine sand is often used in architectural engineering.
In the present invention, it is preferred to, rotary kiln described in step (4) is revetment brick rotary kiln special.
In the present invention, it is preferred to, revetment brick described in step (5) refers in particular to lightweight revetment brick.
Compared with prior art, the beneficial effects of the present invention are:
Application low concentration oil-polluted soils through the invention prepare revetment brick method, can be by low concentration oil pollution
Soil is recycled, and obtains revetment brick, solve the preparation resource utilization of China's contaminated soil now haydite or
The technology of revetment brick there are problems that it is at high cost, by territory restriction.
