Description
Technical field
The present invention relates to a kind of method reclaiming humus from the transudate deriving from urban solid garbage field etc. and
The humus obtained by the method.
Background technology
Humus is complicated organic substance, that it has a change and still do not have the clearest and the most definite structure (supramolecular,
The structure of macromole), it is made up of the branched chain of main but non-exclusive monocycle and the aromatic hydrocarbons of multi-ring (including heterocycle), mainly has
Carboxyl, phenol and hydroxy functional group, also ether, ester, amino etc..
As follows, these materials according to them in different pH value (acid ph value 0-7, pH neutral 7, alkaline ph values
" dissolubility " (more accurately, they form the ability of colloidal state " colloidal sol ") in water 7-14) classifies:
-humic acid (HA) is insoluble at acid ph value and solvable in alkaline ph values
-Fulvinic acid(a necic acid) (FA) is at acid ph value and solvable in alkaline ph values
-humin is at acid ph value and insoluble in alkaline ph values
These dissolubility properties make humus can extract from carbonate minerals such as leonardite, brown coal, mud coal, with
And the extraction from following compound being recently proposed: this compound is by converting and stablizing debirs example in controlled equipment
Organic moiety such as solid municipal waste (S.U.R) produces.
The leonardite formed in the slowly decomposition of organic substance (particularly lignin) is planting in mud coal and brown coal
The phase of the nearest surface oxidation that the geochemistry of thing organic substance converts.It is especially rich in humus, and it is in alkaline aqueous solution
Extract with potassium hydroxide (pH value 9-12).These solution (it can comprise the inorganic salt dissolving in alkaline water with variable) lead to
Often sell according to derived region, there is different humus concentration, especially as the soil improver in agricultural.This side
Face, humus is by soil treatment and is changed soil characteristic by foliage applying (leaf application) and improves
The growth of major part different crops and health.
Specifically, humus improves:
-retention capacity of soil;
-Soil structure and fertilizer degree;Due to the chelating effect of functional group present in humus, it is therefore prevented that nutrient substance and micro-
Secondary element (ferrum, calcium, phosphorus etc.) is washed off, and their utilizability increases in time, thus the growth of beneficially plant
And health.
Humus is the most biological nondegradable;(FA) and big point of high molecular (HA) in they consist of
Son, has hydrophobic part and a hydrophilic functional groups (it is partially acidic), and is the salifie form of they and alkalinous metal, table
Revealing surfactant properties, this makes them can also act as the surfactant in earth and soil cleaning, because passing through
Their chelating ability is also used to be used for them removing hydrocarbon and/or heavy metal in different heavy metals.
Obtained by the controlled oxidation of coal and be similar to humus, but the material of non-natural origin, and carried
Go out as soil improver or for the industrial ash rich in heavy metal is carried out deactivation.
Known according to refuse quality and rubbish amount of cure and rainfall level, the transudate from S.U.R. rubbish can comprise
Humic quality (0.05-5 weight %), it is considered as interesting in industry and commercial object;But by known
Method directly reclaims them from transudate can not obtain product with competitive cost, and this product does not has in transudate
Various pollutant, especially relate to nitridation and containing the compound of ammonia, be therefore unsuitable for being similar to be obtained by preceding method
The purposes of the humus obtained.
Summary of the invention
It is an object of the present invention to provide a kind of method, it can obtain with the transudate of similar refuse from S.U.R. rubbish
Can the humus of sales volume, be simultaneously achieved reagent (acid, additive) less consumption and use simple technique, it can be whole
Close and use prior art, realizing low investment and operating cost.
In order to reach this target, it is necessary to consider following content.
Humus concentration in transudate changed along with the time (age) of S.U.R. rubbish activity;Known continuous print is raw
Thing degradation period (once toppling over, i.e. occur on the organic component of refuse) is as follows:
The aerobic biological degradation of-initial temporary stage, this is mainly due to the oxygen in gap, produces little during this period
Transudate or humus;
The anaerobic degradation of the-the second long periods, itself is divided into following successive stages:
A) give birth to acid phase, wherein form volatile fatty acid and carbon dioxide by fermentation, and pH value reduces subsequently.?
Acid ph value (5-6) defines a large amount of transudate, and it has high BOD5, high salt concentration, mobility of heavy metals, but exist relatively low
Humus;
B) generating the acetic acid stage, wherein define volatile short chain acid by fermentation, they enter by generating acetic acid bacteria
One step is degraded into acetic acid, the substrate of methane-producing bacteria.Create methane, reduce hydrogen and carbon dioxide, and pH value increases.This oozes
Go out liquid and there is the metal lower than earlier stage and BOD5Concentration, and increase humus and ammonia density;
C) methane phase is generated, wherein by (hydrogenophilic) of hydrogen methanogenic, close that be dominant and especially
Parent (acetophilic) antibacterial of acetyl and form methane (methane of 70% thus generates) in a large number.The feature in this stage exists
In rubbish " ripening ": transudate has neutral-alkaline pH value (7-10);Low volatile acid and the solid concentration of dissolving are (low
BOD5), low heavy metal (such as Fe, Zn) activeness, high ammonia density, maximum humus concentration.
