Description
Technical field
It is molten in particular to a kind of carbon source from agriculture derivative the present invention relates to technical field of sewage
Liquid and its preparation method and application.
Background technology
《Water prevention and cure of pollution action plan》(ten, water) and the environmental protection planning of country 13 propose：It is big to the year two thousand twenty whole nation seven
Water quality excellent (reaching or better than III class) ratio in major river valley totally reaches more than 70%, and ground level and above completed region of the city are black smelly
Water body is controlled within 10%.The environmental standard of continuous improvement proposes sewage disposal the requirement of higher, i.e. sanitary sewage
Handle water outlet and implement integrally level-one emission standard A, more there is very water outlet to be up to IV class of grass root's or accurate III class standard.
China's sewage generally existing content of organics is relatively low, and the higher feature of nitrogen and phosphorus content can not using conventional denitrification process
Meet the needs of denitrification stage is to carbon source, cause denitrification process to be obstructed, and suppress heterotrophism aerobic bacteria propagation so that ammonia nitrogen
Assimilation declines, and leverages the denitrification effect of sewage disposal.It was verified that it is to solve this in sewage disposal to add carbon source
The main means of class problem, methanol, glucose, sucrose, acetic acid, sodium acetate etc. are the most common additional carbons of sewage treatment plant.
Methanol has high COD equivalents and shelf-life factory, but its is inflammable, and steam can form explosive mixture with air, quick-fried
Fried limit 6.0%-36.5%, it is poisonous can direct infringer limbs cell tissue, particularly infringement optic nerve nethike embrane causes
Blindness.Therefore the cost of the storage of methanol, medicine system and safety measure input is higher and there are security risk.High concentration vinegar
Acid equally exists inflammable and explosive danger, therefore the acetic acid of generally use 20%-30% or sodium acetate are as carbon source, its COD
Equivalent is only 300000mg/L or so, and can produce crystallization in the case of temperature reduction, influences system operation.Dextrose and saccharose is normal
Using technical grade, a large amount of impurity for being difficult to biological utilisation are included, its purity and COD equivalents substantially reduce, and temperature also can when reducing
Crystallization is produced, influences system operation.In addition, sewerage adds above-mentioned carbon source, microorganism needs certain laundering period.
The content of the invention
The present invention is intended to provide it is a kind of from carbon source solution of agriculture derivative and its preparation method and application, to solve
Security risk existing for carbon source or technical problem of high cost in the prior art.
To achieve these goals, according to an aspect of the invention, there is provided a kind of carbon from agriculture derivative
Source solution.The carbon source solution includes the component of following mass percentage：Agriculture derivative carbon source material 20~30%；Dissolving and
Freezing point depressant 40%~55%；PH adjusting agent 0~2%；Accelerating agent 0~1%；Water 20~30%.
Further, agriculture derivative carbon source material is to be decomposed by agricultural products under the action of heating, acid or enzyme
With the carbon source material obtained after hydrolysis, including glucose, sucrose, lactose, molasses, fructose, maltose, dextrin class, starch, sugar
The one or more of slurry.
Further, dissolving and freezing point depressant are the accessory substances of animals and plants fat soapmaking, including in ethylene glycol, glycerols
It is one or more.
Further, pH adjusting agent is the natural organic acids that plant is formed, including acetic acid, citric acid, malic acid, corydalis tuber
One or more in acid and long shot acid.
Further, accelerating agent is one in short-chain alcohols material, including methanol, ethanol, propyl alcohol class and fourth alcohols material
Kind is a variety of.
According to another aspect of the present invention, there is provided a kind of preparation method of any of the above-described kind of carbon source solution.The preparation side
Method comprises the following steps：Agriculture derivative carbon source material, dissolving and freezing point depressant and water three is mutually mixed with random order
Close, stir while adding to being mixed thoroughly, obtain mixed liquor；Accelerating agent is slowly added into mixed liquor again, stirring is equal
It is even；And pH adjusting agent is added in mixed liquor, pH of mixed is adjusted to 4.5-5.8, is stirred evenly, is obtained carbon source solution.
According to another aspect of the invention, there is provided a kind of any of the above-described kind of carbon source solution in the treatment of waste water should
With.
Further, using including：Carbon source in supplementary carbon source, denitrification process is used as in the case of biochemical carbon source deficiency
Make when starting when insufficient as supplementary carbon source, sewage disposal system as when adding carbon source, aerobic or anaerobic system operation exception
For microbe carbon source.
The present invention at least has the following advantages from the carbon source solution of agriculture derivative：1) COD equivalents can be up to
More than 1000000mg/L, is more than 3 times of carbon source used in sewage plant routine；2) safe and stable, environmental-friendly non-danger is belonged to
Dangerous carbon source；3) solidification point is low (can be less than -18 DEG C), and application region scope is wide；4) can all be bioavailable, and activated sludge
Laundering period it is short, denitrification effect is more preferable.
Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below in conjunction with embodiment, the present invention will be described in detail.
For security risk existing for carbon source in the prior art or technical problem of high cost, the present invention proposes following skill
Art scheme.
A kind of a kind of typical embodiment according to the present invention, there is provided carbon source solution from agriculture derivative.The carbon
Source solution includes the component of following mass percentage：Agriculture derivative carbon source material 20~30%；Dissolving and freezing point depressant
40%~55%；PH adjusting agent 0~2%；Accelerating agent 0~1%；Water 20~30%.The carbon source solution non-corrosiveness, it is non-combustible,
Winter does not crystallize, and can all be bioavailable, and belongs to not dangerous property carbon source.Solving conventional methanol/ethanol has dangerous, second
The problem of acid/sodium acetate/cerelose equivalent COD is low and impurity is high, traditional carbon source north of china in winter easily crystallizes.
