Description
Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of method of molasses containing waste water decoloration.
Background technology
It is difficult the organic wastewater degraded that molasses containing waste water, which is a kind of,.It refer to using molasses as raw material it is fermented after, zymotic fluid exists
The waste water that primary distillation tower discharges after distilling out, but the waste water discharged（Frequently referred to molasses waste liquid）In have accumulated it is a large amount of, complicated, stable,
It is not easy the pigment being degraded, mainly has melanoidin pigment, caramel colorant and phenol sulfonate etc., wherein melanoidin pigment is sugar and ammonia
Maillard reaction occurs for base acid and a kind of brown polymer for being formed, because its is complicated and strong anti-oxidation be most difficult to degradation and
The industries such as other dyestuffs are similar, and pigment removes the development that equally annoying molasses industry, therefore successively many administering methods occurs,
Such as agriculture fills method, oxidation pond process, concentration method, anaerobic process, aerobic method, one aerobic method of anaerobism, chemical flocculation, wherein passing through
The metabolism of microorganism remove this kind of macromolecular substances difficult to degrade of pigment have mild condition, it is safe and effective, environmental-friendly,
The advantages that cost is relatively low, but traditional anaerobic-aerobic processing can cut down COD and BOD, to coloring matter difficult to degrade but not to difficulty
Degradation coloring matter but cannot be removed effectively.
There are some reports both at home and abroad for the research of the biological decolouring of molasses containing waste water at present.In terms of bacterium, report has
Pseudomonas fluorescens, lactobacillus plantarum, uncommon formula lactobacillus etc., wherein percent of decolourization highest of the uncommon formula lactobacillus to simulation molasses containing waste water
Reach 40%；In terms of fungi, report has manyzoned polypore bacteria, Phanerochaete chrysosporium, aspergillus niger, aspergillus fumigatus, aspergillus flavus, streptomycete
Deng.Pant etc. decolourizes to the molasses containing waste water after Anaerobic Treatment using one plant of aspergillus flavus, and 28 days percent of decolourizations reach
74.67%, the degradation enzyme solution extracted from this thalline is reachable to the percent of decolourization of the molasses containing waste water of undiluted Anaerobic Treatment
29.44%.It is 64% to melanoidin percent of decolourization that Murata etc., which is reported under a streptomycete TT14 optimal culture conditions,.The country exists
Research in terms of molasses containing waste water biological decolouring is at the early-stage, studies strain at present and is only limitted to manyzoned polypore bacteria, such as Ran Yanhong is reported
One plant of manyzoned polypore bacteria is 50% to the percent of decolourization of 20% molasses waste liquid under shake flask culture conditions, it can be seen that simple biology is de-
The decolorizing efficiency of color is low, and of high cost.
Invention content
The technical problems to be solved by the invention：Low for the method efficiency of current molasses containing waste water decoloration, of high cost asks
Topic, the present invention provides a kind of methods of molasses containing waste water decoloration.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of method of molasses containing waste water decoloration, this method comprises the following steps：
（1）By molasses containing waste water and based process soil in mass ratio 7~9:1 is uniformly mixed, and is put into processing pond, encapsulation process pond,
It is 28~33 DEG C to keep the temperature in processing pond, is stirred 2~4 days, and removal sealing stands 1~3 day；
（2）After standing, the processing material of molasses containing waste water quality 20~30% is added into processing pond, at 30~35 DEG C,
Encapsulation process pond is warming up to 80~85 DEG C after stirring 1~2h, stirs 10~15h, adds the double of processing material quality 40~45%
Oxygen water mixes 20~25h of conjunction at 45~50 DEG C；
（3）It stands, filters in the case where after mixing, being cooled to 8~12 DEG C, collection filtered fluid, adjusting filtered fluid pH to neutrality, with
It is stood at 4~6 DEG C again afterwards, and uses ultraviolet light, filtering collects filtrate to get the molasses containing waste water after decoloration.
Preferably, the step（1）The preparation of middle based process soil includes the following steps：
A1. it counts in parts by weight, takes 80~90 parts of composite soils, 28~32 parts of water, 22~26 parts of glucose, 20~30 portions of sugarcanes
Slag, 16~19 portions of sucrose, 8~10 parts of sodium chloride, 1~3 part of potassium dihydrogen phosphate and 1~3 part of ammonium hydrogen sulfate, stir evenly, obtain base
Plinth object；
A2. base is put into container, adjusting pH to 5.0~6.5, in sealing container, temperature is 26~35 in holding container
DEG C, it is stirred 3~5 days with 120r/min, the substance in container is freeze-dried, collect dried object, crushed, is sieved, collected
Particle be sieved to get based process soil.
Preferably, composite soil is in mass ratio 1 in the step A1:3~5, peat soil and fertile soil are mixed.
Preferably, the step（2）Middle processing material is in mass ratio 6:1 is uniformly mixed aluminium ash with tailing pickle liquor, i.e.,
Material must be handled.
Compared with other methods, advantageous effects are the present invention：
（1）The present invention is used as bacterium source using peat soil and fertile soil as composite soil by microorganism fungus kind abundant in composite soil,
Early period by culture, enriches the strain in composite soil, and strain is made to adapt to the environment in waste water, by using mixed after enrichment
Soil is closed to pre-process waste water, tentatively decolourized by microorganism, while micro calcium, magnesium being precipitated in composite soil etc. from
Colloid carbohydrate is combined in son, with waste water, and carboxyl abundant in composite soil, hydroxyl isoreactivity functional group in waste water
The substances such as caramel colorant are combined, and reduce coloration, while increasing the activity of pigment, and composite soil itself has certain suction
Flocculated effect is echoed, further decolorization has been carried out to waste water；
（2）The invention of this hair increases processing material, and the combination of metal ion and wherein pigment by going out material increases the matter of pigment
Amount improves settling property, and due to the addition of aluminium ion, iron ion and calcium ion, reduces the steady of caramel colorant in waste water
Qualitative energy, and at a certain temperature, a large amount of sulfate radical polymerize forming polymeric aluminum sulfate iron with metal ion in waste water
Class flocculant, flocculates to pigment, due to a large amount of active group of pigment adsorption, increases flocculating effect, improves
Decolorizing efficiency, while hydrogen peroxide has been used, one side hydrogen peroxide has effects that sterilization bleaching, on the other hand passes through hydrogen peroxide
Effect makes metal ion therein form colloid and is settled, pigment further decreased, and form hydrated alumina, in purple
Waste water is purified under the irradiation of outside line, and since early period activates pigment, improves clean-up effect, while low temperature
Processing reduces pigmentolysis degree, makes its precipitation, to be further processed waste water.
（3）The present invention realizes the effect of the treatment of wastes with processes of wastes against one another, reduces processing cost, while cooperateing with the effect of microorganism, significantly
Improve decolorizing effect.
Specific implementation mode
Handle the preparation of material：In mass ratio 6:1 by aluminium ash and tailing pickle liquor（Jinchuan Group Co., Ltd's chemical plant tailing