From the transudate of " ripening " rubbish actually by its humus typical dark-brown (HA brown-black;FA
Yellow-brown) can visual identification.By physico-chemical analysis (spectrogrph, UV, FTIR, NMR etc.) available from different S.U.R. rubbish
The chemistry carried out on the humus of transudate and structural property are studied it has been shown that they are similar to, but be not equal to by from
In leonardite, mud coal, brown coal, compost extract and obtain those.
In the purification to rubbish transudate, humus mainly together with the hydroxide of heavy metal and subcarbonate,
By with aluminum and iron salt, calcium hydroxide, organic coagulant etc., carrying out precipitating/clarify wadding by membrane technology skill (ultrafiltration, reverse osmosis)
Coagulate and remove, but this film is easily blocked by humus.This transudate purifies produced mud and is typically recycled to soot
Or otherwise dispose, it for reclaim enough commercial qualities humus for be not economy easily.
" ripening " transudate has been alkalescence humus solution, and is divided into generally according to Italy and European directive
" transudate refuse, specific benign " (CER code 190703).Additionally provide a kind of feasible inceptive filtering to guarantee to appoint
What " solid of suspension " is in low-level, less than 500mg/L, organic trace contaminant of some danger known such as polychlorostyrene hexichol
And two English and polychlorostyrene dibenzofurans (if present) be almost adsorbed onto in particulate matter (suspended solid).
It is an object of the present invention to reclaim humus from this solution, and purify any pollutant (its that they are existing
Make them unsuitable for each particular use).
If in the present invention it has been found that by with the ripening transudate of mineral acid such as sulfuric acid treatment pH value 7-10 until
Precipitate completely at pH value 2-2.5 humus, replace with and the most under vacuo transudate is being concentrated 10-20 take second place by evaporation
After, this transudate carries out identical operation, then it is enough for using following mineral acid quantity: this amount is identical equal in process
During the transudate of non-concentrated of amount 1/4th of amount used.This concrete acid consume be reduced to about 1/4th be by
During concentration processes, significantly reduce what the basicity of transudate realized, this is because generally with high concentration in ripening transudate
The bicarbonate particularly ammonium hydrogen carbonate thermal decomposition ammonification existed and carbon dioxide, then it removed from transudate by evaporation
Go.
Another advantage carrying out humus Acid precipitation on the transudate being such as concentrated under vacuum by evaporation is dense
Contracting transudate and therefore the most there is not possible volatile contaminant in the humus therefrom precipitated, either has
Machine (carboxylic acid, hydrocarbon, other aliphatic series/aromatics organic substance, including halo and nitridation) or inorganic (mainly ammonia);This
Promote humus cleansing phase subsequently, to obtain the humus of commercial quality.
Another advantage is can to ooze out in the concentration discharged from vaporizer at 50-100 DEG C in the stage of humus Acid precipitation
The temperature heat of liquid is carried out, and without other cost of energy, thus improve the efficiency of precipitate morphology and subsequent stage: Gu-
Liquid separate and with water (possibility with mineral acid acidified to pH value < 7) cleaning, reducing impurity such as inorganic salt and water solublity has
Machine compound.
Being in evaporation process concentrating another advantage of operation on transudate, it have passed through at the heat of 50-130 DEG C of temperature
Reason lasts high mean residence time (2-7 hour), and reduces initial bacteria load capacity subsequently, and this is also being acidified to pH value 2
Next stage in reduce further, it is thus achieved that there is no dangerous bacteria such as escherichia coli (Escherichia coli)
Product with Salmonella (salmonella).
Finally, except favourable economic implications (humus is a kind of value product, its except aforementioned exercise use it
Outward, other gainful application also can be found in future) outside, the present invention also has sizable environmental effect, and this is
Because it reclaims the most economic compatible material from refuse, this material is particularly useful for reclaiming and improve barren and/or stream
The soil lost, this is conducive to carbon dioxide conversion to become to be intended for use food purpose or for forming the plant life of regenerative resource
Material, and reduce the discharge to air of this greenhouse gases subsequently.
This target is according to the present invention, by reclaiming humus from the transudate deriving from urban solid garbage field etc.
Method realizes.
